  • 3 Chinese astronauts return to Earth after 6-month mission

    3 Chinese astronauts return to Earth after 6-month mission

    [ad_1]

    BEIJING — Three Chinese astronauts landed in a northern desert on Sunday after six months working to complete construction of the Tiangong station, a symbol of the country’s ambitious space program, state TV reported.

    A capsule carrying commander Chen Dong and astronauts Liu Yang and Cai Xuzhe touched down at a landing site in the Gobi Desert in northern China at approximately 8:10 p.m. (1210 GMT), China Central Television reported.

    Prior to departure, they overlapped for almost five days with three colleagues who arrived Wednesday on the Shenzhou-15 mission for their own six-month stay, marking the first time China had six astronauts in space at the same time. The station’s third and final module docked with the station this month.

    The astronauts were carried out of the capsule by medical workers about 40 minutes after touchdown. They were all smiles, and appeared to be in good condition, waving happily at workers at the landing site.

    “I am very fortunate to have witnessed the completion of the basic structure of the Chinese space station after six busy and fulfilling months in space,” said Chen, who was the first to exit the capsule. “Like meteors, we returned to the embrace of the motherland.”

    Liu, another of the astronauts, said that she was moved to see relatives and her fellow compatriots.

    The three astronauts were part of the Shenzhou-14 mission, which launched in June. After their arrival at Tiangong, Chen, Liu and Cai oversaw five rendezvous and dockings with various spacecraft including one carrying the third of the station’s three modules.

    They also performed three spacewalks, beamed down a live science lecture from the station, and conducted a range of experiments.

    The Tiangong is part of official Chinese plans for a permanent human presence in orbit.

    China built its own station after it was excluded from the International Space Station, largely due to U.S. objections over the Chinese space programs’ close ties to the People’s Liberation Army, the military wing of the ruling Communist Party.

    With the arrival of the Shenzhou-15 mission, the station expanded to its maximum weight of 100 tons.

    Without attached spacecraft, the Chinese station weighs about 66 tons — a fraction of the International Space Station, which launched its first module in 1998 and weighs around 465 tons.

    With a lifespan of 10 to 15 years, Tiangong could one day be the only space station still up and running if the International Space Station retires by around the end of the decade as expected.

    China in 2003 became the third government to send an astronaut into orbit on its own after the former Soviet Union and the United States.

    China has also chalked up uncrewed mission successes: Its Yutu 2 rover was the first to explore the little-known far side of the moon. Its Chang’e 5 probe also returned lunar rocks to Earth in December 2020 for the first time since the 1970s, and another Chinese rover is searching for evidence of life on Mars.

    Officials are reported to be considering an eventual crewed mission to the moon, although no timeline has been offered.

  • Tesla delivers electric semis to PepsiCo at Nevada factory

    Tesla delivers electric semis to PepsiCo at Nevada factory

    [ad_1]

    DETROIT — Tesla delivered its first electric semis to PepsiCo Thursday, more than three years after Elon Musk said his company would start making the trucks.

    The Austin, Texas, company formally delivered the trucks at a factory near Reno, Nevada. The event was livestreamed on Twitter, which Musk now owns.

    Musk drove one of three Tesla Semis in front of a crowd inside the factory. One was white, one was painted with a Pepsi logo, and another with Frito-Lay colors.

    PepsiCo, which is based in Purchase, New York, is taking part in a zero-emissions freight project at a Frito-Lay facility in Modesto, California. That project is being funded by a $15.4 million clean-freight technology grant from the California Air Resources Board that includes 15 Tesla battery-electric tractors and other electric- and natural-gas powered trucks.

    Electric semis also would be eligible for a federal tax credit of up to $40,000.

    At an event in November of 2017 unveiling the Tesla Semi, Musk said production would begin in 2019 and the trucks would be able to follow each other autonomously in a convoy. But during Tesla’s third-quarter earnings conference call in October he said the company’s “Full Self Driving” system is not quite ready to be driverless.

    Musk said the truck has a range per charge of 500 miles (800 kilometers) when pulling an 82,000-pound (37,000-kilo) load. The company plans to ramp up Semi production to make 50,000 trucks in 2024 in North America.

    Competitors working on hydrogen-powered semis say battery-powered trucks won’t work for long-haul carriers because it will take too long to recharge the huge batteries. Musk said hydrogen isn’t needed for heavy trucking.

  • EPA seeks to mandate more use of ethanol and other biofuels

    EPA seeks to mandate more use of ethanol and other biofuels

    [ad_1]

    MINNEAPOLIS — The Environmental Protection Agency on Thursday proposed increasing the amount of ethanol and other biofuels that must be blended into the nation’s fuel supplies over the next three years, a move welcomed by renewable fuel and farm groups but condemned by environmentalists and oil industry groups.

    “This proposal supports low-carbon renewable fuels and seeks public input on ways to strengthen the program,” EPA Administrator Michael S. Regan said in a statement. “With this proposal, EPA seeks to provide consumers with more options while diversifying our nation’s energy mix.”

    The proposal also includes new incentives to encourage the use of biogas from farms and landfills, and renewable biomass such as wood, to generate electricity to charge electric vehicles. It’s the first time the EPA has set biofuel targets on its own instead of using numbers from Congress. The agency opened a public comment period and will hold a hearing in January.

    The goal of the existing Renewable Fuel Standard is to reduce carbon emissions that contribute to climate change, expand the country’s fuel supply, strengthen energy security and reduce fuel prices for consumers. Ethanol is a key part of the economy in many Midwest states, consuming about 40% of the nation’s corn supply.

    But environmentalists argue that it’s a net ecological and climate detriment because growing all that corn fosters unsustainable farming practices, while the oil industry says ethanol mandates constrain free market forces and limit consumer choice, and that higher blends can damage older vehicles.

    Geoff Cooper, president and CEO of the Renewable Fuels Association, told reporters on a conference call that the EPA’s plan creates a “clear pathway for sustainable growth for our industry when it comes to the production and use of low-carbon fuels like ethanol.” He said it also bolsters the industry’s push for year-round sales of gasoline with a 15% ethanol blend, as well as sales of the 85% ethanol blend E85.

    “As the administration is working to address climate change, we’ve long known that biofuels will play an important role in reducing greenhouse gases while having the added benefit of providing expanded opportunities for farmers,” National Farmers Union President Rob Larew said in a statement.

    But environmental groups said the plan offers false solutions to climate change.

    “This is a toxic plan directly at odds with the Biden Administration’s commitment to Environmental Justice,” Sarah Lutz, climate campaigner at Friends of the Earth, said in a statement. “Charging electric vehicles with forests and factory farms should be a non-starter.”

    Geoff Moody, senior vice president of the American Fuel & Petrochemical Manufacturers said the Renewable Fuel Standard was meant to be a liquid fuels program, not an electric vehicle program. He urged the EPA to go back as it develops the final rule and reject “yet another massive regulatory subsidy for electric vehicle manufacturers.”

    The EPA proposes to set the total target for all kinds of renewable fuels at 20.82 billion gallons for 2023, including 15 billion gallons from corn ethanol. The target would grow to 22.68 billion gallons for 2025, including 15.25 billion gallons of corn ethanol. The plan also calls for growth in cellulosic biofuels — which are made from fibrous plant materials — biomass-based diesel and other advanced biofuels.

    Republican U.S. Sen. Chuck Grassley, of Iowa, the country’s top corn and ethanol producing state, said in a statement that the EPA should have gone further to require even more use of advanced biofuels to move freight, which he said would help lower prices for consumer goods.

    Cooper said there’s probably no way to meet the proposed higher targets without more use of E15 and E85 instead of the conventional 10% ethanol mix. That makes it important to eliminate regulations that block summertime sales of E15, he said.

    So, he predicted, the EPA’s proposal should bolster prospects for legislation introduced this week by Democratic U.S. Sen. Amy Klobuchar, of Minnesota, and GOP Sen. Deb Fischer, of Nebraska, to allow year-round sales of E15 nationwide. E15 sales are usually prohibited between June 1 and Sept. 15 because of concerns that it adds to smog in high temperatures.

    Eight Midwest governors asked the EPA in April to allow year-round sales of E15 in their states. But Cooper said the new bill would provide a “nationwide fix” that even the American Petroleum Institute considers preferable to the current patchwork of temporary waivers and ad hoc solutions.

  • China prepares to send new 3-person crew to space station

    China prepares to send new 3-person crew to space station

    [ad_1]

    BEIJING — Final preparations were being made Monday to send a new three-person crew to China‘s space station as it nears completion amid intensifying competition with the United States.

    The China Manned Space Agency said the Shenzhou-15 mission will take off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert at 11:08 p.m. Tuesday night.

    The six-month mission, commanded by Fei Junlong and crewed by Deng Qingming and Zhang Lu, will be the last “in the construction phase of China’s space station,” agency official Ji Qiming told reporters Monday.

    Fei, 57, is a veteran of the 2005 four-day Shenzhou-6 mission which was the second in which China sent a human into space. Deng and Zhang are flying in space for the first time.

    The station’s third and final module docked with the station earlier this month, one of the last steps in a more than decade-long effort to maintain a constant crewed presence in orbit.

    The astronauts will overlap briefly onboard the station, named Tiangong, with the previous crew, who arrived in early June for a six-month stay.

    Tiangong has room to accommodate six astronauts at a time. Previous missions to the space station have taken about 13 hours from liftoff to docking.

    Next year, China plans to launch the Xuntian space telescope, which, while not part of Tiangong, will orbit in sequence with the station and can dock occasionally with it for maintenance.

    No other future additions to the space station have been publicly announced.

    The permanent Chinese station will weigh about 66 tons — a fraction of the International Space Station, which launched its first module in 1998 and weighs around 465 tons.

    With a lifespan of 10 to 15 years, Tiangong could one day find itself the only space station still running if the International Space Station adheres to its 30-year operating plan.

    China’s crewed space program is officially three decades old this year, but it truly got underway in 2003, when China became only the third country after the U.S. and Russia to put a human into space using its own resources.

    The program is run by the ruling Communist Party’s military wing, the People’s Liberation Army, and has proceeded methodically and almost entirely without outside support. The U.S. excluded China from the International Space Station because of its program’s military ties.

    China has also chalked up successes with uncrewed missions, and its lunar exploration program generated media buzz last year when its Yutu 2 rover sent back pictures of what was described by some as a “mystery hut” but was most likely only a rock. The rover is the first to be placed on the little-explored far side of the moon.

    China’s Chang’e 5 probe returned lunar rocks to Earth for the first time since the 1970s in December 2000 and another Chinese rover is searching for evidence of life on Mars. Officials are also considering a crewed mission to the moon.

    No timeline has been offered for a crewed lunar mission, even as NASA presses ahead with its Artemis lunar exploration program that aims to send four astronauts around the moon in 2024 and land humans there as early as 2025.

    China’s space program has also drawn controversy. Beijing brushed off complaints that it has allowed rocket stages to fall to Earth uncontrolled after NASA accused it of “failing to meet responsible standards regarding their space debris” when parts of a Chinese rocket landed in the Indian Ocean.

    China’s increasing space capabilities also feature in the latest Pentagon defense strategy.

    “In addition to expanding its conventional forces, the PLA is rapidly advancing and integrating its space, counterspace, cyber, electronic, and informational warfare capabilities to support its holistic approach to joint warfare,” the strategy said.

    The U.S. and China are at odds on a range of issues, especially self-governing Taiwan, which Beijing threatens to annex with force. China responded to a September visit to Taiwan by U.S. House Speaker Nancy Pelosi by firing missiles over the island, holding wargames in surrounding waters and staging a simulated blockade, something that could trigger an American military response.

  • Ford recalls over 634K SUVs due to fuel leaks and fire risk

    Ford recalls over 634K SUVs due to fuel leaks and fire risk

    [ad_1]

    DEARBORN, Mich. — Ford Motor Co. is recalling over 634,000 SUVs worldwide because a cracked fuel injector can spill fuel or leak vapors onto a hot engine and cause fires.

    The recall covers Bronco Sport and Escape SUVs from the 2020 through 2023 model years. All have 1.5-liter, three-cylinder engines.

    The Dearborn, Michigan, automaker said Thursday it’s not recommending that owners stop driving the vehicles or park them outdoors because fires are rare and generally don’t happen when the engines are off.

    But Ford said it has received 20 reports of fires, including three that ignited nearby structures. The company also said it has four claims of fires that were noticed less than five minutes after the engines were turned off. Ford also has four injury claims not involving burns, and 43 legal claims attributed to the problem.

    Repairs aren’t yeta available, but once they are, owners should schedule service with a preferred dealer, Jim Azzouz, executive director of customer experience, said in a statement. Owners will be notified by letter starting Dec. 19.

    Owners can take their SUVs to the dealer and get a free loaner, or they can get free pickup and delivery.

    Dealers will inspect the injectors and replace them if necessary. Ford also says it’s extending warranties to cover cracked fuel injectors for up to 15 years.

    Dealers will update the vehicles’ engine-control software so it detects a cracked injector. Drivers will get a dashboard message to get service. Also, if there’s a pressure drop in the injectors, engine power will be cut to minimize risk and let drivers get to a safe location to stop and call for service, Ford said.

    They’ll also install a tube to drain fuel from the cylinder head and away from hot surfaces.

    Ford said it’s not replacing the injectors because the failure rate that causes leaks is low, an estimated 0.38% for 2020 models and 0.22% for 2021 to 2022 models. The rate is for 15 years or 150,000 miles (240,000 kilometers).

  • NASA’s mightiest rocket lifts off 50 years after Apollo

    NASA’s mightiest rocket lifts off 50 years after Apollo

    [ad_1]

    CAPE CANAVERAL, Fla. — NASA’s new moon rocket blasted off on its debut flight with three test dummies aboard Wednesday, bringing the U.S. a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo program 50 years ago.

    If all goes well during the three-week, make-or-break shakedown flight, the crew capsule will be propelled into a wide orbit around the moon and then return to Earth with a Pacific splashdown in December.

    After years of delays and billions in cost overruns, the Space Launch System rocket thundered skyward, rising from Kennedy Space Center on 8.8 million pounds (4 million kilograms) of thrust and hitting 100 mph (160 kph) within seconds. The Orion capsule was perched on top and, less than two hours into the flight, busted out of Earth’s orbit toward the moon.

    “It’s a great day,” said NASA Administrator Bill Nelson.

    The moonshot follows nearly three months of vexing fuel leaks that kept the rocket bouncing between its hangar and the pad. Forced back indoors by Hurricane Ian at the end of September, the rocket stood its ground outside as Nicole swept through last week with gusts of more than 80 mph (130 kph). Although the wind caused some damage, managers gave the green light for the launch.

    An estimated 15,000 people jammed the launch site, with thousands more lining the beaches and roads outside the gates, to witness NASA’s long-awaited sequel to Project Apollo, when 12 astronauts walked on the moon from 1969 and 1972. Crowds also gathered outside NASA centers in Houston and Huntsville, Alabama, to watch the spectacle on giant screens.

    Cheers accompanied the rocket as it rode a huge trail of flames toward space, with a half-moon glowing brightly and buildings shaking as though hit by a major quake.

    “For the Artemis generation, this is for you,” launch director Charlie Blackwell-Thompson called out, referring to all those born after Apollo.

    The liftoff marked the start of NASA’s Artemis lunar-exploration program, named after Apollo’s mythological twin sister. The space agency is aiming to send four astronauts around the moon on the next flight, in 2024, and land humans there as early as 2025.

    “You have earned your place in history,” Blackwell-Thompson told her team following liftoff.

    The 322-foot (98-meter) SLS is the most powerful rocket ever built by NASA, with more thrust than either the space shuttle or the mighty Saturn V that carried men to the moon. A series of hydrogen fuel leaks plagued the summertime launch attempts as well as countdown tests. A fresh leak erupted at a new location during Tuesday night’s fueling, but an emergency team managed to tighten the faulty valve on the pad. Then a U.S. Space Force radar station went down, resulting in another scramble, this time to replace an ethernet switch.

    “The rocket, it’s alive. It’s creaking. It’s making venting noises. It’s pretty scary. … My heart was pumping. My nerves were going,” said Trent Annis, one of the three men who entered the blast danger zone to fix Tuesday night’s leak.

    Orion should reach the moon by Monday, more than 230,000 miles (370,000 kilometers) from Earth. After coming within 80 miles (130 kilometers) of the moon, the capsule will enter a far-flung orbit stretching about 40,000 miles (64,000 kilometers) beyond.

    The $4.1 billion test flight is set to last 25 days, roughly the same as when crews will be aboard. The space agency intends to push the spacecraft to its limits and uncover any problems before astronauts strap in. The mannequins — NASA calls them moonequins — are fitted with sensors to measure such things as vibration, acceleration and cosmic radiation.

    The rocket was supposed to have made its dry run by 2017. Government watchdogs estimate NASA will have spent $93 billion on the project by 2025.

    Ultimately, NASA hopes to establish a base on the moon and send astronauts to Mars by the late 2030s or early 2040s.

    But many hurdles still need to be cleared. The Orion capsule will take astronauts only to lunar orbit, not the surface.

    NASA has hired Elon Musk’s SpaceX to develop Starship, the 21st-century answer to Apollo’s lunar lander. Starship will carry astronauts back and forth between Orion and the lunar surface, at least on the first trip in 2025. The plan is to station Starship and eventually other companies’ landers in orbit around the moon, ready for use whenever new Orion crews pull up.

    Reprising an argument that was made during the 1960s, Duke University historian Alex Roland questions the value of human spaceflight, saying robots and remote-controlled spacecraft could get the job done more cheaply, efficiently and safely.

    “In all these years, no evidence has emerged to justify the investment we have made in human spaceflight — save the prestige involved in this conspicuous consumption,” he said.

    NASA is waiting until this test flight is over before introducing the astronauts who will be on the next one and those who will follow in the bootsteps of Apollo 11′s Neil Armstrong and Buzz Aldrin.

    Most of NASA’s corps of 42 active astronauts and 10 trainees were not even born yet when Apollo 17 moonwalkers Gene Cernan and Harrison Schmitt closed out the era, 50 years ago next month.

    “We are jumping out of our spacesuits with excitement,” astronaut Christina Koch said Tuesday.

    After a nearly yearlong space station mission and all-female spacewalk, Koch, 43, is on NASA’s short list for a lunar flight. So is astronaut Kayla Barron, 35, who finally got to witness her first rocket launch, not counting her own a year ago.

    “It took my breath away, and I was tearing up,” Barron said. “What an amazing accomplishment for this team.”

  • New Zealand targets cow burps to help reduce global warming

    New Zealand targets cow burps to help reduce global warming

    [ad_1]

    PALMERSTON NORTH, New Zealand — How do you stop a cow from burping?

    It might sound like the start of a humorous riddle, but it’s the subject of a huge scientific inquiry in New Zealand. And the answer could have profound effects on the health of the planet.

    More specifically, the question is how to stop cows, sheep and other farm animals from belching out so much methane, a gas which doesn’t last as long as carbon dioxide in the atmosphere but is at least 25 times more potent when it comes to global warming.

    Because cows can’t readily digest the grass they eat, they ferment it first in multiple stomach compartments, or rumen, a process that releases huge amounts of gas. Every time somebody eats a beef burger or drinks a milkshake, it comes at an environmental cost.

    New Zealand scientists are coming up with some surprising solutions that could put a big dent in those emissions. Among the more promising are selective breeding, genetically modified feed, methane inhibitors, and a potential game-changer — a vaccine.

    Nothing is off the table, from feeding the animals more seaweed to giving them a kombucha-style probiotic called “Kowbucha.” One British company has even developed a wearable harness for cows that oxidizes methane as it’s burped out.

    In New Zealand, the research has taken on a new urgency. Because farming is central to the economy, about half of the nation’s greenhouse gas emissions come from farms, compared to less than 10% in the U.S. New Zealand’s 5 million people are outnumbered by 26 million sheep and 10 million cattle.

    As part of a push to become carbon neutral, New Zealand’s government has promised to reduce methane emissions from farm animals by up to 47% by 2050.

    Last month the government announced a plan to begin taxing farmers for animal burps, a world-first move that has angered many farmers. All sides are hoping they might catch a break from science.

    Much of the research is taking place at a Palmerston North campus, which some have jokingly taken to calling Gumboot Valley, in a nod to Silicon Valley.

    “I don’t believe there’s any other place that has the breadth of ambition that New Zealand has in terms of the range of technologies being investigated in any one place,” said Peter Janssen, a principal scientist at AgResearch, a government-owned company that employs about 900 people.

    Underpinning the research are studies indicating that reducing methane doesn’t need to harm the animals or affect the quality of the milk or meat. Janssen said the microbes that live in the animals and produce methane seem to be opportunistic rather than integral to digestion.

    He’s been working on developing a vaccine for the past 15 years and has focused intensively on it for the past five years. He said it has the potential to reduce the amount of methane belched by cows by 30% or more.

    “I certainly believe it’s going to work, because that’s the motivation for doing it,” he said.

    A vaccine would stimulate an animal’s immune system to produce antibodies, which would then dampen the output of the methane-producing microbes. One big upside of a vaccine is that it would likely only need to be administered once a year, or even perhaps even once in an animal’s lifetime.

    Working in a similar way, inhibitors are compounds administered to the animals that directly dampen the methane microbes.

    Inhibitors could also reduce methane by at least 30% and perhaps by up to 90%, according to Janssen. The challenge is that the compounds need to be safe for animal consumption and not pass through the meat or milk to humans. Inhibitors must also be regularly administered.

    Both inhibitors and vaccines are some years away from being market ready, Janssen said.

    But other technologies such as selective breeding, which could reduce methane output by 15%, will be rolled out onto sheep farms as early as next year, Janssen said. A similar program for cows may not be too far behind.

    Scientists have for years been testing sheep in chambers to chart differences in how much methane they belch. The low-emitters have been bred and produced low-emitting offspring. Scientists have also been tracking genetic characteristics common to low-emitting animals that make them readily identifiable.

    “I think one of the areas that New Zealand scientists, particularly, have made some great progress is in this whole area of animal breeding,” said Sinead Leahy, the principal science advisor at the New Zealand Agricultural Greenhouse Gas Research Centre. “And particularly, a lot of research has been done into breeding low emissions sheep.”

    Another target is the feed that animals eat, which scientists believe has the potential for reducing methane output by 20% to 30%.

    At one greenhouse on the campus, scientists are developing genetically modified clover. Visitors must wear booties and medical scrubs and avoid putting down objects to prevent any cross-contamination.

    The scientists explain that because New Zealand farm animals eat outside in fields most of the time rather than in barns, methane-reducing feed additives like Bovaer, developed by Dutch company DSM, aren’t as useful.

    Instead, they are looking to genetically modify the ryegrass and white clover that the New Zealand animals predominantly eat.

    With the clover, scientists have found a way to increase tannins, which helps block methane production.

    “What this team has done is they’ve actually identified, through their research, a master switch that switches on condensed tannins in the leaves,” said Linda Johnson, a science group manager at AgResearch.

    Laboratory analysis indicates the modified clover reduces methane production by 15% to 19%, Johnson said.

    The clover program goes hand-in-hand with a ryegrass program.

    Richard Scott, an AgResearch senior scientist, said they have been able to increase the oil levels in ryegrass leaves by about 2%, which studies indicate should translate to a 10% drop in methane emissions.

    But like the inhibitors and vaccine, the feed program is still some years away from being farm ready. Scientists have completed controlled tests in the U.S. and are planning a bigger field trial in Australia.

    However, New Zealand has strict rules that ban most genetically modified crops, a regulatory barrier that the scientists will need to overcome if they are to introduce the modified feed to the nation’s farms.

    In other research, dairy company Fonterra is trialing its probiotic Kowbucha concoction and British company Zelp is continuing to trial and refine its wearable harnesses. Other trials have indicated that a red seaweed called Asparagopsis reduces methane when eaten by cows.

    But farmers aren’t waiting around for all the research to come to fruition. On the Kaiwaiwai Dairies farm near the town of Featherston, farmer Aidan Bichan said they’ve been reducing their methane output by getting more efficient.

    He said that includes increasing the milk production from each cow, using less processed feed, and replacing milking cows less frequently.

    “At a farm level, we’ve got to do our bit to help save the planet,” Bichan said.

    But other technologies such as selective breeding, which could reduce methane output by 15%, will be rolled out onto sheep farms as early as next year, Janssen said. A similar program for cows may not be too far behind.

    Scientists have for years been testing sheep in chambers to chart differences in how much methane they belch. The low-emitters have been bred and produced low-emitting offspring. Scientists have also been tracking genetic characteristics common to low-emitting animals that make them readily identifiable.

    “I think one of the areas that New Zealand scientists, particularly, have made some great progress is in this whole area of animal breeding,” said Sinead Leahy, the principal science advisor at the New Zealand Agricultural Greenhouse Gas Research Centre. “And particularly, a lot of research has been done into breeding low emissions sheep.”

    Another target is the feed that animals eat, which scientists believe has the potential for reducing methane output by 20% to 30%.

    At one greenhouse on the campus, scientists are developing genetically modified clover. Visitors must wear booties and medical scrubs and avoid putting down objects to prevent any cross-contamination.

    The scientists explain that because New Zealand farm animals eat outside in fields most of the time rather than in barns, methane-reducing feed additives like Bovaer, developed by Dutch company DSM, aren’t as useful.

    Instead, they are looking to genetically modify the ryegrass and white clover that the New Zealand animals predominantly eat.

    With the clover, scientists have found a way to increase tannins, which helps block methane production.

    “What this team has done is they’ve actually identified, through their research, a master switch that switches on condensed tannins in the leaves,” said Linda Johnson, a science group manager at AgResearch.

    Laboratory analysis indicates the modified clover reduces methane production by 15% to 19%, Johnson said.

    The clover program goes hand-in-hand with a ryegrass program.

    Richard Scott, an AgResearch senior scientist, said they have been able to increase the oil levels in ryegrass leaves by about 2%, which studies indicate should translate to a 10% drop in methane emissions.

    But like the inhibitors and vaccine, the feed program is still some years away from being farm ready. Scientists have completed controlled tests in the U.S. and are planning a bigger field trial in Australia.

    However, New Zealand has strict rules that ban most genetically modified crops, a regulatory barrier that the scientists will need to overcome if they are to introduce the modified feed to the nation’s farms.

    In other research, dairy company Fonterra is trialing its probiotic Kowbucha concoction and British company Zelp is continuing to trial and refine its wearable harnesses. Other trials have indicated that a red seaweed called Asparagopsis reduces methane when eaten by cows.

    But farmers aren’t waiting around for all the research to come to fruition. On the Kaiwaiwai Dairies farm near the town of Featherston, farmer Aidan Bichan said they’ve been reducing their methane output by getting more efficient.

    He said that includes increasing the milk production from each cow, using less processed feed, and replacing milking cows less frequently.

    “At a farm level, we’ve got to do our bit to help save the planet,” Bichan said.

  • Some recent fatal crashes involving vintage aircraft

    Some recent fatal crashes involving vintage aircraft

    [ad_1]

    Saturday’s collision between two World War II-era military planes at a Dallas air show was the latest in a long list of crashes involving vintage planes used or designed for military purposes. Some recent fatal crashes in the U.S. and abroad:

    — Oct. 2, 2019: A four-engine, propeller-driven B-17G Flying Fortress bomber with 13 people aboard crashed at Bradley International Airport, north of Hartford, Connecticut, during a traveling vintage aircraft show. Seven people were killed and six were hurt. The National Transportation Safety Board found that pilot error was the probable cause, with inadequate maintenance a contributing factor.

    — Nov. 17, 2018: A privately owned vintage World War II Mustang fighter airport plane crashed into the parking lot of an apartment complex in Fredericksburg, Texas, killing the pilot and a passenger. The P-51D Mustang was returning after performing a flyover during a living history show at the national Museum of the Pacific War. The aircraft was destroyed, and several vehicles in the parking lot were damaged.

    — Aug. 4, 2018: A 79-year-old Junkers Ju-52 plane operated by the Swiss company Ju-Air plunged into the Piz Segnas mountain near the Flims ski resort in eastern Switzerland, killing all 20 on board. Retired from Switzerland’s air force in 1981, the German-built plane was carrying tourists who wanted to take “adventure flights” to experience the country’s landscape in vintage planes. Swiss investigators said that “high-risk flying” by the pilots led to the crash.

    — May 30, 2018: A small vintage airplane that was part of a GEICO stunt team with five other planes crashed in a wooded residential area in Melville, New York, killing the pilot. The World War II-era SNJ-2 aircraft, known as a North American T-6 Texan, had departed from a nearby airport and was heading to Maryland when it crashed.

    — July 16, 2017: A pilot and an airport manager were killed in Cummings, Kansas, after their World War II-era P-51D Mustang “Baby Duck” crashed into a field. Authorities say the pilot was re-creating a stunt he had performed on the prior day at the Amelia Earhart Festival.

    — Jan. 26, 2017: A World War II-era Grumman G-73 Mallard flying boat stalled and nosedived into the Swan River in Perth, Australia, during Australia Day celebrations. Both the pilot and his passenger died.

    — Aug. 27, 2016 — A pilot from Alaska was killed when his 450 Stearman biplane, a World War II-era plane often used for military training, crashed during the Airshow of the Cascades in Madras, Oregon.

    — July 17, 2016 — A T-28 Trojan, used by the U.S. military as a training aircraft beginning in the 1950s and also as a counterinsurgency aircraft during the Vietnam War, crashed at the Cold Lake Air Show in Alberta, killing the pilot. Thousands of spectators witnessed the accident.

    — Aug. 22, 2015 — A 1950s-era Hawker Hunter T7 jet crashed into a busy highway near West Sussex, England, killing 11 and injuring more than a dozen others. Investigators said the pilot, who survived, was flying too low and slowly to successfully complete a loop-the-loop. He was charged with 11 counts of manslaughter but ultimately was cleared.

    — June 22, 2013 — A pilot and a wing-walker were killed when their World War II-era Boeing-Stearman IB75A biplane crashed into the ground and burst into flames during a performance at the Vectren Dayton Air Show in Vandalia, Ohio. Thousands of spectators saw the crash, which federal safety investigators said was likely caused by pilot error.

    — Sept. 16, 2011 — The pilot of a 70-year-old modified P-51D Mustang called the Galloping Ghost lost control of the aircraft at the National Championship Air Races and Air Show in Reno, Nevada, and crashed into spectators, killing 10 and injuring more than 60. The pilot also died. Federal investigators blamed the crash on worn parts and speed.

  • Unmanned, solar-powered US space plane back after 908 days

    Unmanned, solar-powered US space plane back after 908 days

    [ad_1]

    CAPE CANAVERAL, Fla. — An unmanned U.S. military space plane landed early Saturday after spending a record 908 days in orbit for its sixth mission and conducting science experiments.

    The solar-powered vehicle, which looks like a miniature space shuttle, landed at NASA’s Kennedy Space Center. Its previous mission lasted 780 days.

    “Since the X-37B’s first launch in 2010, it has shattered records and provided our nation with an unrivaled capability to rapidly test and integrate new space technologies,” said Jim Chilton, a senior vice president for Boeing, its developer.

    For the first time, the space plane hosted a service module that carried experiments for the Naval Research Laboratory, U.S. Air Force Academy and others. The module separated from the vehicle before de-orbiting to ensure a safe landing.

    Among the experiments was a satellite dubbed the FalconSat-8 that was designed and built by academy cadets in partnership with the Air Force Research Laboratory. It was deployed in October 2021 and still remains in orbit.

    Another experiment evaluated the effects of long-duration space exposure on seeds.

    “This mission highlights the Space Force’s focus on collaboration in space exploration and expanding low-cost access to space for our partners, within and outside of the Department of the Air Force,” said Gen. Chance Saltzman, Chief of Space Operations.

    The X-37Be has now flown over 1.3 billion miles and spent a total of 3,774 days in space.

  • EXPLAINER: Bikes, batteries and blazes spark concern in NYC

    EXPLAINER: Bikes, batteries and blazes spark concern in NYC

    [ad_1]

    NEW YORK — A weekend fire that injured over three dozen people — and forced firefighters to use ropes to pluck people from a 20th-story window — is drawing attention to a rising concern in New York City: battery fires that can arise in the electric bikes and scooters that have proliferated here.

    City officials are considering new laws after the fire department counted nearly 200 blazes and six fire deaths this year tied to problems with lithium-ion batteries in such “micromobility” devices.

    WHAT ARE THESE BATTERIES? ARE THEY THE SAME TECH USED IN PHONES AND CARS?

    Lithium-ion batteries are a Nobel Prize-winning innovation that entered the market in the early 1990s. Hailed as rechargeable, lightweight, powerful, durable and safe, the batteries have been envisioned as a key to greening the world’s energy supply by storing energy, including from the sun, wind and other renewable sources.

    The technology has woven its way into many people’s everyday lives, powering phones, laptop computers, vehicles and more.

    WHY CAN THEY CATCH FIRE?

    The batteries’ electrolyte — a solution that lets electrical current flow — is flammable, explains Massachusetts Institute of Technology materials chemistry professor Dr. Donald Sadoway. The substance was chosen for its ability to handle the voltage involved, but fires can happen if the batteries are overcharged, overheated, defective or damaged, for instance.

    Over the years, problems have periodically triggered fires involving laptops, cellphones, hoverboards, electric vehicles, airplanes and battery power storage installations. A U.N. aviation agency said in 2016 that lithium-ion batteries shouldn’t be shipped on passenger planes.

    Battery industry group leader James Greenberger notes that other energy sources aren’t trouble-free, and he says there’s nothing inherently unsafe about the batteries. But he said the industry is concerned about the fires lately in New York and worries that they could scare off consumers.

    “This shouldn’t be happening and we need to figure out what’s going on,” said Greenberger, the executive director of NAATBatt — the North American trade association for advanced battery technology developers, manufacturers and users.

    WHY ARE E-BIKES AND SCOOTERS GETTING SCRUTINY IN NEW YORK?

    The city has seen “an exponential increase” in fires related to faulty lithium-ion batteries in recent years, Chief Fire Marshal Daniel Flynn said. He said there have been more deaths and injuries already this year than in the past three years combined.

    “It’s a big issue,” he said at a news conference Monday, describing fires that occur without warning, grow rapidly and are tough to extinguish.

    The batteries “fail almost in an explosive way — it’s like a blowtorch,” he said.

    Saturday’s fire in a Manhattan apartment was sparked by a malfunctioning e-bike battery that residents were attempting to charge and left unattended while they fell asleep, he said. They were trapped when the battery, plugged in by the front door, caught fire, Flynn said.

    Electric bikes and scooters have become popular, non-gasoline-burning ways to make deliveries, commute and zip around a city that has promoted cycling in recent decades. For the “deliveristas” who carry restaurant takeout orders, the bikes are crucial tools of the trade.

    “What these workers have learned over the years, and they know it well, is that, like any equipment, it requires the maintenance required,” said Hildalyn Colón Hernández, a spokesperson for worker advocacy group Los Deliveristas Unidos. She said many workers have used their batteries for years without a hitch.

    WHAT’S CAUSING THE PROBLEM?

    There are different opinions. Greenberger, the industry group director, suggests there’s too little quality control on some of the largely imported batteries. Sadoway, the scientist, believes “we don’t have the appropriate protective measures” on e-bikes and scooters themselves to monitor the batteries for problems.

    Colón Hernández, the delivery worker advocate, thinks there need to be tougher standards around the batteries, such as regulations for businesses that sell or service them.

    WHAT IS NEW YORK CITY DOING ABOUT THIS?

    The Fire Department has repeatedly issued warnings and safety tips over the past year. Fire Commissioner Laura Kavanagh asked the federal Consumer Product Safety Commission in August to consider new regulations. Mayor Eric Adams pointed again to the CPSC on Monday.

    “The responsibility of navigating safe and unsafe batteries on the market should not fall to hard-working New Yorkers,” the mayor, a Democrat, said in a statement.

    Some city lawmakers want to take their own steps.

    A City Council committee has set a Nov. 14 hearing on various proposals. Some would require public education campaigns or safety reports. Another would prohibit the sale of some secondhand lithium-ion batteries, or e-bike or scooter batteries without certain seals of approval.

    Meanwhile, fire officials continue to urge everyone not to leave batteries to charge unattended, to check that they’re not damaged or near a heat source, and to make sure the batteries, chargers, cords and devices are all from the same manufacturer and used as instructed.

    “We understand the benefits that these batteries pose to our communities, and we want to encourage use of them, but safe use,” Flynn said. “So understand that it does pose a danger, and just use them safely.”

  • Supplier to hire 630 near Hyundai’s EV plant in Georgia

    Supplier to hire 630 near Hyundai’s EV plant in Georgia

    [ad_1]

    STATESBORO, Ga. — An auto parts manufacturer plans to hire 630 workers at a new factory in southeast Georgia to supply Hyundai Motor Group’s first U.S. electric vehicle plant that’s under construction nearby, state officials said Monday.

    Joon Georgia will invest $317 million to produce parts in Bulloch County, Gov. Brian Kemp’s office said in a news release. The supplier will open shop roughly 30 miles (50 kilometers) west of the southeast Georgia site where Hyundai executives broke ground on the new EV plant two weeks ago.

    The company is “the first of many” expected to come to Georgia to supply the $5.5 billion Hyundai plant in Bryan County, Kemp said in a statement. The automaker plans to open its Georgia plant in 2025, producing up to 300,000 electric vehicles per year.

    Joon Georgia is a subsidiary of Ajin USA, which supplies parts to other Hyundai plants. It already operates a facility in Cusseta, Alabama, near the Georgia line that makes parts for Hyundai’s plant in Montgomery, Alabama, as well as for Kia’s auto plant in West Point, Georgia.

    The Joon Georgia factory near the Hyundai EV plant is expected to open near Statesboro in mid-2024, Kemp’s office said.

    “Joon Georgia’s announcement today is a landmark moment as we drive Georgia’s automotive industry into the future,” said Pat Wilson, commissioner of the Georgia Department of Economic Development, in a statement.

    State and local officials in Georgia lured Hyundai with tax breaks and incentives worth $1.8 billion, making it the state’s largest economic development deal.

    Wilson and other Georgia officials have insisted it’s a worthwhile investment. In addition to Hyundai hiring 8,100 workers, suppliers are expected to create thousands of additional jobs in the state.

  • Two NASA spacecraft detect biggest meteor strikes at Mars

    Two NASA spacecraft detect biggest meteor strikes at Mars

    [ad_1]

    CAPE CANAVERAL, Fla. — Two NASA spacecraft at Mars — one on the surface and the other in orbit — have recorded the biggest meteor strikes and impact craters yet.

    The high-speed barrages last year sent seismic waves rippling thousands of miles across Mars, the first ever detected near the surface of another planet, and carved out craters nearly 500 feet (150 meters) across, scientists reported Thursday in the journal Science.

    The larger of the two strikes churned out boulder-size slabs of ice, which may help researchers look for ways future astronauts can tap into Mars’ natural resources.

    The Insight lander measured the seismic shocks, while the Mars Reconnaissance Orbiter provided stunning pictures of the resulting craters.

    Imaging the craters “would have been huge already,” but matching it to the seismic ripples was a bonus, said co-author Liliya Posiolova of Malin Space Science Systems in San Diego. “We were so lucky.”

    Mars’ atmosphere is thin unlike on Earth, where the thick atmosphere prevents most space rocks from reaching the ground, instead breaking and incinerating them.

    A separate study last month linked a recent series of smaller Martian meteoroid impacts with smaller craters closer to InSight, using data from the same lander and orbiter.

    The impact observations come as InSight nears the end of its mission because of dwindling power, its solar panels blanketed by dust storms. InSight landed on the equatorial plains of Mars in 2018 and has since recorded more than 1,300 marsquakes.

    “It’s going to be heartbreaking when we finally lose communication with InSight,” said Bruce Banerdt of NASA’s Jet Propulsion Laboratory, the lander’s chief scientist who took part in the studies. “But the data it has sent us will certainly keep us busy for years to come.”

    Banerdt estimated the lander had between four to eight more weeks before power runs out.

    The incoming space rocks were between 16 feet and 40 feet (5 meters and 12 meters) in diameter, said Posiolova. The impacts registered about magnitude 4.

    The larger of the two struck last December some 2,200 miles (3,500 kilometers) from InSight, creating a crater roughly 70 feet (21 meters) deep. The orbiter’s cameras showed debris hurled up to 25 miles (40 kilometers) from the impact, as well as white patches of ice around the crater, the most frozen water observed at such low latitudes, Posiolova said.

    Posiolova spotted the crater earlier this year after taking extra pictures of the region from orbit. The crater was missing from earlier photos, and after poring through the archives, she pinpointed the impact to late December. She remembered a large seismic event recorded by InSight around that time and with help from that team, matched the fresh hole to what was undoubtedly a meteoroid strike. The blast wave was clearly visible.

    Scientists also learned the lander and orbiter teamed up for an earlier meteoroid strike, more than double the distance of the December one and slightly smaller.

    “Everybody was just shocked and amazed. Another one? Yep,” she recalled.

    The seismic readings from the two impacts indicate a denser Martian crust beyond InSight’s location.

    “We still have a long way to go to understanding the interior structure and dynamics of Mars, which remain largely enigmatic,” said Doyeon Kim of ETH Zurich’s Institute of Geophysics in Switzerland, who was part of the research.

    Outside scientists said future landers from Europe and China will carry even more advanced seismometers. Future missions will “paint a clearer picture” of how Mars evolved, Yingjie Yang and Xiaofei Chen from China’s Southern University of Science and Technology in Shenzhen wrote in an accompanying editorial.

  • Saudi oil giant Aramco unveils $1.5B sustainability fund

    Saudi oil giant Aramco unveils $1.5B sustainability fund

    [ad_1]

    Saudi oil and gas company Aramco unveiled a $1.5 billion fund on Wednesday for sustainable investments, part of efforts to burnish the state-owned company’s green credentials in an announcement ahead of the U.N. climate conference next month in Egypt.

    Aramco CEO Amin Nasser said at an investment conference in Saudi Arabia that the fund will focus on “breakthrough technologies that are important and startups that will help us to address climate change.”

    Nasser billed the fund as one of the world’s biggest sustainability-focused venture capital funds and said it would invest globally and launch immediately. He spoke at Saudi Arabia’s Future Investment Initiative meeting, sometimes known as “Davos in the Desert,” a comparison to the World Economic Forum’s annual meeting of corporate bigwigs and world leaders in the Swiss Alps.

    Aramco is one of the largest corporate greenhouse gas emitters. Environmentalists have long accused oil and gas companies of using climate-friendly pledges to “greenwash” their polluting activities.

    One area Aramco’s fund will focus on is carbon capture and storage, which involves sucking heat-trapping carbon dioxide from factory smokestacks and storing it underground.

    Climate experts, however, warn the technology is risky, unproven and expensive and could be used to delay the phaseout of fossil fuels. Others say all untested solutions should be pursued given how little time there is left to meet U.N. emissions-cutting goals.

    Other investment themes the fund will target include greenhouse gas emissions, energy efficiency, nature-based climate solutions, digital sustainability, hydrogen, ammonia and synthetic fuels.

    Aramco has committed to reaching net zero operational emissions by 2050, but that only accounts for a fraction of the company’s total emissions. It does not include the carbon dioxide released by the burning of fossil fuels that the company produces.

    Oil companies have been using “green-sounding ‘net-zero by 2050’ pledges” to justify technological fixes that will allow them to “keep on digging up and selling oil and gas,” said Pascoe Sabido, a researcher specializing in the energy and climate sector at Corporate Europe Observatory, which investigates European Union business lobbying.

    “Aramco’s sustainability fund has nothing to with fighting climate change and everything to do with extending the life of its fossil fuel business,” he said.

    Saudi Crown Prince Mohammed bin Salman has been trying to diversify the economy away from oil revenue, though the government continues to rely heavily on crude exports.

    The U.N. climate conference, known as COP27, will hold negotiations aimed at limiting global temperature increases next month in the Red Sea resort town of Sharm el-Sheikh, Egypt.

  • Renters face charging dilemma as U.S. cities move toward EVs

    Renters face charging dilemma as U.S. cities move toward EVs

    [ad_1]

    PORTLAND, Ore. — Stephanie Terrell bought a used Nissan Leaf this fall and was excited to join the wave of drivers adopting electric vehicles to save on gas money and reduce her carbon footprint.

    But Terrell quickly encountered a bump in the road on her journey to clean driving: As a renter, she doesn’t have a private garage where she can power up overnight, and the public charging stations near her are often in use, with long wait times. On a recent day, the 23-year-old nearly ran out of power on the freeway because a public charging station she was counting on was busy.

    “It was really scary and I was really worried I wasn’t going to make it, but luckily I made it here. Now I have to wait a couple hours to even use it because I can’t go any further,” she said while waiting at another station where a half-dozen EV drivers circled the parking lot, waiting their turn. “I feel better about it than buying gas, but there are problems I didn’t really anticipate.”

    The great transition to electric vehicles is underway for single-family homeowners who can charge their cars at home, but for millions of renters like Terrell, access to charging remains a significant barrier. People who rent are also more likely to buy used EVs that have a lower range than the latest models, making reliable public charging even more critical for them.

    Now, cities from Portland to Los Angeles to New York City are trying to come up with innovative public charging solutions as drivers string power cords across sidewalks, stand up their own private charging stations on city right-of-ways and line up at public facilities.

    The Biden administration last month approved plans from all 50 states to roll out a network of high-speed chargers along interstate highways coast-to-coast using $5 billion in federal funding over the next five years. But states must wait to apply for an additional $2.5 billion in local grants to fill in charging gaps, including in low- and moderate-income areas of cities and in neighborhoods with limited private parking.

    “We have a really large challenge right now with making it easy for people to charge who live in apartments,” said Jeff Allen, executive director of Forth, a nonprofit that advocates for equity in electric vehicle ownership and charging access.

    “There’s a mental shift that cities have to make to understand that promoting electric cars is also part of their sustainable transportation strategy. Once they make that mental shift, there’s a whole bunch of very tangible things they can — and should — be doing.”

    The quickest place to charge is a fast charger, also known as DC Fast. Those charge a car in 20 to 45 minutes. But slower chargers which take several hours, known as Level 2, still outnumber DC fast chargers by nearly four to one, although their numbers are growing. Charging an electric vehicle on a standard residential outlet, or Level 1 charger, isn’t practical unless you drive little or can leave the car plugged in overnight, as many homeowners can.

    Nationwide, there are about 120,000 public charging ports featuring Level 2 charging or above, and nearly 1.5 million electric vehicles registered in the U.S. — a ratio of just over one charger per 12 cars nationally, according to the latest U.S. Department of Transportation data from December 2021. But those chargers are not spread out evenly: In Arizona, for example, the ratio of electric vehicles to charging ports is 18 to one and in California, which has about 39% of the nation’s EVs, there are 16 zero-emissions vehicles for every charging port.

    A briefing prepared for the U.S. Department of Energy last year by the Pacific Northwest National Laboratory forecasts a total of just under 19 million electric vehicles on the road by 2030, with a projected need for an extra 9.6 million charging stations to meet that demand.

    In Los Angeles, for example, nearly one-quarter of all new vehicles registered in July were plug-in electric vehicles. The city estimates in the next 20 years, it will have to expand its distribution capacity anywhere from 25% to 50%, with roughly two-thirds of the new power demand coming from electric vehicles, said Yamen Nanne, manager of Los Angeles Department of Water and Power’s transportation electrification program.

    Amid the boom, dense city neighborhoods are rapidly becoming pressure points in the patchy transition to electrification.

    In Los Angeles, the city has installed over 500 electric vehicle chargers — 450 on street lights and about 50 of them on power poles — to meet the demand and has a goal of adding 200 EV pole chargers per year, Nanne said. The chargers are strategically installed in areas where there are apartment complexes or near amenities, he said.

    The city currently has 18,000 commercial chargers — ones not in private homes — but only about 3,000 are publicly accessible and just 400 of those are DC Fast chargers, Nanne said. Demand is so high that “when we put a charger out there that’s publicly accessible, we don’t even have to advertise. People just see it and start using it,” he said.

    “We’re doing really good in terms of chargers that are going into workplaces but the publicly accessible ones is where there’s a lot of room to make up. Every city is struggling with that.”

    Similar initiatives to install pole-mounted chargers are in place or being considered in cities from New York City to Charlotte, N.C. to Kansas City, Missouri. The utility Seattle City Light is also in the early stages of a pilot project to install chargers in neighborhoods where people can’t charge at home.

    Mark Long, who lives in a floating home on Seattle’s Portage Bay, has leased or owned an EV since 2015 and charges at public stations — and sometimes charges on an outdoor outlet at a nearby office and pays them back for the cost.

    “We have a small loading area but we all just park on the street,” said Long, who hopes to get one of the utility’s chargers installed for his floating community. “I’ve certainly been in a few situations where I’m down to 15, 14, 12 miles and … whatever I had planned, I’m just suddenly focused on getting a charge.”

    Other cities, like Portland, are working to amend building codes for new construction to require electrified parking spaces for new apartment complexes and mixed-use development. A proposal being developed currently would require 50% of parking spaces in most new multi-family dwellings to have an electric conduit that could support future charging stations. In complexes with six spaces or fewer, all parking spaces would need to be pre-wired for EV charging.

    Policies that provide equal access to charging are critical because with tax incentives and the emergence of a robust used-EV market, zero-emissions cars are finally within financial reach for lower-income drivers, said Ingrid Fish, who is in charge of Portland’s transportation decarbonization program.

    “We’re hoping if we do our job right, these vehicles are going to become more and more accessible and affordable for people, especially those that have been pushed out of the central city” by rising rents and don’t have easy access to public transportation, Fish said.

    The initiatives mimic those that have already been deployed in other nations that are much further along in EV adoption.

    Worldwide, by 2030, more than 6 million public chargers will be needed to support EV adoption at a rate that keeps international emissions goals within reach, according to a recent study by the International Council on Clean Transportation. As of this year, the Netherlands and Norway have already installed enough public charging to satisfy 45% and 38% of that demand, respectively, while the U.S. has less than 10% of it in place currently, according to the study, which looked at electrification in 17 nations and government entities that account for more than half of the world’s car sales.

    Some European cities are far ahead of even the most electric-savvy U.S. cities. London, for example, has 4,000 public chargers on street lights. That’s much cheaper — just a third the cost of wiring a charging station into the sidewalk, said Vishant Kothari, manager of the electric mobility team at the World Resources Institute.

    But London and Los Angeles have an advantage over many U.S. cities: Their street lights operate on 240 volts, better for EV charging. Most American city street lights operate on 120 volts, which takes hours to charge a vehicle, said Kothari, who co-authored a study on the potential for pole-mounted charging in U.S. cities.

    That means cities considering pole-mounted charging must also come up with other solutions, from zoning changes to making charging accessible in apartment complex parking lots to policies that encourage workplace fast-charging.

    There also “needs to be a will from the city, the utilities — the policies need to be in place for curbside accessibility,” he said. “So there is quite a bit of complication.”

    Changes can’t come fast enough for renters who already own electric vehicles and are struggling to charge them.

    Rebecca DeWhitt rents a house but isn’t allowed to use the garage. For several years, she and her partner strung a standard extension cord 40 feet (12 meters) from an outlet near the home’s front door, across their lawn, down a grassy knoll and across a public sidewalk to reach their Nissan Leaf on the street.

    They upgraded to a thicker extension cord and began parking in the driveway — also a violation of their rental contract — when their first cord charred under the EV load. They’re still using their home outlet and it takes up to two days to fully charge their new Hyundai Kona. As of now, their best alternative for a full charge is a nearby grocery store which can mean a long wait for one of two fast-charging stations to open up.

    “It’s inconvenient,” she said. “And if we didn’t value having an electric vehicle so much, we wouldn’t put up with the pain of it.”

    Russian cosmonaut runs over colleague after space return

    [ad_1]

    MOSCOW — After three missions in space, Russian cosmonaut Oleg Artemyev ran into difficulty on Earth when he drove over a colleague on a dark road outside Moscow less than three weeks after returning from his latest orbiting mission.

    Russia’s state space corporation Roscosmos said Artemyev didn’t see an employee of the Star City cosmonaut training center who was crossing the road in the dark late Monday.

    It said in a statement Tuesday that Artemyev immediately provided first aid assistance to the victim, Anatoly Uronov, who was hospitalized with several fractures. Roscosmos emphasized that Artemyev was sober and immediately called police and an ambulance.

    On Sept. 29, the 51-year-old Artemyev returned from his third mission to the International Space Station, which brought his total time spent in orbit to 561 days.

    Smartphone maker Foxconn unveils EV for Taiwan brand Yulon

    [ad_1]

    TAIPEI, Taiwan — The company that assembles smartphones for Apple Inc. and other global brands unveiled an electric SUV on Tuesday that will be produced for a Taiwanese automaker under a similar contract model.

    Foxconn Technology Group said the SUV will be sold by Yulon Motor as the Luxgen n7 starting next year. It said the five-seat vehicle should be able to travel 700 kilometers (440 miles) on one charge. No price was announced.

    Foxconn, also known as Hon Hai Precision Industry Co., plans to produce electric cars and buses for brands in China, North America, Europe and other markets. It said clients can modify their appearance and features.

    The venture adds to a crowded global market with electrics offered by almost every established automaker and dozens of ambitious startups.

    “Hon Hai will certainly redefine the EV industry,” company founder Terry Gou said in a statement.

    Foxconn, headquartered in New Taipei City, Taiwan, is the world’s biggest contract assembler of smartphones and other consumer electronics.

    Yulon, founded in the 1940s, assembles vehicles for Nissan Motor Co. and other automakers. The company launched its own brand, Luxgen, in 2009.

    The Luxgen n7 is one of five proposed models for potential customers.

    On Tuesday, Foxconn also displayed a five-seat crossover, the Model B, and a five-seat double-cab pickup truck, the Model V.

    The company previously announced plans for a sedan developed with Italian design house Pininfarina and an electric bus, the Model T.

  • General Motors broadens electric goals with new division

    General Motors broadens electric goals with new division

    [ad_1]

    General Motors, which plans to go almost entirely electric by 2035, is creating a new energy division that will produce chargers for electric vehicles, as well as solar panels and other energy-related technology for homes and businesses.

    The company said Tuesday that the unit, called GM Energy, will create systems for households and commercial customers that link electric vehicles to power storage and generation. The division should have the capacity to sell energy from electric vehicle and stationary storage batteries back to utilities during peak periods of energy usage.

    “GM Energy has the opportunity to help deliver sustainable energy products and services that can help mitigate the effect of power outages and provide customers with resilient and cost-effective energy management,” Travis Hester, vice president of GM EV Growth Operations, said in a statement.

    GM’s Energy Services Cloud will include data and energy management tools and let customers manage their energy usage.

    Ultium Charge 360, which includes several charging station networks and software, will expand its portfolio of integrated public charging networks, integrated mobile apps, and additional product and service offerings over time as part of the division.

    GM said it also has partnerships with several companies, including solar technology and energy services provider SunPower. In the deal with SunPower, the two companies will develop and offer customers a home energy system that includes integrated electric vehicle and battery solutions, solar panels and home energy storage. The system will be available at the same time as the retail launch of the 2024 Chevrolet Silverado EV, which is expected to start production in the fall 2023.

    There’s also a pilot project with Pacific Gas and Electric to allow residential customers to use their compatible electric vehicles with a bi-directional charger as backup power for essential home needs during power outages. After initial lab tests, the companies anticipate expanding the offer to some residential customers within PG&E’s service area. This is expected to begin next year.
