It was love at first drive for Chris Schneider and his Honda Clarity.“This is the most rewarding automotive experience I’ve ever had and I’ve driven lots of different vehicles with all kinds of technologies,” the 61-year-old said on a recent Sunday morning while fueling up.But Schneider was a solitary figure at the pump because his car does not run on gasoline and it’s not an electric vehicle (EV) in need of a charge.It’s a hydrogen fuel cell vehicle and Schneider is filling up at the only station in all of San Diego County that carries the fuel to keep his car running. It’s located on the north end of a Shell station at the corner of Interstate 5 and Carmel Valley Road. Since the market for hydrogen-powered cars is in its infancy, there are only about 3,000 fuel cell vehicles on the road.And since there are so few cars, there aren’t many fueling stations for them — 31 and counting so far across the state.The stations that have been … [Read more...] about San Diego waits to drive into the hydrogen fuel cell fast lane

Ars makes every effort to cover its own travel costs. To attend Nikola's conference, we covered the flight out to Scottsdale, Arizona, but Nikola covered one night in a nearby hotel. SCOTTSDALE, Arizona—The Nikola Motor Company wants to reinvent trucking by replacing diesel heavy-duty trucks with hydrogen fuel cell trucks. But hydrogen skeptics are numerous, and not without good reason. Although hydrogen fuel cell vehicles are quiet, emissions-free (with the exception of water) during operation, and relatively fast-charging compared to battery electric vehicles, they have a host of other problems. Further ReadingNikola Motor Company shows off two real trucks and… a new jet ski?First, hydrogen is hard to store, and it must be cooled and compressed. It's also hard to transport. Additionally, H2 is not a green fuel in the US, for the most part. Generally, natural gas (CH4) is reformed to create H2 in ways that still cause carbon emissions. There is a way to create … [Read more...] about The hydrogen fuel strategy behind Nikola’s truck dream
Space station astronauts Anne McClain and Nick Hague suited up for a planned six-and-a-half-hour spacewalk Friday, the first of two needed to install a second set of more powerful lithium-ion batteries in the International Space Station's solar power system. Floating in the station's Quest airlock, the astronauts were expected switch their spacesuits to battery power around 8 a.m. EDT, officially kicking off the 214th spacewalk since ISS assembly began in 1998.For identification, McClain, call sign EV-1, will wear a suit with red stripes and use helmet camera No. 20. Hague, EV-2, will wear an unmarked suit and using helmet camera 17.The goal of the outing is to finish a job already started by flight controllers using the station's robot arm: replacing six massive nickel-hydrogen batteries on the port, or left, side of the station's power truss with three more powerful 300-pound lithium-ion batteries.McClain and Hague will install adapter plates needed to tie the new batteries into the … [Read more...] about Two space station astronauts to tackle challenging spacewalk
Watching the Hyundai pull into the parking spot, I cringe a bit with the stress that strikes when I feel like I’m holding other people up. The car is wiggling backward and forward, backward and forward, trying to fit into the dead center of the spot, and another driver is stuck, waiting to get by in the tight garage. Once the Hyundai is finally parked, the waiting driver pulls up and stops, window down and eyes wide open. And she’s not annoyed. “Did that thing just park itself?” she asks. I tell her it did, though I have to stand nearby, holding down a button on the key. “What in the world?” she says. “Now I’ve seen everything.” The car in question is the Nexo, Hyundai’s newest midsize SUV, with room for five and a week’s worth of groceries. And while the self-parking capability is its most noticeable, maybe marquee, feature, that’s not what makes the Nexo interesting, nor does it explain the blood-draining $58,300 … [Read more...] about New Hydrogen-Powered Hyundai: a Gas to Drive, a Pain to Fuel
Over 19,000 known asteroids, carrying an almost inconceivable wealth of resources, are within our reach as they orbit the Sun. They’re packed with elements like platinum, gold, palladium, and silver — untouched riches locked safely inside celestial treasure chests. Ryugu, a half-mile wide asteroid that poses a potential risk to Earth due to the proximity of its orbit, is estimated to contain $83 billion worth of nickel, iron, cobalt, and nitrogen. The larger but less threatening Anteros is thought to have some $5,570 billion worth of magnesium silicate, aluminum, and iron beneath its surface. By refueling its steam propulsion reserves as it goes, WINE is designed for near-indefinite exploration. A burgeoning industry of aerospace veterans and newcomers aims to mine these asteroids like space prospectors. Some want to extract elements that are valuable on Earth before transporting them back to the planet. Others have their sights set on resources that will be vital to … [Read more...] about Does a steam-powered spacecraft hold the key to exploring the solar system?
