Hasta La Gadget!

At January’s Detroit Auto Show, Mercedes-Benz eagerly showed off its hydrogen-powered F-Cell car, vowing to prove the viability of fuel-cell vehicles by driving three of them around the world. And now, 18,641 total miles later, it’s completed that circumnavigation, arriving safely home at the company’s Stuttgart headquarters. Does this prove fuel-cells are ready for prime time? Well, the trip took 70 driving days to cover four continents, and the vehicles’ range topped out at just over 400 miles — in Kazahkstan. But M-B admits there are only 200 refilling stations worldwide; in most cases the F-Cells had to rely on a tag-along mobile refueling unit. The company hopes its demonstration will spur development in a refilling-station infrastructure: having a fuel-cell car you can’t easily refuel must feel like owning a flying DeLorean in 1885. To get the full breakdown, see the Mercedes-Benz PR after the break.

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

Green transportation took off for the stars this week as Inhabitat reported that the European Space Agency has approved of a new hydrogen-powered “Skylon” space plane, and we spotted a hot Star Wars-inspired electric chopper that wouldn’t look out of place on the Death Star. We also learned that NASA plans to rejoin the space race with a new MPCV craft fit for deep space flights, while here on Earth we saw GE harness the power of the sun to charge Volt EVs before they hit dealerships.

Speaking of solar power, Japan unveiled plans to construct 10 new solar power plants in the wake of the Fukushima Nuclear Crisis, while Switzerland announced that it will completely phase out the use of nuclear power. We also showcased a stunning chandelier made from 500 fluttering photovoltaic butterflies, and we saw Nevada kick-start construction on the US’ first molten salt solar plant, which will generate energy long after the sun has set.

We also brought you several incredible feats of architecture this week, from a restaurant made from a recycled Soviet airplane in Zurich to an innovative cocoon-like building made from sugarcane that recently won an AIA competition. We also showed how Plantlab is making vertical urban farms a reality, and we spotted a sky-high proposal for an energy-generating city on stilts that would hover over Manhattan. Finally, this week we rounded up some of our favorite eco apps and services that can help you green your consumption.

Photovoltaics suffer from gross inefficiency, despite incremental improvements in their power producing capabilities. According to research by a team led by a University of Missouri professor, however, newly developed nantenna-equipped solar sheets can reap more than 90 percent of the sun’s bounty — which is more than double the efficiency of existing solar technologies. Apparently, some “special high-speed electrical circuitry” is the secret sauce behind the solar breakthrough. Of course, the flexible film is currently a flight of fancy and won’t be generating juice for the public anytime soon. The professor and his pals still need capital for commercialization, but they believe a product will be ready within five years. Take your time, guys, it’s not like global warming’s getting worse.

Oh, how the winds of fortune can swirl. Just a few weeks after finally selling its first LiFe electric car to a happy couple in Atlanta, Wheego appears to have suddenly fallen on hard financial times. Very hard times. Speaking to Automotive News, CEO Mike McQuary claimed that his startup’s coffers are bare enough to jeopardize future production of Wheego’s flagship, battery-powered two-seater:

“My constraint is primarily capital. We’ll be living hand-to-mouth as we try to get the first cars built. The next 200 will creep out as we raise money.”

McQuary didn’t say how far behind schedule Wheego is at the moment, but part of the problem seems to be finding enough money to buy parts for its $32,995, 100-mile range EVs. The company’s plant in California was supposed to produce 200 vehicles a month starting in January, in the hopes of eventually churning out 60,000 a year. Those plans, however, were soon derailed, due to unexpectedly delayed approval from the National Highway Transportation Safety Administration — a setback that also hurt the company’s capital raising campaigns. The company is hoping to raise some $15 million with the help of a VC firm in Connecticut, but until it does, Wheego may not be going anywhere.

Wheego needs more cash to produce LiFe EVs, ‘living hand-to-mouth’ for now originally appeared on Engadget on Tue, 03 May 2011 09:19:00 EDT. Please see our terms for use of feeds.

Wheego has, at long last, let its first $32,995, 100-mile range LiFe electric two-seater loose on the public, and added another cute little electric car to the US EV collective. By either stroke-of-luck or sheer coincidence (no way is it intentional), the first of the breed was delivered today, otherwise known as Earth Day, to a couple of lucky owners in the ATL. Good to see Dixieland drivers (who often prefer something with a lift kit and Super Swampers to fuel-efficient subcompacts) bringing cleaner motoring to the derrrty South.
