Liquid Metal Battery raises $15M in series B financing

Liquid Metal Battery, an MIT spinoff backed by Bill Gates, has secured an additional $15 million in series B financing in a funding round led by Khosla Ventures, the company announced today.

The Cambridge, Mass.-based company, which aims to build a cheap battery for bulk storage of wind and solar power, also announced that Andrew Chung, a Khosla Ventures partner, would join the board.

"Our Liquid Metal Battery technology is tremendously exciting because it has the potential to dramatically change the electric power system everywhere," Liquid Metal Battery CEO Phil Giudice said in a statement announcing the new funding. "more

The real prize for GM's EcoCar2 challenge? A job offer

In each of the three years of EcoCar2 Challenge, General Motors will give away approximately $100,000 in prizes to the students participating in the alternative fuels vehicle competition. But for some students, the real prize will be a steady paycheck.

Headliners GM and the Department of Energy, along with 25 suppliers, sponsor EcoCar2, a three-year alternative fuels vehicle competition, as a way to encourage college students to enter the automotive industry. It provides a chance for young engineers to apply the theoretical education they gain in the classroom in the lab, giving them an advantage when it comes to more

Mitsubishi builds i-Miev Evo electric car for Pikes Peak

Mitsubishi Evos, performance-modified versions of the Lancer model, became legendary on the offroad rally circuit for their exceptional handling. Now Mitsubishi takes the Evo designation into the future with the first i-Miev Evolution, a performance version of its pod-like i-Miev electric city car.

Mitsubishi built the i-Miev Evo for the annual Pikes Peak Hill Climb, a race featuring 156 turns over 12.42 miles with a 4,700 foot ascent. The company says it started with a stock i-Miev, but the specs show heavy modification. Along with a completely new, carbon fiber body, the i-Miev Evo gets three 80 kilowatt more

A Mercedes-Benz hydrogen SUV or sedan in the works

The hydrogen highway is still unrealized, but when it comes, Mercedes-Benz is planning a lineup of fuel cell vehicles to ride it.

The auto manufacturer plans to release two new hydrogen vehicles in the next few years, according to an Automotive News article. Mercedes-Benz currently leases an F-Cell hydrogen-fueled vehicle based on the compact B-Class model in a handful of states. The F-Cell has a 240-mile driving range, emits only water vapor when driven, and can be leased for $849 per month.

To date, the company has leased approximately 35 F-Cells in Southern California where the lion's share of hydrogen fueling stations are being built, more

Fisker Atlantic plans, specs leaked

If you're in the market for a luxury plug-in hybrid sedan, start saving up the $50,000 to $60,000 you'll need to buy the Fisker Atlantic sedan. And you'll have plenty of time -- don't expect to see the car in the showrooms for another couple of years.

Details of Fisker's second plug-in hybrid were leaked to InsideEvs.com. The Fisker Atlantic, formerly known as Project Nina, is the startup's follow-up to its $100,000 Karma plug-in hybrid sports car. The Atlantic is a smaller, more affordable luxury coupe that will be equipped more

Tata commercializing an air-powered car

An air-powered car may not be a pipe dream after all. Tata Motors announced last week that it is beginning phase two of development to bring this technology to market.

Lightweight cars powered only by air have made the rounds on the auto show circuit for the past two years. But since 2007, the Indian automotive manufacturer has been working with Motor Development International, which is pioneering this technology, to make this highly conceptual propulsion system a reality.

Tata has successfully demonstrated the compressed air engine concept in two of its vehicles, and will enter phase two of the partnership more

Hitch a ride through Google's cloud

Your Gmail box lives somewhere in the jumble of servers, cables, and hard drives known as the "cloud" but it often migrates in search of the ideal location.

Google today released an animation that answers the question: what happens when I press send on Gmail? The company created the interactive feature called The Story of Send to highlight the security and relatively low energy footprint of its data centers. The graphics repeat Google's estimate that its data centers use 50 percent less energy than a typical data center and 30 percent of their data center energy is supplied from more

Step on it: Virus could lead to motion-powered gadgets

Scientists are genetically engineering viruses in the pursuit of better battery life, perhaps leading to smartphones charged from the motion of walking.

The Department of Energy's Lawrence Berkeley National Laboratory yesterday described a microelectronic device that uses a benign virus to build up electric charge from movement.

Its first prototype was able to display the No. 1 on an LCD display when a person pressed a postage-stamp size button.

That amount of current isn't useful enough to charge common electronics, such as a music player or phone. But the researchers' novel approach to harvesting energy from motion shows more

Got a deck? Solar panels now a plug-in appliance

It's a green-energy geek's dream do-it-yourself project: attach a few solar panels to your deck and watch your electric bills go down. Now one company is selling such a product.

SpinRay Energy has developed a system that lets consumers install up to five solar panels on their decks and plug them into an outdoor power outlet. People can install one panel at a time, and get up to 1,000 watts of power with five installed.

The main electrical components of the system have the UL safety certification, including the solar panel and the microinverter, which converts direct more

Get smart: Charge your phone while walking in this shoe

Love walking and texting? Still haven't done a faceplant on a streetlight? Well, this sneaker from Kenya can power your phone so you'll never have to look up from that screen again.

Inventor Anthony Mutua, 24, has been showing off his recharging sneaker at the first-ever Kenyan Science Technology and Innovation Week, held in Nairobi. It's another way of using your body's own energy to fuel electronics.

The shoe apparently has a very thin "crystal chip," perhaps a piezoelectric device, that generates power when the sole bends. It can charge phones via a long cable to a pocket while the user walks, or store power for later charging.
