Freevolt generates power from thin air
What you see above may look like an unremarkable slice of electronics, but it can theoretically power a low-energy device forever, and for free. If that sounds like a big deal, well... that's because it is. Drayson Technologies today announced Freevolt, a system that harvests energy from radio frequency (RF) signals bouncing around in the ether and turns it into usable, "perpetual power." Drayson isn't exactly a household name, but the research and development company has a particular interest in energy, especially where all-electric racing is concerned. And now it's developed the first commercial technology that literally creates electricity out of thin air.
Qualcomm's Halo wireless charging tech headed to Formula E, safety cars get first dibs
Ahead of the Frankfurt Motor Show this week, Qualcomm has come out to announce that it'll be bringing its Halo wireless charging technology to the first-ever Formula E electric vehicle race next year. But before y'all get too excited, only the safety cars will be equipped with Halo for the first season, which goes from September 2014 to June 2015 in London, Rome, Berlin, Beijing, Kuala Lumpur, Los Angeles and many more places. As with these safety cars plus trial vehicles from London taxi firm Addison Lee, the current-gen Halo requires electric vehicles to stay still on large charging pads, which isn't ideal for racing cars. That said, Qualcomm CMO Anand Chandrasekher told us that his folks are already looking into bringing dynamic charging to racing cars starting in the second season. In other words, these battery-powered vehicles will eventually be able to recharge while still running on the race track!
Inhabitat's Week in Green: 300 passenger bus, babyloid robot and a jellyfish-esque LED chandelier
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. Sustainable transportation broke new boundaries by land and sea this week as Inhabitat reported that China launched the first 300 passenger bus and the world's largest solar ship closed in on completing its first trip around the globe. We also saw Drayson unveil a turbocharged 850 horsepower all-electric supercar while Mercedes announced plans to bring its B-Class E-Cell electric Vehicle to the US next year. Speaking of hot upcoming cars, this week we brought you a video showcasing 5 of the most exciting eco cars from the 2012 Detroit Auto Show and we shared 7 new hybrid and electric vehicles that you'll be able to purchase this year.The world of renewable energy also heated up this week as scientists hatched a plan to harness volcano power by pouring millions of gallons of water into a dormant crater and President Obama rejected TransCanada's plans for the Keystone Xl pipeline. Meanwhile Philips unveiled a transparent solar-powered OLED car sunroof that charges during the day and lights up at night, and we took a look inside Switzerland's Berghotel Muottas - the first hotel in the Alps that generates more energy than it consumes. Clean energy technology also dived into the deep blue sea as Ireland's massive SeaGen tidal turbine received environmental approval, researchers found a way to turn seaweed into biofuel using a human stomach microbe, and a Nobel laureate developed the world's cheapest and most effective CO2 sponge.In other news, this week we brought you the most freshest new green gadgets - from a tree trunk turntable that plays wood rings like records to a stunning jellyfish-esque LED chandelier and a cuddly Babyloid robot designed to comfort senior citizens. We also showcased the world's smallest greeting card (300 micro-meters wide!), a massive 300 lb stormtrooper cake, and five educational and arty apps for creative kids. Finally, we rounded up the hottest news in eco fashion - including the world's largest garment made from golden spider silk and an awesome set of bow ties made from recycled LEGO bricks.
