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.
Speaking of hot asphalt, this week the ultra-efficient Alerion race car blazed a trail at the Shell Eco-Marathon, clocking in an incredible 2,564.8 miles per gallon. Meanwhile, Fisker announced that its sexy electric Karma sedan will hit the road this summer, and we were surprised to hear that Marcelo da Luz was forced to pull his solar-powered X of 1 car across Ontario due to road regulations. The New York Auto Show also kicked off with a blast this week as Lexus unveiled its next-gen LF-Gh concept hybrid and Porsche rolled out a 911 GTR 3 in a Facebook colorway that got a lot of "likes".
Finally, we looked at several futuristic example of wearable technology this week including a pair of RoboCop-like glasses that are capable of scanning 400 faces per second at public events. We also brought you a brilliant LED backpack that lets cyclists send signals to drivers, a pollution-detecting t-shirt, and a clock that tells time by knitting a new scarf every year.
