The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us.
It was also another big week for solar power as technological advances produced photovoltaic cells that are smaller, more efficient, and more versatile in their applications. IBM unveiled a new breed of thin-film cells that are 40% more efficient than previous prototypes, while the University of Michigan announced the world's smallest solar-powered sensor, which measure a scant 9 cubic millimeters.
Finally, we were flat-out wowed by Porsche's latest supercar - a 911 hybrid that will be taking on the competition at the 24 hour Nürburgring race this May. The vehicle is based on the tried-and-true 911 platform but features some race-ready tricks under the hood: front wheel hybrid drive and a kinetic energy recovery system that stores braking energy in a flywheel that delivers a 160hp boost of speed with the press of a button.
