crystalline honeycomb skyscrapers for Abu Dhabi and San Francisco unfurled plans for a sail-shaped solar stadium for the America's Cup yacht race. We also took an exclusive look inside a high-tech solar home that actually produces more energy than it consumes, and spotted a new technology that can transform any home's electrical wiring into an information-transmitting antenna.
We also showcased some of the world's most efficient vehicles as the winners of the $10 million Automotive X-Prize were announced, and we were excited to hear that the first factory-built Fisker Karma supercar will be rolling up to the Paris Auto Show next month. Finally, we peek inside Jay Leno's envy-inducing green garage in this week's episode of Green Overdrive.
In other news, MIT made waves on the renewable energy front as they revealed a new "solar funnel" technology that could increase the efficiency of photovoltaic cells 100 times. We also took a first look at Eddy GT's new streamlined city-friendly wind turbine, and we saw Tesla batteries jump-start residential solar systems by storing excess energy.
