SAIC & GM have teamed up to create The YeZ concept car. This car would run on solar and wind energy. Nothing we haven't heard before, right? Well, the YeZ manages to stand out by converting CO2 to oxygen.

Captain Planet called--he wants his car back. The YeZ has solar turbines on the roof and wind turbines in the wheels. This car looks a little femme for me, but if it helps to clear our air, I'm all for it.
