A Car that Works Like a Plant

The YeZ concept car, unveiled by the Shanghai Automotive Industry Corp. at the Shanghai Expo 2010, converts carbon dioxide and releases oxygen.

According to CNET:

YeZ works its magic of photoelectric conversion with the help of state-of-the-art solar panels on the roof, wind power conversion via small wind turbines in the wheels, and carbon dioxide absorption and conversion through the bodywork. This last bit is made of a metal-organic framework that can apparently absorb carbon dioxide and water molecules from the air. Through the series of chemical reactions, energy is generated, and it's then stored in the car's lithium ion batteries.
