Japanese inventor Hikoshichi Takahashi is patenting a wind-powered generator that sits on the roof of a car. The device has either funnels or tubes, or both, which channel fast-moving air into a generator to produce electric power for the car. Excess power can be stored in the car's battery. Sadly, Takahashi seems to think that he can defy the laws of physics and get something for nothing: the energy generated will come at the cost of increased drag caused by the roof-mounted generator.
