Looks like you have to you’ll have to buy a bit more juice your next grocery run, some for you and some for your kids’ toys.  The Tomy Ene Pocket RC Car is here and it runs on juice or soda and doesn’t rely on the conventional ackleline  batteries.

What you do is fill up the little car with juice/soda just like you do with gasoline with your regular car.   The car has a bio battery which breaks down the sugars from the liquids  to generate electricity.

The bio battery technology was a brain child of Sony (juice powered Televisions maybe?)  and can output 50 mw of power.    The juice/soda for the  car might be a bit more expensive than using a battery but it’s friendlier on the landfills without the hassle of battery disposal.
