One car's latest innovation- using 'air' as 'fuel'

Aside from high gas prices many people buy electric cars to be a little greener but one car that runs on nothing but air could be the greenest of them all.

The car doesn't produce any emissions since it isn't burning anything. It runs by cooling air to a liquid and then heating the liquid into a gas that powers the engine.

But don't expect to get too far in it very fast, it tops out at 30 mph.

This model is just an early prototype. An engine manufacturing company is already working on a more polished package.
