on How Air Cars Work

Compressed air is forced into the converter pushing the pistons as a conventional petro converter would push pistons using tiny explosions. Gasoline, Deisel and other petrochemicals are not used at all to run these engines. This engine would save money for consumers on energy costs and would greatly reduce reliance on fuels from foreign countries. This is a wonderful "green" idea.

Another alternative to gasoline and other petro chemicals is water. See my article on how to turn water into fuel for your current car with a converter added under the hood.
