Cars that run on compressed air.
Taken from the website:
Compressed air is an energy vector that can be used, in a viable way, to transport both people and goods.The main goal of Air Car Factories is to develop and manufacture a vehicle driven by a compressed air engine with a level of performance that will respond to the actual needs of today’s market. With this aim we have drawn up a full agenda and an R&D plan of action for production start up.

They also have another model which runs on compressed air and electricity. Either way, it’s a cool concept that breaks the link between you and big oil.
