With the high price of gas and the fear that the world’s supply of oil is in decline, some automakers are looking to alternatives to power the next generation of automobiles including some outside-the-box ideas.

At the Geneva Motor Show this week French company MDI unveiled a car that it says can run on something that is in great abundance in the world – air.

The company says that the car, dubbed the AirPod, can travel for 137 miles on a 46-gallon tank of compressed air, according to the International Herald Tribune.

In order to refill the vehicles, the news provider says drivers can plug the car into any standard outlet for eight hours to recharge the tank or visit “air stations” which will fill the chamber in two minutes.

The three-wheeled car is expected to hit roads later this year for about $7,500.

Also unveiled at the Geneva Motor Show was Toyota‘s next generation of its gas/electric hybrid, the Prius. The company says the 2010 model will get an EPA rated 50 miles per gallon, making it the most fuel efficient production car in the U.S.
