Car companies are always trying to develop the best ways to save on fuel. Well, Ethan Tucker and Pat Boone of Zero Pollution Motors, the U.S. licensee for Motor Development International, might have the next big thing…the AIRPod. The AIRPod runs on cold air compressed in tanks to 300 times atmospheric pressure. AIRPod says the car can be refilled from a compressed-air station in about three minutes for less than $3. With the car weighing in at just over 600 pounds, a top speed reaching about 50 mph and an 80-mile range, the AIRPod would seem to make for the perfect city car.
