Pretty cool air powered car. Says it cost a pound ($1.75 US) to power the car for 8 hours/124 miles. Enjoy.
"The MDI car can reach a speed of 68 mph and has a road coverage of roughly 124 miles -some 8 hours of travel- which is more than double the road coverage of an electric car. When recharging the tank, the car needs to be connected to the mains (220V) for 3 to 4 hours or attached to an air pump in a petrol station for only 2 minutes."
"90m3 of compressed air is stored in fibre tanks. The expansion of this air pushes the pistons and creates movement. The atmospheric temperature is used to re-heat the engine and increase the road coverage. The air conditioning system makes use of the expelled cold air. Due to the absence of combustion and the fact there is no pollution, the oil change is only necessary every 31.000 miles.
At the moment, four models have been made: a car, a taxi (5 passengers), a Pick-Up truck and a van. The final selling price will be approximately 5.500 pounds."
