Air Powered Car (held together by… glue)

The first product, the CityCAT, reaches a top speed of 68mph and can go about 125 miles without refilling the carbon fiber compressed air chambers. The CityCAT’s made of lightweight, glued-together fiberglass and foam, and the engine is made up almost entirely of aluminum. The air tanks hold 52 gallons of compressed air at 4,351psi, and refueling can take only three minutes at your local gas station. You can also plug in the vehicle for about four hours, so the on-board compressor can fill the tanks at a cost of about $2.
