The question, as WorldChanging's Adam Stein says, is whether it works well enough. A company called Zero Pollution Motors claims that its new, improved model will go 848 miles on one tank of compressed air.
"As an energy storage mechanism, compressed air has certain built-in advantages over lithium ion batteries. An air tank is far cheaper than a battery, quicker to charge, and easy to maintain.
On the flip side, the air-powered car suffers from the same problems that have doomed so many other attempts to move beyond the internal combustion engine: limited range and a lack of refueling infrastructure. Zero Pollution Motors claims to have addressed the range issue with the addition of a small fuel-powered heater, which boosts the efficiency of the air engine. Although the heater gives the lie to the "zero pollution" claim, such a system still represents a considerable efficiency improvement over conventional gasoline-driven cars."
