New Car that runs on Air

An air-powered car? It may be available sooner than you think at a price tag that will hardly be a budget buster. The vehicle may not run like a speed racer on back road highways, but developer Zero Pollution Motors is betting consumers will be willing to fork over $20,000 for a vehicle that can motor around all day on nothing but air and a splash of salad oil, alcohol or possibly a pint of gasoline. A new carmaker has a plan for cheap, environmentally friendly cars to be built.

The expertise needed to build a compressed air car, or CAV, is not rocket science, either. Years-old, off-the-shelf technology uses compressed air to drive old-fashioned car engine pistons instead of combusting gas or diesel fuel to create a burst of air to do the same thing. Indian carmaker Tata has no qualms about the technology. It has already bought the rights to make the car for the huge Indian market. The air car can tool along at a top speed of 35 mph for some 60 miles or so on a tank of compressed air, a sufficient distance for 80% of consumers to commute to work and back and complete daily chores.

On highways, the CAV can cruise at interstate speeds for nearly 800 miles with a small motor that compresses outside air to keep the tank filled. The motor isn't finicky about fuel. It will burn gasoline or diesel as well as biodiesel, ethanol or vegetable oil. This car leaves the highest-mpg vehicles you can buy right now in the dust. Even if it used only regular gasoline, the air car would average 106 mpg, more than double today's fuel sipping champ, the Toyota Prius. The air tank also can be refilled when it's not in use by being plugged into a wall socket and recharged with electricity as the motor compresses air. Automakers aren't quite ready yet to gear up huge assembly line operations churning out air cars or set up glitzy dealer showrooms where you can ooh and aah over the color or style. But the vehicles will be built in factories that will make up to 8,000 vehicles a year, likely starting in 2011, and be sold directly to consumers.
