Air cars - a surprisingly well-developed technology
Zero Pollution Motors
Well, not quite zero pollution, but 106 mpg (US) is impressive.
To drive the world’s cleanest car is no longer wishful thinking. The Compressed Air Vehicle is the first affordable and accessible clean car. It brings us our dream: to drive pollution-free and free of fuel dependency.
At Lower Speeds: Since the Compressed Air Vehicle is running exclusively on compressed air, it emits only air - zero pollution. The air expelled from the tail pipe is actually cleaner than the air used to fill the tank. This is because before compression, the air is run through carbon filters to eliminate dirt, dust, humidity, and other urban air impurities that could hamper the engine’s performance.
At Higher Speeds: At speeds over 35mph the Compressed Air Vehicle uses small amounts of fuel–either gasoline, propane, ethanol or bio fuels–to heat air inside a heating chamber as it enters the engine. This process produces emissions of only 0.141lbs of CO2 per mile. That is up to 4 times less than the average vehicle and more than two times less than the cleanest vehicle available today.
