Comments on: An Air Car You Could See in 2009: ZPM's 106 MPG Compressed-Air Hybrid http://gas2.org/2008/07/15/an-air-car-you-could-see-in-2009-zpms-106-mpg-compressed-air-hybrid/ What is the future of fuel? What's new? What's next? Since 2007, Gas 2 has covered a rapidly changing world coming to terms with its oil addiction.

I am English but live in the South of Spain so I would like to experiment on the above using Solar Energy. One could probably redesign or modify the old Wankel Rotary Engine....?

Also, why not a small wind mill at home to drive a air compressor,(even an old lawn mower engine may be converted over to air compress,)attached of course to the windmill This would give you "free air" for the A-car.

One might think there is a concerted effort to squash information. To those who insist these cars are not energy efficient, might I refer you back to the information presented. Car recompresses in two minutes at a gas station. Last I knew that runs about a quarter. At home, using a electric compressor, about 4 hours ...$2. Range of 1 tank of air + 8 gal gas to recompress as you drive...848 miles. Without the gas assist all that comes out of the tailpipe is water. AND, the air tank is made of carbon fiber that splits upon impact = no explosion, only a whoosh of air. Frankly, I can't think of a cleaner vehicle.

We don't carry the pollution tailpipe in to the city or our garage and let the professionals handle the pollution at power plant. For power plant they can use other sources of energy.

When the car is charging(3-4 hours) an electric motor is powering a multistage piston reciprocating air compressor that has liquid intercooling between stages and around the cylinders. The heat of compression would be stored in an insulated tank filled with paraffin or a eutectic salt solution. The energy density/kilogram of this 'thermal battery' could match or exceed that of electric batteries, even though it could be bulkier. Even a modified 40 gallon hot water could be used for this. 120 pounds of water heated from 50F to 210F degrees contains the energy of 1 pound of gasoline. So 40 gallons of very hot water contain about 1/2 gallon of gasoline energy. The compressed air tank(s) would also be contained within an insulated heat storage tank The compressor would also be insulated, to keep heat loss to a minimum. When the car is running the compressor becomes a multistage expansion engine-similar to triple expansion steam engines-with interheating between stages using the stored heat of compression. Now comes the best part. The waste heat from a small gasoline engine can be used to boost the reheating process increasing the power and range of this car. This could also be a partial electric car with a few batteries and a small generator powered by the gas engine powering the compressor motor as an electric drive motor. This can reduce expensive battery usage, not use a transmission, and the compressor/expansion engine can be made of aluminum to reduce weight. This could work as a plug in hybrid, let me explain.
