GOOD: No exhaust, except for the driver who is exhausted pulling into air stations every couple miles... The limited range is just "air full"... (sorry!)

BAD: Limited range per "pump fill", dangerous and heavy onboard compressed air tanks, Batteries sill get smaller, air tanks will get bigger.

UGLY: 300 million cars would require at least 150 thousand big huge expensive NOISY air compressor service stations to be built... Ironically, the air compressors will be POWERED BY ELECTRICITY!!! Which should be powering the cars!

WORSE: Greedy "air conglomerates" would just phase out their expensive gas stations and phase in air pumping stations. Wall street tycoons will see air-investments as yet another medium to increase teir wealth so they can buy their 5th house in the Hamptons, and support thier wive's $2,000 a week brand name shopping sprees...

UNSPEAKABLE: Air suppliers would come up with slogans like "let your car breathe so we all can breathe clean air". and gullable people would buy into this thinking... Some things that seem to make sense don't always save cents.

CONCLUSION: Let's keep the air technology where it belongs... in balloons at your fifth graders birthday party. Unless, of course they figure out a way to harness the hot air produced around 1600 Pennsylvania avenue and the Senate, Congress, Dept or Energy, EPA, city and local governements... etc. That supply truly is ENDLESS!

MORE INFO: Go to your local carnival and buy a whoopy cushion. This is what the "experts" sound like when they talk about air-powered cars.
