Can I do better

the entire automotive industry has already done better. Compressed air is a stupid choice for automotive fuel. You would need to (somehow) compress it to about 800,000PSI in order to maintain the same energy/volume ratio as gasoline.

Also, the simple act of compressing air is about 20% efficient AT BEST, and that energy has to come from somewhere. After the 80% energy loss of compressing the air, we would see another loss as the compressed air is decompressed to power the car.

I have seen these engines run effectively while usefully producing about 40% of the potential power stored in the compressed air tanks.

Seriously? You expect a car built out of pure STUPID to save the world?

Barry's Response - Perhaps these are reasons why the compressed air car has not been as popular as one might think. If these statements are true, they present serious practical issues in making these cars a viable (and reliable) medium of transportation.

That's not to say it warrants abandoning all research. Just that there's still a ways to go. Can I do better? Can we get better search this site for vehicle efficiency and reduced air quality impacts? We shall find out. Thanks for your provoking argument here, Biggie.
