I just got a sweet idea about how to cheaply power a compressed air car.
1. Buy one or more huge,strong air tanks and put them in your backyard or basement or another place.
2. Buy a big solar array and put it on your roof or backyard or another place. To save money and be more efficient, dont convert DC to AC (which results in about 15-25% loss) and dont buy batteries and dont connect to the grid.
3. Connect the solar panel array directly to the strongest DC powered air compressor which you can buy.
4. Connect the DC air compressor directly to one of the big backyard air tanks.
5. During the night, when there is no power from the solar array and the air compressor is off, refill the air car with air from one of the backyard air tanks.
Who wants to crunch some numbers on that to figure out how much that would cost?
