Bleh I dun wanna read all the replies..but like few have said you can't have a perpetual energy car like that. The compressed air can't power the motor that powers a compressor that fills the tanks and makes the car run forever. It's impossible. Like other people have said there is wind resistance blah blah blah....either way though if it really does take 3 minutes to fill the tanks to go 200 miles that is a fraction of the cost of gas. The amount of electricity that my compressor uses in 10 minutes doesn't even come close to 8 gallons of gas. (I figure 200 miles/25 miles per gallon)...hell even if I had a car that got 50 mpg meaning 4 gallons of fuel. My compressor doesn't cost that much.
It's an interesting idea...I'd like to look at one of these cars..I don't see how they can travel 200 miles in a trip before needing to repressurize.
EDIT: And yeah lol whoever said you're just moving the energy from one tank to another was correct. You can't get something from nothing. THOUGH they could have the motor running a small compressor that does fill another tank, BUT it wouldn't put out enough air to completely make the car never need air again, it would just make the range better. It's similar to EV's regenerative braking or w/e it's called where the braking even stores some energy for the car. It doesn't make the car go forever though..
