Compressed air instead of fuel?

No, it would be more efficient to just use the electric motor to run the car. It's going to take the same energy to fill the tanks and in turn use that air to turn the engine as it would take to just run the car off the electric motor. That energy to move the car is just being moved from one potential energy source to another. Sure, the compressed air can "store up" a lot more potential energy at what I would imagine would be less cost to turn into motion, but it's going to use the same energy to get from point A to point B regardless. I cant understand how anybody would think you only have to fill the first tank once because "the air powered compressor would compress the air tank." What a stupid idea, that's basically just moving the air (energy) from one tank to another with no gain whatsoever.

How many electic cars have you serviced? Im going to guess none because if you ever have you would understand the amount of electricity it takes to comepletely power a car. It takes alot less battery power to run a small compresser than it does to run a whole vehicle. I never said anything about filling the first tank once but if there is more than one tank that is essentially correct, the air in one tank can be used to run the engine while another tank is being charged off of the motion on that engine. The whole purpose of this car is that it takes less money and its using a resource that is free. Have you ever seen the price tag on replacing electic car battery cells? Its extremely high, its not just one big batter its alot of small ones that take up alot of space.

Im not sure if you understand how a car works. But the compressor isnt powered by air it is electric, electricity comes from the battery, the battery is being recharged by the alternator, the pully on the alternator is being turned by the motor? Get it?
