The Electric Car Battery Battle

The compressed air to be used in the MDI car is going to be pressurized to 4500PSI. Personally, I'd rather not sit in a car with a tank pressurized to 4500PSI in the back. If that sucker ruptures, whoever is sitting in the driver's seat is going to become hamburger.

Objectivity is right. Imagine the amount of power needed to compress that air to 4500PSI. When you buy a fillup of that air at 4500PSI, you are paying for the gasoline to run the compressor to compress that air to 4500PSI. Sorry air-car fans, there is no such thing as a free lunch.
