<<yes, but the difference in this case is that the air charged tanks don't lose power over time as batteries do.>> Depending on the volume of the air tanks and the pressure, you could graph the loss of power and distance travelled as the air in the tanks deplete moving the car. You would probably have no problem climbing a long hill on fully charged air tanks...how would you do climbing same hill on a quarter of original pressure and volume?Similiar to batteries ...no? Have you ever used air tools?If using air sander for example, you can feel the loss of power, and hear it, as the air in the compressor tank goes down to the cut in point of the compressor and build again to cut off. Re the last part of your post...as i have said before compressors are energy hogs...extremely heavy load when they first fire up and have high RPM for pumping air after that.Carrying a high pressure compressor around in a car would not be ideal either.. adding weight. It will become apparent as time marches on which new technology will win the race...I am betting it will be batteries such A123 or VLNC feeding efficient wheel hub motors directly (UQM) ...no transmission ,the wheel hub motor being the transmission.
