Everything is not limited to considering just consuming energy. I know about the laws of thermodynamics. There are further features about the compressed-air propulsion. Reducing the pressure on the batteries, having their particular advantages, … I know their efficiency is 14% and the efficiency of the electric motors is 98%, but I think that system needs to be kept … I gain electricity by braking: regenerative, piezo, hydraulic, inductive, and thermoacoustic. As a coincidence, the electricity of grid (stored in batteries), sun, and rotating a handle is being pumped into the motors. How do I coordinate all these? I need to apply some electronics, circuits, … I meant damaging the tanks and other components, otherwise it's more attractive than batteries to charge a compressed-air tank during 3 minutes, much faster than any present battery. If you use manual compressors or compress the air gradually, that's OK, but if you do it fast, you should be careful. That's not so. Look at these cars separately. I assure you there is no innovation of mine about this. I respect the experiences of the auto makers which all of them have not been bad tradeoff. I'm telling we should apply useful complexity/simplicity, not useless simplicity/complexity. Grid, and solar are natural, bio-force devices won't be more than 10-15 kg, treadmill is a damn simple tool and you can use it even at home, windmill has nothing to do with the car, it's the government's business, cooling tools are already working in the hybrid/electric car. The compressed-air system is a bit problematic but not too much. The only complicated system is the solenoid electricity that could result in the most amounts of power … Actually, I didn't expect such a volume of objections to my plan. I thank all and I learned many points from you. Therefore, my document surely needs newer versions. I concluded the compressed-air tanks and battery packs should be away from each other.
