Compressed air car The principal disadvantages are the steps of energy conversion and transmission, because each inherently has loss. For combustion engine cars, the energy is lost when chemical energy in fossil fuels is converted by the engine to mechanical energy. For electric cars, a power plant's electricity (from whatever source) is transmitted to the car's batteries, which then transmits the electricity to the car's motor, which converts it to mechanical energy. For compressed-air cars, the power plant's electricity is transmitted to a compressor, which mechanically compresses the air into the car's tank. The car's engine then converts the compressed air to mechanical
Mabuchi Motor is the number of rotations per minute of the motor shaft when voltage is applied between the terminals with no load to the motor. No-load current is the current discharged when voltage is applied between the terminals with no load to the motor. Stall torque is when the motor rotation stalls upon increasing the load to the rotating motor, while stall current is when the motor rotation stalls upon increasing the load to the rotating motor. The physics formula E = M (electrical energy input equals mechanical energy output) demonstrates the conservation of energy principle at work in a Mabuchi
