... Other forms of energy can be converted to kinetic energy with 100% efficiency, which can then be converted to heat via friction, with 100% efficiency. Thus one can say that it is possible, at least in principle, to convert any other form of energy into heat with 100% efficiency. But the reverse, nam ...
