I'm not sure why you say there is energy loss. The heat you produce e.g. via friction is simply the kinetic energy of the atoms. But because their movement is random, it represents a high entropy and cannot by itself be reused to do work.
I was referring to the heat energy lost after the useful work in a system. The reason why perpetual motion is impossible. I'm sure I've mangled it horribly.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
