Anyone using a perpetual motion machine would want to do something with the work after it's been extracted from heat. If you consider such a system as a whole, work maps to heat maps to work. The number of possible states does not decrease.

No - that's why you can't get a patent on a perpetual motion machine. Entropy does not allow a perpetual motion machine to exist.

The classic definition perpetual motion is not possible if any source of inefficiency exists and a source of inefficiency (friction) is always present in a classical setting. For example, even satellites orbiting the earth will sooner or later come crashing down as a variety of outside forces work against the orbit.

Subject: Is perpetual motion possible for the entire Universe? ... Assuming that nothing can exist outside of the universe as we perceive it, is it possible for the universe to have, what I think would be considered, perpetual motion? Assume that there was a Big Bang, and there will be a Big Crunch.

One method to generate energy that has popped up at different times over the past 100 years is through a perpetual motion machine. According to the laws of physics perpetual motion to generate power is impossible.

Perpetual Motion is almost possible watch! ... snkscore, on 10/10/2007, -11/+60I would just like to point out that the statment; "Perpetual Motion is almost possible" is pretty much the same as saying; ... SkippyDoorknob, on 10/10/2007, -2/+41When it comes to perpetual motion, "almost possible" = "not remotely close"
