What would be the point of a perpetual motion machine?

Lets say that someone invents a perpetual motion machine. One that is possibly realistic and is 100 percent efficient. What could you possible use it for other than possibly as a battery but even then the transfer from the machine to the outside world would come at a cost of efficiency, since if you take any energy out of it it will promptly stop being a perpetual motion machine. So then why do people try to create them when even if you could make one it would be pretty much useless.What would be the point of a perpetual motion machine?If you had the use of a perpetual motion machine you could increase the energy deficit that is created by other attempts to harvest energy sources.



The reason a perpetual motion machine doesn't exist at this point is because of friction and gravity. These two, if eliminated, could allow for much more efficient machinery. A gasoline-driven vehicle, even, would see an efficiency increase of over 50%.



It would cut down on energy costs, fuel consumption, and wear-and-tear on machined parts.What would be the point of a perpetual motion machine?The very existence of a perpetual motion machine would prove that all we think we know about thermodynamics is wrong. It would require a new theory to be formulated. It would show that all our thinking about the conservation of energy was wrong.



If you could invent a machine that produced enough energy to overcome its own friction, then it isn't really that much more difficult to build one that would produce a bit more energy than it needed. And then you'd have a free source of energy! You'd be a hero! 8^)
