Perpetual motion machines are designed to produce unlimited energy. In other terms it runs for infinite time. But in doing so it violates Laws of Thermodynamics. It has been classified by the law which is being violated in the machine.
This wood burning stove is small, simple and is stacking functions because it is also serving as a water heater.It serves the Teach Nollaig tiny home and we think it is beautiful and amazingly functional.
Just imagine what it would be like if we could generate free energy. No need to worry about pollution, or fuel, or effort, or anything. It's no wonder so many people have tried their hands at building perpetual motion machines. And thanks to the magic of GIFs, none of them ever has to fail.
Actually they are Over-Unity machines, see 9 GIFs That Make 'Perpetual Motion' Machines a Reality, actually its crap, as perpetual motion defies the law of physics, sort of like the guy who walked on water.
