Actually, perpetual motion is impossible. It does break the thermodynamics and I believe it also breaks conservation of momentum. That machine will only be useful if it can have an energy output. It can't. All of it's output is going back into running itself, and eventually, it will stop. There are energy losses in the form of heat from friction, and those will wear on the material used to build it. it will stop.
i was talking to my friend about that. do you think the parts would just wear out for it to stop? im aware that its impossible but this is a very cool machine that come quite close. i bet if you used magnetic bearings and make the system levitate you could have it running for years!
you mention energy output. does it need to give off energy for such a machine to qualify?
Perpetual motion means that the machine runs itself off of the energy it produces. To do this it would have to produce
more energy than it took to start the thing going. This would require it to create energy from nothing, which cannot be done. Breaks thermodynamics, breaks conservation of momentum.
I built a machine similar to that, but I hooked it up to a small 9V motor and was able to light a lightbulb. When I moved the stator magnet to initiate the rotation, it worked just fine. But if I hooked it up to the machine (whether by the way he did it or a pulley sort of system) the machine ran to a stop, I had to push it to get it moving again. That says that it, like any other power generation system, produces less energy than it takes to start it.
