Thread: Serious question for people smarter than me.

Well, common sense says nothing is permanent and perpetual motion machines don't exist. It's not that you need energy to get it going, you need energy to keep it going.

To my knowledge the closest thing to an perpetual motion machine is an Atmos Clock. It runs on temperature changes in the room.

Ok, never heard of them, but there's lots of things I've never heard of.

These are very effficient clocks run that just run on a different energy source.

But they still use energy.

Yes, I have one. It's a matter of reducing the energy required. A self winding watch uses wrist motion which is excess energy like a solar watch that used the sun or light. The Atmos uses temperature change to power a chemical reaction to wind the mainspring. A 2 degree change a day in enough to keep it going.

Yes but they all use energy and use and loose it.

Well, yea that be the whole idea that there's no free lunch and no Perpetual Motion Machine.

It is true that permanent magnets aren't permanent forever, but that's not really relevant here. The relevant part is that generators don't "generate," they convert. If you want to "generate" electrical energy, you must convert some other kind of energy into "electrical energy." For a motion-based generator, one form of energy is converted into kinetic energy, which is then converted into electrical energy. Without an input of energy to convert to kinetic energy, the generator will stop. A system permeant magnets that repeatedly attract/repel that functions as an electrical generator would stop rather quickly.

My most efficient clock is my sundial.

Does it compensate for the wobble of the Earth and "The Equation of Time?" Actually it's not efficient because on cloudy days it doesn't work.

Har har.

Hey Big, I just rewatched the documentary about Tesla on Amazon prime, yes he did invent a/c that we are using today. Give it a watch. I was wrong about the feds coming the next day, it took them two...
