Perpetual Motion

By Josh Layton

Could it really exist?

Can machines power themselves? Yes. Can they go on forever? Well, that's a different question. First of all, to test if something goes forever, you would have to observe it once a day, forever. We don't have to wait forever. We know it will not work. Due to a thing called dissipative tidal force the machine loses mechanical energy initially imputed gradually over time. You can think of dissipative tidal forces like gravity, slowly pulling things over time.So, although the fundamental laws of physics do not prohibit perpetual motion, we have yet to find a way to manipulate it.

Why don't we use perpetual motion to get unlimited energy?

Machines can only cycle on the amount of energy imputed into them. So, a machine would need to have an over 100% efficiency to produce extra electricity. That is not exactly possible for a machine would not work running over 100% due to overheating. Someday we may be able to use perpetual energy by making a 200% efficient machine

Perpetual Motion Machines

Is it safe and clean?

The answer is no. The only way that we could make energy from perpetual motion is by linking one to the other to charge each other. Think of it like this, If one perpetual machine has 100% energy left over, and puts that into another machine, it is going to produce twice as much. So if thousands of machines linked to each other are at the same time doubling each other, this would create infinite amount of energy. But remember, perpetual motion machines run off of motion. This motion produces heat. This would be A LOT of heat. This heat would very quickly overheat the entire world.

All in all, perpetual motion could never exist, and we wouldn't want it if it did.
