# Thread: Closest to Perpetual Motion

1. Is there a record for a device that has remained in motion (only running off gravity and physics) for a record length of time? Like with the energy output closest to 100% and least net loss. I'd like to know the design for it. I realize this wouldn't qualify as "perpetual" motion.

2.

3. Running off physics? As opposed to running off geography?

4. lol

5. Have a look at the Perpetuum Mobile by Reidar Finsrud.

There's a video link here.

6. I think MIR did quite a good job.

7. How does it work? Any ideas? I suppose a power cord being connected somewhere to be honest.
Otherwise it's astonishing.

8. If a machine that uses its own weight to operate, is placed in a vacuum, where the only force it has to oppose is its own weight, so all the kinetic energy produced by the fall is converted to potential energy needed to bring the object back to its original position, and no energy is lost due to air resistance or friction, of course its efficiency will be zero, because there will be no energy output. But assuming that the above conditions could be provided, will perpetual motion be theoritically possible?

9. So if we create a perpetual motion machine which covertes all its potential energy into kinetic then back to potential moving perpetually disregarding the fact that as it moves it must give away its energy into its surroundings or its own mass what use would this me anyway. It couldnt be used to power anything all it does is prove the indestructablility of energy and convert energy from one form totally into another.

10. energy can neither be created nor destroyed. It can change the state. :wink:

Yeah, i know it will not produce any power or anything, but we could use it for decoration :wink: . I'm sure it will look pretty.
