i got an idea...

you know how the moon and satellites revolve around the earth?

well (hypothetically speaking) what if you built a huge tube shaped ring around the earth and tethered it to the earth so it will remain stationary, and then took a giant ball or what ever, and put it inside the tube, and let it be pulled around the earth by gravity?

wouldn't that be perpetual motion?

or what if you could dig a hole through the entire planet and and drop a ball in their and let gravity pull it toward the center, and come out the other side of the earth where it would be forced again to fall to the other side overand over again? or rather than drilling through the center you could drill to she side: illustrations:




you dont have to use a ball but if you know anything about generators then you know that you need movement.

(yes, i know that the earth will be destroyed millions of years from now, but if you create a perpetual motion device, destroying it doesn't change the fact that that it was perpetual.)

how would you reap the energy from this??

how the fuck do you think?

its a fucking generator.

you need a magnetic field
motion and a conductor.

and also i never said it was for generating power. its about perpetual motion.

and i didn't get technical because im not an expert and im way to lazy to go fact finding.

I know the "hole through the center of the earth" method won't work, the ball will clearly lose kinetic energy the same way a ball dropped on a table will.

As for the gravity and orbiting earth theory, I suppose it would work but modern science and building materials aren't going to cut it, also there would be no way to harness the energy created. An interesting idea all the same, you might want to check out that deal in grifith(sp?) observatory in california, it seems to have achieved perpetual motion

Neither of these would be perpetual motion, and they would be bad generators as well.
Besides the obvious energy debt caused by the construction, losses in speed due to friction and converting the mechanical
energy to electrical energy would cause the ball to come to a halt at the closest point to the centre of the earth's mass.

The tunnel through the planet would have an air pressure considerably higher than one atmosphere, and the resistance that goes with that.

A good rule of thumb is: if you think you've discovered perpetual motion, you haven't.

Excellent idea if you ask me. I think its highly possible that we'll be able to exploit the earths gravity from outer space. I think exploiting the earths magnetic field is more viable though. Super conductors revolving around the earth.

what if you built a giant generator (the size of the earth) and then put it in a vacuum?

hypothetically of course..

(and i know space is a vacuum, but the earths got an atmosphere, the generator wouldn't)

fuck you.

If you simply wanted to generate power you could dig a much smaller hole and harness the geothermal energy,
or harness the gravitational pull of an orbital satellite for tidal energy. But you're not after power, but perpetual motion.

The Moon orbiting the Earth is much closer to perpetual motion than your 'ball in a torus' construction, as are the electrons in a Helium atom.

Um ya if you want to do that fine but we have big bright thing in the sky that produces a lot of energy and we just have to find a way to harness it all.
