why wouldn't this work?

>>4853166
It would work. Nobody said it wouldn't.

i too am interested in why we dont have magnetic powered engines

I hate you people haha.

>>4853179

Electromagnetic shielding does exist

>>4853204

What is Faraday-cage?

How about we use a material that is diamagnetic in one direction and paramagnetic in the other direction?

Would the magnets repel each other powerfully enough to generate enough power to be worth it?

coulnnt you technically use the momentum concept of an overbalanced wheel, and overcome the friction issue with a magnet to create a gravity powered turbine?

That would just smack into the top.

I've never really thought about it before, but although perpetual motion is impossible in general, we have forces we can utilise, like the Earth's gravitational pull and magnetic field. Doesn't this make it possible to have a pseudo-perpetual motion machine on Earth?

>>4853252

No. Force is not energy. You can extract energy from gravity pulling something down, but you can never extract more than was needed to lift it up.

>>4853252

yeah it's called orbit.

You guys are right! It's actually super easy to build a perpetual motion machine, but nobody has ever bothered because we hate free stuff.

>>4853268
I know, right? I think it's a conspiracy plot by the government!

>>4853278
b.....but it is

free energy has been invented before

>>4853299

and what would that be????

>>4853370

Well, arguably solar power is free. As for violating the conservation of energy, you're going to have to go to galactic superclusters whose gravitational potential increases out of nowhere because of the expansion of the universe (driven by the cosmological constant).

Weight distribution would be off or something;
can't control speed...

>>4853392
Solar power isn't free it's powered by nucular fusion

>>4853458

ikr

some dumb people think it's free because it does not cost them anything
