Why hasn't society used the capabilities of magnetic powered engines?

It's free, it's clean and the polarity of magnetics stay for up to 400 years.

Is it because oil companies have already bought off most magnetic engine patents?

This is just a picture I took off google imagines, there are plenty of youtube videos with a bunch of different forms of the engine.

There was another video where a man managed to produce up to ~9.5 volts of power just by positioning a rod over a series of magnets.

All he did was give it a little push.

I think most people assume you're trolling, because what you're saying sounds extremely retarded. It could be that you're sincere and just stating what you mean poorly though. If you're not just making some claim about perpetual motion, perhaps try elaborating?

IN THIS HOUSE WE OBEY THE LAWS OF THERMODYNAMICS!

>>Is it because oil companies have already bought off most magnetic engine patents?
In that case, all we have to do is wait 20 or so years for the patent to expire.


Though the question is, could one really build a magnetic engine, THAT DOESN'T VIOLATE THERMODYNAMICS? IE, you give the engine unseperated magnets and combination of said magnets drives the engine.

>> No.4814713

i believe that's the idea. it is not perpetual, it only lasts as long as the magnets maintain their polarity, which might only be for a few million years at most

THEN WHERE DOES THE ENERGY COME FROM? When magnets are magnetized energy doesn't get stored in them, it gets dissipated as heat.


That being said, engines that run on water are a lot more likely to happen than 'magic' magnetic motors. In fact, one could be built to supply power to parts of Arizona:

Magnets can't do work they can only be arranged in a way that friction is reduced or nearly eliminated in the system, but external power or energy would still need to be applied to make something turn to generate work or electricity.

>>4814648
> Why hasn't society used the capabilities of magnetic powered engines?

Because magnets aren't a source of power.

>Is it because oil companies have already bought off most magnetic engine patents?
Possibly

Very likely.

Cracked has an interesting article on GM destroying the electric street car:

Look up "a practical guide to free-energy devices." With little external applied power you can generate a significant amount of electric power. Depends on the device.

>All he did was give it a little push.

And that's the rub. He got a little energy by inducing a current by moving a wire(in this case a rod) through magnetic fields.

In order to KEEP that electricity flowing, you'd have to keep pushing, which means you're continuing to put energy into it.

>> No.4814810

I think everyone's come up with the idea of building a magnetic motor at some point, some people realize they don't work based on theory, others have to build one to realize that it doesn't work. It's part of the process of growing up IMO

Actual measurements on the 50 kW Manzanares pilot solar updraft tower found a conversion efficiency of 0.53%, although SBP believe that this could be increased to 1.3% in a large and improved 100MW unit.[8] This amounts to about 10% of the theoretical limit for the Carnot cycle. It is not unreasonable to expect a similar low conversion efficiency for the Energy tower, in view of the fact that it is based on a similar principle as the solar updraft tower.

you need to use energy to create more magnets.

they wear off very fast when used for powering engines.

sorry OP. it's of very limited use.
