Wow!  I hope I live to see the 'future'!!!!

Magnets are the key to free energy.  Mount them at an angle on a wheel and place another set opposite such that there is perpetual rotation.  Attach a shaft to a generator and voila, power!

BTW, magnets, how do they work?

The first law of thermo is not strong with this one

It's not. Superconductors have very interesting interactions with magnetic fields. And though I've never seen anything like this before, I think a superconductor could be manipulated such that this is possible.

do you have access to copious amounts of liquid nitrogen?

maybe if you just put a big enough heat sink on a superconductor it would just suck all the heat out of it leaving it very very cold and then you could use it on magnets to make perpetual motion machine that changes the world.

It actually isn't.

Superconducting materials have interesting properties... one of which is to exclude magnetic fields from within the material.  The key to this particular trick is that there are a bunch of tiny spots in that disc where the magnetic field can penetrate.  These penetrations serve as tethers to hold the disc in place within the magnetic field.  

Think about unwinding a spool of wire.  You put a screwdriver or rod down the center of the spool to hold it in place while you reel the wire off of it.  The same sort of thing is happening with that little disc.  The magnetic penetrations are going around/through that disc, and pinning it in place.

As I said in the other thread, finding a superconductor that doesn't require very cold temperatures would be an amazing discovery.



Also, I dig the groovy music in the video.

Physics class, how did it work? We did this in high school and college, how is it new?

That's pretty damn cool.  

What would it take to do that on a large scale?

I see, the penetrations act to hold it not only away from the magnet, but also towards it... Very cool.

But don't superconductors have to be... Like, fucking cold? How can he touch it with bare hands?

If you put a jacket on the magnet it will go faster when it gets colder.

Cool, the Meissner Effect. They were able to do this shit in the 30's. Where the fuck is my flying car?
