So is free space a superconductor?

Perhaps a superconductor with zero conductivity?

 

The jolly old electron buzzing round and round the jolly old nucleus (in free space) conforms to this definition.

What about magnetic limititations of free space (permeability) and it's effect on charge flow in free space ?

You sure it's not just an abstraction?

 

Thing is, superconductors are a quantum phenomena, not to be confused with classic physics. They really are zero ohms internally, and will conduct current in a closed loop eternally.

I would like to learn more about this. Sounds like a fun little puzzle!

 

As you all know, every conductor material on which current flows will have some power loss due to Joule heating. This means that if a material is said to be conductor, it has some electrical properties which depends on circuit theory. On the other hand, we all know that V=I.R is a special version(w=0) of the Maxwell equations. Hence, the formula is not so reliable for every cases.

I think most of you watched the Atom documentary which was created by BBC. I forgot the name of the professor but I'm very impressed. One of the gurus of the Quantum Physics said " If someone thinks that he/she undertands the Quantum Physics, he/she has no idea about the Quantum Physics at all." If I am wrong, please warn me but I don't remember exactly. I think this was told in a part of that documentary, and it explains so much..

Anyway, I think I wrote so much, sorry about that. I want to say that we're happy with our simple and basic Circuit Theory..

Best Regards

Amen to that

 

Talking about an electron zipping around an atom in a lossless mode, I wonder if a superconductor hasn't figured a way to allow them to wander freely using a version of the same mode.

Niven's books excited me with a description of a room temperature superconductor also being a thermal superconductor. It took me a while to realize the two phenomena, while real at low temperatures, weren't completely linked. But the base concept is cool. Imagine a bar of unobtainium where one end was in a blast furnace, and the other in liquid nitrogen, yet the bar was the same temperature throughout. It would do marvelous things to liquid cooling systems, a "pipe" with no moving parts. Bury a huge grid under every house and never pay heating or cooling bills again.

There is no sign that such a material will ever exist, but it is exactly the kind of serendipity you might expect from high temp superconductor research, and hope springs eternal. On my part at least.

I keep researching superconductors on www.physorg.com , they keep finding new materials and bumping up the temps a few degrees every year or so, but reading between the lines it has physicists confused as hell. There is a very good chance we'll have new types of devices using these materials within 10 years, a personal prediction. Zero ohms means capacitance losses become less meaningful, and electronic speeds go even higher.

As to no viscosity fluids, we may never see them in our temperature realm, but their uses also boggle the mind. Arther C. Clark wrote about them in a short story (actually this was simple polymer that turned water into a very low viscosity fluid) that was used as a murder weapon. Helium 3 (which is a state of helium around a degree or less from absolute) wants to "climb" out of the glass from what I understand.
