It is interesting how the worked it out by "working backwards".
So now we know that something called "charge density waves" is apparently what creates high temperature superconductivity -I have never heard of them!
and these "charge density waves" cause superconductivity by causing "... 'twisted 'pockets' of electrons in these mat ...[text shortened]... m mechanics, this will be something I will now study so that I will at least half understand it.
Yeah, same here. Room temperature superconductivity will be useful in so many ways we don't even know all the apps for it yet. One I think about is superconductive plasma shields for incoming spacecraft, if you have a powerful magnetic field in front of an incoming craft it could deflect the hot plasma around the craft and so there would be no need for those huge insulating bricks like on the space shuttle.
I also wonder what a superconducting antenna would be like for communications and radio telescopes.
If you look at the little formula for Q of a circuit, reactence over resistance, the lower the resistance, the higher the Q so a superconductive antenna or tuned circuit should have very high Q, which would be extremely useful for radio telescopes since they look at wavelengths of less than one Hertz.
I wonder what a parabolic reflector would be like if it was a superconductor, would the reflection be better than a conventional reflector, like in radio telescopes or satellite dishes?
For a resonant circuit, both the capacitive part and the inductive part would need to be superconductive before you would get what I hope would be a large increase in the Q of that circuit.
I don't know if studies like that have ever been done.
I actually tried to set up such an experiment with high temp superconductive wire, I figured I could make an antenna and such with polyflow lines running LN2 and keep the superconductor cold and I approached American Superconductor company with that idea, asked them if they could sell me some wire. SELL me some, mind you, not asking for handouts, but they refused, telling me it wasn't an interesting enough project. The asssholes!
