What about superconductors? How to make them small?

I just opened an email from Tesla Motors, can t remember how they have my email address whether it was me asking about the Lamborghini Aventador being converted to Electric which they ignored, or me following him on Twitter which I hardly use... anyway


I was reading their specs, sucks... 30 minutes "supercharge"


What they need is to miniaturize superconductors for instant charge...


Imagine spots on highways like patches that cars drive over, the moment the car is directly over the patch, the supercharger is instantly charged, and the person is billed shown on the HUD of their car. like "78% charge replenished -$20.00" or something like that.


The idea of "no resistance" of super conductors makes me think that they can be struct by lightning and absorb all of that energy without exploding. But how do you bleed off the energy slowly...


The actual question, how do you make them small and the cooling able to be sustained? If a cooling system like say a closed ammonia refrigeration system that had perpetual electricity say a thorium generator, then is that enough to cool a small superconductor that can power a car for significantly or far more than gasoline can ever power?


Tell me some details about super conductors, how the energy absorbed, capacity, discharge, energy format


I d like to know any information, or not... I ll look into it later.

Normal conductors resist lightning very well. The biggest difficulty is a proper Earth connection. The wire is just 1cm2 or so. The trick is that the atmosphere drops the voltage hence the energy; the wire doesn't need to thanks to its low resistance. A superconductor would improve little over copper or zinc, and these work at normal temperature hence are always ready.

 

Superconductors are complicated both physically (we have no theory for all of them) an technically (we can use very few of them because of process or property limits). Their capabilities are strongly limited and this isn't trivial to grasp. The LHC had an excellent introduction online but it has disappeared, alas. Google for "type I" and "type II" superconductor, quenching, and many more. Wiki is of course a good introduction. Most proposed uses for superconductors fail because the inventors are unaware of such limits: residual resistance, Meissner limited to far below 1T and absent from type II, maximum induction, maximum current density, operating temperature far below Tc to sustain the wanted current and induction...

 

Most superconductors are naturally small, like fibres or films. Making them big is difficult.
