Pardon my interruption but I searched for 'use' or 'usage' and came up empty. Anyone can tell a regular guy why it's a big deal and what are the applications? ta

Buckyballs have mass, yet exhibit wave interference. We can make them bigger and bigger, and focus them as if they classically popped into existence.

I wonder if it holds up on very large scales, like if we can cover an atmosphere, or a star in one. What would that mean? Elements now are just variations of carbon structures?

And could we at that level build a virtual one? Develop some exotic particle in the atmosphere, get really precise at moving it around, and model the entire Earth, Solar System or Galaxy as interactions as fullerenes?

Just thinking.

So... I’m an idiot but I have a question: could this theoretically allow for a battery that never loses a charge and/or charges instantly? FWIW— I literally know almost nothing about superconductors...

No, because that would violate the Law of Conservation of Energy, which according to our current understanding would imply that this form of "perpetual motion" is impossible as long as the system experiences some sort of load. [0]

Yes. There’s not applicable commercially viable things based on graphene yet. But superconductivity will be a revolution in many ways and especially in computing.

Superconductivity would revolutionize transportation, low cost medical imaging with MRIs, and weapons. Lots of weapons.

I don’t think I’m talking about perpetual motion at all...

When I say never loses a charge I don’t mean it’s limitless capacity. I mean it could be charged 1,000,000 times without any affect on the capacity of the system? Maybe a better way to say it, a battery that does not degrade with each use.

Superconductors allow for the perfect transfer of electrons without any loss? So like if I had a giant earth sized graphene wire superconductor for this example: could I have the energy travel around the ring indefinitely so long as it’s closed?

Superconductors = flying cars. Finally they are working on something useful!

Better make watertight social control devices if you want to hand everyone alien nose hair trimmers that can level city's. Same for the flying cruise.. Cars.

Some exponential tech, always seems to be 30 years away from legacy humanity. Thank you moderators.
