This is huge, is it not? No loss in potential energy means that I could have an infinitely floating coffee cup without the use of power, no?

It is absolutely huge

It means that you can make supercapacitors which have larger energy storage density than our current batteries by who knows how many times

What's the connection between conductivity and capacitance?

It's been a while....

[-] xkforce@lemmy.world 15 points 1 year ago

If it were real maybe. But having read the paper, I am very skeptical that it is.

I didn't read or watch the video yet, but if it works like the current superconductors, the magnetic fields will be repealed and cannot enter the superconductor.

However currently is it possible to make superconductors with impurities allowing the magnetic fields to enter (through the impurities) in the superconductor. This allow quantum locking / magnetic locking.

https://en.m.wikipedia.org/wiki/Flux_pinning

However as said above, you need a magnetic field. So either a permanent magnet or by generating one with electricity use.

Another interesting thing is that superconductors allow to store electricity for an indefinite amount of time. Like you put eletrcitiy in it and it will still be in it after 20+ years. However it is not an infinite energy. If it generates work or it is extracted from there, it will dissipate. As the energy will be used up.
