Which brings up a point I've been unhappy about for a _long_ time.
We don't have a shortage of energy, one way or another we can
generate/capture enough for most purposes that are currently relevant,
the problem is lack of a sufficiently energy dense storage media (btw,
the jet pack of the '60s used H2O2).
If my understanding of super conductivity is correct, a super conducting
coil should be able to store an arbitrarily large amount of energy.
Is this correct?
