So this is the idea:
(taken from Iron man, i suppose)
- The idea is making a superconductor into a ring,
and then charging it using a coil...
once it is charged,
you can remove the coil,
and you have stored electricity in a ring.
The big idea is to actually charge a superconductor ring with a lightning bolt :)
with no resistance, the conductor will not produce heat,
and you can keep it cool under liquid nitrogen.
* you can harness the energy from the ring by using a coil,
or you can put it in a magnetic field, and make it turn.
(i will expand this idea under motors)
...
so on a small scale,
you can short-circuit a dynamo
and remove the magnets from the dynamo,
once you charged it sufficiently...
* there may be some interference when charging a dynamo
that is short circuited... seeing that you may be draining the magnets, instead of using mechanical energy to produce current.
Up to today you have to cool something down to absolute zero to get a super conductor. Which will consume more energy that you will most likely create. I did read some where that some Canadian college students made a super conductor out of gas hydrates at a higher temp.
There are some high-temperature superconductors that can be kept cool by liquid nitrogen. You can read about it on Wikipedia.

superconductor batteries may only be for very high currents that are stored...
I am still not sure how much current a normal copper wire can store... its called the ampacity of a wire... but depends on the physical dimensions also...

Yes you can cool a super conductor with liquid nitrogen. But where will you get the energy from to cool the liquid nitrogen. The energy it takes to cool the nitrogen will be more than you can create. Those temperatures that you saw on that link is in Kelvin not Fahrenheit. 77k = -196C= -321f
