ah, there's my confusion.  I never thought about someone specifying
that a material can produce a certain amount of given current, but now
that I think about it, that makes sense.

Thanks for setting me straight.

We were musing over the things you could do with an instant-charge
energy storage system. One silly idea we came up with was electric cars
that charged every few hundred feet down the road rather than the old
thought of putting power lines every inch of the way.  Imagine your
speed constantly being varied like a sine wave:  speed up as you
charge, and effectively coast with a little bit of energy you have
stored.  amusing, but not very feasible (or efficient!).
