Ian;
I once learned a poem - Twinkle, twinkle, little star
Power = I sqared R
And I got beat about the head and shoulders by a math teacher, it finally
sank in that anything multiplied by zero is zero.
Soooooooooo, you must be talking about the power loss in a superconductive
circuit???? However, you'll agree, I hope, that there'll be a small loss in
power; otherwise we'd have the Perpetual Motion effect. There's going to be
a small loss in power, because I don't really think there'll ever be such a
thing as a perfect superconductor.
BTW, I'm thinking of starting a thread about the weather. The weather up
here in Central B.C. is really weird, rain, thunder showers, sunshine;
haven't seen anything like it before. We also had a long, cold, winter,
temperatures down to -35 F, lots of snow; it's claimed to be caused by
global warming, greenhouse effect or whatever.
Any comments?
Pat

What you want is a super-conducting alloy that is cheap to manufacture
and provides superconductivity at Earth surface temperatures, then you
won't lose any power in transmission because the R in I squared R will
be zero.
