RE: I am not receiving anything from this list

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.

Wouldn't you still get some kind of inductive/capacitive
losses? Not nearly
as much with AC but unless the current draw is dead constant
you will still
have a varying current creating a magnetic field.

Superconductors are one of those odd things in physics that
don't abide 
by the usual rules.  There is in fact NO significant loss of
power from 
any material when it is operating as a true superconductor. 
The only 
limitation seems to be that superconductivity can only occur
at 
cryogenic temperatures.

In the first example in this thread, "perpetual
motion", an example of 
this is sometimes done in a laboratory.  It has little
application in 
the real world, for example no true perpetual motion system
can ever 
supply any energy to any external system, if it does, its
internal 
perpetual motion ceases rather quickly.  The demonstration
goes like 
this, a superconducting circuit is powered up from an
external source, 
and the source is then disconnected.  current continues to
flow in the 
superconducting circuit with no external energy input. 
There are no 
inductive or capacitive losses simply because with no
external input, 
only DC can flow, therefore there is no induction, nor can
anything be 
capacitively coupled.  In fact, the only way that this
experiment can 
demonstrate that there is any current flowing is by powering
a magnet.
