John the question you raise with regard to the tank circuit is very
valid. But when a superconductor is used as a radiator removal of the
time varying current is consumed by losses
Let me propose the following, presently it is assumed that the super
conductor resistance goes to zero which embraces perpetual motion if
losses disappear. What if the current rose to the surface
like my antenna which is determined as the "Meissner effect". The
material is being bypassed
and replaced in the circuit by resistance traveling along the surface
which gives you the analogy of the long pendulum. One has to be wary
of embracing perpetual motion as in itself it destroys all we have
determined in physics.

Art,

My buss travels another direction, I must leave you here ... good-day!
