Re: Thermodynamics and Lenz's Law

Hi!

I would appreciative clarification or correction:

1, CB's kids are correct? (a true analogy?)

2, There are two kinds of "perpetual" motion machines. Both, I think, have been
alluded to and conflated. One is simply a violation of energy conversation, the
other of probability, which will not result in perpetual motion, but more motion
than probability permits.

Panzers,

bc

Thanks to both John and Brian! Energy is a perspective from which I can
approach this and feel on more solid ground.
