Yes, that is quite correct Cecil, and nothing that I have written says
or implies or is intended to mean otherwise.

However, your own words in another post
(news://news.bigpond.com:119/c8b7540a...oglegroups.com)

"A 60 Hz Power Generation Plant operates at high efficiency, not at the
maximum power transfer point. If they were 50% efficient, they would go
out of business."

demonstrates that whilst you apparently can quote from text books, you
do not necessarily understand what you are quoting. You do talk nonsense
sometimes!
