That is your fallacy. A generator (not even a theoretical ideal one)
will not supply one watt regardless of the impedance it sees.

In what way is it a fallacy? There are theoretically only two possible
conditions where it is impossible. Do you know what those two conditions
are?


I should not be asking that question. I should be supplying some
information. I apologize.

The two conditions are a zero ohm load and an open circuit (infinite
load). It is not theoretically possible to put power into either. Those
two conditions require a source such that the results are,
mathematically, undefined.

But ALL other conditions are theoretically possible.


I don't think a true open circuit is actually possible, though one can
make a pretty good approximation.



Correct. And neither is a true short circuit. But, I was sticking to
theoretical conditions rather than getting into how much of a short or
open circuit really is.
