My scheme simply can NOT work as I realized before I even posted it, because
the absolute max efficiency of a heat pump, which depends only on the absolute
temperatures of the hot and cold sources, is exactly equal to one over the
absolute max efficiency of a heat engine working with the same temperature
sources (the formulae derive from the W and Q formula Ron gave), so that if
you increase one you decrease the other, and when you multiply the two the
very best you can get is a global COP of... 1. ;-(
Actually, Michel, no one was fooled by your ruse for a nanosecond, as I
am sure that you must realize but nevertheless, it is interesting to
continue the thread to its logical ending ...
...which is this: what you have stated above in not necessarily true:
i.e "when you multiply the two the very best you can get is a global COP
of 1" ... as you have neglected a very important point.
So let me challenge you: can you find the fault in your own logic?
Hint: this will involve expanding the formula outside of its local frame
into a larger frame of reference .... somewhat as a microcosm of the
differences between SR and GR.
