Place a glass of hot water and a glass of cold water on the table.  If you
know how, you can run an engine by transferring heat from one to the other,
until the temperature difference is gone.  Or you can just pour the two
glass of water together to get two glasses of tepid water.  In that case you
would have wasted the available energy--the temperature difference is gone.
You wind up with the same two glasses of tepid water, with the same total
energy, but nothing to show for it.  Heat cannot produce work unless it can
flow to a lower temperature.

True. But the experiment you've set up is not fully equivalent to the
original case. Try this. Set up two glasses of water of different
temperatures. Extract energy incompetently so that some of the heat
leaks away to the surrounding air. Before the temperature can equalize
with air even further away, with suddenly greater competence extract
the energy from the temperature gradient in the air. Voila, the leaked
heat has not been wasted. Repeat ever further away until the amount of
energy recovered from the ever-decreasing temperature differential is
too small to be measured. At this point the energy loss, though
theoretically suspected, is also too small to be measured. Now good
old Trev, for once in his miserable life, can be right. Kiss my ring,
Trevor.

In the Middle Ages (when global warming was Good) whole monasteries of
monks did this sort of hairsplitting their entire lives when, because
of global warming increasing agricultural yields so excellently,
communities could for the first time afford whole classes of idle
speculators.

Of course, Michael Press will now point out that you and I have
committed the well-known Physicist's Solecism of ignoring the energy
lost in the machinery and measuring instruments.
