Only in closed systems. If you can suck useful work out of ambient air 
temperature, that counts as "free" energy in the "gratis" "no-cost" sense.

That is, it's in the same sense that running your car on solar energy is 
"free energy", even tho obviously the sun is supplying the energy and is 
running down much faster than your car is speeding up.
