I dont, but why dont we all have tec's in our fridges and freezers @ home if they can do more work (i.e the heat pumped through the device) than the power input to do the work? Since they are better than phase change wrt moving parts/maintanance?
Also thought experiment:
I take the coldsides of a large number of tecs and place them, for arguments sake into the sea, then i power them up, they then remove heat from the sea , the heat i get from the sea has more energy than i need to run the tec*. Correct and with me so far?
So I now boil water with my heat removed from the sea (and the hotside of the tec), generating electricity, which is more than enough to power the tec* and have electricity left over to power my computer.
*Since in your regieme its possible for a tec to pump more energy than the input energy
Hopefully that illustrates why you cannot get more work out of a system than the input work/energy/power (all one and the same) And also it illustrates why we have phase change rather than tecs in our fridges since phase change is ~75% efficent whereas tecs are less.
