Ah, OK, I see you revised your remarks.

My point was this. A Peltier alone does just one thing. It moves a lot of heat a very tiny distance. Then you have to do a lot more work to get the 'hot' side cooled off and get the 'cool' on the cool side where you want it. It can't really be compared to the heat cycle until you build the complete unit. With the heat cycle you have this moving mass of chilled liquid you can do anything you want to. Also you already have a system to dump heat as a part of the device itself.
