Whoops... I was originally going to say pluto but I figured jupiter was alot warmer so I went with that. I obviously missed changing all of my references to the "target for cooling", which was jupiter, so I can see the confusion. But then again, that was only an example. By no means do I expect it to scientifically 100% prove my hypothetical approximation of theory but with basic scientific knowledge and imagination, along with knowing how this engine even works, you can understand the point I was trying to convey.
