Sorry, but this is just silly.
The described methods are heat pumps. They transport heat, don't make it magically disappear.
Peltier elements are utterly inefficient as heat pumps.
Magnetocaloric cooling is said to be more efficient than vapor compression. But vapor compression is not that great either.
With all heat pumps you are ultimatively limited by Carnot efficiency. This means with any active cooling you are producing additional heat.

Use the electricity elsewhere? I bet i can make some good guesses as to for what.
Um...they finally took up my proposal to add a Bang and olufsen entertainment system for the pilots liesure on those long missions and flights? Thats my best bet.

Stargate where do you find the drawing of your concept ? By information ? or is it your concept ?

Peltier or any sort of cooling doesn't make cold. It moves heat.
And it takes energy to move heat, and that energy ALSO appears as heat in your heat dump.
So if I wanted to move a steady flow of 30W of heat from my cold side to the heat sink, it will take 100W, say, to do it. On the hot side I now have to get rid of 130W of heat. It won't go away. It just moves elsewhere and gets worse.
