see I've been wondering if a heat pump system could heat an oven hot enough to bake bread. use environmental heat to manufacture Wonder Bread or something.
I don't know the answer, but it this did work it would both make the outside of the oven super cold and be so slow to warm up that it would be pointless. Keep in mind that you have to get stuff in and out so air exchange is inevitable, every time you open the door you'd be reducing the heat substantially and it would take a long time to rise back up.
Also my gut feeling is that any practical implementation wouldn't be as energy efficient as you'd hope.
The other part of the idea is use the heat pump to not only heat an oven to bake bread (or do some other industrial heating process) but have the other end cool some process that produces waste heat, such as a data center or something. Or air condition a warehouse.
I don’t see why it shouldn’t be able to. You might need concentric shells depending on the power of the heat pump.
I don’t see how? Using heat pumps to concentrate heat doesn’t seem like a violation of any thermodynamic laws?
They don’t continue to be 500% efficient as you fill their downstream side with heat.
