Personally, I can't see these thermal diodes being at all practical. Far cheaper and simpler to just break up the ice, or pump water on top of it. The maths is pretty simple. The thermal diode can only be at a temperature of the water, at a maximum. It's heat transfer is a function of the

Hi I accept that glacier grounding may have a use for thermal diodes, but in sea ice they're pretty useless. Breaking ice works well, because ice is an excellent thermal insulator. Icebreaker paths are cheap. Broken, the cold air hits the sea, and the water can also radiate to deep space. The
