I've wondered about doing something like this using an old Eight Sleep topper from eBay or something. Eight Sleep seems nice but waaaay too expensive, and then having a subscription for a system that as far as i can tell just amounts to timed relays is absolutely absurd
Unfortunately peltiar plates are 9 times less efficient than a phase change heat pump. Meaning running an ac and cooling your whole room is still more efficient
That's not as simple a calculation as you seem to think. If you're using 9 times the amount of power to cool a given mass, but you are cooling 1/9 the mass, it's a wash. But of course then, you have to start thinking about when cooling the room, how much of your cooling is lost to the walls, and when cooling the bed, how much of your cooling is lost to the room.
Smart. Feel better buddy.
This just needs a cool acronym and you're golden!
I'll buy 10 😂

Your design could be mass produced, time to contact a bed/mattress producer 😉
