What happens if you put 100 of these in a box? I have a feeling it's going to be tough keeping the ones in the center cool.

- recursive 2y agoIf they all start at the correct temperature and you keep the outside ones correct, then it will be easy. This doesn't apply if the the these packages have some internal heat source.
- gumby 2y agoThe battery is an internal heat source.
- recursive 2y agoBatteries don't produce heat unless they're discharging (or charging). The thermostats in the middle of the pile would stay on the setpoint, so no energy needed or used.
- bryanlarsen 2y agoPeltier's are crazy inefficient, they produce a lot of heat.
- everybodyknows 2y agoExactly. TFA says "heat pump", but the imp on my shoulder says heat pumps don't scale down to palmtop size and it actually runs one of these, a thermoelectric cooler: https://lairdthermal.com/products/thermoelectric-cooler-modules https://lairdthermal.com/products/thermoelectric-cooler-modu... Efficiency is much lower than pumped-refrigerant systems. Access to a flow of cool ambient, external air will be critical.
