peltier/seeback elements put like 90% of the power into heat generation and 10% into moving heat.

i've found a strange heat effect with vape

zoi (11:33:27)
I've got a cooler bag with a peltier element and a fan. It draws about 10A, too, and cools very poorly.

Agemixer (11:31:05)
yeah... heat pumps are kinda based on fridge effect

zoi (11:29:36)
but those compression pumps move ~3x more heat than the power you put in, so they're thermoelectric magic

zoi (11:29:18)
A compression fridge is 7x more efficient power-wise

zoi (11:28:22)
no, not expensive. they're pretty oldskool. but no moving parts, so they last forever.

Agemixer (11:27:50)
generates more heat than coldness

Agemixer (11:27:23)
like, 10% or less i guess

Agemixer (11:26:47)
zoi isn't it the gas use of a fridge is still the least of effeciency of cooling down?
