>>14137914It works, but you know that you have to cool the hot side, right? If you just put power through it then the cold side stays at room temperature and the hot side heats up. You need a cooling system that can remove more heat than the total power rating of all the units because the system also absorbs heat from the environment. The colder it gets, the faster the system absorbs heat and the more cooling you need. You'll need like a dozen units depending on the delta T, a power supply that can deliver around at least a kilowatt at the appropriate voltage, a cooling system capable of dissipating all that heat, and a small, insulated chamber to cool so you aren't trying to cool the entire room. Good luck.
