The thermal electric cells get hot on one side and cold on the other. The side that gets hot, gets very hot because it is dissipating both the heat that it is transferring from the cold side, and also the heat generated by the electrical current through the device. You have to have a rather large heat sink on the hot side in order to get cooling on the cold side. Reversing the current, just reverses which side gets hot and which side gets cold. You still have the condensation problem on the cold side in high humidity environment. As far as energy efficiency, thermal electric cells are not nearly as efficient as compressor based systems. Just a lot smaller. well, it's smaller and lighter that we'd want. but the waste heat would be an issue. - not that I recall it being an issue with the mini fridge. it might be plausible if you could integrate thousands of micro thermalelectric cells right in the clothing, you would have a fairly large surface area (away from the body) to dissipate the heat. That would also mean that you’re only external body pack would just be the battery. |

And, I haven't had much luck getting it to wear Halloween costumes in the past. But, I trust the cat will take to his climates suit like a fish to water... boiling water. |
