Does that mean a thermoelectric generator operating at a minimum of 0K has a maximum efficiency of
Eff = (N - 0) / N = 100%?

- someplaceguy 2y agoAccording to the formula you'd have to divide by 2*N.
- 11101010001100 2y agomy mistake!
- tullianus 2y agoYes, although in practice you will have issues sinking heat at 0K without using additional energy to do so, since that's below the radiation sink temperature of space (~2.73K).
