comment Calculating Boltzmann constant using semiconductor
Thank you a lot. Could you additionally give me some leads to the explanation what do these things mean? I mean, how is the conductivity exactly affected by temperature and what does boltzmann constant do with it.

@Adsy nope. I'm not saying I don't understand that additional energy will be needed to cool object down. I'm saying that I don't understand why the solutions are so tricky, complicated.

Why do you think so? If everything on earth was about 1000 degrees celsions, peltier module wouldn't work any more (the higher temperature, the worse it works). Compressing gas would also be harder, wouldn't it?

If you're right, does the salt decompose during the process?
