Stacking of Peltier units - Part 1

In this video, I want to discuss some ideas and thought about the stacking of several Peltier units. As the discussion ended up being quite long, and the experimental part is also very long, I split the whole thing into 2 parts. So, in this part, you will see the calculations and will be able to listen to some discusson, and in the next part, you will see all the measurements and experiments. I hope it will worth your time.
