    Nice video! As you requested, I produced a video a few months ago where I go into more depth on the quantum process that generates this cooling and heating effect.

      Your channel is where I first learned about these devices, and your videos also had more details like how the voltage and the temperature affects the performance of these devices. I'm quite surprised that Mehdi didn't give you a shoutout.

      Though I'm not an expert, I don't think this explanation quite nails the effect. It describes the Peltier effect as a chemical phenomenon where electrons give energy to a nearby dissociated electron at the junction, whereas it neglects the fact that electrons freely associate and dissociate constantly in a conductor, with varying energy levels, and the electron moving in one conductor never actually has to cross the junction to create a current in the other (how do capacitors work?). I anticipate that, if the Peltier effect really worked as you describe, a thermocouple replacing a capacitor in an R-C circuit would have a "capacitance" as the charge carriers "accumulate" at the junction, waiting for their neighbors to spontaneously give them enough energy to move. Difficult to measure, though, since you'd also have junctions with your measuring device, the source, the resistor, etc.

    Hey electroboom. I'm throwing this off the top of my head, but maybe the electron transfer phenomenon between different materials cools the emitter due to the difference in work potentials between the different metals. I haven't done any research on this so it might be inaccurate. Just a thought though :)

    I wonder if you could use these, fun experiment scale, to power a sterling engine (to create the temp differential) to then power a small handmade and thus low friction generator, to then feedback power to the thermoelectric device? This isn't to make a free energy device - slightly difficult ;), but as a fun idea to use them... ?

    adding too many fins on a surface may actually decrease the overall heat transfer when the decrease in h(convection heat transfer coefficient )offsets any gain resulting from the increase in the surface area.

    3:13 tl;dr: different atoms pull differently strongly at their electrons, so it takes energy for an electron to travel from a "strongly pulling" atom to a "weakly pulling" one, and releases energy the other way around, so if you force them to travel by applying a voltage that releases or takes up heat to achieve the transition. as you then said at 6:00 the peltier element is just lots and lots of those junctions zigzag aligned so the "weak to strong" transition is on one side, and the "strong to weak" one on the other side, which means on one side the electrons need to soak up energy (as heat, thus cooling it) to travel across while on the other side they get rid of that energy again, heating it up.

    Sooooo, the electrons can carry away thermal energy as they move across the electric potential, might have todo with that fact that the electrons gaining energy and by moving away are causing the entropy of the universe to increase.

    It's highly recommended to use good performance water cooling on the hot side.
    Also It's recommended to get the biggest peltier you can get your hands on and run it around half the specified voltage, as peltiers do have a decent COOP at around half their voltage (then also the current drops significantly) and around 30 degree delta between hot and cool sides. With a really good water cooling setup it's possible to create a fridge (not a freezer) that might get COOP not much worse than compressor cooling.
    Also If one wants to create fridge it's also recommended to use a smaller water cooler on the cool side, so that the radiator sits inside the fridge, providing heat intertia, and additionally you can insulate the peltier/pumps from the fridge eliminating thermal bridges.

    One last thing, It's possible to PWM control the peltier cooling power, as mentioned on some nasa website (should be able to find in easily on google looking for "Peltier PWM control"), although it would be nice to experiment with constant voltage control, and with constant current control, as that also might have it's benefits for efficiency of such setup.

    Water cooling such setup has another benefit of enabling the hot side radiator to be moved outside of the room/building etc.

    Use computer cpu heatsinks as they are way more efficient and also have the hot side on top and have the fan pulling air and pushing it up to the ceiling. I have managed to get a 60w peltier cooler to -34°C with a noctua heatsink and insulation around the cold side

    Thermal energy is considered to be a variation of kinetic energy based on the principle that all particles are constantly vibrating, so maybe on these devices particles from one side of the device transfer to the other so that matter concentrates there, therefore raising temp....? maybe? Idk, its just a guess, didn't look it up.
