    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.

      With great respect to the professor, which appears in this video, but I think that some people resort to the science of the atom when they are unable to explain some of the phenomena invisible because most viewers can not judge their words if it is true or false and The other category of intellectuals call for understanding and when you ask them to apply what they understand standing helpless skill lies in communicating the idea in a material way if the explanation addressed to everyone.
      I repeat my thanks to you and to the Professor as it seems to me.

      I think you can make an automatic surface fridge. If you could find a way to use the cold surface to also create/freeze ice / recycle water in the basin to form ice that then which is automatically and continuously dumped into the heatsink basin to maintain the temperature differential as ready. You could protect the live wires and circuitry and quite possibly* install it* in* your countertop. You may or may not need 50+watts for it. You might be able to find a more heat conductive material that which has better cooling properties as opposed to generally being a good heat conductor*. You could also find a plastic cap, glass*, insulated* / lid that is tall enough to cover a soda can for instance. Just for fun. Or to cool fruit that you've cut you can leave it on your counter and cover it with it running at a variable minimum wattage.

      I hope someone experiments with something like this!

      @Red Lightning Sky we adress an ideal fridge as a device that absorbs energy from cold reservoir and radiates it to hot reservoir by consuming energy in form of work.
      But in heat engines we grab some of the energy which is transferring between the two reserviors and convert it to work.
      So a good fridge is an awful heat engine and viseversa so if these are a type of fridge then if used as a power generator, its vivid that it would be less efficient(note that these are heat engines too but they move electrons)

      I wonder what would happen if you stacked them? Since they each do 20 degree difference, it seems like it would pretty cool on the cold side, although I am afraid to think what would happen on the hot side.

                Maximilian Stucke  2 days back

                Simplified explanation: On the cool side, electrons are exited to higher energy levels in their orbitals. They then travel to the oder side, where they drop down orbital levels and release their energy as heat. So in that sense, electrons transport heat energy. From that idea, one can easily conduct, that the negative side must be the cold side - as electrons are drawn to the positively charged side and release energy there. In practice, this only really works with semiconductors, as metals have free moving electron clouds, where any order would just quickly disintegrate.

                          I've seen the particle detector video, and one of the best ways of cooling a heat sync with air, it's sucking the air, not blowing it into the heat syncs. Same goes for any liquid, and this DIY project can be more efficient if you make a circuit of cold water like a chiller uses.

                              These things are made of doped (n & p) semiconductor junctions, which naturally show a potential difference at the interface. Running a current through them only works when electrons at the junction pick up or give away energy from or to a different source, depending on the current direction. In this case they pick up the energy from the lattice in the form of heat, this cools down the system. Of course this energy does not vanish, the electrons carry it to the next junction which is the other way around, so the electrons give the energy back to the lattice, and the other side of the thermoelectric element heats up.

                                              5:35 you can see one of the many awesome property of water in this part: when it freezes, it releases heat and warm up and when it melts, it absorbs heat and cool down. that's why when the weather says that it will be 0°C (32°F) outside, not much happens: because when the water solidifies, it releases the heat that was captured in order to melt. it's a little bit far fetched, but it's similar to a property that allows AC units to move heat (phase change) :)

                                                Actually, thermal compound (in your case thermal paste) isn't a very good heat conductor. All it is designed to do is smooth out both surfaces for optimal contact under mounting pressure and that's what makes it cool better, since it does conduct heat better than air. But using too much thermal compound will have adverse effects on your cooling performance.

                                                  Why push air to heat sink? Why not pulling the heat from the heat sink instead?

                                                      Awesome! Try rigging those plates in a row, so that hot side of one is cooled by another and so on. Achieve a huuge temp difference by doing that?
