    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)

      Could someone give me some advice here? I powered one of these with a 12v/2A power supply but it killed the power supply. At first it worked, but after some time the power supply got very hot and it's voltage output dropped by more than half.
      Anyone know why this is, and how to resolve that?

      To note, the hot side was being cooled with a water cooling setup which was very efficiently keeping it nice and cool, so it was working well aside from the fact the power supply died...

                How it works on atomic / quantum level?
                I can imagine situation as follow. The flat surface with current connected to opposite sides of the surface causes the flow of electrons. But due to the shape of the surface, the electrons create circular current movement - as in the coil. This circular movement also causes the magnetic field to "move" as in the coli perpendicular to the axis of the circular current. But what is different, that in the coil you don't have any obstacle on the way of the magnetic field (the interior of the coil is empty). Here you have the surface which is affected by magnetic field.
                Here are only my imagination further: the magnetic field slows down the frequency of the electromagnetic radiation of the surface (cooling) on one side and speeds up the frequency of radiation on the other side (heating). I can imagine this as an item positioned in the wind - it will get cooler faster because the "wind" is taking the energy from the obstacle. In case of your experiment, the "wind" is the magnetic field. And the energy is given back on the opposite (heating) side of the obstacle.

                Probably this could be proven experimentally by placing the same shape in the middle of the coil. If it cools down and heats up then this is the case.

                Please let me know what you think about it :)

                        If you didn't have a power supply would you buy my kit for $85 and you will have to make the holes for the electronics and soder it together or premade for $100 480w output at 0 to 32 volts 0 to 15 amp

                              Omg this thing is very inefficient, over half of the power is turned into heat and the rest is a bit freezing. Okay I'm only kidding, so if you're in cold space the freezing side is probably very cold

                                                    Peltier elements are great if a compressor is too big. For any other usecase they are useless and just use a bunch of current for no benefit or even worse results.

While the peltier devic, instead of housed in heatsinks the peltier device warms up a jacketif the jacket is filled with oobleck and its vaccumed sealled when it heats up it will expand and make a poofy parka.....I dont know if it would be bullet proof. i was wondering just the peltier device alteranting power to different thermocouplers so some heat the cold ones while messing with the natural output.So heat side touching cold side. and some small fan to blow heat in the jacket. im sure this makes no sense but im sure your talking to kids so you will understand my child like jibberish.

                                                                                        so if i wanted to cool something that normally i can only cool to 30c with water cooling. then i could use this, cool it to 30c and use the temperature difference to get the temperature lower?

                                                                                                I'm currently researching the better options for a heat-engine to use Concentrated Solar Power (from a mirror dish) and generate electricity, and I stumbled on these devices.
                                                                                                Quickly found that they're really inefficient so I dropped it (currently looking how to optimize a Stirling engine).
                                                                                                But the idea still got nested somewhere in my brain I guess ... if efficient no-moving-parts components can do the job they have the potential to be better than mechanical devices ... if only :)
                                                                                                So I wonder does anyone know what are the main factors for these thermo-electric devices inefficiency?
