🔥Another theory video. See my explination of how the thermoelectric effect works. See the physics behind this process and how a thermocouple and Peltier Cell works and what we have inside.
Important: I've made some serious mistakes and badly expressed myself in some cases. 1. When we heat materials, metal is a good conduction of heat as I tell in the video. 2. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. Particles, not electrons as I show in the heated glass pots example. Second, these molecules then bump into nearby particles and transfer their energy to them, those energized electrons. 3. In the potential animation, electrons should flow from V- to V+. What I actually showed in the video was the current path. 4. So, as I tell in the video, when we heat the metal, the PARTICLES vibrate more and the free electrons will simulate getting more separated on the hot side and more pushed together on the cold side. That creates a small voltage difference. Sorry for any other errors if there are. I'll try to update my errors the best I can. Have a nice day ☺️

Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. Particles, NOT electrons as I show in the heated glass pots example. Molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases, that's what I meant on the "voltage difference" creation animation. 3. In the potential animation, electrons should flow from V- to V+. What I actually showed in the video was the current path. 4. So, as I tell in the video, when we heat the metal, the PARTICLES vibrate more and the free electrons will simulate getting more separated on the hot side and more pushed together on the cold side.

Also, the statement that in absolute zero particles are not moving is wrong. At absolute zero, particles have the *lowest* energy possible.

You are a true scientist because you admit & correct the mistake you made. Mistakes are no problem (I do it all the time - oh, my..) as long as you correct them ASAP - preferably before "magic smoke" starts to ooze outta your (expensive) electronic equipment.. Aww - bad..! And yep, I have a very nice day - because of your wonderful explanation and very nice video. Hope you have a nice time too and thank you ! ❤😊😊❤

I have a question. If you have a circuit running using the seeback effect, you are pushing electrons from one metal to the other. It sounds like you will eventually end up with a low concentration of electrons in one metal, and a high concentration of electrons in the other - sort of like how a battery discharges. Is this true? If not, how? And if it is, does that mean that thermoelectric generators using the seeback effect can only go for so long, or can the electrons flow back from high concentration to low like a rechargeable battery?

Just for other viewer's sake, for his self-disabuse point 3, what he showed in the animation is NOT the current path, but electron path. Electrons flowing from V- to V+ is correct only at the outside part of the battery/voltage source, but within the battery, electrons flow from V+ to V-, and the seebeck wires as he showed is the battery itself, which uses thermal energy to drive the electrons to OVERCOME the electrical field internally and flow, which is why it's called a source. Also for his point 2, I guess it's more correct to use the energy increase and more vibration of Electrons that leads to electron density disparity, other than the Atoms as a whole, to explain the voltage formation, because the atom density difference on two ends won't form a voltage because atom as a whole is neutral, so I think it just is the electron itself that got more energy and drift to the cold end that forms the voltage over the two ends. Having commented this much, I have to say his video is awesome, and I learned the key knowledge from it and highly appreciate it.

I just ordered some "one wire digital thermometers" this morning, and look forward to playing with temperature control. I think that an incubator with temperature and humidity control might be fun, throwing maybe an ultrasonic mister into the mix along with some BME280 sensors.

Electrons bouncing around is not temperature, if atoms bound together bounce around slowly/gently something is cold. If atoms bounce around violently something is hot. If the atoms bounce so violently the bonds can’t hold the substance together, it is called vaporization/evaporation. If atoms lose energy and the bonds between atoms is stronger than the energy an individual atoms has the substance solidifies/freezes/condenses. It’s called Kinetic Molecular theory and it’s very important. Bouncing electrons against atoms can cause molecules to also bounce (like bouncing a small rubber ball against a larger one), resulting in the substance getting hot, but they movement of electrons is not actually heat

Great visual presentation. Don't worry if it wasn't perfect scientifically, you grasped the main meaning and the way to make it "visible"---in fact, able to be visualised. Yes, if we enter deep into theory electrons are not even dots but waves etc., the model would fit the theory perfectly in rarefied gases where the electrons would be the atoms--the ions, in fact!, and they won't collide with each other, but this is fine as it is. I did subscribe. Keep up the fine work !

Is it possible to create a type of circuit where the thermocouple generates a potential that drives a Peltier, and then the thermic differential of the Peltier provides the heat difference required by the thermocouple? I'd imagine that the size of the thermocouple would have to be very large in proportion to the Peltier, but what use could such a circuit have? I know perpetual motion is considered impossible, but could you have a closed loop that would only require a small external heat source to drive the internal loop? I wish I knew more about the physics of such things, but that's why I'm grateful to Electronoobs for creating such videos as this! I'd love to hear what potential uses and practicalities such a device might have!

Here are some thoughts. So the less dense elements and the more dense conductive elements have a stark contrast in electron output. What if we went more extreme? For instance, Aluminum paired with something as simple as lead or bismuth? Even in a liquid state the lead/bismuth would have contact with Aluminum. Aluminum = 13 CU = 29. This grants us a 2.23 electron output before Ohms. Al has 13 electrons while Lead has and Atomic number of 82. A possible 6.31 electron output. Low melting point problem. Tungsten would also work in contact with AL. 74/13. You wouldn't have the melting point. 5.69 output You would likely have a galvanic corrosion problem. :/ The more massive metal steals electrons from the inferior metal and releases hydroxides causing corrosion. OH- Conclusion: The corrosion is likely the reason this power system is limited to small uses like Thermal Couplers. What are your thoughts?

@6'40" should replace "electrons" word by CHARGE. Current is not due to "electrons" "moving", but charges (quanta of the electric field energy). The electrons are the media the charges "move" through. They're carriers of energy as much as antenas are carriers for radio (electromagnetic) waves (and antennas don't go walking from one city to another to "carry" the electromag energy to there....)

Ive been trying to figure out how to pull electricity from heat for years, so its just a wore around a cooling fin, that also contacts the hot part, which moves electromagnetic particles through the wire. So the negative would be where the cool part comes off, and the positive would be where the hot part comes off. Or opposite. Not sure. Extremely simple wow
