I was doing a test for each solar module on a solar panel you put on the backside with this Peletier,only generated 0.7 volts under hot conditions I only used one Peltier for one module, so 0.7×24
It can overheat and break, so normally they are on a conductive base with a bi metallic strip underneath to lift it if the base gets too hot, if you had the chip flush it would be difficult to control the heat using this method
If I was to use 2 of the cells what the big heat sank and a super-efficient fand I put black tape on the hot side and pointed at toward the sun. Could I charge a phone
There are 2 main problems, first, Thermoelectric Generators have max. 8% efficient in converting heat into electricity, and second, the greater the difference in temperature between the hot side and cold side, the greater the electrical power produced. For example if heat difference of hot side and cold side is around 10C, peltier will produce miliwatts. It will be too low to charge your phone. If you want to use sun as heat source, you need to set lots of peltier.
the cool side/top side of the stove device has a huge heatsink that radiates heat away from the cool side. But I bet if you would heat it up the fan would stop yeah
I think thermo cycling actually cools down a hot surface. So, cooling fins with wires that cycle electric current, would cool better than fins alone. So you could have a machine gun that uses heat to power a red dot sight, or a digital dashboard powered by the heat from exhaust gasses. Which is what a catalytic converter does.. kinda
Nope, their source of electricity is radioactive decay of plutonium. We can use Seebeck effect to generate electricity if there is significant heat difference at the same time.
There has to be a big difference in temperature between the base and the upper part for electricity to be produced. On a hot day the temperature would be fairly equal between the top and bottom of the fan, it needs a big difference in temperature to work.
Yeah, but HOW does the N and P semi-conductors generate power from temperature differential? You are only showing the result of the phenomenon, not the reason. Good grief!
Nah this shit doesn’t work enough, i use an electrical fan on the back of the room, pushing air in direction of the stove, forcing air circulation, blowing cold air to the stove forces the hot air around the stove to move away from it, creating a heat balance. Hot air goes up and cold air goes down but also each particle of air cannot occupy same place
we have a stove fan and my mind was blown by the simple technology thank you for this explanation
crazy to think that if you showed this fan to someone 100 years ago theyd think its magical. humans are so cool
great explanation. simple and direct.
so fascinating , never knew you could generate electricity directly by fire
What you don't know could fill a warehouse.
@@M.Lynchianquite the compliment.
Not by fire, by heat
Nice! I was wondering how they worked, as they seem kind of mystical at first, lol.

Could a big enough one set on top of the stove power something larger than a fan 🤔
It only generates a very tiny amount of power, typically only a few milivolts.
so what does it mens why it does not blow as good as it did in the beginning?
1:11 Wouldn't the Peltier chip rather be in the wide base at the bottom where the heat is?

If I put it on the stove and it gets too hot, so that both sides of the cell are about the same temp, will it stop generating electricity?

I get the gist of it, thanks 😊
Does Mars rover uses this effect to Generate power?
Nope, their source of electricity is radioactive decay of plutonium. We can use Seebeck effect to generate electricity if there is significant heat difference at the same time.
How come we dont use these to power most of our electronics on hot days?

Yeah, but HOW does the N and P semi-conductors generate power from temperature differential? You are only showing the result of the phenomenon, not the reason. Good grief!
As a result of emission or movement of electrons from the N type semiconductor to the P type semiconductor
I want a huge peltier cell now
Based Peltier discovery 🍷🗿
You could use a Peltier cell to make electricity, so the fan could try to power istelf, after the stove heats up. Just mention me if that works :)
In someone else's house trying to get the fire going and I can't figure out how the fck it works.
