I saw this amazing heat electrical fan which works using the heat from the stove to cause electrons to be excited so that they can flow between two types of silicon semiconductor.
This is pretty much the same as a Photovoltaic cell, a diode or a transistor works.

Fascinating? It's fucking magic
Lols!
Science nerds are just afraid to admit that it runs by magic.
Help If you turned the tv down
we can hear your tv/radio.
Good God man! One at a time, please
It is a peltier w/ a seebeck effect
Could you put it on an induction hotplate directly, or on an induction hotplate diffuser?
Not sure about induction, I'm not sure if the base is metal or ceramic. But might work. Any heat source should do it.
Works on ceramic hot plate
Is it a Peltier
Yeah, that intro makes the video look super amateur. the shaky camera, the blurry images, and someone else talking in the background. I nearly switched off after ten seconds
So what’s the lowest heat temperature that will start that motor to turn the fan and if you introduced a freezing a lower temperature of frozen essentially negative then with the fan start at a lower heat
These are excellent questions. Can't test this, as the fan isn't mine.
But yes I think you are right, if you had a bigger difference in temperature, I think your see a bigger potential difference (voltage) and so a faster motor.
Just got one of these as a gift. Fan started turning when the base hit about 65°C. Room was 16°C, but I'm sure it was warmer at top side of the fan
The cheapo fan I have starts when the surface it’s sitting on reaches 60*C - regardless of ambient temperature. My stovetop reaches that temperature very quickly (
I have a stovefan....was wondering if there was a way to increase the temp difference between bottom and top of the peltier , and if so, woould it make a noticeable difference on amount of air the fan blows out ? For example, I was thinking about adding a containment system for the very top of the aluminum heat sinks, to allow me to fill it with water, which should create a bigger temp difference ?
if the water circulated around (like in a radiator), then it will make the fan turn faster. If not, the initial warming of the top will take longer, so the initial thermal difference might be a little higher, but once the water is warm, then it will probably be warmer than the fresh air entering the fan, and will actually lower the differential.
You could but a aluminum tray or bowl, and put ice cube in them. Once it's all melted and the water is room temperature, take it off. That would help initially.
The very first explanation that I can understand well I understand the bits I can hear, Maybe you could gag that blade shouting over you!!!!!
Awesome video! I was just wondering is this really GCSE and A level physics? I only learned about semiconductors and p and n type doping in college
You know it was in the pre 2015 specs, but not all of them. Probably comes up just in some A Levels now.
How is it the silicon doesn't run out of electrons?
As it's a complete circuit they are essentially replaced by electrons in the other components. Kirchhoff's law of conservation of charge!
@@KitBetts-Masters Does this mean that the least noble metal in the circuit is slowly corroding?
Peltier module
what brand is that wood stove?
So, is it a Peltier?
Not sure what one of those is sorry!
yes, it's simply a peltier junction with a huge heat sink to remove the heat from the top. really easy to build. just figure out the output voltage and add a motor accordingly. ua-cam.com/video/ML0JQENP6IQ/v-deo.html and ua-cam.com/video/Ipm77mhiwSg/v-deo.html
Yes, it's Peltier.
Unless there is some other kind of semi conductor technology that competes with Peltier that I have never heard of.
But all I know of is Peltier.
Two people speaking sometimes at same time with TV sound in the background make it difficult to watch and listen to this video.
Must not have made it past the first 30
Seconds
I made it by myself thanks to woodprix plans. I think it's the best way to learn how to build.
Rubbish, why not tell the truth. IT'S MAGIC.
