Ryan Willis: I correct myself: a candle puts out a whopping 13 lumens. Still only an efficiency of 0.16 lumens per watt. Modern LEDs are capable of 150 lumens per watt or better.
Ryan Willis: That is the problem with these things, they almost always put out less than 5 volts so it's hard to do anything with the power they generate. I'm planning on making a version of the device in the video but using a dc-to-dc step up converter to power a single 1-3 watt LED with it. Send me a PM and I'll give you a link to what I'm going to use.
George Louis: I ordered some of these from China. (that's the only place that makes them) So when I get it how do I plug it in?
Ryan Willis: I meant an electrical meter, one that can measure volts and amps and whatnot. You are correct: if you heat and cool the "wrong" sides, the electricity will just go the other way so black will be positive and red will be negative.
George Louis: What the hecks a meter? You mean that if I heat the other side then the electrons will flow in the opposite direction and it doesn't matter if the electrons are going forwards or backwards?
Ryan Willis: It doesn't really matter- if you heat the wrong side you will get the opposite polarity on the wires and that's all. Just measure with a meter before you hook stuff up.
Ryan Willis: if you can convert 2% of the heat generated from a candle (candle makes 70-80 watts and one lumen) to electricity, you can power a 1.5-watt LED which will make 80-150 lumens. Candles are really not efficient light sources.
Chad Harrington: Something mirrors could also do... for allot less money :)
George Louis: what is the difference between the two sides and which side has to be heated and which side has to be cooled to generate electricity?
Larskro: You can apply Materialer as du need on "ebay.com ``
imtiyaz ahmad: sir how i can make this peltier systm,plz help me
cmlundin: You could also build a voltage multiplier circuit. You will loose amps, but it does bump the voltage up to a usable level.
cmlundin: a small amount of electricity is diverted to power the fan from the thermal
brian burnett: this Is No Fake. , just Normal test. Far out. yeah alll true.
brian burnett: Yes Very Small power supply ,,isnt it. i got a dozen and still think its a waist of time Now after testing One, but when i get the full 18 units of 40 mm High Temp TEG Very Soon ,So I hope i can Get good Amps on my test. With Yours Im Wondring the Top Vltage and Amps. Have you Cheaked.
restu pamungkas: Good job. Is reall experiment
Lodoz: Why do idiots keep posting these stupid fake videos?
Larskro: Hej There is not a battery in the phone charger. See the wire going in.
Yefatbastard: The man with the million dollar question.. I was not there to see his setup.. but based on his comments on the power output of his TEC/TEG and that the fan was running before he even puts the candle under the chimney, I would say it's the battery in the "blue converter" I would ask the poster to show the setup again with a look in the blue bit included.. If the poster deletes this I will have my answer and will send it to you in a message.
