DIY Peltier Candle Powered Electric Generator

I used a Peltier cooler and a candle to generate electricity. To learn more about peltier coolers see my other Youtube videos or visit http://filear.com/?cat=48

A thermoelectric device has two different semiconductors alliteratively stacked and connected kind of like little blocks. When current flows through one conductor it will make heat and the other slower conductor it will cool (the Peltier effect) . It is not easy to explain so please visit these links. http://en.wikipedia.org/wiki/Thermoelectric_effect http://ixbtlabs.com/articles/peltiercoolers/ They may help a little.

why you are coling heatsink with fan?

[filear]

@Slovenija12345 the more you cool the more current and voltage you can generate. That heat synch is inadequate.

You mentioned that the voltage jumped up when you turned the fan off, but I am still a little confused since their was no load applied when you removed the fan... Although my question seems like it would violate the 1st or 2nd law of thermo I am still very curious... obviously the fan increases the power output if you were to get power from an external source, but would it "pay for itself" (by increasing the net power output of the TEG) if you used the TEGs to power it?

@cxaxnxexs Well when the load was removed the voltage jumped up, its like when starting a car the battery voltage will be lower than 12 volts like 10 because of the draw, then remove the load and the voltage returns.

How does the generator get energy just by heat??

@flightdeckreviews I added some links to my video information above, check them out to learn a little about the Peltier Effect. (I can't add links in comments)

are these 12V PELTIER plates? I am looking at 12V 130W plates and i'm wondering how many i would need to generate 14V when sandwiched between out pot belly and the pot of water that sits above, i would make an aluminium sandwich they could sit in in-between the fire and the pot. Thanks.

400 milliwatts, you should try powering a laser

This is a great video.

Who wants free energy?

Cheaper electric bills?

In case you are curious, I am trying to build a high power density device that will output around 15-90 W (depending on size constraints)... I am trying to figure out if I can get more power density (in terms of power output per unit volume -- the volume would include the heat sinks and everything) by using some of the TEGs' power output to power a fan. My alternative cooling methods are (1) using only fins, (2) using fins and blowing CO2 from a compressed tank to cool the fins

try a bit less thermal grease next time! ;D
