PELTIER THERMOELECTRIC COOLER Campfire Electricity
February9
This is a video showing one possible concept to using tecs for solar or camping. This could easily be designed to charge small devices with coals from a campfire or the fire itself.
hmm correct me if i am wrong but woulndt you get more energy from the peltiers if you changed the water in the pan every once in a while, so the temperature difference would be maintained, or maybe used a coolant fluid or something?
it is pronounced -ier, it would take an acute accent on the e for the ending to sounds ee-ay
This current peltiers have an efficiency of around 4%. The cost of these things are high. It makes a nice gadget, but never a good way to make electricity. Too bad. Maybe in the future someone finds better materials, but it doesnt look too good. The research is kind of stuck
Peltier,I don’t suppose Mr Peltier would like you mis-pronouncing his name,brush up on your French and pronounce it properly,Pel-tee-ay.
I can’t wait to use this technique winter camping! Great video.
what is the voltage and the amps that the heat pump is rated at
liquid cool the other side and the voltage should go up add another peltier so run the cooler look up computer peltier coolers.. they are liquid cooling the hot side and chilling the other to over clock computers.
Data for 2 I found:

TEG1-12610-5.1
Open circuit voltage: 8.6volts
Internal resistance: 3 Ohm
Match load output voltage: 4.2V
Match load output current: 1.4A
Match load output power: 5.9W
HT1-12710

stove 200 deg C Peltier is producing 6 v open circuit.
1 bulb 6.2v at 140mA. With a 500mA bulb the voltage dropped to 3.5v and 300mA.
Graph of temperature versus efficiency.
180 dgrees centrigrade is best.

had a commentary about watts/volts/amps for various TEC modules.
I’m trying to make an ecofan using these devices. I want to put 3 small 12v fans pointed in various directions. Would I need a heatsink sitting between the Peltiers and the aluminum base? And should I run each fan with a separate fan? Thanks for any help.
you have to be careful because aluminum powder can explode if not handled correctly.
omg … have you lost your mind?
Great video, learned alot. Just would have liked to see the peltier’s setup between the two pans as you made it. But either way, thanks for the vid!
You mentioned you wanted thermal glue instead of thermal grease. I have a solution which i’ve used with my own peltier experiments several times. Get some lab quality finely powdered aluminum. It should be like dust not sand. FINE POWDER! I got 2 pounds of it off ebay for cheap. Mix it with 10min epoxy until you get the consistancy and same solid grey color as thermal grease. Problem solved! It’s MUCH cheaper than buying premade thermal glue and it works very well. Just wear a dust mask!!!
Cool, I have a few of those peltier units that I have been playing with.
Yes it would. The problem is more temperature difference, more current. It is easy to get +300f but difficult to get -300f.

I like this Idea- but have a question. Electricity makes it produce a hot side and cold side so you reverse it by putting heat to it generates electricity I get that part now if you were to try cooling the otherside instead of using heat- like putting it in the snow or on some dry ice would it also produce electricity? Or is it only the heat that produces the electricity?
