I conducted this experiment to see if I could produce electricity using the surplus heat from the wood stove.
1. Power Generation Module
I installed two thermoelectric elements that can be used stably even at a surface temperature of up to 250 degrees Celsius on the aluminum plate and connected them in series. And I installed computer CPU radiator and cooling fan for cooling. It is said that the greater the temperature difference between the both surface of the element, the more power they can produce.
2. Installation of Power Generation Module
I tried to generate power by installing the generation module vertically on the stove pipe. The module was brought into contact with the heat-absorbing surface at the appropriate height of the chimney that can use heat, and was fixed with a stainless steel band.
3. Power Generation Performance
I added firewood to the firebox and burned it to heat up the stove, and the chimney gradually became hot. The LED of the constant voltage module did not light up, but it was confirmed by the multimeter that electricity was produced. The voltage was lower than expected. I confirmed that the surface temperature of the stove pipe, which installed the first power module with a contact thermometer, was less than 100 degrees Celsius. So, the power generation module was installed at a lower level. The intensity of wood fires in the stove was increased and a cooling fan was operated to try to make a difference in temperature. Although it was possible to secure a voltage of up to 3.5 volts, it was far less than the target voltage of 6.5 volts for operating the system.
4. Conclusion, Improvements
There are two sides of the thermoelectric element, and the heating surface should absorb heat as much as possible within the endurance limit, and the surface to be cooled should be cooled as cold as possible. And the larger the temperature difference between the two sides, the higher the power is produced. It should be devised to maintain a large temperature difference between the thermoelectric elements.
Thank you for watching.
Always be safe and have a fun camping.
Stay safe.

This fire pit is one of a few covered pits that is on the list th-cam.com/users/postUgkxAU9pOCSV9Y5JprooHvfxTpOrt4hx8uRM of approved products for Disney Fort Wilderness. The product served its purpose well and provided excellent fires throughout the evening. We were able to open the door and do s'mores, but I had to be careful because the handle was a bit hot on occasions. Additionally, I wish they had replaced some of the standard nuts with lock nuts in some places. We lost the door handle after just a couple of days of usage. Not a deal breaker, just a recommendation. I still give it 5 stars.
It's nice to see power generation videos on TH-cam that don't lie. Excellent experimentation.
Thanks for watching😊
정말 캠핑투게더님의 아이디어는 어디까지인지 대단하십니다~
you also need thermal grease on the hot side of the chip as well , for the same reason as the cold side of the chip
Man, it keeps getting better! Kudos!
Hay que seguir investigando y probando!!!, Bien por vos!!!
Nice mate, I like it. Ive built a similar thing for a kerosene lantern and an alcohol stove. I had to run the hot side at at least 130 degrees to really get power running. The kero lantern could do it, but I needed a heatsink on the hot side as well to really suck up the heat. Worked out very sweet, light, and a phone charger!
One major bit of advice, you use tapped holes on both the heatsink and the mount. TEC’s, ive found, need to be clamped tight. Drill out the hot side, so your pulling the bolts down hard on the sinks. Full wrench hard. Crush them. I also didnt bolt directly to the heatsink, but a bar across it, with the heads out of the path of the heat. Dont want the bolts themselves to conduct heat from your hot to cold side.
I also found I needed to ‘bootstrap’ the fans, like you do. I just put a 9v battery (PP3) clip on the fans, so I could clip on a 9V battery. Then another PP3 clip across the TEC’s and charger circuit. Light the lamp, warm it up, attach the battery to the fans. Once everything is up to temp, about 6v, swap the fans from the batterys clip to the TEC. You need a starter battery, but it really was the ‘eureka’ moment for the project.
I’d also ditch the swanky LED display USB regulator. I used a very basic single cell LIPO charger with an 18650 holder. Super tolerant of wide input voltages, I tended to get between 4 and 6v, depending on ambient temp and load. And that charged 18650’s fine. Most of my load is geared to those cells, USB charger for my phone n tablet, torch, vape, tent lamps, all 18650’s. Keeps it efficient. To go from TEC voltage > 5v (with LEDs) > battery bank > 5v > usage , lots of loss. TEC voltage > 18650 > usage, really only the battery charging loss there.
Unfortunately, I wasn't using high temp TEC’s. My project came from another that used 6 TEC’s as a chiller, and the best price I got was from a pack of 10. so I had 4 for free. What else can I do with these? The kero one still lives, but I killed the rest on an alcohol stove, finding how hard can I run these? About 8v, 6W out, running the fans from the TEC. Then there is that horrible ceramic plink sound, and everything goes to 0. the kero lamp gets about 4w useful power to the batteries.
TL;DR Clamp your TEC's tight and isolated, and use direct battery charging. Your going to have a lantern or fire lit anyway, might as well use that heat!
TEG . No TEC . Por eso no funciona . Debe ser seebeck (TEG ) nunca peltier (TEC) error
👍👍👍 Yesterday I made a video of a mini thermoelectric generator on TEP1-142-T300. Your design is very interesting, a little grammatical, Thanks for the good video! 👍👍👍
I made a generator on 6 elements connected in series. I managed to reach 1000 mAh of 5 Volt with a load.
Hi. Thanks for watching. Check out my latest video of thermoelectric generator.
Great idea, the project gets better all the time😀
Try wiring the fans to the input side of the 5v converter instead of the output. The fans will activate at less than 5v and will provide an ever increasing temprature differential for the peltier junctions. They will just work better and better untill they produce 6+v and the converter kicks in and charges your battery bank. Just an option.
And Personal computer fans.. are far more efficient than the fan he used :) Even with a variable power switch built in.
Que no deben ser TEC (Term Electric Cooler) las que hay q instalar son TEG ( TERM ELECTRIC GENERATOR ) efecto seebeck . No peltier
@@marioschutrumpf9463 I think it's all the same principle. You can power it to make a cooler or you can use a thermal gradient to generate a current.
Whatever the case, I think you could optimize it by using the draft of the fire to draw cold air through or over the cold side of your TEG. You're mainly running that thing in the cold, and the outside air is an endless supply of cool/cold air. Too bad I'm not an engineer, or I would either build one, myself, or know it's a dumb idea. Wait. I can go on thinking what I want, if I don't do or test anything. I can hold on to that idea as long as I please, now! Cool!
I like your video because there's zero talking involved. You just show the work & let it speak for itself. Too many annoying ppl on youtube just blabbing.
Thanks for your support!
That was worth a subscription, thanks for sharing!
오늘도 대단하게 호기심을 일으키는 동영상이네요 잘보고갑니다
The genius of the human mind. Shame more people arent as constructive as this! Bravo Sir. Thank you for sharing.
As always you are a great craftsman
THIS IS SO MUCH COOLER THAN I HAD IMAGINED!!!! Great work! if you have some twists in the pipe. like a snake, does that give you more surface area to get heat from before it exists tent?
Brilliant ... your skill is professional level ! thank you for sharing
Great work! Keep it up! Now for those module you will want to use a boost converter or a sepic converter. They don't produce as high of a voltage then what they are rated for and also you can buy high temperature one that are rated for more power and 300c but they are expensive one. I made 2 of these as well using repurposed old one. They work to light up an LED but nothing fancy for charging they need a lot of heat. Cheers!
Thanks! I will try different way maybe one or two more shots.:D
@@campingtogether if you need help let me know!
멋진 아이디어와 프로젝트네요!! 저도 아이들과 우드스토브 만들기 프로젝트를 시작해봐야 겠습다^^
Love your channel. Great stuff. Great ideas thanks
Love your videos. Never give up trying.
you surprise us every time. that is what we need in these difficult times keep your distance and stay safe.👍
SUPER IDEA . POZDRAWIAM . POLSKA .
Having power is like the cherry on to. I'd be happy with it just being warm.
👍👌👍
Great work and like your continuous improvement
Thanks!
Wow
I actually learned something
Thanks man🙂
I think thermoelectric elements work better at higher temperature variables. Maybe you can ice the cold side to see if camping in the snow and moving the radiators outside with ice water being pumped into the tent through insulated tubing to a copper heat exchanger on top of the thermoelectric elements would be an improvement. But what would circulate the water? Another need for energy? What about thermally inducing the flow? I see a lot of people doing that to make hot water. No pump, just temperature variables moving the water. One other thing I was thinking, maybe the radiator you're using can be better. The ones you're using are for taking the high temp off processors, supper HOT! I think if you got your temp colder you're going to find better results. I really like the way you think! And you're mechanically inclined enough to do some really nice work!
Using water pipes heatsink away from the stove would be rather better, no noise, no power output problems.
Сначала снял крепление, а потом такой, блин, надо же башни как то закрепить 😆👍🔥
Non ti arrendere, sei molto preciso e certamente riuscirai👍👍👍👍👍
Guarda il video del prodotto di miglioramento che utilizza il metodo di raffreddamento ad acqua. Grazie.
Amazing video 👍 Thank you ❤️ God bless you and your family ❣️🙏
I'm a new sub 😁
Looks like a awsome little wood stove.
Habe mir das gleich für mein Raketenofen gebaut , bloß mit mehr Elementen. Viel Erfolg noch 😁👌
Hallo Benno,
wieviel Ampere lassen sich bei deiner Bauweise mit mehreren Elementen rausholen?
능력자이십니다!....나중에 더좋은 결과있가를 기원합니다.
감사합니다. 좀 더 살펴보겠습니다.
IMHO this CPU coolers using heat pipes should stand upright for best performance. Cool video. Thanks!
실험정신 대단하십니다. ^^
Я тоже тестровал эти Пельте. Эфективность низкая. И ты используешь электричество для вентиляторов чтобы их охладить больше чем они дадут электричества ))) А идея отличная !!
Woo thats is expensive project. May it great when winter
Double les modules Peltier en série et tu doubleras ton voltage . Très intéressant. Si tu développe un modèle 12v ou 24v performant tu vas trouver des clients !! 👍🏻
Ciao! 🇮🇪
Beh.. Son passati circa 40 anni quando giocavo con le Peltier.
Cmq potevi fare un raffreddamento ad acqua.
Sicuramente il risultato era migliore ottenendo il vero potenziale reale a causa dello scambio termico rivelato dal sandwich dei semiconduttori interni alla Peltier.
Infatti, più raffreddi il lato freddo in questo caso meglio sarà la risoluzione nella potenza.
E questo vale anche per il lato caldo,
Se la cella la usi per un eventuale frigo.
Nel frigo più raffreddi il lato caldo più precipita la temperatura oltre i 25° sotto zero il lato freddo.
Quindi il raffreddamento è estremamente importante per una buona efficienza anche in volt.
E dovresti sapere che le celle di Peltier se superano una certa temperatura nel lato caldo, si danneggiano irrimediabilmente.
Scusa se mi son permesso qualche suggerimento.
Ciao :)

Hi I had conducted a similar experiment many years ago with the first cells of Peltier and had had the same problem, in that case I used to cool a refrigerator but the physical principle is the same.
Along the two sides ceramic you don't have to create thermal bridges that can heat the "cold" side.
The system can be improved using a pressure cooker with a 1 cm thick bottom to work as a cold tank, you can use the steam output tube to pump cold water in the pot and with an additional tube withdraw hot water considering that hot water goes Always upwards the cold tube must send water directly to the bottom where you put the cells. I would put 4, 2 in series, 2 in parallel.
An alternative can instead be to position the cells on a thicker floor not connected to the exhaust fumes but on the rear panel of the stove so as to keep the heat away and use a steel heat exchanger, of those that are installed On normal gas boilers.
Given the efficiency of Peltier cells in their traditional operation I would use a Stirling generator for this application.
정말 대단하십니다-~
좋아요~
감사합니다. ^^
Bin gespannt auf den nächsten Teil 👍
I love it bro. I would love a community like that .hunters and gathering mad max sh## .you rock bro..can't wait to bug out .woooooooo
From a retired Navy electrician that is interesting. A 12 volt 5 amp output would be nice for what I have in mind.

good idea maybe improved with a duct insulated from the outside of the tent. greetings from Argentina
Good video production.
님은 다 계획이 계셨군요. 아름다운 마무리 기대하고 함께 하겠습니다
Thank you, sir, for posting your video.
I hope you were able to solve the problem to getting the voltage to the target strength, and will be looking through your channel with great interest to find out about it.
I adore your notification m8
오늘 아침 화목난로를 받고 깜놀했습니다

Good Upload 👌
If 2 TEM (Peltier) in series = 3.5 vDC, then 4 of them would be 7 vDC. Looks like 5 TEM in series is what you need. Also, the rising heat from the stove shouldn't be entering into cooling unit/radiator. Interesting experiment. It was fun to watch.
Thanks for your idea! I will try do more on this. Stay safe!
I was wondering about using these since taking apart a thermo electric cooler. If you put the unit outside the tent on the pipe and insulated the inside pipe (so more heat was up at top) would the outside air be good enough to not need fans?
Great suggestion. I will try various ways. Thanks!
참! 멋지게 사신다.
RAWR!!!! I thought you had it!!!!! Keep going, I am sure you can make it work!!
Yeah, keep going!
В СССР выпускали термоэлементы ещё до Великой Отечественной,они тянули ламповый переносной приёмник
Good stuff.
the peltier cell, what have you put it towards the heatsink of the cpu? the side that is hot or cold?
오호 발전기였다니 제 상상 그 이상을 생각하시는군요
생각하시는 이상의 성공이 계실거 같습니다.
곳 엄청 멋진 물건이 만들어 지겠네요
한 번 만들어 보고 싶었는데 쉽지는 않네요 ^^, 외국분들이 댓글로 링크를 주셨는데요, 이걸 실용화한 제품도 있네요. 앗 ㅎㅎㅎ 일단 충전 되도록 뭔가 더 해봐야겠습니다.
So what you need to do is stack them. Hot to cold side and run them in parallel. So long as you still have a hot and a cold side they will balance the heat out
Элементы Пеллетье надо напрямую на трубу устанавливать. Мне кажется слишком много тепловых переходов в твоей конструкции, друг. И ещё - я бы добавил экран между горячей и холодной сторонами устройства. Кулеры нагреваются восходящим горячим воздухом от печи.
Удачи тебе в экспериментах!
도전정신 만은 인정합니다~~^^
고맙습니다😊
Great! 😮 👍
Great idea...few things can be added..
1: Delta T is most important, If you keep colder side out of camping tent then it would increase its efficiency and power output, since hot environment inside camp is not allowing that Delta T..
2: Add exhaust duct flapper to constant the heat in duct..Normally 150°C should be enough for a good TE to perform at max..
3: Make Peltier contact flat to the duct.
Most importantly, wish you all the best..will appreciate to see further follow up till success..😁
Thanks for the idea. Stay safe!
Very nice work. Enjoy your videos.
I was watching you put the unit together and thought I saw a pc style fan between the radiators. But I did not see them being used. Perhaps the thermal power was to power them? That being said... in my opinion... then arnt you pulling heat from one rad and driving it into the other? Like transferring heat from one side to the other. Perhaps the fans should be placed on top and draw cooler air from the outside and through both rads. That being said... pushing air through is more positive than trying to draw air through. Just a thought. Nice work. Cheers.
Hi, Kevin. Thanks for your comment. I agree with your thoughts. However, the fan was unable to operate due to insufficient power. In the following video you can find a water cooled generator. Thank you.
Лайк и Удачи тебе...
legal , se aumentar a quantidade de elementos (peltier) gerara mais voltagem ?
겨울철에 쓰면 좋을것 같네요.
눈 뭉쳐다가 냉열판에 넣어두면 펜 돌릴 필요도 없겠어요.
겨울에 귤에 많이 나오니 구리판 꼽아서 귤한 500개 연결하는게 더 나을거같아요 까먹으면서
새벽에 이런 놀이는 너무 재미있습니다
Fantastic
Nice project try to use 4 or more Peltier module and rotate the heat sink 90° so hot air can rise above.
Would you be able to increase performance by having a second set of heatsinks on the inside of the pipe to better capture heat from the stove exhaust?
Great job. but how many amps?
Those are some serious heatsinks.
좋은 아이디어네요~~^^
생각보다 쉽지는 않네요. ^^
Severel years ago I've did similair progect ,while electricity was off.
It was interesting to see , how the 1W LED become more bright , while snow added to the cooling water.
Also I can say , that Indigirka stove produce 60 W of electric power .
I know that it is probably too late to give input for your project, but I'll try anyways. Make it even more complicated using a stirling engine lower down on the stove to provide air movement and turn the heatsinks 90 degrees to use the stirling engine's fan vertical exhaust for the cooling. The computer fans you have mounted are 12v monsters and do not help much for the power they draw. The stirling engine will use the heat of the stove passively and not put a load on the power system. Unfortunately, it may require separating the peltier units from being vertically stacked for optimal heatsink cooling and placing them at the same level will mean you need 2 stirling engines. Those engines are mostly used for powering campstove fans in cabins, so not much work will likely be needed to fit them in to your project.
Thanks for this clear experiment - but voltage only is meaningless : how many Amps did you get ?
Also the fan might use more energy than what is produced - A low flow of water could be more efficient and cheaper to build
The chart giving the power vs temperature of the pelletier module is very hard to find ; usually the chart we can find gives the performance for cooling purposes
Anyway congratulations for this construction
Hi, Thanks for watching! Stay tuned. Another experiment on this coming soon.
superb
Tankou desde Brasil💪💯✔✔🔌
Way cool, nobody else thought of it ...great job!
Thanks Scott!
if you are using a heater. why isnt this thing installed outside the tent where it is naturally cold?
Vera e pura opera ingegneristicha bravo👍👍
Grazie! Questo è molto divertente.
Why did you remove the coolers fans.?
I love tec's and teg's but they aren't the best in efficiency but I would probably use 4, 6, or 8 for the power bank use led's for lighting straight to the teg that would work and be useful otherwise get more to get the voltage to where u want it but the mah output isn't great with 6 teg's 2 parallel and 3 in series should work 8 teg's (2p4s) would probably have the best chance
nice video
Gut 👍
dont use the aluminium base, its disipating heat before producing electricity. u have a new suscriber
Sweet
Buena explicación, había cosas que no sabía,ñ.
뭔지모르겠지만 신기하네요ㅋㅋ

질기더라구요. 잘 안잘려서 팍팍 잘랐네요. 조심하겠습니다.^^
one little thing to maybe help boost the input, not fully, is to spin that 90 degrees behind the stove. heat is rising from the stove onto the cooling side a bit.
Highly recommend thermal paste between the aluminum mount and the thermal chip and not just between the thermal chip and the heat sink.
I guess that was the main problem - both surfaces of the peltier element must have good thermal contact.
펠티에소자를 늘리거나 승압을 해주거나 선풍기를 이용해 온도차를 만드는건 배보다 배꼽인 상황이죠
Is it possible to have a much wider module peltier ?
Great project but breaking thermal barrier with the four fixing screws, they transfer heat to the cooler. a piece of 25mm square bar the length of the channel, and basically clamp everything together.. the greater the differential the better the power output... good work.
Hi Aiden! Thanks for watching! After I found its inefficiency, I modified all these installed with water cooling module and it worked great! Check the video out. th-cam.com/video/H0Qva6JxSD0/w-d-xo.html
@@campingtogether Hi im working on similar project, have been for last couple of years, cant give too much away... i thought about putting, the pc heatsinks in a tube, fan on the intake so cooler air, have so clip onto flu pipe. and have a flexiible pipe off the outlet to another area. blown warm,dry! air!... but what i was on about was that using four screws, they are tranfering a lot of heat to the heat sink. by putting a piece of box section behind the heat pad of the heat sink, and three fixings one either end and one in middle. the heat will transfer to the box section first, aluminium woud be good as disapate the heat!... like your work..
