PELTIER THERMOELECTRIC COOLER Campfire Electricity

[dexterquincy1]

what a waste of 2 good cast iron pans. lol

[TheFarmerGraham]

i love it!

[vcentuba]

Great stuff dude!!! I've been seen your videos and your contribution is amazing. In last scene, you could put something more visible than a pinion on the motor. I'm trying to develop a generator with peltier, but for solar energy. Trying to cool my room, cause i live in Brazil, and here is hot! A lot of people spent lots of electricity in Air Conditioner (cooler). What do you think about to use the heat from the sun to cool it back??? :D

[LOPEZdJUNGLIST]

HI IM YOUR HOST dAN ROHASS .....

[TolgaCakiroglu]

Great video. Especially showing them while in working in normal environment is very good for understanding.

[coltesgaming]

try jb weld it holds up at high heat and it bonds and dries yeah its a bit messy but well worth it and great video very informational

[JonDeth]

Peltiers perform much better with a power cap on them in my experience. They're far more efficient for heating/cooling than given credit for. From what I have witnessed, a lot of peltier devices are engineered by ignoramuses that merely have the finances and college contacts to get their POS on the commerce market. They're not actual engineers/craftsman.

This device has a lot better to offer!

[TheSaltysack]

hey dan i got an ideal get a few of these then get a torch heat these babies up and you got free energy exept that you puting in some gas but its still free energy at the cost of nothing

[pfaffman100]

Dan, why don't you use a fresnel focused on the pan. Thanks.

[robertxtm]

how about making a perpetual motor using heat and the peltier?

[wevenhuis]

Hello Dan, Nice video. I want to try an idea to stick a peltier cooler to my radiator and put a small computer fan on top to spread the heat more actively in the home. At a temeperature of 30-40 degrees celcius do you know which capacity peltier is best to buy to run a 5-15 Volt fan? Or formulated differently, what capacity could I get to run a peltier cooler against a heater of 30-40 degrees celcius (in terms of amperage or voltage)? Thanks!

[leerman22]

can peltier coolers be made into panels? we can have one side painted black to absorb heat better and the other side cooled by water to reduce your water heater usage

[ajofscott]

Published max op temperature is 175C way below the solder melt point. What happens is copper diffusion through the solders and the copper busswork on the alumina into the Bismuth Telluride elements. A better approach would be the skillet sitting on a wet sand bed and hot coals placed in the upper skillet. Water is also lethally detrimental to a thermocooler. Any cooler should be sealed with silicone along all 4 sides to prevent moisure issues.

[climbingtothetop]

I wonder if you you take a few to power one?

[fernandesilyt]

How much you can warm this before melt or broke?

[irritatedbunny]

@fernandesilyt about 338 F, or 170 C.

[dpow86]

Would you be able to hook up a decent sized heat sink/fan combo to the peltiers to keep one side on a constant cool, with a small heat source to improve power production with a minor draw?

[SirPlankton]

too bad those things are extremely inefficient... for max power output a conventional diesel powered generator is more efficient than those peltier units. its just that the control of heat radiation is impossible, getting these things to run at a few % efficiency. Comparing that to a standard otto cycle engine which outputs approx 30% efficiency... It's a good concept of harvesting heat from unsed embers for example, but you could do better for powering electronic items

[fabulouswailer]

fantastic application of the concept! I have always thought there must be a realistic way of applying the heat of a campfire into a generator and this looks like the one!

[Olminar]

but what if you put one side(the cold one) in a small river? and ON the other side you make a campfire?

[truvak]

Dan, can you send me please the links for the other videos related to thermoelectric an Peltier effect please? Thanks

[KdrummerK]

you could also get a bigger pan and build a fire in it to generate heat

[MrCpuclocker]

I would set up  enough TEC to get 12 volts.Then hook that up to an inverter to get an ac outlet.

[josephdupont]

So how much temp can these units take???

[rammstefani]

This would be great to light up Africa. In rural areas people use biomass fires. After cooking they can just dump their TEC-unit into the smoldering fire, and light their home. A few LEDs will suffice...

[steveq34]

can you give me the specs on the motor please?

[SolarTrinkets]

hey dan, just incase you were still looking for some thermal grease alternatives i found this which might be usefull.. dealextreme . com / details . dx/sku.35819

[GREENPOWERSCIENCE]

@SolarTrinkets THANK YOU

[mojokiss]

20 people would rather have fried eggs

[superdau]

I wouldn't recommend using fire. As you stated wires will desolder if it gets too hot. But not only that. The small elements inside are soldered together with a very low melting solder. Except for some specially designed Peltiers even 100°C can already be too much!

[MrFreddyFeatures]

Won't the bolts allow the heat to take a detour and avoid the peltier,

I mean your gonna lose the heat difference if it flows to the cold side throught the bolts

[danielvincentkelley]

That's your most brilliant video yet Dan.

[philaheen]

I enjoy your videos, but it is a crime in my book to destroy cast iron. Why couldn't you use scrap steel plate.

[russotragik]

this is what you do when you don't have no one to fuck...

man, you need a girl, seriously =p

huahuuhauhahuuahuahhauhahuauha­hahhuahauhuhahuauhuhauhauhuhau­hauhauh

[JULYINJULY]

@russotragik Ummm douche bag, look at his other videos, his WIFE is 10 times hotter than anything you have ever tapped. LOL

watch?v=aJ22QCAqFCc

[russotragik]

@JULYINJULY i already have watched that video before, i was just kidding...

my friends used to say this kinda of things, when i make some electronic "garbage",

so i get this habit, and when i see something brillant or really interesting, i say things like:

"gonna get a life", "you do need a wife", "he don't have a girl", "she need a big d**k"...

do you got it?

[FrankCashio]

pretty light on the science. ♠

[earthwaves000]

Great video I looked on e-bay they have tons of peltier coolers... what size Watt,,,volts amps did you use..Thanks AJ...

[moscowfragfest]

Series of bolts or bolts in parallel?

[donkey2793]

i have seen someone get 14v from 2 peltiers

[demofactory]

I really enjoy your videos. All of them are well thought out and very informative. Hope you don't mind, but I use your videos to get my nephew interested in science. So far, so good. Thanks!!!!!!!!!!

[GREENPOWERSCIENCE]

@demofactory Thank you for sharing an teaching:-)

[Surannhealz]

Very cool concept, and good explanation both verbally and visually.

[vatrenikrug]

great videos...

thanks so much in the name of earth :)

[cusanusnicolas]

Yeah, okay, but the fresnel lens may well melt the pan, huh? Okay, maybe not, but if not it will still get extremely hot, great power potential, but how well are those little silicon crackers in the middle going to hold up? I like the idea, but there's a LOT of unknowns here, and no salesman is going to warn you.

[masluxx]

ground water 70deg pumped up then, split into 2 pipes, pipe1 to roof for water heating. The other ,pipe2, flows into a swampcooler type unit to produce cool air(for a living space). The thermal-couple would be placed between the discharge of the swampcooler, and the reservoir from the solar heated water. could enough current be produced to keep the water moving and fan blowing in a typical Florida summer day? Keep in mind you can create as much surface area as you want for the thermalcouples

[YbborNetsrek]

you shoudl reverse the heat and cold! Put this UNDER the campfire, built the campfire in the upper pan, cool the botto. That would be more efficient.

[caprine888]

hát sok értelme volt.



[rroge5]

what would happen if the pan was just painted black ? with nofocusing thing. i want to make a very cheap solar electric generator

[giant648]

does size matter on the cooler like the bigger they are the more volts they produce?

[GREENPOWERSCIENCE]

@giant648 Generally YES, they have more surface area and working material inside to produce more AMPS. Voltage is similar on all sizes depending on how they are made. Some larger ones do produce more voltage as well.

[heinrichguzmann]

@GREENPOWERSCIENCE

Any suggestion regarding suppliers?

I would like to have word about how they are made, in order to improve eff?

jesus.guzman@ge.com

[reesk92]

@GREENPOWERSCIENCE its amazing how must electronic componets work in reverse spin a motor an get voltage tap a piezo buzzer and get voltage or sound speakers work in reverse somewhat too its just interesting how that works out and all sadley pushing our cars backwards dont make petrol

[ajofscott]

@GREENPOWERSCIENCE in reference to the comment on the carnot efficiency of the petlier devices, the merit is in the lack of moving parts and the ability to utilize multiple heat sources whereas the good ol diesel must have fuel and is so darn heavy going up the trail....;)

[parrowman]

@GREENPOWERSCIENCE

you cant 'produce' amps. however you produce to ability to support amps. amperes is a draw and is determined by voltage and resistance. so question would be how many amps would a unit that size support?

[lexichronicle2]

If you wanted to get really smart on it, you could purposefully design the converter to make use of the high current potential you've got there. Magnetic field strength is related to the current through the inductor; not the voltage. By quickly pulsing the current, you very high field densities = tiny magnetics. Don't pulse too quick or you'll get switching losses. Google for national semi power supply designer.

[lexichronicle2]

8D Nice. The voltage from those is set by the junction band gap energies. The voltage you see is due to the resistance of the wires and semiconductors as the current passes through. You could waste a lot of power in that resistance, which will increase as you series them together. You'll be getting decent currents at those Delta Ts. Google DC/DC converter. You can buy them in tiny encapsulated packages and they'll bump your few volts to 5 / 12! Few solders and you're done. Easy-peasy!

[SwindleFlu]

Would it be possible to use one of your parabolic mirrors to heat it durring the day and save into a old drill battery then at the end of the day use the energy captured t o run a peltier for a short time to make a glass of ice tea? Also Dry Ice is plentiful and cheap in my area would be Possible to take a old cooler and put a bunch of those at the bottom and fill it with dry ice to produce electricity?

[KapteinFredrik]

Cool!!!

[jimbob3514]

Just made one of these and it worked very well... But that was no consolation to my mother who went bonzai when she saw her frying pans :( there was no warning on the website of the possible effects of drilling holes in your mothers frying pans...

[thebarathrumm]

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?

[electrique527]

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 :(

[fezants]

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.

[onskissjb]

it is pronounced -ier, it would take an acute accent on the e for the ending to sounds ee-ay

[drboose]

I can't wait to use this technique winter camping! Great video.

[cricketol]

what is the voltage and the amps that the heat pump is rated at

[cricketol]

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.

[definitionofis]

Data for 2 I found: thermoelectric-generator com 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 navitron org uk 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.

makezine com/15/seebeck/

had a commentary about watts/volts/amps for various TEC modules.

[chop98]

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.

[helpmonkey]

omg ... have you lost your mind?

[jrlakers84]

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!

[nearadyn]

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!!!

[hakanai]

you have to be careful because aluminum powder can explode if not handled correctly.

[biowerks]

Cool, I have a  few of those peltier units that I have been playing with.

[MrChawee1]

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?

[GREENPOWERSCIENCE]

Yes it would. The problem is more temperature difference, more current. It is easy to get +300f but difficult to get -300f.

Dan

[muddymuddymuddmann]

I Threw away a few of those 12 coolers with the silicon thermal units in them. It was a couple of years ago. Good to see you back in the swing again Though, Keep smiling and welcome back.

MUDDy

[Yellow2011]

3:42 "don't wanna burn up the wire...." looooooool

[luc59457]

The trick to not burn up the wires is to slightly and carefully bend the wire upwards.. In a permanent setup have the wires mounted on the heatsink, etc for the cold side... It is good to make sure the wires are siliconed at the beginning to help secure them. When the wire "touches" the hot side and is exposed to high temps, they will melt. I think for the tegs and maybe even the tecs, look into higher temp wire insulation.

[luc59457]

I am lucky, I have not melted any wires yet... But I had one where the wires pulled right out.. I could push it back in and it would make electricity again.. There was no silicone around the beginning of the wires for that one since I just pulled it out of a 12vdc refrigerator.

[weehydro]

I just ordered 10 x 136.8W Peltier plates from China. This could be great. Could this be better than hdyro power? People having their own small furnaces in their back yards burning their old newspapers and creating electricity? Hmm, this may not be good for the planet unless someone comes up with a cheap smoke filter for small fires (Do they exist?).

Hopefully I'll post a video demo myself in the future to show my results.

[weehydro]

Hi Dan, you said you've ordered a bunch of these. Can you say how much you bought them for? - I wonder if they could manufacture these as large roof tiles so that we could create electricity for our houses?

[speedsk8r010]

Horrible way to heatsink the heat.

Put an xigmatek dark knight CPU cooler on the hot side to keep it cool, you wont have any heat problems after that :]

[mrbuki77]

Show us more, and gives us price ranges on item costs. Thanx

[RamoneTalarico]

very fascinating,...converting heat to Electricity in such a simple way...

i would like to do this myself.

peltiers i read can last over 20 years of constant use..this kind of technology would be ultra reliable and durable for nearly any application...leacing htat out in the sun alone would get you energy...great video!!!

[sreenisheeba]

good

[cyphonyx]

I would suggest you try building a solar panel with these all over the back and then with heat dispensers all over that. This way you have a setup that takes the heat that makes the solar panels more efficient and turns it into additional electricity while cooling the system. To make it even more interesting, have these running fans that blow air over the heat dispensers for added heat removal. The temperature difference created will make both systems more efficient... in theory.

[luc59457]

Instead of using fans some will using bodies of running water. And it does not have to flow that fast, as long as it's flowing. You need quite an amout of heat to get these things producing anything significant from what I have noticed, you need a high td also, and your not going to get less than 0c on the cold side. And I used a frozen pot while the temp on the other side rose. so I doubt the back of solar panels will suffice for anything significant. My bets, 1v at most. from a module.

[sjh7132]

I like these demos, but if you would also measure the short circuit current, we could get some estimate of the amount of power there.

[ZED74]

2 part thermal epoxy would be better :) These are something i've always wanted to test out

[Odziz]

They used to use a similar system on French railways when they ran steam trains

[klaymen]

do you have numbers for all of these devices anywhere? i checked your site, but couldn't find anything. or do i just have to watch the videos to find out how many volts/amps your projects can push out?

[buddybill65]

Dan, I love the way you think! Keep up the good work!

[jtoptimistic]

possibly use an office watercooler/pet waterer (upside down bottle) kinda set up to keep a very thin, and easy to evaporate, layer of water to increase the cooling efficiency

[menderfire9]

Dan, you're talking my kind of camping.... 6 weeks out of the house playing in nature with cameras and laptop .... and cooking!

[Hamish121212]

Couldnt you just build the fire inside the pan?

[cappydawg]

Dan, thank you sooo much for putting this vid up.... ur great

[Mosfet510]

Cool video. If you were to focus light on the pan or something similar I guess you could get a decent amount of voltage/current with a series/parallel set up. Would be good for a solar setup to aid in charging deep cycle batteries in remote areas.

[ad3543]

Why didn't you measure the temperature of the water?

[brukins]

As I said before watching your vids I have found new or just uses for stuff I had purchased and thrown in a box somewhere.

Well maybe I will use that cast iron fry pan now.... LOL I mean the Peltier

[moravaman]

I love his videos to, but I also collect cast iron cookware and I would hate to see something that can last for a life long to be ruined for a fun 15 minute project. Please don't ruin your cast iron pans :-)

[brukins]

LOL I checked My Ex GF took all the Cast Iron Cookware. I still have the Peltiers.

[menderfire9]

moravaman, I'm with you on the love of cast iron cookware & because there is so much at yard sales I like to rescue it & give it new purpose because along with being a collector I put unbridled creativity way above collecting. A cast iron pan begs to be used in creative ways. You can just hear these two pans say "Thanks, Dan, we love being part of your incredible creative energy & usefulness; and we R so glad U didn't ruin the pans with the "pedigrees" so keep on exploring your inventiveness!"

[jazz61021]

Interesting! What are the rated watts for your device. I have found several on ebay from China used for computer coolers, 7 to 168 watts, but seems like your units are much smaller.

[tupac93013]

this kicks ass. i live in las vegas and its hot as hell im sure it will work really good

thanks for the great videos

[russell2nine21]

that's pretty neat for just slapping a couple pans together. It's not hard to see a nine or twelve volt recharger. and for the sound the uber profesionals do a voice over after the video so you can talk into a microphone as well as editing out the extra sounds.

[doug2877]

Another great production, nice video Dan. Do you suppose I could just slap a couple or more on my grill lid and run it into my charge controller, every little bit adds up over time.....LATER FROM THE WEST COAST

[KoolAiddroolaid]

Did you go to college for this?

I'd like to go to college to study this kind of stuff, but I don't know what to major in.

[IdahoViewing]

Are you talking about the peltier system or alternative energy in general? If you mean how volts and amps work the electronics would be your choice. You could probably learn the basics of Ohm's law (Volts = Current * Resistance) and the Power law ( Watts = Volts * Current ) from online sources.

[theCheskys]

I think all your videos are a great tool for the DIYers.

I just have a suggestion however. When your recording, your audio is kinda low. I am using my laptop and it's maxed out with the volume.

Not sure if others have the same issue with this video or not, but if they are I would suggestion using a mic. Thats if your cam has the option for an external mic.

[GREENPOWERSCIENCE]

Hi,

Thank you for the info, our good camera, Cannon XHA1 has the mic snap off so we are using a jack mic. I am trying to find a good xlr mic that is not $500:-) Thank you for the heads up.

Dan

[kingsdun]

That's cool.

Here's a thought.

Line water pipes and drains so that when I take a hot shower I could actually generate a bit of electricity from the wasted heat.

Or line a gas fireplace....

Or even an oven....

Why aren't products like those on the market?

[Sirmau]

Great vid Dan.... thanks

[luc59457]

Thank you so much Greenpower for making this video. It seems that as soon as you connect more than 1 in series their is an automatic internal resistance... I am thinking off a way to bypass this and simply have them power 3vdc batteries, in turn to all be connected in series to get your 12vdc etc... Only problem with this is you cannot run power from it while it is charging, unless their is a way around that.

[luc59457]

I have found some really nice 3.2vdc Lifep04 batteries at a high AH.

[GREENPOWERSCIENCE]

Hi,

[dtmbcorp]

You're on the cutting edge, Dan. Our future will be bright, if there are more people like you looking for new and better ways to do things.

[H2O2FromH20]

Was there any damage to the PELTIER units? They don't like to get overheated, must always ventilate or sink off the cooler side. A small flow of water would cool it at a more constant rate. Instead of fire use hot coals or of course the Sun , and use a thermometer for safety. Love your videos!

[DannysCam]

yay man good job

[UndeadGunz]

arctic silver 5 will improve thermal conductivity and they are about 5 dollars for 3.5grams

[SCENARIOBABY]

how about a stack of big metal sheets in stacks bolted together with lets say like 20 peltier modules connected on each level. say like total 100 peltier module unit with radiant tubing!

[vention4wh]

Imagine it! A camping frying pan with a USB port to charge your cell phone while you cook. Cool.

[taofledermaus]

I wonder if you buried the cold side partially in the ground for cooling while the fresnel lens heats up the other side would improve the temperature differential between the two sides?

[marthale7]

I have watched other videos and some take some of the electricity of the pelter and cycle the water with a small pump thus increasing the efficency of the cooling . Might try a small aqarium pump and see if you can get more voltage with say a 5 gallon bucket of water. Cool video Dan, I also am now in Florida in Ocala, many clouds overhead. Cheers

[GREENPOWERSCIENCE]

Thank you for the great comment, stay dry:-)

[insAneTunA]

Nice video Dan, I can imagine that there are a lot more ways to use this.

You are very welcome, I already thought that it would be an inspiring video for you. I enjoy watching your videos a lot as well, so I want to thank you for that. I hope that you and Denise are able to make more videos in the future. I have watched the video that you suggested and it's indeed very similar to the design that PulseFuelNerd is making.
