You can buy a "Biolite" camp stove which will charge cell phones , etc.

beat me to it LOL

The one i have (and it´s quite big and has maximum input power about 16volts and over 3 amps i think) is not able to to produce more than like 1,5 volts, even when was cooling it directly with running water. Then I ripped off a circuit from solar garden light,because it works like joule thief -and i was able to light up LEDs really good, but i would say Stirlings are better. Sure, this is awesome thing and you can charge batteries with it, but it is not to too much compatible, the voltage is low (amps are very good) and it is pretty expensive. Also you need the same voltage all the time to charge something safely. Without joule thief it is not so great except it can cool down things. the vid:)

Thank you for an interesting video, though not quite an instructable. Gave me new bright ideas. Have a good day!

Does the heat need to be on the bottom? I'm thinking use a black one on top (painted?), and immerse the bottom one in a container of liquid fertilizer/nitrogen, then expose the top to the sun. It'd take a few minutes to gear up, but should run fine with continued sun.

oldmanbeefjerky (author)dmarsh552012-04-22

you do understand that high nitrogen fertilizer doesnt contain liquid nitrogen right?

The best way to use this outside to create free electricity, is to pair it with a solar cell. attach the hot side to your panel which gets quite hot naturally. attach the cold side, to a simple water evapourator, which might consist of a heatsink / aluminium sheet, with a cloth/sponge which will draw water which will evapourate keeping the cool side below air temp. or at least prevent it from balancing out as easily with the hot side.

Keep in mind copper is a good conductor of electricity, and copper sheet can be used to transfer heat . aluminium however is good at dumping its heat.

Not to rain on anyone's parade but Peltier modules are a VERY inefficient way to convert heat energy into electricity. They are very expensive and do not provide enough useable current to be of much use unless you just want to power up a few led's or a small fan. I thought about just attaching one to my wood stove but if you have to buy you are not going to get much bang for the buck. Interesing instruct able tho keep up the good work...,and if it were me I'd scrounge one out of an old electric refrigerator/ cooler like the Coleman line.

The light you get from the candles themselves is way more than you'll ever get from that lightbulb.

witmoreluke (author)2011-05-30

How about instead of candles, you try a Fresnel lens? I've seen those things make pennies explode like firecrackers. Get a small one, check on for old overhead projectors and such. For larger ones, check out:

He tells you how to get them. Even if you don't plan on building one, it's a good read.

dmarsh55 (author)witmoreluke2011-07-17

you can also check out American Science & Surplus - LOADS of neat stuff, cheap. Ex - page size fresnel lens, $2.98

jules15 (author)2010-05-12

What does thermal grease do??

randomray (author)jules152011-07-17

It provides better contact between the separate pieces and therefore better heat transfer .

bigt4616 (author)2010-07-14

so, in theory, this could be used in electronics to recover electricity in say a cpu chip? and if it was good enough recover all, well, never all but most of the electricity lost in computers? could you have a computer that runs on like 1 watt?

boygenuis32 (author)bigt46162010-07-22

No, Peltier cells use heat on one side and coolness on the other to generate energy. They are often used in computers, but in the direct opposite capacity, as when electricity is put through the cell, it moves heat from one side to the other, which is great for cooling hot components.

randomray (author)boygenuis322011-07-17

Thanks for that information .

killer pyro (author)2011-06-29

well you have to spend some to get some but in this case save a little or some

Damp Cuttlefish (author)2011-04-20

peltier cells arent exactly free energy, they operate at lower efficiency than conventional solar panels most of the time

oanderson (author)2011-04-06

Do you realise that it's not free when you have to pay for candles / blow torch and other stuff

FRED MAXEY (author)2011-03-29

I see you are on the right track, The problem being obtaining free heat & cooling at the same time, It is only because you, as most others were condition to think in strait lines, Learned from books or others that were lerned the same way.Take some time to sit in the woods alone for a day or two with nothing but your thoughts and you will find the soloution, But I will give you a hint to get you started, Swimming pools. summer sun. All you have to do is get away from tecnolagy for a short while for the lite to go on. Dont give up , your almost there.

jherbolario (author)2011-03-28

Why not just use the candles in lighting a room instead of using peltier modules?

vincent7520 (author)2011-03-27

But one thing I don't get : why do you claim this electricity is free ?…
As with the Stirling engine you need a candle to heat it …
If you ue solar power ok this is free, or if you can use wasted heat from all appliances at home and the office, would be interesting …
Otherwise, it is just a Pelletier effect no ? …

-max- (author)2011-03-06

this gives me an idea if you were to use the panel in between a heat-sink and a bunch of transistors/regulators in a circuit then the output of a panel connected to a joule thief circuit which will be wired back into the input of whatever the circuit is with all the transistors/resistors can you increase the efficiency of it?

NeuroPulse (author)2010-08-01

"No sh**t !!!" What is the point of replacing characters if it is obvious what word you are using? There is none. It is still profane. You are still communicating the same thing. Please refrain from using profanity.

Cobalt59 (author)NeuroPulse2011-03-04

Mmmmmm.... I believe that you just communicated profanity.

sethzor (author)NeuroPulse2010-08-01

no shoot .... yea really profane. Please count the characters before considering profanity.

Saturn V (author)sethzor2010-08-24

You couldn't count all the grammatical errors on this site. For all he knew, that could have been one.

NeuroPulse (author)sethzor2010-08-01

LOL. It is hard to believe you do not realize that "no shoot" makes no sense and that you think he censored "shoot".

sethzor (author)NeuroPulse2010-08-02

I know what he means however the difference between you and I is I can count as well as remember when people said "no shoot"

Cobalt59 (author)2011-03-04

Heating the water costs money. Fuel costs money. Running a PC costs money. And you can't power the PC with the Peltiers module because of the laws of thermodynamics. Not really free.

SaraHawk (author)2011-02-27

Not free if you have to buy candles and/or butane gas to heat, is it?

ALEX_HOLAND (author)SaraHawk2011-03-02

Solar Heat?

Car engine waste heat?

all other sources of heat, even your pc produce heat

Foxtrot70 (author)2011-02-04

BMW was doing some experiments with these in an effort to replace the vehicle alternator. They were using a pile constructed around the exhaust pipe near the manifolds and then for the cold side a seperate radiator with cooling fluid. I don't know if they had enough success to offer it on their cars but it sure looks interesting. Another application might be to use this setup to produce electricity for HHO production. One of the problems as I understand it is to not us power from the engine to produce the HHO thus not increasing the fuel consumption. There is a video on You Tube showing the BMW setup.

Tangoforce (author)2011-01-27

Nice idea but somehow I think the cost of candles would outweigh the cost of normal electricity. Candles aren't going to burn more than 12 hours and if you need 6 of them to generate 7V then.. well you see where I'm going with this.

Thanks for the entertaining video though ;)

likewho (author)2010-09-22

I’ve tried standard peltier modules for power generation with limited success and very short service life. They cannot hold up to the higher temperatures necessary for good power generation performance. I found a terrific supplier with both standard temperature and high temperature TEG modules designed specifically for power generation. They sell a lot of devices on eBay and you can also buy from them direct. The company is Thermal Enterprises and here is are links to a couple of their eBay items.

It isnt chep energy

seandiggidy (author)2010-09-03

Sterling engines can reach efficiencies of over 80%. These couplings max out at about 10%. They are much simpler, however, and very dependable...

omgitzstegman (author)2010-07-23

Nice video, I can see you put some time into it. 

The amount of energy wasted from those candles and the torch are insane.  You're only getting a fraction of the energy from the candles to the lightbulb.  Then there's the random torch...

To put it very simply, a single candle is many times brighter than the bulb. 

I guess my point is, if you want to light that bulb, just light the candle instead :)

Remember, there's NO free lunch in physics.

Moomba champ (author)2010-07-13

sorry but these are not as efficient as a sterling these are about 5% while sterlings can be up to 40%

amando96 (author)2009-03-13

what if you put ice on top of the radiator?

mieszalniapasz (author)amando962009-03-14

So you'll get more performance, but to big difference between surfaces may crush semiconductors.

amando96 (author)mieszalniapasz2009-03-14

ya the thermal diference... btw what is that module thing?

mieszalniapasz (author)amando962009-03-14

It will increase voltage and amperage

Joenavy85 (author)mieszalniapasz2010-05-12

not sure how you raise both, the wattage output is constant, watts=volts x amps. if one goes up the other goes down, that's why high tension power lines are such a high voltage, that way the wattage can remain high but keep the amperage low (to minimize heat losses)

darkevilapie (author)2010-02-12

you should do it this way:  put the hot thing under the chip cuz heat rises and the cooler on top so u can mount a fan on it. just saying:P

lukeyj15 (author)2009-10-31

 if you made the hot side the same, but put ice cubes on the cool side, you would get heaps more power.

jehvillazor (author)2009-09-25

hi,please i'm just thinking where can i get these radiators that you use?????tnxwant to know,

doodadica (author)2009-04-16

These things are great. I just wish it was easier to get more voltage out of one. I fried one using a Fresnel lens on it. The radiators I used were very small though. I'll have to pick up more of these things and experiment. Anyone know what type is best as a generator, or does it matter? Also anyone know a cheap source of them? Thanks!

Rustywhiskey (author)doodadica2009-09-23 has them on sale now. They seem to be a reliable business as I have bought from them before. Did you focus the light from the Fresnel lens directly on the Peltier or did you focus it on a heat sink attached to the peltier when you fried it?

mieszalniapasz (author)2008-09-18

Yes, that thing costs $20. How much costs wind generator or solar panels? Thousands of doll's?

EcoMotive (author)mieszalniapasz2008-09-19

It might have only cost 20 bucks but if you laid that out in the sun you'd be lucky to get half a watt. So this thing costs about $40 bucks per watt. Just a random example of a solar panel I came across was 190 watts and cost $800. That's a tiny bit over $4 per watt. You could also buy solar cells and DIY your own panel and cut the price by half. Not to mention, if you had an array of peltiers you'd have to set up an intricate large scale system for dispersing heat from the cool side of the unit. You can mount a solar panel almost anywhere the sun shines and forget about it.
