Thermoelectric power generator

[deluxeassortment]

@cxaxnxexs looks like an old Scythe design. Scythe Ninja to be exact.

[cxaxnxexs]

also, i am very curious, who manufactured your heat sink?

[cxaxnxexs]

very space efficient design. I am in the process of developing something similar. I am having trouble navigating the website since it is in Japanese & google translator is not very good... It would be a huge help to me, could you please provide some specs on your design (power output, temperature difference, TEG model, etc.)? An interesting experiment would be to see if a fan would "pay for itself" (in terms of power & overall power density) by using it to cool the TEGs.

[TheIvomendonca]

Is possible but the peltier will not last long.

[Thudothwacker]

What if you use two peltier. Connecting two hot side with a heat sink in between. Powered by a series of rechargeable battery with switching mode. You use batteries one at a time for your lights and the petlier to charge other batteries. You have infinite source of energy

[brandenwolmarans]

one could use the electicity created by tec and sunpanel to charge ups >that powers house lights with 12v led`s

[benjorgensen1]

i just thought of something, one of these attached to a sterling engines cooling cylinder. that would serve two purposes, to make the engine run faster and generate electricity that could even run an electric motor that helps the sterling engine run a bit faster.

[heartlessvietboy]

What is the Fuel Source of this Generator?

[willavr]

@heartlessvietboy Termoelectric silicon junctions that produce current when one side of the peltier is heated and the other side cooled. Ice and warm hands works.

@heartlessvietboy I did not just type @, that is what youtube auto puts in when you hit the reply button, which is what I did. It does look like people see it.

[peterroumian]

@heartlessvietboy

heat

[TheRealDealinlife]

That is cool. How does it go?

[SoulofaDeity]

They should use these in cars. The motors would turn on the second your ass touches the seat. Think about it people, allow a simple breeze to flow across the motor for the cold, and your plump tushie for the warm. For emergencies, use dry ice.

[spinners9462]

@SoulofaDeity That would be a legit idea, but a plump tushie and a cool breeze would barely be the temperature difference needed to power anything useful :(

[redodrago]

god damnit y cant scientist use drug (steroids weed etc.) to power our eletricity!

[mmaaxx1198]

@redodrago Henry Ford's first model T's ran on hemp (weed) seed oil. So we scientists already did that for you, you're welcome. All jokes aside, what you are missing is the purposeful disuse of the hemp oil for fuel, thats the key, its not that things aren't possible, its that rich important people don't want you to do everything that is possible, it interferes with them cheating to make money because they don't have the abilities to make things possible themselves. They drag us down!!!

[ff29sask]

Don't trust TEG power dot com. If you order from them, they take your money and don't ship what you ordered. I ordered over 1 year ago and still haven't received the woodstover generator I paid for.

[roofy2k]

interesting, does the little bit of air moved by the prop help cool the heat sink?

[ChineseLearn]

Can you make a cooker if you reverse the use?

[super3slug]

@ChineseLearn if you apply a voltage/current you can make one side hot and one side cold yes

[ff29sask]

Beware of Tegpower dot com - they have ripped me off. I ordered and paid for a woodstove generator like their video but they just took the money. Repeatedly lied about when they going to ship and never die..

[spartaeus]

Doesn't that just use a thermocoupler to generate electric to run the fan?

[Avataryoutuification]

lol isn't that a lga 777 socket heatsink? Actually it looks bigger..

[jsusche22]

We have a remote control car that runs off a thermoelectric unit in my lab. Simply connect the thermoelectric to the car, place a hot chunk of metal on one side and place dry ice underneath the other side. Works good. Would work better if the damn thing would steer properly...

[ashensunhappyonion]

idea

a magnet that pulled something or a rotating thing and keep going

magnet force+device=ultimated energy or something of the such

but not using any energy but what is created

[mindhasyou]

Now if eveyone bought and, modified this product, we could start a market based on inovation. Alas, inovation is only for those who dare to inovate!!

[1foxtrot70]

BMW was doing some tests with the Junctions to create a DC generator using the waste heat of the exhaust and eliminate the alternator and hopefully increase MPGs.

[12dart12]

nice. i just ordered 4 of these of ebay for under £10 :D. cant wait to get them. might try make a mini ac unit with my left over heat sinks and fans :D

[Ebdan88]

Think of making a roof of a house with some inviremental friendly material which is able to generate Electricity too :-o..... Who says Fri Energi doesnt Exist!!!?

People have to really start waking each other up to this fact........

[LostInMadness220]

@Ebdan88 The roof collects so much heat. From the sun and from inside. All meets in between.

[mindhasyou]

@Ebdan88 Their are two kinds of people my friend. Those who are awake, and those whome will never wake up. Quit worrying about other people, it's a personal sign of weakness. Charity is sweet, but when the honey is all the sweeter, we feel mick quicker.

[Ebdan88]

@mindhasyou Dont you get Tired when you go out and speak to people and there are people who dont know what Chimtrails are, even thou the planes all the time are flying and spraying...THE Sheeps dont even look up during the 7 days of the week, HELL some of them they dont look up even once a mounth !!?

What if there was another world where we could send all the EVIL, and Sheeps there, and live for ever happy....?

[prankmypants]

what rating motor is that?

[boxa888]

iron and copper is all you need right? i have an old electrical book that talks of heat sink technology, the iron and copper connected at a point causes the heat to move the electrons in the wire in a dc current.

[seneca65r]

Clever, Thanks for posting. Food for thought!

[giant648]

can you put something cold on it and will it make power then?

[mikeccuk2006]

@giant648

hot or cold works both ways

[giant648]

@mikeccuk2006 thank you very much i can see me sticking this in the snow making power awesome!!

[RamoneTalarico]

what motor is that? i would liek to get a few of those to start projects

[Pianoman0488]

I really enjoy these little contraptions. I saw one once that got its heat from a wood stove and warmed the room in this manner. I also think there is a lot more that can be done in the realm of thermodynamics and thermodynamic systems like this. Neat video!

[combatplayer]

what if u put the heatsink inside of a white isolated plastic or metal bowl facing down and make a hole in the top where only the surface of the thermoelectric thing gets through so that you can mount a black piece of metal on it, put it outside and that way make some alternative solar energy?

[macrumpton]

@BiDaDiKuNuKu Actually no. Stirling engines use the changing volume of a gas when you heat and cool it, and devices like this use the flow of electrons between dissimilar metals when heated or cooled.

[rboos]

What if the fan flow was ducted to the heat dissipator only, the temp diferential would be higher... nice work!

[rboos]

Thank you for sharing this!

[CheSuerte]

crap I wish i could know japanese...

nice video dude

[spartonne]

Sweet. So the cooler object causes the motor to rotate counter-clockwise and the warmer objects (riceball and hand) causes clockwise rotation (reversed polarity). Sweet as. This stuff is used on deepspace probes I think. They put all this around a plutonium reactor or somthing. They should put these all over the exhaust system of hybrid vehicles to help charge up the batteries.

[FireBirdsGo]

Fascinating! Someone should scale this up.

[PirateofFordLake]

Some powerful people wouldn't like it

[macrumpton]

@FireBirdsGo The problem is the amount of energy available is proportional to the size of the generator and the amount of temperature difference between the hot and cold ends.

To power a laptop computer you would need a unit the size of a mattress and far more temp difference than your hand and the ambient air temp. It would be very expensive.

[donkeyface69]

wheres the fucking audio

[DigiTan000]

Do we really need audio to tell what's happening here? :P

[luc59457]

Come see my channel, a TEG has much more Potential than a TEC... I have some videos to show the difference

[Biogem369]

Thermoelectric Cooler

[loon8801]

how much voltage of Peltier module your are using?

[Anothercoilgun]

In the beginning it looks like a gravity drive. Place some weight on the peltier and the motor is powered FOREVER!

[Piscivorus]

Try connecting the power directly to the motor instead of the cpu. You should have better results. lol

[xdaemoon]

How work this system? How genrate electricity from the temperature?

[ryansleis]

Sir it looks really interesting!!! What type of thermoelectric did you use? how much wattage? Can I get easily from ebay?

[kal9001]

thermocouples as been known about for quite some time, The old Voyager space probes use Radio-isotope Thermo-electric generators (RTG's), they have a heat sink outside and a super critical radioactive element inside and they have powerd the space craft for decades. The problem is that thermocouples are usually very inefficient, Although I do think wider use of them to recover energy from otherwise totaly wasted head would be very useful.

[irisauser]

That's awesome, I've never even seen a generator that works like that until now.

Thanks for the video.

[terry735001]

well i am not good with things like this but frist thing i think when i seen this is wheres the fan at thats making it move blow air over it wouold make the motter move

[VolkgartenBySquirrel]

I think a sterling peltier device could provide usable current, even if it just supported a local lighting circuit. On a large scale, I envision two units, together with a chemical circuit for a heat sink, to support a microutility.

[crazyhugs]

what heat sink is that?

[dtadpole]

Looks like a Scythe NINJA.

[NamelessFTW]

requires a temperature differential... would be nice if someone could figure out how to just turn plain heat into electricity.

[funnoworlando]

thermionic converters and thermophotovoltaics convert heat directly into electricity.

A temperature differential is always going to be needed for a couple reasons.

First, if you are converting some heat into electricity then the side gaining the electricity will have lost heat,  It has to be asymetric, or there won't be any useful voltage.

second, the temperatures at which thermionics and thermal emission occur are very high, and temperature has to be reduced for materials and you and i.

[TheAmericanPageant]

That's the whole concept of a thermoelectric power generator, to generate electricity directly from a temperature difference. Just like a photovoltaic cell that creates electricity directly from sunlight, a thermoelectric power generator creates electricity from plain heat.

[Alexvideoclip]

efficiency is only %10 - %10  :o(

[luc59457]

No, Efficiency is not quite 10%... But if you look into it's potential, it could make great competition with solar panels.

[payaning2x]

wow it's free energy hahahaha

[librapig]

nice work, Im very interested, could you display the design, or maybe send to my e-mail?

[goldy1011]

explain pleasewhat this all about....wht are the component...the pictorial assemlby diagram..

[Mastahscott]

where can I get one like it to play with ? How much was it and what part number.

thanks

Scott

[tjgame2]

check ebay for peltier the pic shows a peltier in hand

[globalgaucho]

you can use this with body heat or de diference between black and white object under the sun ligth

[mutwa]

Nice video demonstration..Thanks for sharing. Off to buy some peltier modules!

[etepoloccip]

I'm guessing this is not a basic Peltier Junction because there appears to be too many wires.

[zeophoto]

Oh yeah, I think so. Theres only two wires spliced into each other, the rest are those copper heat-pipes used also by some stirling engine designs (as Peltier junctions are motionless stirling engines). Efficiency is the product of the heat differenctial and heat-loss.

[etepoloccip]

Okay, I guess I can see that. I've never thought of a peltier junction as a stirling engine - but I suppose you are correct with that comment.

[nelbmahs1]

I think there are two stacked together

[qwertypenis]

A peltier module is not a stirling engine. They are both heat engines but a stirling engine must use a gas as working fluid.

[tjgame2]

Wouldn't using the sun and the earths cool ground or a stream ,make a current. I just ordered two peltier's for $10, Ill be playing with them soon.

[mutwa]

Yes, I had this idea a while back. If I had the money, I would get hundreds of these mounted to copper in the ground, and a black mat surface above ground. Only limitation of power is how much money you have.

[trailkeeper]

@tjgame2 You can try focusing a "page/sheet" magnifyer fresnel lens on the surface to be heated. I've seen them for sale at "thrift shops" for a dollar. Right, a stream of cool water on the other side would make a huge temperature differance. Should be enough to recharge some batteries of something.

[gtq838]

@tjgame2 yes that works... I think the main problem is temperature difference. for example if you have a 20 watt peltier one side will get flaming hot and the other freezing cold the reverse would be true to generate 20 watts you would have to get it freezing cold and super hot on the other side.

[gaptoofgranny]

@tjgame2

Yes it would actually. If you plumbed a water circuit from the earth to the TEC's and pumped the water using some of the generated power, you could potentially create enough difference that you could power a trailer.

[HostileHST]

@tjgame2 Did you experiment? I like your stream idea and you could use magnifiers or bend mirrors to focus high amount of energy to the peltier.

[bearpatch626]

@tjgame2 were do i get a couple of these?

[willavr]

@bearpatch626 eBay

[blackXSpr]

I just designed (roughly) a stirling engine that uses water piping and a peltier module.

The problem with stirling engines is keeping the temperature difference existent, as normally heat would conduct to the cold part the same object. What I did is created a piping, channeling hot water to the hot cylinder and cold water to the cold cylinder, they meet seperate from the stirling engine at a peltier module, which powers the water pump.

Is this not a relatively self-sufficent design?

[qwertypenis]

Well you neglected to mention your energy source which is really most important part. If possible it would be better to apply your heat source directly to the Stirling engine. Using water as a transfer medium will only introduce extra inefficiencies.

[blackXSpr]

But other heat sources require constant heating. I am not talking about a lone stirling engine, but perhaps a series of them, in which case the peltier modules from each could drive a water pump for all of them and the problem with stirling engines now is the heat transfer to the engine cant be constant, but with water it could be. The water would be drawn from a huge container, which could be so much as flame or solar heated, nothing too complicated.

[qwertypenis]

If your talking using the water as an energy storage system like for use on a solar system at night. This would work to a limited extent but you won't be able to make much power because your temperature differential will have to be less than 100 degrees. This is what's known as 'low grade heat' and billions of kilowatts of it go to waste every year because its not deemed economical to extract the energy.

[blackXSpr]

Thats not what im talking about at all, thanks for your time though

[LostInMadness220]

@qwertypenis Is this part used on the pistonless solar dish generators?

[Onach17]

What type of TEG did you use? Wismut telluride? Can you tell me the name of the manufacturer?

Thanks!

[KiyotakaT]

Incredible!!

[monsterfrogz]

can you explain to me why this happens? what causes the electric energy?

[KiyotakaT]

I have seen the professor who made it at SFC.

[sspoke]

[etepoloccip]

A Peltier Junction is a semiconductor (PN) - on the order of a diode. That type of device can act as a heat pump or generator. A difference in potential (temperature or voltage) causes a transfer of energy. Very interesting stuff...
