Generate electricity from your body heat

[chandradarsan]

nice video ......

if it is possible to charge cellphones with our body heat..

[TOOLER98]

Can it work on torchlight also?

[jayejayeee]

very interesting video thanks

[tridentvii]

how to make it?????

[simysimss]

interesting video and very informative

[acnfanmanin]

That would be great for computers so if the computer gets hot it can make power for a fan using that device.

[permofit]

wow 36 amps is that right ?

[jamtracks]

now put the fire on top of your hand..

[olymyoted]

it was having and orgasm

[danich45]

WE RECENTLY HAD A POWER OUTAGE THAT LASTED A FEW DAYS, I LITE CANDLES FOR LIGHT, WOULD HAVE LOVED TO BUY SOMETHING THAT TOOK THE CANDLE HEAT AND MADE IT INTO USEFUL ELECTRICITY, TO POWER A 12 VOLT ELECTRIC BLANKET OR SMALL ELECTRIC HEATER. EVEN A STRING OF WHITE LED LIGHTS WOULD HAVE BEEN BETTER-I LIVE IN AN APARTMENT BLOCK AND CAN'T USE A PORTABLE GENERATOR ANY IDEAS

[fairyheli2]

@danich45 can't power an electric blanket with a candle, or a heater, maybe you could power those with a gas cooker, but you are better off just using a gas heater, candle fumes are quite toxic

[d4m4s74]

They should put that in every cellphone so it get a little more energy while in your pocket.

[karpaaz]

hey, you mind telling me what that liquid is (placed below the rod where the peltier element is placed) , it would be grateful of you to tell me, as i am planning to use the same model for my school's science fair

[MucusFelidae]

The motor is getting drunk at the end.

[carloloy123]

thanks good thing you labled the hand or i would not find it when i do the experiment

[adracamas]

LoL, learn to grammer?

[videoclipits]

What's that thing attached to the hand.. I didn't see a post-it

[mhytbuster52]

i cant see. is that Amper or MiliAmper?

[dufusrunescape]

put that with your campfire for laptop power

[AZIlluminati08]

@dufusrunescape learn to grammer,



[Mikeyc826]

Nice !! Nice !! Does it also work when the sun hits it ?

[RamoneTalarico]

if only they could make CLOTHES convert body heat into energy.....

[ricktbdgc]

Can you generate enough charge from the human body to at least keep your PDA charged fully? How much would this cost to make a body charger

[electrodacus]

@ricktbdgc It will probably not be healthy since you cool the body.

The human body loses heat equivalent with about 100W to 200W so let say you cover 1% of your body with thermoelectric elements that is 1W to 2W of heat energy and from that you can recover about 5% using the seebeck effect so that is at most 100mW and depending on PDA it may be enough but I will not want to get painful bones and cartilage because of this.

[LittleJohnEnterprise]

Porn music :)

[Krb68691]

It's aliive! It's aliiiiiiiiiiivvvveee!!! :D

[myNerdStuff]

i made 5,6 watts from heat withe a simple DIY watercooler system

[GT5Enthusiast]

glad you signified that was your hand. almost thought it was your foot.

[a2zhandi]

@GT5Enthusiast you shouldn't even be allowed on yt let alone make comments as ignorant as this!

You missed the point because of your ignorance

[julius16465964]

the toy going crazy :))

[LaLaLaLaScouter]

Hey, are you gonn a make a video on how you made that? Its GENIOUS!

[LaLaLaLaScouter]

A+ on project. Thank you SOOOO much!

[hr1100]

We should make chairs with these peltier elements. Our asses will provide all power humanity will ever need just by sitting and browsing the internet.

[cooblades]

Its called a peltier element. you can buy them on ebay.

[YOanimator]

where can i get one of these or make one????? please answer

[parek142536]

@YOanimator the element name is peltier modul and you can get this on ebay or i any electronic trade :)

[policekiller305]

thats that geothermal huh, u kno one day were all gonna say fuk this gov devil worshiping iLLuminati n mod r own shit to avoid payin for things that need gas,,,safer,cheaper more efficiant, im already starting to mod my own shits,,,, im thinkin of stealing all those solor pannels on the highway, put them on my roof or some shitt lolz

[TheCameoAfro1]

@policekiller305 YEAH!!!! REVOLUTION!!!!

[drumsrule786]

What I really want to see is a giant version of this in a fireplace, one outside and one inside facing the fire. Light up a log or two and bam electricity for the house

[drumsrule786]

@srdickens That wouldn't work. There is always diminishing returns, as in you would get less power in than you would out. If what you said was possible I'm sure it would be in every house in the world!!

[curly95432]

@drumsrule786 Actually, technically there are never diminishing returns - there can't possibly be due to the principle of conservation of energy.You're probably referring to inefficiency in converting energy from one form to another, but it's always converted to something.

srdickens' idea is useless for a different reason though - insulation. All heat would be lost without proper insulation. And if you had enough insulation, the system would be redundant as you'd never lose any heat anyway.

[drumsrule786]

@curly95432 the diminishing returns are the inefficiencies. I wasn't saying that there was energy loss as a whole, just from the system itself. Also even with all the insulation in the world it will never be fully self sufficient. Like I said, there are always diminishing returns. In addition to the heat loss, the wiring itself has resistance, copper, while very conductive, is not perfect, it still provides resistance to the electricity. As you can see there are many variables at play :)

[intheshitter]

Thanks for the notes, I thought it was your dick or something

[ideeman1994]

whats the difference between a seebeck and a Peltier unit?

[Kariudosan]

@ideeman1994 It's essentially different names for the same thing.

Seebeck is generally associated with temperature difference + 2 different metals = electric power

Peltier is generally associated with electric power + 2 different metals = temperature difference

There's a bit more to it, but that's the gist of it.

[todkapuz]

add a small radionuclide source to it.. and send it off to the stars... how most of our deep-space probes work.

[Trelos1Epistimonas2]

Bravo...i liked it

[IgorHW]

How much power could you get from CPU heat from inside the computer? It would be good for automatic fan speed control.

[Sniper45mm]

what kind of conductors are those?

[ccraig412]

Wow... How Efficient! 5  volts at 735 Degrees... -_-

[HostileHST]

@ccraig412 I thought the same thing, but a person could, trying using mirror(s) focused onto the peltier, now you have the sun to really crank up the power.

[p00pindas00p]

@ccraig412 They're typically less than 10% efficient. This guy is a moron because he has a heatsink on top. What matters isn't the heat, but the temperature difference between the sides. He'd be better off putting the heatsink on the cool side with some thermal grease for that reason.

[BLUEPUNK86]

@ccraig412

think about your car temp recharging your battery.......

[ccraig412]

@BLUEPUNK86 True. But A car gets around 195-215. Which means it would need another water jacket, aswell as some other stuff. Its easier to have a Alternator throwing out 12VDC @ 60Amps or so once going 700RPM or so. :p I was thinking about using this to charge a cell phone but it would require (my phone atleast) 1 amp @ 5VDC. Which would take quite a few of these and a good cooling system. :-/ A Stirling engine with a little motor on it would be more efficient. lol

[minimichelson]

@ccraig412 Well they are connectable in Series & Parallel & considering that engine exhaust leaves the engine at aprox 1200F and is simply wasted thus 5+v is better than 0v

[ccraig412]

@minimichelson Yeah true, but the vehicle already has an alternator that generates about 60 amps for the vehicle. This would be no help. However, it would be good if you could mount them on your roof on heat panels of some sort.. Otherwise, your alternator doesn't really have an impact on fuel economy. But I get what you mean though.

[taluntain87]

put it on your toilet seat you sit down and the lights turn on screw the clapper we got the sh** and see lol but seriously that cool

[ToddWalther]

This is cool. But unfortunately, this unit will recover only 15% of the energy deployed by the flame. Which mean, there are better way to do energy from thermal energy.

[MrGoogfan]

more like 3%

[xteaopia]

ummno, its much closer to 15%

[definitionofis]

@ToddWalther Can you name one ? The small Stirling engines are 1.1% efficient as per the youtube experiments I watched..

[spaceshipearth999]

i've been thinkin about gettin electricity from concentrated solar , i dont like most approaches there too complicated/wasteful. i need more direct system like this . until photovoltaic is cheaper.

[fronkenpoop]

Interesting.

[odi22865]

totaly love the post-it's :D

[callthecuzins]

bahhahhhahhahah lol

[field16]

Of of today's date, a single one of these "Power Generation Modules" cost $75! (Part # G1-1.4-219-1.14) Way more expensive than a solar panel for the same 5W output and with this unit you have to supply fuel (or energy) to produce the heat and ice. Looks great as a video but not as practical as using a 5W solar panel.

[Paulisfalseprophet]

lol $75??? where are you going to buy?? thats outrageous! I have many of these TEC's and TEG's. i bought about 25 for $500. go on ebay and search for "Gigantic 62mm - 545 Watt Thermoelectric Peltier Cooler" and prepare to SHIT YOUR PANTS!

[field16]

Agreed...the price of the module used in the video is outrageous. I forgot how I found his part number... maybe from his guide at instructables.

I bought some Peltier coolers for far less, just $12 each (and made a video with it in use).

[chop98]

25 for $500? Man, I just got a 168 watter in today that cost me $7.50. They offered me the 545 watt for $23. And the price would go down the more I bought.

[Paulisfalseprophet]

yea the dang prices are comin down... so i paid $20 each ;)

i'll be experimenting with extremely high voltage and very little amps on a few models. the secret is actually pulsing the electricity to keep the heat losses to a minimum. people say the efficiency of these things are only 10% or so, but with pulsing high voltage, i think i can get it to 80% or more... . my TEC's are 25amps max but how can you get this at 15 volts max? its ridiculous... time to sacrifice one of my TEC's lol

[Paulisfalseprophet]

ah crap looks like i've been beat... google analogtechnologies for some impressive 98% efficient TEC modules!!! i just pooped myself!

[Paulisfalseprophet]

oh wait i have a bit more to read... apparently their CONTROLLERS are 98% efficient... maybe the TEC's are more efficient too? hmmm... more reading i go!

[chop98]

hehe. good luck, man. :) don't make any frankensteins.

[Paulisfalseprophet]

hmmm good idea... jk

the pulsing will help keep the heat losses down to a minimum :) just like stan meyer's hydrogen generator

[PyroEvil]

Somebody did test to compare a "Gigantic 62mm - 545 Watt Thermoelectric Peltier Cooler" and a normal 40mm 91watts for electricity generation? The 62mm cost four times more than the 40mm. It's produce 4times more power for electricity generation at the same temperature difference? I'm not sure of that. You can got on ebay 100 40mm (136W) for 455$.

[myNerdStuff]

@PyroEvil i am using the gigantic 62 mm, and max. power from two off them has been 5,6 watts/4,35 Volt/1,3 amps

[ohnedich42]

@myNerdStuff I have 5 of these, plan on using 12, I found a heat source that stays around 120F, for about 8watts. I plan on hooking it up in my garage for winter, gets around -15 C here , I think that they should put out a minnimum of 50 watts, thats just my guess, hope its more, as long as the output is more than 8w I'll be happy

[Afrotechmods]

What is that flat, brown, textured substance underneath the multimeters? I think it needs a label for clarity.

[thedrnailsguy]

LOL. I was thinking the same thing. And what about that device he was using to add the heat?

[crob227]

looks like icewater seems like i seen steem when he lit it.

[desertblbuesman]

is that 19.2 milliamps on the meter? At first I thought I was looking at 19 amps and getting all exited, but remembered these meters usually have a ten amp limit. what is the cost of one of these and do they come in varying sizes? I have a solar concentrator that gives free heat. if these are cheap enough....??????
