Author Topic: 25mV Joule Thief powered by peltier merely using our body heat -Free energy 24/7  (Read 175226 times)

Hi everyone,

I have finally created a Ultra lowest simple Joule Thief circuit which self oscillate\start with mere 25mV in my quest for free energy.

Our body radiate heat 24/7 even if we are sleeping.By using peltier we could tap into this heat constantly being generated by our body and the cold side is just the surrounding temperature with small heatsink.
Since i am living in a hot country the temperature difference between my body and room is only 6.5 degrees celsius.
With such a small differenece in temperature i noticed that peltier alone is able to output around 70mV by connecting to multimeter.If you are living in a cooler country then the temperature difference between your body and room temperature would be greater hence peltier would able to produce more power.
My joule Thief boost the tiny voltage to a usable voltage with the possibility tricke charge any portable device.The open circuit voltage from my joule is 8volts output for 50mV input at around 4mA current draw for input.

The peltier could be strapped onto wrist or place into hat for example.

I have posted my Ultra lowest 25mv self starting Joule Thief circuit in youtube under user "sanjev21"

Very nice but i think a small solar panel gives you much more free energy and you can store it in a battery so you can light the led 24/7.

nice work!

may i suggest something?  take 2 peltiers use one to generate power and use the other to heat, and put them back to back. ie: so the one generating power is feeding its power to the one generating heat. place these both in a well insulated box that you can place a 'bootstrap' heat source in, like a small coal or a hot rock.

i added a led bank to the first one of these i built and used a lm7812 to control the voltage being applied from the one peltier to the other. you can apply this same principle to heat and light a small, well insulated shelter/shed. of course, you need a few peltier combos to do this, but it does work... i have done it. around here the temperature differential between inside and outside can be as much as 70 degrees F... i simply put peltiers in the walls, with one side exposed to the elements.

you can capture solar energy during the day to create a 'bootstrap' temperature differential, or as scratchrobot noted, you could use a solar panel to charge a battery and apply that to the peltier that generates the heat for a 'bootstap'. there are lots of different possibilities for 'bootstrapping'... an earth battery could be used, a simple windmill or a hand cranked generator. just use your imagination!

again, nice work!

What if there was no sun or charge at the time of need when its dark?  ;)

I think its a great idea. And the small difference in temperature that Mag is talking about is small.

Very nice.  ;D

You are right and i agree very nice idea and build  :)

Hi magpwr,
Nice idea, i too would like to experiment with peltiers, can you try and put a heater coil from the output of your jt to the peltier, and see if you can loop it with its own power?

Hi,

We can use external heat source but it will defeat the meaning of "Free energy" which my circuit was intended for .Circuit output can't generate enough power to heat peltier again.
Peltier are only 50% efficient if used as a cooler.

Although there could be another possibility like using "crystal radio" to tap into "natural radio wave" and broadcast radio wave which may produce in milli volts to power my circuit to boost voltage
to useable level.

I did not even notice the 25mv, that's very low!
I also have a Peltier somewhere lying around and maybe i can power my crystal with it, your idea to tap into some wave is also nice.
Can you tell me why there are 4 fet's in your circuit?

Thanks

Have you looked at the JT threads? Where gadgetmalls jt circuit 1.5v AA battery can light modified cfl's, christmas lights etc...if your jt is like that maybe its posible?

Hi,

To Crazycut06,
This joule thief could output around 30v at 1V input. But my version 1.0 joule thief is design for low power/current.

I have already created a high power version but i realise peltier can't produce high current at such a low voltage like body heat.

If you are talking about "ultimate high power joule thief" to run from battery down to below <100mV .Yes it is already made &tested but still in improvement stage.
But that  is reserve for  future  posting version 2.0 but input current is higher at 150mA . I have also created version 3.0 which have certain improvement over 2.0.
The toroid remain the same in any case.

To Scratchrobot,
The reason why i am using 4JFET in parallel is to increase current output.Using 1 fet current consumption is only around 1mA and obvioiusly the output current is lower.THE jfet was not design to handle high current.

So I could also use just  one jfet with higher current rating and the result would be the same?

To Scratchrobot,

You can use 1 JFet and get lower current ouput.These FET are not design for high current.

You will need to experiment to understand the logic on why i was using 4 JFET.

To cuttinedge2005,

I think you have not calculated all the random possibility before replying to me.

Let me tell you where this circuit could be applied not in urban location where you assume there  is power even during disaster.
 1)Industry application-monitor furance or engine temperature remotely without battery then transmit the information to a central location or control room remotely on interval basis.
2)For military or for hikers out in forested area where is no direct sunlight if you are on the move.
Gps or or other equipment could be trickle charged.
3)If peltier is installed into miners hat.It could serve as permanent emergency light even if the battery pack fails.

Thanks i will as soon i have the jfets. Can you tell me the values of the caps you used because i cant read them in your video.
serves no purpose in the real world.

At least this circuit is working and gives energy unlike most circuits here.
Not everything has to have a purpose.
