hi everyone,

I have just release one of my sidetracked project and the latest prototype in my youtube channel "sanjev21".
This the first and the only video in youtube release base on DIY project using Body Heat to power up a spinner using a peltier module.

This is also the highest efficiency energy harvesting device which outperform the commercial design. :D
Body Heat to Kinetic -Prototype v2.0 Energy Harvesting device

http://www.youtube.com/watch?v=qDjvQSrOV6c

Please read below to understand what is happening.
-----------------------------------------

After few years of current topic idle it seem certain people are charging high price around $35...$39 base on a prototype design which i have released to public freely merely for replication purpose.
That was just a ver 1.0 design and transformer was merely shrunk using Coilcraft 253P "1:20" SMD transformer.

I have not even bothered to release the improved version 2.0 yet which was already completed few years ago.
It was also a test for me to see if anyone whom is competent enough to improve my released design further.But none seen so far but worst commercialization of my circuit have occured.

You should know who you are.

My intention was free but someone here ruined it for everyone whom simply enjoy circuit building.

QuoteSo,can anyone suggest an efficient,working circuit for me please

Ann Makosinski did use power converter integrated circuit, LTC3108 The circuit contained FET's that would oscillate at voltages as low as 20mV. When used with a recommended   transformer, the IC would provide well over 2.5 volts AC. Such a research here is both reinvention of wheel, both off-topic with respect to overunity.

hi Zephir,

I am using only discrete components and i did mention it produce much higher current output compared to a current commercial unit in my youtube video description.
At 6°C difference i am getting 210uA short circuit current at circuit output.I was trying to prove that my unit is much better than the tested commerical unit which got certain plus points but not in current output.

One of the commercial unit merely deliver 15uA compared that against mine 210uA.There nothing to talk about voltage output around 4volts which is the easy part.Think about it.

Energy given by body as heat is still considered "free energy" where we take "wasted radiated heat" given off from our body 24/7 (If alive) and put it to work.
It's a proof of concept but not necessary efficient.

I am a one man team.

Nothing much to add.

Side story
---------------------------------------------
Electrical power for the New Horizons mission to Pluto is furnished by a single radioisotope thermoelectric generator (RTG), which transforms the heat from the natural radioactive decay of plutonium dioxide into electricity

This is still too low - Ann Makosinski (a grade 10 student) got for 50 mV DC from the Peltiers about 6 mA at 5 Volts AC which was sufficient to light the LED. The result was a bright light at 5 degree Celcius of Peltier differential. Yours 210 uA is still at least ten-times worser result. On the web you can find Joule-Thief circuits with silicone (or preferably germanium) transistor in common base configuration, which is capable to oscillate at ~ 30 mV only.

I feel sorry that your design has been stolen - but I'm afraid, it will not work anyway so effectively like the professionally designed integrated circuit mentioned above. Environmental or waste energy recycling isn't overunity, which this forum is all about. Your device still consumes an energy and given the amount of electricity produced the crank dynamo powered battery would be way cheaper solution. Try to replace the lithium battery in ultracheapo crank dynamo flashlight with supercapacitor - and I can assure you, you'll be pleasantly surprised with result.

hi Zephir,

Since you wanted to debate with me i shall prove 2 things since you wanted to compare me with the little girl.

Firstly the video of mine was released for members in overunity  to replicate on 20th Dec 2012 -Ultra lowest 25mV self starting Joule Thief ver1.0-Free Energy.
-Using single peltier module

The girl video was released on 30 Apr 2013 - The Hollow (Thermoelectric) Flashlight - Google Science Fair
-Using 3 peltier module.


The commerical version "allow short burst in mA" for RF transmission purpose.

I do challenge you or if you can get anyone to try using LTC3108 to "immediately power up the display spinner" at 6°C difference and not in burst after few seconds charging capacitor. ;D ;D ;D

Since i already mentioned mine is better than the commerical unit in output.But Commercial unit got more feature like "supervisory circuit built in".

Yes peltier is not a efficient way to generate electrcity only this i agree from the start.

Yes my device is able to self oscillate at 15mV but i am interested in more power output.

Think about it if every kids use the factory design components then where is the learning curve.No basic foundation is that what you wanted for the future. :D
