@wings: It is of course well known to use Peltier Elements as a power source (in combination with fire).

I did some experiments, see http://www.overunity.com/12607/thermoelectric-generator-candle-and-cold-water/#.UPU9BGckQfw .

Usually one needs a big temperature difference (e.g. 100° Celsius, better more) between hot and cold side to draw some useful energy from a Peltier Element.

The new (and for me interesting) feature of magpwr's circuit (and the discovery of the 2SK170 transistor) is the fact, that very small temperature differences (e.g. 10° Celsius) can make a LED glow with a Peltier Element.


Eventually it could be interesting to charge a small 1.2 Volt accumulator with a small temperature difference (without fire, just natural temperature differences e.g. between water and air, or air and ground). Not a world saving thing, but nice.

And in itself, it is interesting, that one can make a LED glow starting with about 50 mV. The big event (for me) is the discovery of the 2SK170 for the Joule Thief type circuits, bringing the Voltage down to 50 mV (which I never saw before magpwr's disclosure).

Hi Wings ,conradelektro,

Thanks for showing me the thin film peltier  i have done research on this thinfilm version around 1 or 2 years but didn't know where to buy those.Maybe at that time it was just at discovery stage.

Thin-film peltiers
http://www.nextreme.com/

I will not use buy those thin film peltier yet unless i'm focus on making circuit and everything else tiny. 

My next investigation  might or might not be "overunity" which remain to be seen/tested yet.This is what i have in mind base on an old discovery which i accidentally discovered around 4 or 5 years ago.

This is my long story short how i accidentally discoverd something of interest-
You see i love upgrading pc along with graphics card once every 2 years since i love playing games for max 2hours to keep my mind\cpu working at top speed.

I wanted to try a different kind of cooler available in market at that time.The cpu cooler i purchased uses a liquid/gas to cool the CPU. The gas used is Tetrafluoroethane-1,1,1,2 (R134A).
Please check the link to see how the cooling effect works.

This is my discovery i took the  "VapoChill Micro" by hand of course.Since our hand tend to be shaky a little as long as we move.
This is what i noticed by merely moving the "VapoChill Micro" a little i noticed the base of cpu cooler getting really cold and also noticed "water condensation taking place quickly at the base".

Please take note i'm living in a tropical country where the temperature remains at around 30 degree celsius throughout the year ,+- 3c difference max.
I did not have those remote temperature monitor around 5 years back.But my guess is base on speed the water condensation taking place in matter of few seconds on gas based cpu cooler might be  around 10 or 15 degree celsius cooler than my room temperature.

That's all for my discovery part.
-------------

I have an idea which might generate "overunity" if it works.If we were to place peltier beneath the gas base cpu cooler(cold) and heatsink is place one side peltier to obtain hot temperature from my room(hot).

Place the (cpu cooler with peltier with heatsink under the peltier ) onto something that it will rock this unit to and fro or left to right easily.Since we now know that this gas base cooler is  really good at "losing heat" for whatever reason.
I'd believe we some of us have seen commercial unit sold as decor or entertainment visual unit  where it just move left to right maybe with 1 battery or solar.I have no name for it at the moment.

Since we know peltier could definately generate electricity by temperature difference generated especially from rocking motion(gas cpu cooler) against my room temperature 30c.
We take that electricity from peltier to power the rocking motion coil via the 25mV joule thief.As the unit moves left to right for example gas cpu cooler gets even cooler.

This is just theory to generate electricity on infinite basis with no further human  intervention.It really depend on peltier efficiency among other thing eg:design.

@magpwr and all OU by cooling fans:

Look at http://en.wikipedia.org/wiki/Heat_pipe , it describes the principle behind "heat pipe cooling".

About the shaking: according to my understanding, the "shaking" of a "heat pipe cooler" is a one time option. The droplets which have formed at the top of the heat pipes are shaken off and drop to the bottom, where they evaporate and cause noticeable cooling. But once all droplets have fallen, it will take a long time till they form again (at least minutes). And it does not matter whether all the droplets fall at once (by shaking) or fall off one by one (cause by gravity once they become too big for adhesion) over a longer period.

So, let's say the air flow through the cooler is such that the droplets form within 1 minute. Now, we can shake off most of the dropplets at the end of each minute by hand. Or, we can let the thing be and the droplets fall slowly over the whole minute. In both cases the dissipated heat will be about the same.

I see no OU effect. The dissipated heat depends on the air flow (e.g. Litre per Minute) through the heat sink (laminates) and on the temperature and moisture of that air.

The advantage of a heat pipe cooler (pipes in a laminate, without compressor) is that it can be smaller than a conventional heat sink (laminates, without the heat pipes). This is practical, but not OU.

Let's say we move 100 Litre of air through a conventional cooler per minute. We have to move the same 100 Litre of air through the heat pipe cooler per minute, but the air will have to move through a smaller space, which means we need a bit more fan energy, because the air has to get a higher speed (in order to press the same 100 Litre per minute through a smaller hole). So, the heat pipe cooler even needs a little bit more energy for the fan than a conventional cooler. But roughly speaking, they need the same fan energy (at a given air temperature and moisture, and cooling down to the same temperature)

The next OU hurdle is the efficiency of Peltier Elements. The best Peltier Elements have an efficiency of 7%. So, the cooler would have to be at least 15 times OU.

Having ranted against OU, I am still convinced that a "heat pipe cooler" can be a big help when using a Peltier Element, because the cooler can be smaller, which is practical. And the size difference is big. And a "heat pipe cooler" can cool down to the melting point of the working fluid (a conventional air cooler only down to air temperature).

My humble low tech design: A platform (big or small, depending on the money you want to spend) floats on a lake or river. On the platform are many Peltier Elements arranged like ceramic tiles on a floor in a horizontal plane. The hot side is above and carries big heat catching laminates through which the wind pushes the rather warm air. The cold side is below and carries a heat sink (laminates) reaching deep into the water. Water in a lake is colder the deeper one goes down, water in a river might be cold because it comes from the mountains. This works day and night, as long as the air is warmer than the water, which is the case in the area where magpwr lives. It is not so in Austria, where the air is easily cooler than the water in winter and even in spring and autumn during a cool night. But one could flip around the platform when the air is cooler than the water. Today the air is -2° Centigrades and the water in the lake is about 8° Celsius (at least 4° at the bottom). So, the flipped around platform would work.

But, I think, going for photo voltaic on the equator is the better option. The best application for Peltier Elements is a Plutonium reactor giving off heat on Mars where the air temperature is minus 90° to minus 200° Celsius (or in space). Small problem, the Plutonium could kill you at least for 50.000 years. So, please, do not experiment with Plutonium.
