Have you ever seen my "orbonbon' ? lol  It is a solid state orbo. The first actually.

I named it all funky because of the way you named the orbette. It was just the thing to do at the time. ;]

I have a long ferrite toroid, the kind that is used as suppressor on computer monitor cables, wound as a long toroid, neatness inside was critical because magnets go inside, and I have a pickup winding wound around the diameter.  We insert the stack of 1/4x1/8in neos on the core. The N and S poles are attracted to the core, so most of the flux is in the core and within the inner side of the pickup coil.

When we energize the toroidal winding, the core goes into the Orbo effect, and the magnets field is released, and their lines of force cross the pickup coil causing current to flow. Then when we release the toroid coil power, the flux crosses the pick up again causing current in the opposite direction.

This is as a whole is inserted into a larger set of toroids as seen in the vid to contain the expanded field of the mags beyond the pickup coil when the orbo effect is engaged. So the flux switches back and forth from the inner core to the outer core, and generating currents in the pickup along the way.  ;]

I have several vids on it. This was the last one I did.

Ok, just watched my vid, its been a while, and this vid doesnt use the outer core. The previous vids to that do.  It works wither way.  there were reasons for and not.

How to make thermoelectric generator without thermocouple module or peltier cooler I mean direct conversion of heat in to electricity with some material parts

Anan, do you mean you want to make your own module instead of buying one? They are not expensive.  ;]


Here is a pic of the SS A/C unit.

I used to see those modules in surplus places all the time for a decent price.  I have not seen any for a while now.  Do you have a good source Mags?

Hey Bill

These are larger than the one I have. I remeasured the current of the module I have and it is 3 amps not what I said earlier. Had not fired it up in a while. ;]  These are 6amp.

http://www.ebay.com/itm/2x-TEC1-12706-91-2W-TEC-Thermoelectric-Cooler-Peltier-/150471454617?pt=LH_DefaultDomain_0&hash=item2308cc2f99

The same in bulk, just a bit cheaper.

And here is a big boy. ;] 400 watt up to 26 amps

Im sure there are many sources out there.

Here is a bad example on ebay. It apears to be 1 module, for just over $1k   :o And they probably occasionally hook a sucker on that too. ;]

hey bill, good to see you around...

www.tegpower.com is another option.  interesting side note regarding them; when i watch their youtube videos, that guy sounds an awful lot like a certain dr. stiffler...

Thanks for the link.  Yes, he does sound like the good Dr....ha ha.

Good to see you too.  I hope all is well with you.

I ordered the 400 watt  device from the link that Mags posted above.  This should be fun to play with.

I built a second thermogenerator with the two Peltier elements I had from my first build.

Two such elements http://uk.farnell.com/multicomp/mcpe-127-10-13/peltier-cooler-38-1w/dp/1639751

The output is not better than with my first try (see at the beginning of this thread), it is about 80 mA at 1,3 Volt (about 0,1 Watt) with two candles. I tested and measured the thermogenerator with a Joule Thief circuit driving a 1 Watt 220 Volt Led bulb.

The cold water container holds about 2,5 Liters (evacuation tube with a diameter of about 110 mm, length about 320 mm.

See the attached photos. To go any further I have to order bigger elements which are capable of handling higher temperatures of up to 250 Centrigrades.

Greetings, Conrad

Hey Conrad

The 80ma 1.3v , was that on a load?

Can you show what you have there? Its hard to tell what is what other than some heat sink, water bucket and wires.  I just want to see how the heating and cooling are done here. It might be better to have the element on the side of the container, with the candle burning under fins of a heat sink, with a thin metal shield to help hold the heat in that area.  And the rising heat wont heat the water unnecessarily more than the cold side of the chip provides it. A vid i saw on YT the guy had the candle burning right under the bare chip, with a fan and sink on top.  Ill see if I can find it.

Thanks for showing

Are you using 2 chips here?  If so, the 2 chips will transfer more heat to the water, there by keeping the 'hot' side colder, thus less output.

If you just use 1, and get better results, then what you need for 2 is 2 candles. ;]

I received my 400 watt unit the other day.  I also got another smaller unit that has no specs I can find.  The only thing i did was hook one up to an old AA battery just for fun and...one side got really hot and the other very cold, very fast.  The 400 watt unit is rated at 12 volts input.  Probably designed for the coolers.

As soon as I get a chance, i will add some heat sinks and see what kind of power I can get from these units.  I know they are not supposed to be very efficient but, the concept is very cool.  Just another fun thing to play around with.

Hey Bill

Thats a huge one.  ;]  Its like 10 times the power that mine, from a 6pak cooler. I dont know what they use those for. Big fridge.  Da Big Freeze.

I never tried a AA on one. ;] Sounds good for testing. Cuz 12v with the chip between the fingers, ya might get burned and frost bite. Seriously. Not a toy. ;]

Just be sure to have heat sinks that make contact with the whole surface of  the module. Portions that are not in contact will get very hot or cold, wasting what your trying to accomplish. ;] And maybe hurt the module with hot spots. A flat bare of copper or aluminum then ad sinks with fins.
