Nikolai Zaev Repro. Ambient Temp to Energy Conversion
« on: June 01, 2010, 05:04:26 PM »
I had read this paper some time ago on the conversion of ambient temperature to heat via the use of toroid transformers:

http://www.intalek.com/Papers/zaev1.pdf&pli=1

And then during the Steorn replication frenzy, I saw that some were reporting cooling in their coils during operation (Ossie?).

Recently I saw this on eBay:

http://cgi.ebay.com/High-Mu-Ferrite-Toroids-qty-100-/360247355568?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item53e06a68b0#ht_500wt_1154

And purchased 3 lots of them.  As it stands, they do indeed have a quite high permeability (15k-20k?), although they themselves are quite small.

I wound 10 of them bifilar with 26# AWG copper wire.  I wound the primary in series and the secondary in parallel.  I know the reproduction isnt a reproduction as I'm not following his setup, it was the same principle I just wanted to look at.

I've been pulsing the toroids primary with the same setup I'm using in the other thread from the same battery, which started at 11.31 volts yesterday at 5pm.  I'm taking the secondary output and rectifying it with four diodes and dumping that back into the battery.  I'm also using a flyback diode on the primary coil to redirect the voltage spikes back to the battery.

It is 8am this morning and the battery is at 12.1 volts

Two things.  First, to get the output waveform that is charging the battery, it needs occasional adjustment as the battery charges (I'll take shots later today after work).  And second, I also fear this may be a result of leeching power from the function generator as was suggested with gotoluc's tests for his self running coil.  I suppose the next step would be to set up a circuit with a PWM that is also powered by the same battery.  Fortunately I bought a few LM494's on eBay awhile back so that's easy enough (I have plenty of 555's as well).

Has anyone else tried replicating the effect in this paper?

I tried this with ferrite cores that had a u = 4300.
It was a no go for me.

Can you show your switching circuit?

B.t.w. if you read the article carefully you can see that a noticeable temperature effect is not likely to be detected.
The heat capacity of ferrite cores is simply to high.

Yes, it will have to be later today however, I need to sketch up the circuit for the other thread as well.  I'll post it tonight.  I'm very much an electronics rookie, I mean I just learned what a flyback diode is for (after burning up a $150 lab power supply of course). :)

Maybe it just has to be highly permeable cores - I think he says he's using permalloy cores - these would be tape wound right?  The cores I picked up off eBay look to have u > 15k.

Yes, you might be right.
I'll post another publication by Zaev on this tonight, which contains a table of different cores he used and his results on this.
I don't have this article available here at my office right now.

Thanks, I appreciate that - my google skills have been failing me at finding further information about his testing.  Up to 12.14 volts :)  I dont know how much of this can be due to the mosfet capacitance - I'm using the IRFS820 @73KHz.  Actually have to go adjust the freq again, the scope is showing the output flat lining - seems as the voltage increases I have to nudge the pulse width to get the pattern back.  Maybe I'll go snag a couple quick photos (I really need to get some work done lol).

A few pics - seriously getting to work now.

Would you happen to have a clearer picture of his circuit - the one in the PDF I linked, I cant make out some of his values.

I have a printed version that shows details of the components.
Let me know what values you want to know and I'll have a look.

Attached is the second article on this subject from Zaev, published a few years later.
He even published his phone number (on top of the paper).

Thanks for the details you posted until now.

I'm not panicked, but mildly horrified, I glance over my shoulder occasionally to monitor the setup, and I see after my last minor adjustment the voltage has now dropped to 12.08v - It didn't strike me that minute fine tuning would be important.  I'll have to get more precise later with exactly what is occurring.

I scanned my paper version and cropped the figure.
See below for component values  ;)
