Nikolai Zaev Repro. Ambient Temp to Energy Conversion

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.

I'll post another publication by Zaev on this tonight, which contains a table of different cores he used and his results on this.

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.
