Jeff, Look at figure 9 on this page: http://www.rexresearch.com/godes/godes.htm
Two cathodes are shown. It almost looks like the "2" cathodes are connected together at the bottom. Is he running the Q in a loop through this, and the loading pulse through the anode do you think? Here is some support for the idea. In this paper ( http://newenergytimes.com/v2/conferences/2012/ICCF17/ICCF-17-Godes-Controlled-Electron-Capture-Paper.pdf -- bottom of column 1 page 1), he says, "High voltage, bipolar, narrow pulses were sent through the cathode and separately pulse-width modulated (PWM) electrolysis through the cell (between the anode and cathode)." So, looks to me like he loops Q through the cathode and the DC loading pulse comes through the anode through the cell to the cathode. Also, are you suggesting that his alternating current is alternating DC current (never goes to truly negative voltage)? Thank you for the caution. I will research and be careful with this.
