Paul uses sims a lot. He used some to make fine adjustments to his research meter. I used some simple SPICE DC circuit analysis to see how efficient diodes are at low power levels. I think a massive parallel diode grouping will do all that's necessary to rectify and aggregate Johnson noise. Paul believes that complex element arrays are needed. Paul believes that diodes should have high saturation current; I believe that good diode forward / reverse discrimination requires a low Is. He found the SMS7630, I searched that family and found the SMS7621 with lower Is and a little lower junction capacitance. I believe that there is room for everyone when the diode array emerges from obscurity. I would appreciate more scientific peer attention on http://www.steorn.com/forum Diode Array: Ambient Heat to Electricity.
