Hi guys,
I'm new to SG's and having my machine (following Aaron's "complete Bedini SG" handbook almost literally) running since a month now.
My biggest problem - how do I measure more or less accurately the COP?
I went through the spreadsheets out of the Bedini Monopole Group, but wasn't too happy, as they just use ONE voltage for the entire load and ONE for the entire unload circle.
To simplify this complicated item, I used a 12V wall plug with a huge 1F CAP, and measured the current going into the CAP. The Voltage established around 13,9V. So I measured the input current, and the time until I reached the output Voltage of 15.2V. This figure is almost identical to using an analogue Ampmeter in the input line.
For the recharging cycle I have a calibrated system where I can define the discharge current and the "Stop Voltage". To simplify this, I ignore the Voltage in my calculations. All I count are the Amp Hours.
So using this calculation with Aaron's figures from post #19, he uses 0.074 Ah's into his system and 0.050 Ah's out of his battery. Even with a 20 % uplift for the Voltage difference, I don't get a COP > 1. Is anything wrong with my assumptions?
regards
Ralf
