Update: just tried tap water with 2 car 12 V car batteries as input. Output increased as did the amps. With 25 V input the Amps sky rocketed to 10 Amps!! Unbelievable if you compare to a normal HHO cell with electrolyte!

This HHO cell will beat anything on the market, mark my words.
Now we tried to estimate the output at 3V input and 0.3 Amps(input 0.45 Watts). The output looks like at least 50 ml gas output per minute(0.05 lpm).
I have hard 1 lpm equals 60 Watts output.
That means output is 0.05*60 = 3 Watts
Input is 0.5 Watts to be on the safe side
COP is 6 according to this. First we estimated gas flow to 0.1 lpm and halfed that estimate.
Now we are CONVINCED this is OU by all means despite the "farmer solution"(or thanks to it). Vibration is amazing.
We will measure gas flow more accurately soon but preliminary indications are this is easily OU.
