@Steve, I use 50% duty cycle so that means 3V*0.3 Amps*0.5(50%) = 0.45 Watts input

But I made an error on the HHO energy content. 1 litres of hydrogen holds 7744 Joules(?) of energy as far as I ahve found out. That means about 125 Watts effect for 1 LPM hydrogen. Assuming our HHO has the same(!) energy content as "normal" hydrogen that means we can at least double my calculation again(COP 12).

However, I believe I might have exaggerated the output despite all(most bubbles at 3V are very small and it is hard to estimate their volume) so let´s assume COP 6 for now anyway. At least we can get OU that is or sure.

Chris Eckman wrote an article where he measured 1 LPM HHO to generate more than 700 Watts, which I don´t believe..... Let´s not get excited.

We will measure gas flow(which is hard) soon.

And yes you are right, AMPS lowers the efficiency(normal electrolysis will always diminish our COP) dramatically but the effect is cool(after 3 seconds you run...).

I maintain this phenomena is truly an interesting proof of concept but holds little industrial value.

However, if you understand what this HHO is and then mix it with positive water mist and neutral water mist, then you have the water ion engine à la Meyer, that is where we aim. This is the first part and it is always the hardest.

I recommend anyone near Arizona to go to Teslatech 2009 and see Chris Eckman about Brown´s gas, or buy the hard copy of the latest issue of Extraordinary Technology.
