I am using a common kit to produce HHO and am curious how it compares to other systems. I have calculated efficiency based on watts per liter per minute. With my current 48v system I am producing 15LPM at 45A giving me 144w per lpm. So far I havent found a better kit than the ones at DrFission.com but I am curious to see if anyone is getting a better result than 144w/lpm. Does anyone else use this method for calculating efficiency? Does anyone know of a reactor that can produce a liter per minute at less than 144w?
