A PWM circuit and fresh water or a more standard electrolysis setup? The more standard approach being DC voltage applied to water with an electrolyte to promote conductivity. Not being critical here; anybody who’s had the ambition to actually go out and try it is good in my book. X:X Running leaner will make better mileage and I wonder if that’s where the efficiency is really coming from? I don’t really know. :idunno:
Jay, I’ve got some diodes, some Shockley’s if needed, resistors, small DC motor, some FETs, and said hammer. Now what?
