ok, im new to hho (about 3 mos.) and i remember reading something about using a 50,000v ignition coil driven by a pwm to power the cell. has anyone tried this? how does it work? will it work? seems like this would be an easy solution instead of alternator upgrades to power the cells. i am building the first of many cells that i hope to use for multiple projects at home. i am also trying to find out as much as i can on running small (5-20 hp) engines on hho alone. any info or help i can get will be much appreciated. thank you all, this forum is great! and thanks to mike @ hhoconnection for sending me the link..
