I was looking for resonance drive unit info today and thought this looked if anything interesting.They say(you what that means ) it will produce over 15 lpm,but the amps run around 200 .Said it took a minimum alternator upgrade output of 250 amps and adding a trolling motor battery.If anything its got a cool bubbler using baffles to keep the electrolyte out of the motor.
