I built an 8 plate dry cell running on a 12V 6A trickle charger. I'm getting almost no HHO. Some little bubbles with 1 or 2 slightly larger bubbles a minute. I put a water balloon on the end and after an hour, it inflated the water balloon a bit, but didn't start to stretch it. I added a drop of Drain-O as an electrolyte.
What am I doing wrong?
Thanks for any help!
