The biggest thing I learned was if you put 2 plates in an electrolyite HHO is produced. No problem. Then if you put 2 or 3 or 4 pairs of plates in an electrolyte and expect to get 2 or 3 or 4 times as much HHO. IT DOES NOT WORK! Why it does not work is anybodies guess. Lead acid batteries have been doing this exact thing for 100 years and they work fine. This is what leads up to the dry cell or in my case 4 spiral wound cells.
