What do the pro's use for HHO generation? They have 110V machines that put out specific amounts of HHO and I would be interested if anyone has seen the inside of these tried and true machines. I've got my 316 .031" SS and plan on mounting it in a polypropylene 3/8" container that is slotted to fit three sides of my plates. The top will stick up out of the water so there won't be any stray voltage. Now I'm just trying to figure out the proper spacing. Seems like everyone is going with extremely close spacing. I probably can't get my slots closer than 1.5 - 2.0 mm.... Then I'll be able to easily test different electrode setups and spacing designs. Any thoughts?
