Hi, I'm new here and just wanted to post my observation.
I haven't seen an active cooling setup used yet after several hours of browsing you tube, and I searched this forum for cooling but didn't get any results. It seems that heat is an major factor in creating lots of gas, so i was thinking why not set up an active cooling setup using a small pump(a water cooling pump for pc's would work), a tranny/ps cooler(salvage yards are full of them) and a resevoir made out of some pvc pipe and a couple dome caps with the in/out at the top cap and a drain valve at the bottom to drain sludge buildup(it would double as a sediment trap. Basically like this
Reactor>resevoir/trap>cooling radiator behind grill>reactor
It would serve 2 purposes, cooling obviously, but also the reactor elements would last longer because they would always have a fresh flow of cool water that would flush away contaminates caused from the reaction process.
Just some food for thought.
