How big of a cylinder style electrolyzer

[GreenEggs]

I managed to get some 304SS pipe. I have:

1x20 inch 316ss
2x24 inch 304ss
3x26 inch 304ss
Still working on the 4 inch pipe. The cutter was gone, so I only paid 1ft values for each of the scrap pieces! All that above ended up costing 34 bucks. the 4 inch pipe is going to hurt the purse however.

I am toying with the idea of having a rather long electrolyzer instead of the standard 6-8inch ones I have been seeing, but I don't have the experience to know the benefits of a 20 inch long 4 cylinder electrolyzer. More surface area would seem to make more hydroxy, but I am not for certain. Anyone know?

Also, would rotating a cylinder style electrolyzer in the electrolyte aid in gas bubble separation? By rotating I mean, spinning the cylinders with a motor to create centrifuge like effect.
