have to tried not covering the internel electrode with anything if so what happened

Had you asked this question last week I would have replied that I think the separator is absolutly necessary. Yesterday, for grins and giggles, I tried a different cell type that was not using a separator and it worked, although very poorly. I will give this cell type a try without a separator when I can get back into the shop.
Thanks, Brad S

I would love to duplicate your work and have one running 120+ hours too.

Many thanks,

Fausto.

Please share, I would love to see what you are doing.

Hi Brad
How much voltage did you get without the seperator? I haven't had a chance to work on any projects my parent's house was flooded due to the rain and thaw. But I hope to jump back into it this weekend!!

Sorry to hear that. Hope everyone is safe and no permanent damage.
The separator is an absolute must in the type cells I am building. I tried a quick test last night with conduit and carbon - no separator. The voltage was 0.09v.

Observation: @all - please respond with your thoughts.
The magnesium carbon cells powering my little solar lights, Old one sealed using Epsom Salt and the new one uses plain water. The plain water cell seemed to be dropping current faster than the Epsom Salt cell. A wind driven rain fell yesterday and rain-water got into the plain water cell. Last night the cell gained strength and the morning the cell light was brighter than when I made it. Why would rain-water be better than tap-water? Any thoughts?
