Thank you for your comment.
Well i was looking at this patent.https://patents.google.com/patent/US3114717A/en
Obviously theres differences to the patent and what im doing. But it was a toss up between do i seperate the gas's and wait longer for the balloon to fill up. Or do i sacrifice some efficiency and use a larger balloon and a smaller cell that produces gas quicker.
Obviously im still testing. Iv cleared out a old shed for larger scale tests. Tbh i wasn't expecting the gas output to be as high as it was. Just plain tap water i was getting about 1lt per 3minutes. But hopefully working towards 500ml a minute for urea.
My main goal would be using plain urine as it has the urea and salts needed. But as in the main post. Been having foam issues trapping the gas.
Was thinking of a low protien filter. But im a engineer and metal worker. So im not really sure what is causing the issue.
If you can think of anything which may be causing the foaming. That would be amazing.
Or even better after designing the cell. I was stuck for ideals on how to best use it. Iver it can go no where or it can be used for some good. So id ask everyone if they have any experiments i could try.
