Wikipedia:Articles for deletion/Hydroelectric cell
I tagged this as a hoax in September 2020. I now believe that this is a simple galvanic cell with a slightly novel form of electrolyte. It is certainly not notable and I don't believe it warrants any mention in :Galvanic cell until it is demonstrated to be a useful and practical device in significant use and with reliable sources outside of academia reporting on novel findings. Fails  by a very long way.  '''''&nbsp
