I just had a look at quanthomme and they have a super interesting link.
On the hydroplasma site they managed to overcome the destruction of the electrodes using an electrolyte based on wood ash
So I prepared a hearth ash solution whose recipe is very simple. You fill a third of a bucket of sieved ash, which you fill almost to the edge of very hot water, if not boiling. You stir for a few minutes and leave to settle for at least two to three weeks. Then you filter the solution supernatant the ash. You get a very complex basic electrolyte
I don't know if anyone ever mentioned them in the forum, but it seems super interesting.
Sure, it's not surrunity, but at least it looks "profitable";)
Finally, you have to visit the site to better understand:
