The discovery (in my living room) earlier this year of electric potentials higher than the hydrolysis potential, in algae but also in yeast biofilm, is posing the fundamental question:
How come this potential is not causing water hydrolysis directly in the biofilm ? In theory it should, shouldn't it?
So the question is about: how the wave function theory should be used to describe the behavior of excess electron in a biofilm bounded by two electrodes ?
Finally is tunneling effect involved ?
