The purpose of this work
LENR - Low Energy Nuclear Reactions - Cold Controlled Nuclear Fusion is a phenomenon that, despite numerous positive experiments around the world, official science continues to deny. Therefore, it is still important to propose a simple and easily reproducible experiment proving the existence of this very relevant phenomenon. The installation proposed here should register the phenomenon according to its three manifestations: excessive heat generation, transmutation of the environment and signs of "strange radiation". A little-studied process of diaphragm discharge in distilled water is used, when plasma is excited between liquid electrodes in the holes of a silicon diaphragm.
