Introduction: For marketing and selling their products, water-treatment equipment vendors use commercial iron and aluminum electrodes thereby changing the quality of water and increasing soluble and suspended solids in water. Due to the lack of scientific justification for the creation of sludge and discoloration caused by water electrolysis with commercial electrodes, this study aimed to compa...

Background and objective: The conventional chemical and physical methods for water disinfection include the application of ultraviolet (UV), chlorination, and ozonation. Water disinfection by electrochemical methods has been increasingly carried out recently. The goal of this applied - analytical research is to investigate the removal of E. coli bacteria, as the index of water microbial contami...

Pre-electrolysis at the boiling point in open Pd|D2O cells is an effective method to activate a palladium cathode, which can produce excess power in subsequent electrolysis in closed systems for several months. The reproducibility is 23/45. Another characteristic of excess heat is the apparent resistance of electrolytic cell changes irreversibly with temperature.

This review makes the case for cheaper and more efficient water electrolysis technology. In particular, the potential advantages of zero gap, alkaline water electrolysers based on hydroxide ion conducting membranes are highlighted. Following a brief introduction into the thermodynamics and kinetics of water electrolysis, recent developments in oxygen evolving anodes, hydrogen evolving cathodes ...

Samples of palladium sheet supplied by IMRA Japan were tested for anomalous energy production using electrolysis in heavy water and a sensitive calorimeter. Several samples were found to produce significant power above that being applied to produce electrolysis. This behavior was found to correlate with certain properties of the palladium metal. In addition, the anomalous heat was shown to orig...
