ABSTRACT

In the past few years the studies of the solid state nuclear reaction have made a rapid progress.  In the course of these studies the term of “Nuclear Transmutation” is becoming essential in this field nowadays.  Of these, a new technique of so called “Plasma Electrolysis” using tungsten and rhenium electrodes developed by ourselves allows the production of large amounts of excess heats of 100 W order, corresponding to 150-250% of input energy.  The technique offers a very promising prospect for the construction of a commercial level energy device utilizing nuclear transmutation.  In this text, the technique of the plasma electrolysis and the results of the excess heat measurement and the analysis of product elements as well as the latest important results obtained in other laboratories will be described.
