Energoniva (Энергонива in Russian) technology is typical Russian invention of postSoviet era with all its pros and cons. It passed lenr-forum unnoticed, it has no page at Wikipedia and even YouTube search doesn't return any info in English. All relevant information you can find therefore exist in Russian language only. But I believe, it deserves a close attention of the Western world - because if it would work, it could make our Universe a very comfortable place to live. The Energoniva technology has been developed in 1994 - 97 years in formerly closed industrial city Magnitogorsk with two scientists: A.B. Вачаев (1936 - 2000) and Н.И. Иванов (16.12.1924 – 19.03.2010) (A.V. Vachayev and N.I. Ivanov in common transcription). The original research lab has been already closed in 2010 and the best available info about it you can find on the web is here.
The principle of Energoniva technology is very simple and it consists of transmutation of water in plasma discharge. The simple experiment should demonstrate, that this technology work, if you discharge the high voltage (2 - 10 kV) capacitor with copper electrodes attached beneath surface of water. Usually a black cloud of suspension gets formed and you should be able to prove the formation of iron, manganese and many other elements in it. But Vachayev managed to control the reaction in continuous arrangement in high-frequency plasma arc. And not only this - he managed to recycle most of electricity input, so that the reactor produced energy in self-sustained mode in similar way, like the SunCell reactor of Randell Mill. After all, both technologies could have many things in common. Vachayev was able to produce quite remarkable amount of metallic dust, which has been later smelted into an ingots and analyzed in bulk (see the picture above).
