In a nearly random search to find more supporting data for the idea of the much maligned energetic overunity in the Production of combustible gases from aqueous solutions by means of plasma arcs, akin to what can is doing in some of his experiments, I found this European Patent filed in 2001 and granted in 2013, near to expire in 2021, which lists Ruggero Maria Santilli as inventor but a wide array of companies as patent owners (depending on the country).
I was under the impression that Santilli had lost most of his battles to patent this seemingly impossible aspect of his inventions, at least by currently widely accepted scientific knowledge, so it was quite a shock for me to see that he obtained a patent for it, and that is about to expire.
Over-unity production of clean new energies by recycling contaminated liquid waste
Reactors (108) for the total recycling of contaminated liquid waste, which produce a clean burning combustible gas, usable heat, and solid precipitates, a main feature being that a total of the available energy in the combustible gas and in the produced heat is greater than an electric energy needed to operate the apparatus. The latter feature is called commercial over-unity, and essentially establishes the capability of the new reactors to tap energy from the liquid molecules in full conformity with the principle of conservation of the energy. Different embodiments include the over-unity recycling of automotive antifreeze and oil waste, a new method for the production of a fuel from crude oil, for desalting sea water and for recycling biologically contaminated liquid waste, such as town sewage, into a clean burning combustible gas, nutrient rich water useful for irrigation, and soiled precipitates useful for fertilizers.
