Date Mar. 3, 1994To provide a power generator capable of replacing thermal generators, which is capable of realizing large amounts of power at low cost while using almost no fossil fuels and without polluting the environment. A solution comprising a solvent, which itself does not dissociate, having added thereto a substance which dissociates in the solvent, stored in the interior of a container having an inner surface possessing corrosion resistance and insulating properties, wherein an anode electrode having a small work function and a cathode electrode having a large work function are immersed in a mutually opposing manner in the solution. A power generator comprising: a container having an inner surface possessing corrosion resistance and insulating properties, a solution comprising water added to anhydrous hydrogen fluoride, stored in the interior of the container so as to be isolated from the atmosphere, an anode electrode comprising a material having a small work function and possessing corrosion resistance, a cathode electrode comprising a material having a large work function and possessing corrosion resistance, and a heat application mechanism.
