NOVELTY - Solar methane battery has methane tank (1), feed port (2), sealing cover (3), heating unit (4), lead (5), temperature displayer (6), temperature controller (7), solar accumulator plate (8) and air outlet (9). The material is injected to the methane tank from the feed port arranged at the top of the methane tank. The sealing cover is closed. The solar accumulator plate generates electric energy. The temperature displayer displays temperature of the tank. The methane generated by the tank is released in air by the air outlet arranged at the top of the methane tank.    USE - As solar methane battery.    ADVANTAGE - The battery has simple structure and reasonable design, and is environmentally-friendly. The battery utilizes energy reasonably and the rate of methane generated is controllable.    DETAILED DESCRIPTION - Solar methane battery has methane tank (1), feed port (2), sealing cover (3), heating unit (4), lead (5), temperature displayer (6), temperature controller (7), solar accumulator plate (8), and air outlet (9). The material is injected into the methane tank from the feed port arranged at the top of the methane tank. The sealing cover is closed. The solar accumulator plate generates electric energy which is transmitted to the heating unit in the methane tank by the lead on the temperature controller. The heating unit emits heat. The temperature displayer is positioned between the temperature controller and the heating unit displays temperature in the methane tank and the temperature controller controls the rate of methane generated in the methane tank. The methane generated by the material in the tank is released to air by the air outlet arranged at the top of the methane tank.
