PURPOSE:To convert low-temp. heat energy into electrical energy with good efficiency. CONSTITUTION:Polyethylene glycol is stored in a tank 11. Ion conductivity- providing salts are added to the polyethylene glycol. A plurality of positive electrodes and negative electrodes are arranged alternately in positives and negatives in the polyethylene glycol. Each positive electrode is formed of graphite or a graphite composition. Each negative electrode is formed of a metal such as zinc, copper, iron. Its surface is formed in a recessed and projecting shape to expand its surface area. The polyethylene glycol in the tank 11 is sent to a heat collector 20 by means of a circulating pump 21 and is heated up to around 90 degrees C, using solar heat or warm water drainage and is then returned in the tank 11. In this case, air in the atmosphere is sucked by means of the circulating pump 21 to blow in the polyethylene glycol to circulate the air-mixed polyethylene glycol having a temp. of around 90 degrees C in the tank 11, providing power generation like a kind of fuel cell. |
