To provide home use electric power with a compact device by putting quartz, feldspar, and silica rock in a steel container together with water, heating them, and receiving energy generating from silicon.

Quartz, feldspar, and silica rock are put in a steel container 1, a battery 2 is connected to a preheating nichrome wire 7, and water 10 is filled in the container 1. A preheating switch 15 of the battery 2 is turned on, the container 1 is insulated with a mica insulator 8, the temperature of the preheating nichrome wire 7 is set to 85°C, energy of ores 9 of quartz, feldspar, and silica is drawn out, and water 10 is heated. The temperature of a thermometer 11 is set to 85°C, -electrophilic sensor 5, and + electrophilic sensor 6 are floated in the container 1, and an electric lamp 18 is lit though an electrode board 13, an IC 14, a female switch 16, and a male switch 17. Since electric power is generated with the battery 2 and ores 9 of quartz, feldspar, and silica rock, no environmental pollution such as radioactivity is produced, and construction and operation are made simple.
