ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a method and apparatus for converting natural heat energy into another form of energy, more particularly to a method and apparatus for transmitting natural heat energy, such as solar energy or geothermal energy, to water held in a tank of a steam boiler so as to convert the water into steam for further conversion into electrical energy.
2. Description of the Related Art
while solar and geothermal apparatus are available in the art for heating water, they lack the facility to convert solar or geothermal energy into another form of energy effectively, such as electrical energy.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a method and apparatus which can transmit natural heat energy for heating water held in a tank of a steam boiler so as to convert effectively the water into steam.
Another object of the present invention is to provide a method and apparatus which can convert effectively natural heat energy into electrical energy.
According to this invention, the method for converting natural heat energy into another form of energy comprises the steps of: (a) exposing one end of a superconductor body to a source of natural heat energy; (b) inserting another end of the superconductor body into a tank of a steam boiler that holds water therein, whereby the natural heat energy is transmitted by the superconductor body to the water held in the tank of the steam boiler so as to convert the water into steam; (c) providing the steam from the steam boiler to a steam turbine to produce a mechanical rotary motion; and (d) converting the mechanical rotary motion into electrical energy via use of an electric power generator that is coupled to the steam turbine.
In another aspect of this invention, the apparatus for converting natural heat energy into another form of energy includes a steam boiler with a tank that is adapted to hold water therein, and a superconductor body which has one end adapted to be exposed to a source of the natural heat energy, and another end inserted into the tank of the steam boiler. Therefore, the natural heat energy is transmitted by the superconductor body to the water held in the tank of the steam boiler so as to convert the water into steam. The apparatus further includes a steam turbine which is coupled to the steam boiler so as to receive the steam from the steam boiler and produce a mechanical rotary motion from energy of the steam. An electric power generator is coupled to the steam turbine for converting the mechanical rotary motion into electrical energy.
