Patent ID: 6913735

Claim:
A methane/methanol producing system comprising a laser generating device configured to be installed in space around the earth for generating laser beams by sunlight and transmitting the laser beams generated to a predetermined position on land or on the sea, a hydrogen generating unit comprising a semiconductor electrode for receiving the laser beams and generating hydrogen, said semiconductor electrode configured to be irradiated with the laser beams to generate hydrogen by decomposition of water, and a methanol producing unit for producing methane or methanol by synthesizing the hydrogen generated with carbon monoxide or carbon dioxide under high pressure, said laser generating device comprising a plurality of laser rods configured to contain a laser activating substance, said laser generating device adapted to condense and pass sunlight onto said laser rods to generate radiant light from said laser rods by the action of said laser activating substance, and amplify and oscillate the radiant light, said semiconductor electrode being formed of a material having such properties as to absorb the laser beams generated in said laser generating device.
