NOVELTY - Methane/methanol producing system has a laser generating device installed in space around the earth to generate laser beams by sunlight, a hydrogen generating unit having a semiconductor electrode irradiated with the laser beams to generate hydrogen, and a methanol producing unit. The laser generating device includes several laser rods containing a laser activating substance.    USE - The system is used for methane/methanol production.    ADVANTAGE - Laser beams are generated in space by excitation of sunlight, transmitted onto land or sea without loss to obtain optical energy with high efficiency, and irradiated on a hydrogen producing device to produce industrially inexpensive hydrogen with high efficiency, thus producing methane or methanol.    DETAILED DESCRIPTION - Methane/methanol producing system comprises a laser generating device (20) 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 (10) comprising a semiconductor electrode for receiving the laser beams and generating hydrogen, and a methanol producing unit (40) for producing methane or methanol by synthesizing the hydrogen generated with carbon monoxide or carbon dioxide under high pressure.    The semiconductor electrode is irradiated with the laser beams to generate hydrogen by decomposition of water. The laser generating device includes several laser rods containing a laser activating substance and adapted to condense and irradiate sunlight on the laser rods to generate radiant light from the laser rod by the action of the laser activating substance, and amplify and oscillate the radiant light. The semiconductor electrode is formed of a material having such properties as to absorb the laser beams generated in the laser generating device.
