Abstract
A methane or methanol producing system is proposed in which 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, thereby producing methane or methanol. A laser generating device for generating laser beams by exciting radiant light in laser rods by irradiation of sunlight is installed in space. The laser beams generated are transmitted to a light-receiving facility on land or on sea, and irradiated on a hydrogen generating device having a semiconductor electrode with a wavelength suitable for absorbing by the semiconductor electrode or by converting or shifting to a suitable wavelength. Using the hydrogen, methane or methanol is produced by a methane or methanol producing unit.
