Abstract: PROBLEM TO BE SOLVED: To solve environmental problems caused by the conventional power generation method by use of natural solar energy, and to provide a system to supply solar energy from a remote place to a place of consumption efficiently. SOLUTION: In this energy supply network which uses solar light pumped laser, means of generating a solar light pumped laser which can absorb energy of a wide band spectrum and oscillate it as laser is installed at a location easy to secure space such as in outer space. The laser enables to transmit energy to a remote distance efficiently as highly directional laser by reflecting, controlling and transmitting to the destination at a facility outside the earth such as satellites stationed at places in the network. In the area where laser absorption loss is large due to the atmosphere, the laser is irradiated to an airship floating in the stratosphere, converted to microwave on the airship, and transmitted to the power network on the ground.

Abstract: PURPOSE:To provide a cosmos synthetic energy conversion system for the shallow and deep cosmos spheres which is small-sized and lightweight and secures the high energy conversion efficiency. CONSTITUTION:The solar energy is utilized effectively and efficiently by arranging the light/electricity converters 3, 9, and 16 on the obverse surfaces and arranging the heat/electricity converters 4, 10 and 17 on the reverse surfaces of the concaved surface reflective mirrors 2, 8, and 15 for converging the solar beams to the heat collectors 5, 11, and 18 by the first-fourth power generation systems 1, 7, and 14, and the solar energy which is strong in the shallow cosmos is stored in the form of electricity and heat, and used as the energy source in the shadow part of the sun and in the deep cosmos. Since the hydrogen and oxygen of thrust generators 29 and 30 are generated through the electrolysis of water, the device can be made small-sized and lightweight, and the thrust is increased by heating hydrogen, and the efficiency of the heating of hydrogen and the heating of water in the electrolysis is increased through the direct heating by the heat of the heat collectors 6 and 19. A radioactive ray source 32 using the self-supplied energy source in the deep cosmos is mounted, and the radioactive rays radiated from the radioactive ray source 32 is converted to the thermal energy and electricity by the nuclear heat converters 33 and 35 and a thermal converter 37.

Abstract: PROBLEM TO BE SOLVED: To provide a system where power as energy required for controlling a laser optical system is generated within the optical system, without having to depend on an external supply by making effective use of laser energy leaking from the laser optical system, which conventionally has merely been a loss. SOLUTION: In the power generation system using energy leaking from the laser optical system, a translucent-type reflector is deliberately used, and solar cells are placed behind the reflector. Thus, the energy of laser light, passing through, is used to generate power. The amount of electricity generated is adjusted, by varying the permeability of the reflector to vary the amount of energy which reaches the solar cells. At this time, a photoelectric element, corresponding to the wavelength of the laser is selected and used. Thus, energy can be extracted at high conversion efficiency. Further, thermoelectric elements are caused to generate electricity, utilizing heat emitted from the laser optical system.
