Abstract

PURPOSE:To provide the subject apparatus capable of culturing algae by microwave transmitted from a solar light power plant of a space station by providing a wave- receiver to converge the incident electric wave of giga-hertz order, etc., to form a converged electric wave and providing a primary light source emitting light by receiving the converged electric wave. CONSTITUTION:Electric energy generated by a solar power plant of a space station is transmitted to the earth by microwave and light is directly generated from a light source by the microwave. The above apparatus is provided with a wave-receiver 3 such as a parabola antenna to converge the incident electric wave 1 of giga-hertz order, etc., to a convergent point 2 to form a converged electric wave. A light-emitting tube 6 obtained by coating a fluorescent material to the inner surface of a sealed tube containing an electrically conductive material such as mercury vapor is used as a primary light source 5 generating light by the converged electric wave and positioning at least a part 4 on the convergent point 2. A part 7 of the primary light source 5 or a secondary light source 9 receiving light from the primary light source 5 through a light guide 8 is immersed in a medium 11 for the culture of algae 10, etc., and the algae 10 are cultured and proliferated by the light radiated into the medium 11 from a part 7 of the primary light source 5 or from the secondary light source 9.
