What are Solar Power Satellites?

A solar power generation system that has been conceived since the early 1970s. Solar collectors in satellite orbits transmit the energy collected from sunlight to the earth in microwave or laser light, which is converted into electricity after it is received on the surface of the earth. The advantage is that there is no atmospheric obstruction between the sun and the solar collector, so it is more efficient and not affected by the diurnal cycle. Is a renewable energy source. The cost is still very high, with inconsistent economic benefits, and it may be built after further technological development or further rise in energy prices.
