MOSCOW (Rosatom PR) — The Russian Space Systems holding (part of the Roscosmos State Corporation) has developed a project for a promising solar space power plant (SCES). It is designed to supply power to hard-to-reach – island, mountainous and northern – regions of the Earth, as well as for scheduled and emergency recharging of spacecraft.
How does a space solar station differ from those familiar to everyone on the ground? In the Earth’s atmosphere, the sun’s rays are scattered and partially lose their energy efficiency. In outer space, the efficiency of using solar energy is ten times higher. RCS scientists proposed to convert it into a laser beam and transmit it to Earth with minimal energy loss.(more…)
