Transmission and reception of energy from laser space solar power plants

The atmospheric transparencies windows indicating the need to shift the wavelength of the laser to 1.4 microns, which will require significant material science efforts, are presented. It is indicated that even in the worst weather conditions today can be selected laser wavelength, providing up to 20% absorption. In the situation with the difficulties of balloon reception, mainly because of the terrorist threat, you should probably accept such losses and abandon the use of balloons. Data from the history of development of aerostat balloons are given, their technological and operational difficulties are pointed out. It is noted that the angle reflector on the ground photo module can provide accurate guidance of the laser beam. At ground reception of laser radiation by solar panels their efficiency is 15-30% higher than to the solar spectrum. The environmental impact of laser systems is much less than the microwave (microwave) analogues. The features of network inverters and ground infrastructure of laser space solar power plants are described. © 2020, Univelt Inc. All rights reserved.
