Space Solar Power Review Vol 12 Num 3&4

lighted antennas on the Moon for them and the effect of the decrease (or elimination) of interruptions in rectenna operation. In the course of the LPS development, its operation will become more and more global in terms of interaction of the rectennas located in different parts (regions) of the Earth. The operating modes of energy systems in different regions and hence in WES as a whole also become more interconnected. As was noted, large capacity of the rectennas can make it possible to produce synthetic fuel with its delivery to the systems of liquid or gaseous fuel supply. The rectennas will start to perform the function of energy centers connecting electric power and fuel-supplying specialized systems that was discussed in the previous paragraph of the report. In conclusion, it should be noted that from the energy view point the idea of the lunar power system needs additional comprehensive studies. The problem of modes (cyclicity) of energy transmission from the Moon to the Earth is of particular significance. Without satellites around the Moon and Earth the illumination intensity of rectennas on the Earth will turn out to be very rare (about 1000 hours per year). Therefore, it is necessary to study the problems on launching these satellites: their orbits, sizes, number, control of light reflectors and repeaters of the microwave beams, etc. It is quite possible that some constraints on the capacity (size) of LPS components, location of the lunar bases or terrestrial rectennas, etc. will be revealed, as is the case for the location of rectennas of SPS.
