Extract B

Model space reflectors casting solar light on our planet may be developed in the near future. One sunbeam will be sufficient to illuminate one or more large districts situated in different time zones.

Researchers have developed a general design for such systems. At present an experimental project involving a reflector-satellite having a mass of 20 kg and 110 square metres of working surface is being set up at the Moscow Aviation Institute.

The aim of the experimental is above all, to check various technical approaches to the construction of the reflector of the future.

The use of reflector-satellite to prolong daylight by several hours in big cities will ensure high-quality illumination for streets, transport arteries, and construction sites. This system will also prove economically profitable.

Another possible use for such systems will be the illumination of night-work sites as well as the illumination of fields to combat night frosts.

The ecological consequences of the use of space reflectors are being studied and recommendations worked out for the rational utilization of such systems in order to benefit the environment.
