The controversies surrounding high oil prices and limited reserves, atmospheric pollution and nuclear safety - whether justified or not - have served to bring the energy crisis to a national awareness. It is logical, [], that attention is turning to the potentiality of tapping the unlimited resources of the sun. Many ingenious approaches have been postulated and some are technically feasible. ... Results from these preliminary studies are encouraging. They show that with proper emphasis, judicious planning and adequate funding, the projected mid-1980's technology would suffice to develop such systems that are both technically feasible and economically viable. ... The most significant conclusion to be drawn from this study is that there appear to be no insurmountable technological, design, operational, or economic barriers which should deter or delay continued investigations into the viability of satellite power systems as a strong contender for future production of electrical energy.
