The nominal estimates of tables VI-5 to VI-8 were used to derive the nominal cost of transportation for implementing a nominal network of SPS units and to develop the overall program model presented in section VII. The minimum, nominal, and maximum estimates were used with SPS1s of minimum, nominal, and maximum weights to develop the range of estimates of the "cost of electricity," presented in section XI. The nominal estimates of tables VI-5 to VI-8 were also used to derive the nominal cost of transportation for implementing nominal weight SPS's with different configurations and construction locations. These results are presented in table VI-9 and indicate the expected reduced costs of constructing the system in LEO and utilizing energy from the system to provide power for orbital transfer. The calculations also indicate the small percentage (<5 percent) of costs involved in personnel transfer. It is also apparent that the cost of cargo transport to LEO dominates the space transportation cost elements.
