the scaling advantages enjoyed by the millimeter wave power transmission over longer wavelength RF. The 50 MWe rating of the baseline GEO/mm concept is also compatible with the current trend in the U.S. of new units coming on-line in 50-100 MWe increments. 3.8. Planetary Power Web The Planetary Power Web is a space solar power concept which assumes a mature network of space solar assets in the form of space based systems which convert sunlight into electricity and ground based receivers designed to convert radio-frequency energy into electricity for baseload power or for other uses such as synthesis of chemical fuels. The initial concept was for a dedicated array of 4 or more very large space structures in GEO which could generate solar power in their own right as well as relay power from other system elements. The architectural context of the Planetary Power Web is illustrated below in Figure 3-13. Figure 3-13 The Planetary Power Web Concept Architectural Context
