The first establishes the economics to justify development of energy from space and wireless power transmission while the latter two demonstrate that there are structural mechanisms that can be built upon to facilitate implementation. Figure 10 Solar Power Satellites and the Resources of "Greater Earth" The second part of this section consist of a review of some of the limitations of renewable energy systems. Then the basis for an inexhaustible system is established and the concluding subsection integrates the results. The subsections are: • North African Solar Hydrogen Farms • Solar Fuels • Inexhaustible Systems Level Playing Field for Evaluation of Energy Systems We need to develop a level playing field for evaluating energy options. This requires that energy supplies be evaluated on an equal basis. This means that if cost is to be the final or main arbitrator then all costs should be accounted for. This includes upstream costs such as the impact of strip mining coal and black lung disease in coal miners as well as downstream costs such as waste disposal of fly ash and spent fuel and the decommissioning of facilities. Figure 11 diagrams the environmental impacts of different generation technologies. Figure 12 is a similar diagram for electrical energy derived from Solar Power Satellites. Not included in that diagram is the effects of
