NASA 2024 Space-Based Solar Power

76 • Rationale: It is generally understood that SBSP is highly cost prohibitive with today’s costs, and technically infeasible with today’s technology. Simply for comparison, we apply more of today’s costs and capabilities. • Result: Fiscal costs are increased 5.3 times for RD1 and 4.5 times for RD2. Emissions per kWh for both systems increase by a factor of 10. Table 26.
