3. place solar power plants in orbit above Earth where they would convert sunlight to electricity and beam the power to ground-based receiving stations. The ground-based stations would be connected to today's regular electrical power lines

6.  The satellites would be placed in so-called "geostationary“  The receiving antenna is called a "rectenna"  only moving part on the satellite is the transmitter antenna which slowly tracks the ground-based rectenna  The transmitter on the SPS is an array of waveguides convert the electricity into a radio or microwave beam  The ground-based rectenna consists of an array of antennas convert the energy into regular AC electricity

7. MODELS OF TX & RX

9. C OMPARISON WITH TODAY ENERGY SOURCES world gets about 95% of its energy from coal, oil and natural gas & 5% from nuclear power The mass of the rectenna would be a little bit less that a coal fired power plant with the same output
