This document describes a proposed solar power satellite concept. It involves a large solar collector in space that would collect solar energy and transmit it to Earth via microwave beams to a receiving antenna. The receiving antenna would be a large disc 3 to 6 km in diameter that would convert the microwave energy directly into electricity without needing wires. The concept aims to transmit power from space at 5.8 GHz and 2.8 GW to provide a renewable source of energy to meet growing demand.

4. A HUGE SOLAR COLLECT0R MADE UP OF SOLAR
CELLS
A MICRO WAVE ANTENNA ON THE SATELLITE
AIMED AT EARTH
AN ANTENNA OCCUPYING A LARGE
AREA ON THE EARTH TO COLLECT
THE POWER

5. EARTH POINTING DISC OF SIZE
3 TO 6 KM DIA .THE DISC IS
CONTINUALLY SUN FACING
THE CONCEPT IS ASSUMED TO
TRANSMIT 5.8 GHZ FROM AN
OPERATIONAL GEO LOCATION AT
A TRANSMITTED POWER LEVEL OF
2.8 GW

6. TO TRANSMITT THE POWER THROUGH OUTER SPACE
OR THROUGH THE ATMOSPHERE WITHOUT NEED OF
WIRES
GENRATED BY USING
CAVITY MAGNETRONS

7. USED TO DIRECTLY CONVERT
MICROWAVE ENERGY INTO DC
ELECTRICITY
CONSTRUCTED FROM A
SCHOTTKY DIODE
PLACED BETWEEN
ANTENNA DIPOLES

8. CURRENT RATES ON THE SPACE SHUTTLE RUN
BETWEEN $3000 & $5000/POUND
THOUSANDS OF ROCKET LAUNCHES
COULD VERY WELL REDUCE THE COSTS
BY 10 TO 20 TIMES
THE HIGH CONSTRUCTION COST OF SPS
BECOME FAVOURABLE DUE TO THERE LOW
COST DELIVERY OF POWER

9. RENEWABLE ENERGY IS A COMPELLING APPROACH
BOTH PHILOSOPHICALLY AND IN ENGINEERING
TERMS
SPS APPEAR TO POSSESS MANY SIGNIFICANT
ENVIRONMENTAL ADVANTAGES WHEN
COMPARED TO ALTERNATIVE APPROACHES TO
MEETING THE INCREASED ENERGY DEMAND
