Power collection and transmission system and method
First Claim
1. A solar power collection and transmission system comprising:
- a plurality of solar power collecting assemblies for collecting solar radiation incident on said solar power collecting assemblies;
means defining a microwave radiating aperture of predetermined area comprising an array of separate, spaced apart microwave sources for emitting a plurality of separate microwave beams, and structurally separate microwave redirector means for redirecting the emitted microwave beams in a predetermined beam direction and expanding the effective microwave emitting area to substantially fill the microwave radiating aperture;
conversion means associated with each solar power collecting assembly for converting said collected solar power into a power form suitable for connection to said microwave sources;
each solar power collecting assembly and associated conversion means being connected to at least a respective one of said sources;
phase control means associated with said microwave sources for controlling the relative phase of microwave beams emitted from said sources to form a composite, shaped microwave beam directed from said microwave redirector means, the composite beam having separate radiating near field and far field regions; and
at least one microwave receiver assembly positioned in the radiating near field region of said microwave beam.

Abstract
A system for transmitting microwaves to one or more receiver assemblies comprises an array of separate microwave transmitting assemblies for emitting a plurality of microwave beams, the array being arranged to apparently fill a radiating aperture of predetermined shape and size when viewed from the direction of a receiver assembly, and a phase controlling assembly associated with the microwave transmitting assemblies for controlling the relative phase of the emitted beams to form at least one composite shaped microwave beam directed to at least one receiver assembly. The receiver assembly is located in the near field of the microwave beam. The transmitting assemblies are each associated with separate power sources comprising solar power collecting assemblies. In one arrangement the transmitting system is on the moon and the or each receiver assembly is on Earth.

8. A method of transmitting a microwave beam to at least one receiver located in the radiating near field region of the microwave beam, comprising:
-
collecting solar radiation incident on a plurality of solar power collecting assemblies; forming a microwave radiating aperture of predetermined area by arranging an array of separate, spaced apart microwave sources to form a series of separate microwave beams directed at a series of separate microwave reflectors for reflecting and redirecting the separate beams into a common beam direction and expanding the effective microwave emitting area to substantially fill the microwave radiating aperture, the microwave reflectors being positioned so as to apparently define a radiating aperture of said predetermined area when viewed from the common beam direction; connecting the microwave sources to conversion means associated with the solar power collecting assemblies for converting the collected power into a power form suitable for connection to said microwave sources, each solar power collecting assembly and associated conversion means being connected to at least a respective one of said microwave sources; controlling the phase of the microwave beams emitted from the microwave sources so as to combine the separate beams into at least one composite, shaped microwave beam directed from said microwave reflectors, the composite beam having a separate radiating near field and far field region; and receiving the microwave beam at at least one microwave receiver assembly located in the radiating near field region of the microwave beam. - View Dependent Claims (9)
