Abstract
A method and system for solar powered charging of an electronic device is provided. Solar concentrators direct solar energy onto photovoltaic cells on an orbiting space station or a satellite in a geostationary orbit. The photovoltaic cells convert the solar energy to direct current (DC) electrical power. Energy generators convert the DC electrical power to generate energy waves, for example, microwaves. A space transmitter relays the energy waves to one or more earth stations. The electronic device transmits a locator beam indicating its current location. On receiving the locator beam, an earth station transmits the energy waves to the electronic device. A rectenna, in electronic communication with the electronic device, converts the energy waves to DC electrical power and directs the DC electrical power to a charger in electric communication with the electronic device. The charger receives the energy waves or the DC electrical power and charges the electronic device.
