Abstract
Methods and apparatus for beaming power from one location to another are provided. Energy is used to power one or more lasers to provide a coherent, wide-aperture beam, which is directed to the receiving platform. Photovoltaic cells on the receiving platform convert energy of the laser beam into electrical energy. Receiving platforms are provided that take advantage of the higher energy density in the laser beam.
Claims20
An apparatus comprising:
- a remote platform including a photovoltaic cell;
- and
- an optical power emitter including a plurality of lasers to provide a plurality of laser beams having photonic energy, the plurality of beams being coherent with respect to each other;
- wherein the optical power emitter directs the plurality of beams at the platform;
- and
- wherein the platform is at an altitude with respect to the optical power emitter.
3 more elements
A method for a degraded photovoltaic cell comprising:
- overly illuminating the degraded photovoltaic cell with a laser beam to supply the photovoltaic cell with the avenge photonic energy of more than one sun equivalent;
- wherein the over-illumination increases the electrical energy production capacity for the degraded photovoltaic cell to approximately the same level as the electrical energy production capacity for a good photovoltaic cell illuminated with the average photonic energy of one sun equivalent.
