Beam power with beam redirection
A beam power source transmits a signal indicating power availability, receives a request for power in response, and beams power in response to the request.
1. A method of beaming power, comprising:
broadcasting a signal indicating an ability to supply power;
receiving at a first location a request from a receiving unit at a second location in response to the broadcast signal; and
beaming power from a power beaming unit at the first location to a beam-directing unit configured to redirect the power to the receiving unit at the second location, wherein the request from the receiving unit and beamed power do not follow the same path.
2. The method of claim 1 , wherein beaming power includes locating the beam-directing unit.
3. The method of claim 1 , further comprising locating the beam-directing unit and communicating the location of the beam-directing unit to the power beaming unit.
4. The method of claim 1 , further comprising dynamically adjusting the direction of the power beam to follow a moving receiving unit.
5. The method of claim 1 , wherein beaming power to a beam-directing unit includes directing power to a plurality of beam-directing units in series.
6. The method of claim 1 , wherein beaming power includes beaming power within an enclosed space.
7. The method of claim 1 , wherein beaming power includes gradually increasing an amount of power beamed.
8. The method of claim 1 , wherein beaming power includes transmitting an electromagnetic power beam.
9. The method of claim 8 , wherein the power beam has an optical frequency.
10. The method of claim 8 , wherein the power beam has an RF frequency.
11. The method of claim 1 , wherein beaming power includes directing a laser power beam.
12. The method of claim 1 , wherein beaming power includes directing a pulsed power beam.
13. The method of claim 1 , wherein beaming power includes directing a continuous power beam.
