摘要： A method of recovery of optical fiber expended during a parabolic launch trajectory of a spacecraft is disclosed. An optical fiber adapted for transmission of high optical energy sufficient to launch the spacecraft is connected at one end to the spacecraft and is released during launching of the spacecraft. The optical fiber expended from the spacecraft is then engaged by a drum spooler following launch of the spacecraft and the fiber has been fully spooled out by the spacecraft. The optical fiber is then reeled in prior to the fiber contacting the Earth. The recovered optical fiber is then collected for processing, cleaning and rewinding for future use of subsequent series of launches for as many times as possible.

摘要： A laser-powered ice-penetrating communications payload delivery vehicle for sub-ice submarine missions enables under-ice operations to exchange information with terrestrial facilities or satellite networks with communications methods otherwise blocked by an ice cap. The vehicle comprises an electronics bay, a payload bay, optics bay, and a melt optic with laser. The system and method of establishing communication where the vehicle, tethered to a sub-ice vessel, is released. The vehicle ascends to the bottom of an ice sheet and uses a laser to melt the ice, forming a borehole through which the vehicle continues to ascend. When buoyancy no longer advances the vehicle beyond sea level, the vehicle continues to melt a conical opening through the ice until unobstructed atmosphere is reached and bi-directional communication is established. Where the melting capacity cannot reach ice to continue melting, the vehicle mechanically advances itself toward the surface to establish high bandwidth, bi-directional communication.

摘要： A direct high voltage flow-through water heater system transmits high voltage power to a remote ice penetrating robot, converts the power to heat in a very small space, and then uses the heat to melt the ice, providing a path ahead of the robot allowing penetration deeper into a remote ice-covered location, such ice of substantial (e.g., kilometers) thickness, such as, for example, glacial ice caps. High voltage, low current, AC power is passed through a moving conducting fluid, inducing resistive heating in the fluid with 100% efficiency. The exiting fluid is stripped of common mode voltage before exiting. Energy transfer from the electrical source to the fluid is instantaneous and occurs at 100% efficiency. In an alternative embodiment, the fluid heater system operates at standard residential/industrial mains voltages and runs from 220 VAC as other applications of the present invention include the traditional water heater industry as well.

摘要： A power conversion module for use with optical energy transfer and conversion system has a hemi-spherically configured housing, an array of photovoltaic chips mounted on the interior thereof, and inlet and outlet ports connected thereto. An end plate connected to the housing defines a cavity. An actively cooled high-power connector has one end connected to a fiber optic cable and the opposite end traversing the end plate and extending within the cavity. Beam forming optics within the cavity are in optical communication with the connector to disburse received optical energy in a hemispherical emission pattern of uniform flux toward an array of photovoltaic chips mounted in complementary configuration to the housing within the cavity, each chip spaced equidistantly from the beam forming optics. A heat sink within the housing has a plurality of fluid channels therethrough through which a work fluid removes heat via the outlet port. In alternative embodiments, the power conversion module includes a housing having a spherical configuration and a plurality of power conversion modules.

摘要： An optical energy transfer and conversion system comprising a fiber spooler and an electrical power extraction subsystem connected to the spooler with an optical waveguide. Optical energy is generated at and transferred from a base station through fiber wrapped around the spooler, and ultimately to the power extraction system at a remote mobility platform for conversion to another form of energy. The fiber spooler may reside on the remote mobility platform which may be a vehicle, or apparatus that is either self-propelled or is carried by a secondary mobility platform either on land, under the sea, in the air or in space.
