Abstract: A method and system are disclosed for cooling a laser, such as a high average power (HAP) solid state laser (SSL). A coolant that has been heated from previous use can be conditioned by transferring heat from the coolant to a phase change medium. The conditioned coolant can then be re-used to cool the laser. In this manner, a low cost, lightweight, compact cooling system that generates comparatively quiescent flow at comparatively high flow rates can be provided.

Abstract: An internal combustion engine system for automotive vehicle wherein liquid water is produced by cooling a portion of exhaust gases at elevated pressure to induce condensation. The use of elevated pressure allows condensation to occur at a higher dew point which is easier to realize with cooling by ambient air. Liquid water condensate is collected and provided to an electrolytic cell for electrolysis into gaseous hydrogen and oxygen. Hydrogen gas generated by the cell is used by the internal combustion engine to reduce internal combustion engine wear and to reduce exhaust pollutants especially during start-up. Alternate uses of the liquid water include a replenishment of engine coolant and window washing fluid.

Abstract: A solid state laser module for amplification of laser radiation. The module includes a laser gain medium having a pair of generally parallel surfaces that form a disc-like shape, that receive and transmit laser radiation. At least one perimetral optical medium is disposed adjacent a peripheral edge of the laser gain medium and in optical communication therewith. A source of optical pump radiation directs optical pump radiation into the perimetral optical medium generally normal to the parallel surfaces and the perimetral optical medium transports the optical pump radiation into the laser gain medium to pump the laser gain medium to a laser transition level. Alternative embodiments include arrangements for directing cooling fluids between adjacently disposed laser gain media.

Abstract: An autonomous water source (AWS) for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation (ADC) cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth. The invention provides a sustainable source of irrigation water for agriculture and forestry, including areas where no water resources exist or are not economically viable. It can be tailored in size, and therefore, output capacity, reflecting the desired water requirements of a particular application, and can be used to replace most agricultural situations now reliant on surface water drip feed systems. The device is simple, rugged, invulnerable to rain, snow, and freezing conditions, and can be designed to last for many years without service as there are few moving parts and power required for operation is provided by sunlight.

Abstract: The invention is for an apparatus and method for a refrigerator and a heat pump based on the magnetocaloric effect (MCE) offering a simpler, lighter, robust, more compact, environmentally compatible, and energy efficient alternative to traditional vapor-compression devices. The subject magnetocaloric apparatus alternately exposes portions of an MCE material to strong and weak magnetic field while coordinating the heat flow between the exposed portions by heat bridges to move the heat up the thermal gradient. The invention may be practiced with multiple MCE material portions or segments to attain large differences in temperature. Key applications include thermal management of electronics, as well as industrial and home refrigeration, heating, and air conditioning. The invention offers a simpler, lighter, compact, and robust apparatus compared to magnetocaloric devices of prior art. Furthermore, the invention may be run in reverse as a thermodynamic engine, receiving low-level heat and producing mechanical energy.

Abstract: A laser system including two laser amplifier modules, each comprising a solid-state laser gain material (LGM) disk, and a multi-pass optical assembly comprising a plurality of relay mirrors. The relay mirrors are grouped in two relay mirror groups. Individual relay mirrors are arranged to pass a laser beam from the first LGM disk to the second LGM disk and back to the first LGM disk, and so on. The laser beam is amplified with each pass through the LGM disk. The relay mirrors may be arranged to repeat the process of passing the laser beam to and from the two LGM disks arbitrary number of times until the desired laser beam amplification is attained. At that point, the laser beam may either released from the laser system, reflected back causing it to retrace its path through the system. This configuration increases the effective gain and improves laser power extraction.
