Abstract: A system and method are provided for storing and recovering electricity generated from conventional/renewable energy sources. A thermal energy storage vessel contains thermal storage fluid (“TSF”) comprising a eutectic ternary nitrate molten salt, induction heating elements, turbine pumps, a heat exchanger, and various data acquisition sensors like thermocouples and thermistors. The immersion heating elements receive the electricity generated from conventional and/or renewable energy source to heat the eutectic ternary nitrate molten salt to the desired temperature. Coiled tubing is deployed within the thermal containment vessel to be distribution systems for the power cycle working gas and heat exchange for the power cycle working gas. The power cycle working gas is delivered under pressure to a steam turbine. The turbine converts the energy into mechanical shaft work to drive an electricity generator to produce electricity.

The accelerator may be manufactured using an additive manufacturing method. The accelerator outlet may be disposed immediately upstream of a first turbine rotor blade stage of a gas turbine engine to direct the cooling fluid thereto.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for a lighting controller for sea lice detection. In some implementations, fish are contained within an elliptical tank filled with water. An imaging station located on the elliptical tank is used to capture an image of a fish from which image analysis can be performed to detect sea lice or other skin features, including lesions, on the fish. Pairs of imaging assemblies coordinate pulsing light of at least a first and a second color and capturing images of the fish while the fish is illuminated by at least the first and the second color. By using the captured images with different color light, computers can detect features on the body of a fish including sea lice, skin lesions, shortened operculum or other physical deformities and skin features. Detection results can aid in mitigation techniques or be stored for analytics.
