Abstract: Some modular heat-transfer systems can have an array of at least one heat-transfer element being configured to transfer heat to a working fluid from an operable element. A manifold module can have a distribution manifold and a collection manifold. A decoupleable inlet coupler can be configured to fluidicly couple the distribution manifold to a respective heat-transfer element. A decoupleable outlet coupler can be configured to fluidicly couple the respective heat-transfer element to the collection manifold. An environmental coupler can be configured to receive the working fluid from the collection manifold, to transfer heat to an environmental fluid from the working fluid or to transfer heat from an environmental fluid to the working fluid, and to discharge the working fluid to the distribution manifold.

Abstract: An oceanographic sensor mooring section for use with standard oceanographic moorings comprising: mooring oceanographic equipment, such as floatation devices and sensors; and a subsurface power generation unit connected to the mooring oceanographic equipment, wherein the mooring section has connective swivels at opposing ends thereof for attachment of the mooring section to standard oceanographic moorings, mooring lines, or mooring anchors, to allow the mooring section to independently orient in the direction of current flow. The subsurface power generation unit comprises a battery and power management/tracking electronics and a rim turbine generating unit that harnesses the power of underwater currents to power any sensors and related electronics equipment.
