An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

A rotary device (e.g., a rotary jet), power generation system, and methods of manufacturing and using the same are disclosed. The rotary jet includes a central axle or shaft, an inlet configured to receive at least one fluid, and a plurality of radial arms in fluid communication with the inlet, configured to rotate around the central axle or shaft. Each radial arm has a nozzle at a distal end thereof and an arc between the inlet and the nozzle. The radial arms extend radially from the central axle or shaft at least in part, and are configured to rotate when the fluid enters the inlet and passes through the radial arms, or when a rotational force is applied to the central axle or shaft. Each nozzle may have an opening facing away from a direction of rotation of the radial arms or facing in a direction parallel with the central axle or shaft.

An energy storage system (TES) converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the TES provides higher-temperature heat through non-combustible fluid to an alumina calcination system used to remove impurities or volatile substances and/or to incur thermal decomposition to a desired product.

Water rescue of an individual whether they be a man overboard (MOB) from a boat or someone close to shore requiring a water rescue by shore lifeguards, can easily become a dangerous and life-threatening situation within a few seconds.

The current invention offers a Compact Powered Rescue Apparatus (CPRA), a lightweight and compact powered watercraft that can be deployed from a moving boat in just seconds thanks to an innovative CO.sub.2 inflation system. CPRA can be stowed on-board a vessel and automatically inflated in just seconds much like the compulsory life-raft or pre-inflated and ready to deploy immediately from shoreline lifeguard stations.

CPRA is a powered watercraft based on U.S. Pat. No. 5,643,029 Motorized Surf Boots (Powered Waterskis), a recreational watercraft. However, in this case the craft is made inflatable, configured with a portable stretcher for water search-and-rescue operations, and driven by battery powered electric marine thrusters.
