摘要:
A structure for growing plants and/or algae and for capturing solar energy including an enclosure having a roof and optionally one or more walls, a solar energy concentrator on at least part of the structure, an energy conversion device adjacent to at least one peripheral edge of the solar energy concentrator, and one or more supports or surfaces configured to enable the plants and/or algae to receive at least some of the solar energy. The solar energy concentrator absorbs or collects at least a first wavelength of light and allows at least a second wavelength of light different from the first wavelength of light to pass through (e.g., to the plants and/or algae). The solar energy concentrator comprises one or more absorbers or fluorophores selected from phycobiliproteins, fucoxanthins and luminescent molecules and materials. The energy conversion device is configured to receive and convert light emitted and/or collected by the solar energy concentrator to electrical or thermal energy.

A thermal energy storage system includes a container positioned within a surrounding body of water and comprising a container wall. The wall has an interior surface exposed to and defining an internal volume of the container and has an exterior surface opposite the interior surface and exposed to the surrounding body of water. The internal volume is substantially full of water, and the container is configured to thermally separate water within the internal volume along the interior surface from water of the surrounding body of water along the exterior surface. A thermal source in thermal communication with the water within the internal volume is configured to transfer a thermal potential to the water within the internal volume.

The present technology is directed generally to rotary displacement systems and associated methods of use and manufacture. The systems can be used to compress and/or expand compressible fluids. In some embodiments, the rotary displacement systems include a chamber housing having a pressure-modifying chamber with a first port and a second port, a first passageway in fluid communication with the chamber via the first port, and a second passageway in fluid communication with the chamber via the second port. The systems can further include a shaft positioned within the chamber housing and rotatable relative to the chamber housing about a rotational axis, and a rotor comprising no more than two lobes. The rotor can be carried by and rotatable relative to the shaft, and can be alternately operable in a first mode in which flow is provided from the first passageway to the second passageway via the chamber.

摘要:
A compressed fluid storage system includes a bi-directional compressor/expander (C/E) unit constructed to compress fluid during a first operational mode and allow expansion of fluid in a second operational mode, a fluid storage system positioned on a sea floor under a body of water, and a piping system positioned between the C/E unit and the fluid storage system and configured to pass fluid between the C/E unit and the fluid storage system.
摘要:
A method of welding / joining corrugated pipe segments, an apparatus configured to weld / join corrugated pipe segments, and a method of circulating water are disclosed. The method of welding / joining corrugated pipe segments includes holding or securing an end of each of the corrugated pipe segments with a jig, and welding the ends of the corrugated pipe segments together. The jig includes at least two rings, each configured to receive one of the ends of the corrugated pipe segments, and a brace or connector connected to each of the two rings. The apparatus includes the jig, a welding ring configured to receive the ends of the corrugated pipe segments, a resistive heating coil for heating the welding ring, and a control circuit configured to control a temperature of the resistive heating coil and maintain the temperature of the resistive heating coil once a target temperature is reached.
摘要:
An apparatus is disclosed that includes an aircraft having a cabin and an emergency air or oxygen delivery system configured to deliver air or oxygen to a plurality of persons in the cabin, a source of hyperbaric oxygen, a pressure gauge or regulator configured to measure or regulate a pressure of the hyperbaric oxygen or the aircraft, a plurality of face or head coverings configured to provide the hyperbaric oxygen to patients in need thereof, and an optional exhaust system configured to remove gas(es) from the face or head coverings without releasing the gas(es) into the cabin. Each of the face or head coverings includes a gas inlet, a gas outlet, and one or more seals adapted to contain oxygen in the face or head covering at a pressure greater than 1 atm. A related kit and a related method of treating persons with hyperbaric oxygen are also disclosed.
摘要:
Disclosed is an underwater water transfer apparatus deployable within a water body. The apparatus includes a closed receptacle suspended underwater at a first depth, the receptacle adapted to receive ambient water at the first depth therewithin as a result of either the relative movement of the receptacle with respect to the ambient water or vice versa, or both, a tube in fluid communication with the receptacle, and a heat exchanger submerged at a second depth. The heat exchanger extends from an extremity of the tube so as to alter the temperature of the incoming water from the tube, before being released at the second depth, to be closer to that of ambient water at the second depth.
