Energy Generation from Water Waves and Storage of Energy

Номер: US20190003448A1
Принадлежит:

Disclosed is a system and method for generating and storing energy from water waves. Oscillatory motions of a floating base are transmitted to adjustable weights enclosed in a container suspended from a frame that is rigidly installed inside the floating base. The container is operably coupled to a sheave, via a crank. The movement of the adjustable weights in the container results in the movement of a sheave that is operably coupled to an output shaft that is in turn coupled to an electric generator via a network of gears. The generator supplies power to an electrolyzer producing hydrogen and oxygen from water. The hydrogen and oxygen are compressed into gas or liquid and stored in containers on-board the floating base, until they are off-loaded at a facility. 11132353152404243343337363534521435451339384144. An apparatus for converting water wave energy into usable electrical energy , said apparatus comprising: a floating base that is floating on a surface of a large body of water having water waves , said floating base moving upward and downward in response to said water waves; said floating base includes an upper surface that is configured and adapted to house more than one large unit of items and a lower surface that is configured and adapted to float on said large body of water without capsizing; a rigid stable frame that is substantially vertically disposed and firmly affixed on to said upper surface of said floating base; a sheave that is substantially vertically operably coupled to a supporting horizontal member of said rigid stable frame , said sheave being configured to vertically rotate around an axis of rotation on a bearing ; adjustable weights , suspended from said horizontal supporting member of said rigid stable frame , said adjustable weights being enclosed in a container , said container being operably coupled to said horizontal supporting member of said rigid stable frame by a least one suspension spring capable of contracting and expanding ...

Mixed-flow cooling to maintain cooling requirements

Номер: US10777966B1
Принадлежит: Lockheed Martin Corp

An apparatus that includes a plurality of heat sources; a heat sink coupled to the plurality of heat sources; a heat-exchange-fluid flow path for heat-exchange fluid to flow through such that heat is removed from the heat sink, wherein the flow path includes: a heat-exchange-fluid inlet, a first branch that includes a plurality of segments including a first and second segment, wherein each of the plurality of segments includes an upstream end and a downstream end, wherein a first portion of the heat-exchange fluid flows through the first segment in a first direction and the first portion of the heat-exchange fluid flows through the second segment in a second direction, opposite the first direction, and a second branch, wherein a second portion of the heat-exchange fluid flows through the second branch such that the second portion of the heat-exchange fluid mixes with the downstream end of the second segment.
