摘要： A CO2 separation and liquefaction system such as might be used in a carbon capture and sequestration system for a fossil fuel burning power plant is disclosed. The CO2 separation and liquefaction system includes a first cooling stage to cool flue gas with liquid CO2, a compression stage coupled to the first cooling stage to compress the cooled flue gas, a second cooling stage coupled to the compression stage and the first cooling stage to cool the compressed flue gas with a CO2 melt and provide the liquid CO2 to the first cooling stage, and an expansion stage coupled to the second cooling stage to extract solid CO2 from the flue gas that melts in the second cooling stage to provide the liquid CO2.

摘要： A locomotive assembly including a legacy locomotive controller and an intercept locomotive controller and a method of controlling a locomotive are disclosed. The locomotive assembly includes a power bus, a locomotive, and an intercept locomotive controller. The locomotive includes a primary power unit coupled to the power bus and a legacy locomotive controller programmed to transmit a control command to the primary power unit. The intercept locomotive controller is electrically coupled between the locomotive controller and the primary power unit and is programmed to intercept an initial locomotive control signal transmitted from the legacy locomotive controller to the primary power unit indicating an amount of locomotive power, modify the initial locomotive control signal, and transmit the modified control signal to the primary power unit.

摘要： A compressed fluid energy storage system includes a submersible fluid containment subsystem charged with a compressed working fluid and submerged and ballasted in a body of water, with the fluid containment subsystem having a substantially flat portion closing a domed portion. The system also includes a compressor and an expander disposed to compress and expand the working fluid. The fluid containment subsystem is at least in part flexible, and includes an upper portion for storing compressed energy fluid and a lower portion for ballast material. The lower portion may be tapered proximate the flat portion to prevent it from being collapsed by ballast materials. The region between the fluid and the ballast has exchange ports to communicate water between the inside and outside of the containment subsystem. In other embodiments, an open-bottomed fluid containment system is held in position underneath a ballast system by a tensegrity structure.
