摘要： Pressure changing devices and methods of making and using the same are disclosed. One pressure changing device includes an elliptic cylinder and a piston that has an external surface with a trochoid cross-section. Another pressure changing device includes a piston and a rotating cylinder that has an internal surface with a trochoid cross-section. Another pressure changing device includes two fixed axes, one for rotation of one component and another for orbiting or oscillation of the other component. The devices and methods include stacked pressure changing devices with one or more common shafts. The pressure changing device may be easier and less expensive to manufacture and repair than prior pressure changing devices of the same or similar functionality, and can provide efficient gap sealing in a high-pressure expansion part of a compression or expansion cycle.

摘要： Systems and methods for storing and retrieving thermo-mechanical energy are disclosed. The systems and methods generally include a thermodynamic loop or cycle (e.g., a reversible transcritical, trilateral, or Rankine/vapor compression cycle) that works as a heat pump in a charging mode and as a heat engine in a discharging mode. The thermodynamic loop or cycle includes a gas pressure changing device, a liquid pressure changing device, and a working fluid. The system further includes one or more heat storage devices with solid heat storage material(s). Heat is transferred between the working fluid and the solid heat storage material(s) in the high and low pressure sides of the thermodynamic cycle, respectively.

摘要： A solar energy collector and/or concentrator, a thermal energy storage and retrieval system including the same, and methods of storing and recovering thermal energy are disclosed. The solar energy collector and/or concentrator may include an array of lenses configured to concentrate solar energy, a plurality of conduits through which a heat storage or heat transport fluid flows, and one or more heat transfer elements on each of the conduits, configured to receive the concentrated solar energy from the lenses and transfer the concentrated solar energy to the heat storage/transport fluid. The conduits are configured to move in at least first and second angular dimensions. The thermal energy storage and retrieval system may include the solar energy collector and/or concentrator, a thermodynamic cycle, and a heat storage and retrieval subsystem. Heat is transferred from the heat storage/transport fluid to the heat storage and retrieval subsystem and/or the thermodynamic cycle.

摘要： Systems and methods for storing and retrieving thermo-mechanical energy are disclosed. The systems and methods include a thermodynamic cycle (e.g., a reversible transcritical, trilateral, Brayton or Rankine/vapor compression cycle) that includes a plurality of loops and works as a heat pump in charging mode and as a heat engine in discharging mode. Each loop in the thermodynamic cycle includes pressure increasing and decreasing devices, high and low pressure heat exchanging devices, and the same or different working fluid. The system further includes one or more heat storage chains with hot and cold storage reservoirs and a heat storage fluid. At least one of the high and low pressure heat exchanging devices is a gradient heat exchanging device that exchanges heat with the heat storage chain. Also, at least one other high or low pressure heat exchanging device exchanges heat with a separate heat storage device or a heat source or sink.

摘要： An air conditioning and humidity control system, a kit, and methods of making and using the same are disclosed. The air conditioning and humidity control system includes a main conduit, distribution conduits joined to the main conduit, one or more mesh members, one or more troughs or pans below the mesh member(s), and a pump. The distribution conduits receive a fluid from the main conduit and include one or more holes to distribute the fluid. The mesh member(s) receive the fluid from the distribution conduits, and allow the fluid to flow along its length. The trough(s) or pan(s) collect the fluid from the mesh member(s). The pump receives the fluid from the trough(s) or pan(s) and pumps the fluid to/through the main conduit. The air conditioning and humidity control system effectively controls the temperature and humidity of an enclosed room or building, improves air quality, is simple and inexpensive to make and operate, and avoids use of greenhouse gases.

摘要： A thermal energy storage and retrieval device includes at least one working fluid and a plurality of thermodynamic circuits. Each thermodynamic circuit has a first process exchanging heat with a first material in a first temperature range common for all of the thermodynamic circuits. Each thermodynamic circuit also has a second process exchanging heat with a second material in a second temperature range. The second material comprises a heat storage material or a working fluid in another circuit or another device. Each thermodynamic circuit includes a gas pressure changing device and a liquid pressure changing device.

摘要： Systems and methods for transferring and optionally storing and/or retrieving thermal energy are disclosed. The systems and methods generally include a heat engine and a heat pump, the heat engine including first isothermal and gradient heat exchange mechanisms, and the heat pump including second isothermal and gradient heat exchange mechanisms. The heat engine and the heat pump exchange heat with each other countercurrent across the first and second gradient heat exchange mechanisms, the first isothermal heat exchange mechanism transfers heat to an external heat sink, and the second isothermal heat exchange mechanism receives heat from an external heat source.

摘要： A boat having a mainsail and a conventional rudder. The mainsail is supported by a mast and a pivotally mounted boom. A blade is pivotally mounted toward the free end of the boom about an axis that is substantially parallel to the mast. The blade acts as an auxiliary rudder for steering the boom and setting the angle of the sail. Though the boom pivots, the blade may be held parallel to a pre-set direction, so that the leeway component of the force of the wind on the sail is held substantially constant.
