A system for maintaining the depth of injected vapor in an entrochemical system is disclosed. The vapor transfer pathway terminates in the chamber containing high concentration solution underneath the surface of the solution. In one example the vapor transfer pathway is passively adjustable, using a flotation device to maintain the depth of its end. Another example uses an active, actuated system to maintain the depth of the end of the vapor transfer pathway. The energy for controlling the depth of vapor transfer pathway is minimized by passive methods and derives from the heat of mixing of the vapor and the high concentration solution.

A thermoacoustic transducer apparatus is disclosed including at least one thermal converter operable to provide power conversion between acoustic power and thermal power in a pressurized working gas contained within a working volume, a portion of which extends through the thermal converter. The thermoacoustic transducer is operable to cause a periodic flow in the working gas during operation. The apparatus also includes a reservoir volume in fluid communication with the working volume through a conduit having a working volume end in fluid communication with the working volume and a reservoir volume end in fluid communication with the reservoir volume. The conduit has a bore size and length operable to cause pressure oscillations at the working volume end to be converted to flow oscillations at the reservoir volume end such that periodic fluid flow at the reservoir volume end is at least twice as large as periodic fluid flow at the working volume end thereby facilitating a steady fluid flow along the conduit for equalization of working gas static pressures between the working volume and the reservoir volume while providing a sufficiently high acoustic impedance at the working volume end to minimize losses due to periodic flows of working gas within the conduit.

A power generation device and method using organic working fluid for circulation without pump and valve are invented, the principle is able to be called flash jet natural cycle. The flash injection tube, the magnetic sphere motion tube and the storage tank are connected to form the main loop. The finned tube and the storage tank are connected to form the cooling loop. The working fluid is heated in the flash injection tube by low-temperature heat source, and is cooled in the finned tube by air or water. The gravity and flash force jointly drive the flash jet natural cycle. The lower magnetic ball acts as a one-way valve for supplying liquid to the flash injection tube. The upper magnetic ball acts as a valve and a rotor driven by the flash force and gravity to move linearly and produce electricity.

The present application pertains to novel methods to generate power. In a representative embodiment, power is generated by warming a body of air having a temperature lower than the freezing point of liquid water by contacting the body of air with liquid water. The liquid water has a temperature greater than the freezing point of liquid water. Liquid water freezes thereby generating latent heat from freezing and thereby warming the body of air. The warmed body of air may be passed through an air turbine to generate power. Other methods and systems are described that use similar principles.

A method and mechanical system which incorporates a buoyancy engine into an Organic Rankine Cycle to create mechanical energy which may be used to generate electricity. The modified ORC consists of a closed loop containing a high molecular mass working fluid. The working fluid is vaporized in an evaporator, powers a buoyancy engine, and is recovered in a condenser. The system then utilizes a gravity feed to provide sufficient pressure at the evaporator input. The system can be implemented on a residential scale, capable of operating near ambient temperatures and pressures, and can produce carbon free electric power.

A wave energy thermal storage type seawater thermoelectric power generation device which comprises a buoy-type energy capture system, a platform system and a mooring system. A whole friction liquid heating, thermal storage and power generation device is arranged inside a platform, which improves the adaptability of the whole system to the external environment. A flywheel and liquid friction heating method is adopted to generate heat more efficiently. Inner ratchets and pawls are used to control the movement of a flywheel so that the flywheel always rotates in one direction, and when the rotating speed of the flywheel exceeds that of the inner ratchets, the external wave energy cannot be transferred to the flywheel through the movement of the inner ratchets so as to limit the upper limit of the rotating speed of the flywheel and protect the safety of the flywheel system.
