摘要： A turbine apparatus (10) for deployment in a waterway, comprises a rotor support system (12), a rotor mechanism (14) and a power take-off device (16). The rotor support system (12) is operable to support and align the rotor mechanism (14) with a direction of flow of flowing water in the waterway. Deployment of the turbine apparatus (10) in flowing water generates power. The rotor support system (12) includes an elongated shaft (13), which includes a buoyancy adjusting component (17); a flexible coupling (15) at a first end; and the rotor mechanism (14) being attachable to a second free end of the elongated shaft (13). The flexible coupling (15) facilitates connection of the first end of the elongated shaft to a support structure and facilitates a substantially freely yawing connection of the axial flow turbine apparatus to a support structure located in the waterway in which the turbine apparatus is deployed. The flexible coupling (15) also controls pitching motion of the turbine apparatus (10) relative to the support structure; and in use, permits a predetermined range of yawing motion of the turbine apparatus relative to the support structure; and responds to changes in flow of the flowing water, to maintain the turbine apparatus (10) with a compliant attitude, thereby maintaining alignment of the axis of the elongated shaft and the rotor mechanism with the direction of flow. The buoyancy adjusting component (17) being operable to maintain the deployed turbine apparatus with substantially neutral buoyancy relative to the waterway in which the turbine apparatus is deployed.

摘要： Mechanical movement exerted upon or over roadways is transmitted and converted to mechanical movement conducive towards the production of electrical energy. In one disclosed system, ramped or angled push bars are disposed within a roadway, such that a front set of bars and back set of bars will not be moved simultaneously. A series of one way values may enable subterranean fluid chambers to move a pendulum flywheel or rotor in a continuous direction or in a back and forth movement.

摘要： The invention relates to the real-time determination of the forces applied by waves incident upon the moving part (2) of a wave-energy system (1). The method according to the invention is based on the construction of a model of the radiation force applied to the moving part (2) and a model of the dynamics of the wave-energy system (1). The invention uses only measurements of the kinematics of the moving part (2) and the force applied by the conversion machine (3) to the moving part (2).

摘要： The present invention generally relates to hydraulic machinery, such as hydraulic turbines. More specifically, the invention is directed to optimizing power consumption when the turbine is used in condenser mode. The present invention provides a novel hydraulic installation where the reduction of pressure in the spiral case during condenser mode operations is more efficient, limiting the power consumption if compared to state-of-the-art installations.
