A generating apparatus for generating electrical power from a water flow to electrical energy includes a pump; pipes; tidal stream generation devices; and drains. The pump is connected to and in fluid communication with the pipes. The pump may pump seawater to the pipes and sweater may further flow to the tidal stream generation devices so that the tidal stream generation devices may generate electrical power from a seawater flow to electrical energy. The tidal stream generation device includes a turbine driven by seawater, a shaft co-rotated with the turbine, a reduction gearbox operatively connected to the shaft, an output shaft extending out of the reduction gearbox, and an alternator driven by the output shaft to convert mechanical energy to electrical energy in the form of AC, and an electrical grid electrically connected to the alternator. The drain is connected to the pipe for flowing seawater to the sea.

The present invention relates to a tidal power generating system for blocking paths through which seawater passes at points where there is a difference between the ebb and flow of the tide, so as to create a strong water current and use the water current to generate electricity.

A hydraulic turbine includes a rotor with a runner, which is concentrically surrounded by a stator, whereby the runner comprises a plurality of runner blades arranged and distributed in a ring around a rotor axis, and each runner blade extends between a runner crown and a runner band; whereby the stator comprises a plurality of guide vanes arranged and distributed in a ring around the rotor axis, and each guide vane extends between an upper stator ring and a lower stator ring; and whereby a predetermined clearance is provided at least between the runner band and the lower stator ring. A substantial reduction of pressure pulsations in the vane-less gap between said runner blades of said runner is achieved by substantially increasing said predetermined clearance.

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.

The present invention provides a power generation system installed in a river, a channel, a coast, a windy place, or the like to thereby enable power generation using a natural energy such as hydraulic power, wind power, or the like.

The power generation system 1 of the present invention comprises a turbine 2, a cam wheel device 6, a power generator 7, and an arm mechanism 8. The turbine 2 comprises a rotating shaft 11 that rotates by the application of hydraulic power or wind power. In the cam wheel device 6, the torque of the rotating shaft 11 is transmitted to the cam wheel 18, thereby rotating the cam wheel 18. The power generator 7 can generate power by converting the rotational energy of the rotating shaft 28, which is generated as the rotating shaft 28 rotates with the rotation of the drive wheel 29, to electric energy. When the cams 21 come in contact with the arm mechanism 8 with the rotation of the cam wheel 18, a rotary motion is generated in the arm mechanism 8. This rotary motion brings the arm mechanism 8 in contact with the drive wheel 29, thereby rotating the drive wheel 29.
