The present invention relates to an air turbine capable of, without change in its rotational velocity direction, efficiently absorbing the energy associated with a pressure difference between two spaces (A) and (B) of successively changing sign, as in the case of sea wave energy systems. The turbine comprises two sets of blades (I) and (II), each of which is similar to the blade system of a conventional turbine of radial-, mixed- or axial-flow type. The turbine also comprises a system of ducts that connect spaces (A) and (B) through any of the two blade sets (I) and (II). The turbine may be equipped with a fast-acting valve that stops the flow through one or both blade sets (I) and (II).

PCT/IN2014/000282EESAVYASA TECHNOLOGIES PVT. LTDCHAKRAVARTHY D.P.
In this method of invention, tidal waves are subjected to undergo constant collisions with hydraulic kind of systems which enhances the pressure on the rear side of the container. As the pressure exceeds due to continuous hit of tidal waves, compressed air of very higher psi is produced in carefully designed cylinders which can withstand high pressures. These cylinders are used as a fluid source to drive turbines without penstock kind of lapses found in hydral power generation methods and can continuously produce clean and green power.
