Tidetecs concept is the most logical way to harness two-way hydropower, such as tidal, in a cost effective manner. Most tidal power plants today generate power only in one direction. Projected tidal plants with two-way production have sub-optimal production. Tidetec technology improves efficiency of the most cost effective tidal turbine technology by obtaining optimal efficiency both ways. This is achieved by integrating the turbine into a rotating turret. The turning mechanism is patented, and has received international recognition.
