A power generation system anchored to a hydraulic arm, capable of pivoting up or down to optimize power generation based upon the present conditions of the flowing body of water. The turbines are augmented by diffusers to improve fluid flow and power generation. The overall design is easily built, installed, and maintained, providing easy power to homes without a need to connect to a public grid, and safety measures are affixed to prevent undesired items from entering the turbine propellers.
