A floating waterwheel which has a gearing system 16 which drives a shaft 18 in a single direction regardless of the direction of the tidal flow. The waterwheel 8 is located in a flow channel between two floats or pontoons which are joined by an underwater splicing 2 which raises the water to create the maximum force on the waterwheel blades. The whole structure is enclosed in a whether proof housing 12 and is fixed to piles 7 located in the sea or riverbed by sleeves which allow the device to rise and fall with the tides. There are doors 4 to shut off the water flow through the channel between the floats, a rubber strip curtain 6 to dampen large or rough waves from impacting on the waterwheel blades and a mesh 5 is also fitted across the flow channel to prevent large fish or mammals reaching the waterwheel paddles. Preferably the gearing system comprises a ratchet system with lock or slip collars.
