Perez, Ralp LawrenceC-502HydropowerInnovations of Dams

1. Turbinesis a machine used to generate electricity from the push and pull of the river's rushing currents.is a structure on or around artificial and natural barriers (such as dams,locksandwaterfalls) to facilitate fishes natural migration.2. Fish Ladders

3. Penstock

is asluiceorgateor intake structure that controls water flow, or an enclosed pipe that delivers water tohydro turbines.4. RiverstarIt is designed to be sited in-river in interconnected arrays. RiverStar does not require a dam and reservoir; instead it harvests hydropower along a section of a river.

5. VIVACE (Vortex Induced Vibration for Aquatic Clean Energy)This converter is unlike water turbines as it does not use propellers. VIVACE uses the physical phenomenon of vortex induced vibration in which water current flows around cylinders inducing transverse motion. The energy contained in the movement of the cylinder is then converted to electricity.

Thank You!
