<p>The hopper water turbine is a new type of water turbine showing high performance for electric power production. It is extremely simple to be built and operated, with extremely low cost construction and installation cost, almost zero maintenance needs and negligible civil works. Basically, it is a cylinder which rotates by the friction torque of the flowing water and does not demand special blades except auxiliary ones to prevent vibrations or for torque strengthening in special conditions. This enables the water turbine to be handy and efficient even for house scale utilization. The hopper water turbine is composed by an annular stator (1) which injects the water in the interior of the hopper rotor (2) in the direction of the Coriolis phenomenon; the water swirls and drifts the hopper rotor in a rotating motion. The water outflows through the central evacuation hole (3) at the bottom and returns to the riverbed, allowing the fishes to run down the river. Additionally, the hopper water turbine is beneficial to the quality of water enriching it with oxygen.</p> |
