Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
138 words
A water turbine comprising: (a) an impeller assembly having multiple blades mounted perpendicularly on a rotatable axle, (b) a housing assembly having a frame fixed about and attached to said impeller assembly, said wall having an opening for receiving a water stream, said opening comprising multiple flow channels formed by a series of curved plates wherein each channel has a water entrance section wider than a water exit section, each water exit section located at a different area about said blades, said opening extending outward and angularly to said water stream, (c) a water vortex discharge assembly having a discharge channel to receive said water from below said blades and delivering said water to a venturi eductor having a restricted passageway, and (d) a second turbine located within said discharge channel at a position within said restricted passageway.
