Patent ID: 7843099

Claim:
An all-in-one turbine and electric generator comprising: a HOLLOW TURBINE comprising: at least one array of blades attached within a cylinder that is absent any center shaft and free to rotate; at least one array of magnets mounted on the outer surface of said HOLLOW TURBINE's said cylinder; at least one stator comprising at least one stationary coil of an electric conductor; a supporting structure; an intake pipe whose outer diameter is less than the inner diameter of said cylinder, wherein said intake pipe is mounted inside said cylinder, whereby preventing incoming flow from making contact with the turbine until said flow comes into direct contact with said HOLLOW TURBINE's said at least one array of blades; an exhaust pipe whose outer diameter is less than the inner diameter of said cylinder, wherein said exhaust pipe is mounted inside said cylinder, behind the turbine blades, whereby preventing the exiting flow from making contact with said cylinder; whereby kinetic energy is captured and transformed into electricity efficiently in a compact fashion that allows fish and debris to safely pass over said at least one array of blades and through the turbine's vacant axis of rotation; whereby the weight and drag of said flow does not degrade the efficiency of said HOLLOW TURBINE.
