Hollow generator

A method of generating electricity comprising:

• providing a HOLLOW TURBINE comprising:
• at least one array of blades attached within a cylinder that is absent any center shaft and free to rotate;
• providing at least one array of magnets mounted on the outer surface of said HOLLOW TURBINE's said cylinder;
• providing at least one stator comprising at least one stationary coil of an electric conductor;
• providing a supporting structure allowing a means for said at least one array of magnets to rotate in close proximity to said at least one stationary coil of an electric conductor;
• providing 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;
• providing 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.

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;
• a cone attached to the inside surface of said intake pipe by at least one support directly before said HOLLOW TURBINE's blades, whereby said support and said cone direct incoming flows in an optimal direction to said HOLLOW TURBINE's blades and to the outermost and efficient part of said HOLLOW TURBINE's blades, whereby providing greater leverage that results in more electricity being generated.
• 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.
