Hollow turbine

A method of transforming kinetic energy into rotational energy comprising:

• providing a cylindrical shell having an inner and an outer surface, and a hole at each of the opposing ends of said cylindrical shell;
• providing at least one array of blades attached to said inner surface of said cylindrical shell;
• providing an intake pipe whose outer diameter is less than the inner diameter of said cylindrical shell, wherein said intake pipe is mounted inside said cylindrical shell and prevents the incoming flow from making contact with the turbine until said flow comes into direct contact with said at least one array of blades;
• providing an exhaust pipe whose outer diameter is less than the inner diameter of said cylindrical shell, wherein said exhaust pipe is mounted inside said cylindrical shell, adjacent to, and on the opposite side of said blades from said intake pipe, and prevents the exiting flow from making contact with said cylindrical shell;
• providing at least one means for significantly aligning the base of said blades with the inner surfaces of said intake and said exhaust pipes;
• providing a supporting structure;
• providing at least one means to allow said cylindrical shell to rotate freely in said supporting structure;
• providing at least one rotational energy connecting element;
• whereby preventing flow from adding weight, drag, and vibration to said cylindrical shell;
• whereby providing a means of efficiently supplying rotational energy.

A pump comprising:

• a cylindrical shell having an inner and an outer surface, and a hole at each of the opposing ends of said cylindrical shell;
• at least one array of blades attached to said inner surface of said cylindrical shell;
• an intake pipe whose outer diameter is less than the inner diameter of said cylindrical shell, wherein said intake pipe is mounted inside said cylindrical shell and prevents the incoming flow from making contact with said pump until said flow comes into direct contact with said at least one array of blades;
• an exhaust pipe whose outer diameter is less than the inner diameter of said cylindrical shell, wherein said exhaust pipe is mounted inside said cylindrical shell, adjacent to, and on the opposite side of said blades from said intake pipe, and prevents the exiting flow from making contact with said cylindrical shell;
• at least one means for significantly aligning the base of said blades with the inner surfaces of said intake and said exhaust pipes;
• a supporting structure;
• at least one means to allow said cylindrical shell to rotate freely in said supporting structure;
• at least one means of rotating said cylindrical shell;
• whereby preventing flow from adding weight, drag, and vibration to said cylindrical shell;
• whereby providing an efficient pump.
