Moving vertical axis turbine foil

Abstract

A new movable foil for accelerating the fluid hitting the blades of a vertical axis turbine is presented.

1 . A vertical axis turbine, comprising:
 a. a movable FDD, peripheral to the blades, functionally contiguous to the blades of said turbine, and whose length is in the same axis as the turbine,   b. a means for moving said movable FDD.   
     
     
         2 . The turbine of  claim 1 , wherein the turbine is in a liquid. 
     
     
         3 . The turbine of  claim 1 , wherein the turbine is in a gas. 
     
     
         4 . The turbine of  claim 1 , wherein the movable FDD is a partial foil shape. 
     
     
         5 . The turbine of  claim 1 , wherein the means comprises at least one track. 
     
     
         6 . The turbine of  claim 5 , wherein the track is supported on at least one separate FDD. 
     
     
         7 . The turbine of  claim 1 , wherein the means comprises a tail vane connected to the movable FDD. 
     
     
         8 . The turbine of  claim 1 , wherein the means comprises a sensing-controller-motor system for adjusting the position of the movable FDD. 
     
     
         9 . The turbine of  claim 1 , wherein the movable FDD does not block the fluid entering the turbine. 
     
     
         10 . The turbine of  claim 1 , wherein the FDD partially blocks the fluid entering the turbine. 
     
     
         11 . The turbine of  claim 9 , further comprising:
 c. a second movable FDD, whether or not attached to the first movable FDD, partially blocking the fluid entering the turbine.   
     
     
         12 . A method of placing a movable FDD functionally adjacent to a vertical axis turbine. 
     
     
         13 . The method of  claim 12 , wherein the movable FDD is substantially located at a right angle to the direction of flow. 
     
     
         14 . A non-movable FDD, comprising an attachment for supporting a track.
