Abstract:
A flowing water turbine system comprising an upstanding column having a lower end fixed to a bed below a body of water having an upper surface so that the column is positioned to intercept a laterally flowing current in a the body of water, the column having an upper end extending above the upper surface of the body of water, a sleeve surrounding an upper portion of the column, the sleeve being rotatable about the column, an outer sleeve surrounding the sleeve, the outer sleeve being rotatable about the column with the sleeve and vertically movable with respect to the sleeve, a turbine assembly suitable for interacting with the laterally flowing current, a coupling apparatus coupling the turbine assembly to the outer sleeve for vertical displacement relative to the column, and control means positioned on the column above the upper surface for controlling the vertical position of the turbine assembly relative to the column.
