The Flow Stream Generator™ is a ducted rotor unit with augmenter tube.   The augmenter tube, which takes the form of an annular aerofoil, is used to increase the exhaust flow, dropping the pressure behind the turbine allowing it to operate above the Betz limit of 60%.  If the Betz limit can be overcome it will allow efficiencies of 60% or more. 

Results of initial tests, indicate improved efficiencies of 50%.
