Shrouded vertical axis dual-turbine generator

摘要

The shrouded vertical axis dual-turbine generator is a system comprising a structure in the shape of a double airplane wings symmetrical foil, having a vertical axis turbine set into each camber at each side of the foil. The aerodynamic shape of the leading edge of the foil increases the speed of the water or air current incoming toward the generator. The trailing edge of the foil creates a slip stream which reduces turbulence. Movable shutters on each side of the foil structure control the amount of current to the turbines and sheltering them from storm and debris. The turbines have a modular design and can be made of a stacked number of blades.
