Abstract (en)
[origin: WO2006065248A2] A diffuser-augmented wind-turbine assembly in which the diffuser has a cylindrical central section rotatably supporting a rotor drum which in turn supports turbine blades without requiring a central support shaft. Wind energy drives the turbine blades and rotor drum, which in turn drive a generator of electrical power.
