Abstract
A power generating system wherein a turbine is mounted on top of a tower or tethered underwater. The turbine includes a rotor having a main blade section connected to a rotor hub and an extender housing mounted on a top surface of the main blade section. The extender housing has an extender blade stored therein. An adjusting device positions the extender blade between a retracted position within the extender housing and an extended position to expose more or less of the rotor to the fluid flow. A generator is connected to the turbine for generating electrical energy.
