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 section. An adjusting device positions the extender section between a retracted position within the main blade section and to an extended position to expose more or less of the rotor to the fluid flow. The adjusting device includes a first web-engaging wheel anchored at a hub end of the main blade section and a second web-engaging wheel anchored at a distal end of the main blade section. A web is wound around the first and second web-engaging wheels. The extender section is attached to the web at a hub end of the extender section. A generator is connected to the turbine for generating electrical energy.
