Abstract
A fluid flow power generating system is disclosed. The system includes a foil for accelerating the velocity of a fluid flow past said foil, to increase the fluid's kinetic energy. A turbine is located downstream of the foil, and at least partially behind the foil, and the turbine is driven by the fluid. The foil shields the upwind side of the turbine. A generator is also connected to the turbine for generating electrical energy. The turbine is mounted relative to the foil, so the position of the turbine relative to said foil can be adjusted to expose more or less of the turbine to the fluid flow. In one embodiment there are provided a plurality of individual systems which form a tower.
Claims15
A fluid flow power generating system comprising:
- a foil for accelerating the velocity of a fluid flowing past said foil, to increase said fluid's kinetic energy, the foil being located on an upstream side of said system;
- and
- a turbine separate from said foil and being located downstream of said foil, and at least partially behind said foil, said turbine including vanes sized and shaped to be driven by said fluid;
- a generator, connected to said turbine for generating electrical energy;
- and
- an adjusting means, whereby a position of said turbine relative to said foil can be adjusted to position said turbine between a retracted position behind said foil to a more exposed position to expose more or less of said turbine to said fluid flow.
