Abstract
A wind-powered electric generator using a concentrator structure and a focusing surface for focusing a wind stream onto a plurality of turbines, one of which is located within the concentrator structure, thereby providing for smaller structural size, as well as increased conversion efficiency.
Claims6
A wind-powered generator comprising
- concentrator means for concentrating and focusing a fluid flow, the concentrator means having a flow chamber which defines a fluid flow path, a flared mouth which is located at one end of the flow chamber, a focusing surface which is located at the opposite end of the flow chamber, and a coupling port, the focusing surface having a focus located within the flow chamber;
- a turbine housing having an inlet and an exhaust port, the turbine housing being positioned within the flow chamber so that the inlet opens to the focusing surface focus, the focusing surface and the turbine housing inlet being positioned relative to one another so that the focusing surface receives the fluid flow from the fluid flow path of the flow chamber and focuses the fluid flow into the turbine housing inlet;
- an exhaust tube, open at both ends, extending from the exhaust port and through the coupling port to the exterior of the concentrator, the exhaust tube being communicatively coupled to the exhaust port so that the fluid flowing into the inlet is exhausted from the turbine housing to the exterior of the concentrator;
- a first turbine positioned in the inlet for rotation in response to fluid flowing into the inlet;
- and
- generator means for converting rotational motion into electrical energy, the generator means being communicatively coupled to the first turbine so that the rotation of the turbine is converted into electrical energy.
