The Concentrator |
The CE&P 12 kW vertical-axis wind turbine is one of the world’s first industrial grade Controlled Wind Turbines (CCW) turbines using an uniquely designed airfoil concentrator and blade assembly. The invention here relies on the use of an airfoil or “concentrator” to direct and accelerate wind into a four bladed drive assembly, which, in turn drives a generator, which produces electricity.
The combination of the “concentrator,” blade shape and even the spacing of the blades from the center of rotation are key components of the invention. Using modern electronics, the turbine continually monitors the wind direction and velocity (by means of an anemometer and wind vane), turbine blade speed and the entire structure is driven into the eye of the wind for maximum optimum power production at a controlled and managed RPM. The invention and design of the design is protected by U.S. Patent No. 8,297,910, 774,338, and 10,669,985. The airfoil or “concentrator” directs the wind entering the turbine, and at the same time the “concentrator” shields the rotating blades from on-coming wind when the blades are rotating through to their return position. Due to the patented concentrator technology the CE&P Cali 2.5 kW, 7 kW and 12 kW wind turbine produce efficiency ratings of over 30 percent which almost doubles the efficiency ratings.. |
