A Turbine Rooted in the Concept of "Keep it Simple"
The Concentrator |
The CE&P 12 kW vertical-axis wind turbine is one of the world’s first industrial grade vertical wind turbine 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 by an electric motor into the eye of the wind for maximum optimum power production at a controlled and managed RPM. The invention and design of the “concentrator” (U.S. Patent No. 8,297,910) increases the power output of the four bladed assemblies by approximately 400 percent when compared to the turbine without the concentrator. 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 (validated by Caltech) which almost doubles the efficiency ratings of other vertical-axis wind turbines designs. |
