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 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 and 7,774,338. 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 of other vertical-axis wind turbines designs.

CE&P is Working with the University of California, Berkeley

​California Energy and Power (CE&P) announced the collaboration with the University of California, Berkeley (UCB) to further the development and optimization of CE&P’s CALI Series vertical axis turbine technology. This project involves a 1 year, 2 phase collaboration to further the efficiency and production output of the CALI series Vertical-Axis-Wind-Turbines (VAWT’s). The first phase includes the revision of systematic optimization of the aerodynamic shape and efficiencies of an individual CALI series turbine’s production design. The second phase includes the research of “Dense-Packed” CALI series turbines in array of a triad. This triad is the combination of 3 CALI series wind turbines working together in a cluster. With revisions along with these two project phases, CE&P and UCB intend to increase the optimization of Vertical-Axis-Wind-Turbines to surpass the energy output of traditional horizontal-axis-wind-turbines (HAWT’s).
