The Cal-ePower 12 kW turbine technology has solved many of the problems faced by both vertical-axis turbines (VAWTs) and horizontal-axis turbines (HAWTs). VAWTs have been known for their low efficiencies. One of the main reasons VAWTs are inefficient (<20%) is that the same wind that is driving the turbine is also impeding the returning blades. In other words, most VAWTs have to fight against their own design in order to produce power. Another problem faced by VAWTs is poor start-up torque. Our concentrator technology solves both of these problems by providing a two-fold benefit for the turbine: It increases the wind speed and pressure on the drive-side of the blades, thus increasing torque and RPM, while blocking wind from impeding the returning blades.
HAWTs have problems due to their need for laminar (non-turbulent) airflow: To reach heights that have steady, strong less turbulent winds, HAWT manufacturers continue to build taller and taller machines (now over 300 ft at hub height). These huge sizes in turn are the cause of the other problems associated with HAWTs: Interference with RADAR, wildlife fatalities, noise production, obscuring the view, and human safety concerns associated with ice throw and blade loss. These problems have caused government and the public to slow or stop the development of dozens of wind power projects. What is needed now is a solution in wind that can provide substantial amounts of power (up to 12 MW) without causing the problems associated with large HAWT wind farms. California Energy & Power provides this solution.
California Energy & Power has developed the Cal-ePower Cali 2.5 kW, 7 kW and 12 kW wind turbine solutions through extensive research and development and engineering efforts over the past 15 years. The latest Cali series 2.5 kW. 7 kW and 12 kW is a fifth generation design. Early on during the technology development that lead to CE&P's core Intellectual Property (IP) of our patented concentrator technology, CE&P partnered with California Institute of Technology (Caltech) to validate prototype testing results in order to ensure our design and testing process was being held to the highest standards. California Energy & Power has thoroughly tested our designs using the latest in CFD (Computational Fluid Dynamics) modeling, wind and water tunnel testing, and deployed our latest operational commercial prototype Cali 2kW in Q3 of 2017. Product development continued through 2019, and we plan to initiate limited commercial shipment in 2020.
