"With great enthusiasm for the new type of wind power, we will continue to work hard with our team." In the evaluation of the J-TECH STARTUP brand, a company named Challenergy (deputy director and CEO: Shimizu Dunshi) was named as such. The company is developing wind turbines that meet the climate and soil conditions in Japan. The goal is to achieve a power generation device that does not take into account typhoon and wind direction changes. Compared with Europe, the process of importing wind power in Japan is slow. One of the reasons for this is that Japan's wind power and wind direction are unstable, and it is often subjected to strong winds such as typhoons, and the devices are easily out of control and damaged. In this case, it may be possible to abandon propellers common in Europe and try Other methods. It was under this idea that Challenergy began to develop "vertical shaft type Magnus wind turbines." Using the same principle as the curve ball of baseball, the "Magnus effect", the generator is rotated by three cylindrical rotating bodies. The principle of the Magnus effect is that when the rotating body is placed in a fluid, the fluid-side flow accelerates with friction with the rotating body, and the other side, on the other hand, exhibits a slow flow. This difference in flow rate produces a pressure difference that creates a force (magnus force) in the direction perpendicular to the flow of the fluid. Challenergy's wind turbines arrange the cylinders on concentric circles, generating a force along the tangential direction of the circle, thereby turning the shaft. There are two reasons why this type of wind turbine is suitable for the weather conditions in Japan. First, because of the vertical axis design, no matter what kind of wind direction can be turned. Secondly, the rotational speed of the vertical shaft can also be adjusted by adjusting the rotational speed of the rotating body. The wind turbine has been conducting field tests in the southern city of Okinawa since August 2016 and has taken the first step towards practical application. The goal is to mass market a 10kW class device in 2019. Universal A/C control system & Remote Ningbo Kyson Cool Electronic Technology Co., Ltd. , https://www.kysoncool.com
