Wind power is a renewable source of electricity. Traditionally, it has required steady and steady wind to be effective. The old "propeller spins" with horizontal shaft cannot withstand turbulent winds, although it can contain as much energy. The so-called vertical wind turbines have not previously reached the same efficiency as the propeller-driven, but have now been updated with more shafts and thus a whole new ability to take advantage of turbulent winds. They are also effective on a smaller scale and Power One has now decided to use these instead of the traditional ones.
Traditional propeller-type windmills use the “horizontal axis x propeller type” method, but the horizontal axis is difficult to respond to changes in wind direction, and the propeller type has a risk of runaway velocity due to strong winds. A horizontal axis propeller type windmill can generate power with high efficiency when the wind direction and wind speed are bothstable, but it is difficult to cope with sudden changes in wind speed and direction. The wind direction of the tropics is not stable, and under such circumstances, the vertical axis Magnus wind turbine can achieve stable operation and achieve a higher capacity utilization rate.
The "vertical axis Magnus type" system is compatible with wind in all directions because of the vertical axis, and by using the Magnus type, the rotational speed of the wind turbine can be kept constant according to the wind speed by controlling the rotation of the cylindrical blades. can. By controlling the rotation speed of the windmill, stable power generation is possible without runaway even in sudden strong winds. The wind environment in the tropics is very harsh for windmills that are subject to drastic changes in wind direction and speed and among them, the vertical axis Magnus wind turbine can generate power stably, and it can be expected to dramatically improve the operating rate of the wind turbine. In addition, by using a cylindrical blade instead of a propeller, the manufacturing cost can be greatly reduced, so it is possible to supply inexpensive power using renewable energy.
Tanganyika is a fantastic lake. It is huge not only to the surface but also to the depth. It is also pure and undisturbed with one of the world's largest biodiversity. Because of its surface, the winds get a smoother flow and do not become as turbulent. Therefore, the shores of the lake are suitable for the traditional propeller-driven wind turbines. However, these are both costly and difficult to maintain. They also have a great aesthetic influence. Since the modern vertical wind turbines do not require proximity to the lake's steady flow, they can be placed a little anywhere, preferably up in the mountains.
Power One will therefore invest in a larger number of these vertical small power plants up in the mountains instead of a large propeller-driven power plant at the lake.
