This practical book deals with the technology of small-power wind turbines as opposed to widely diffused industrial wind turbines and wind farms. It covers the most common wind turbine technologies in the small power segment: horizontal axis both for electrical generation and water pumping, vertical axis of the Darrieus type, and vertical axis of the Savonius type. With each chapter following the same didactic scheme―a theoretical explanation and practical examples showing calculation procedures―it allows anybody with basic technical knowledge to design and build a small wind turbine for a...

The reasons for the weak power generation of lantern wind turbines are as follows: 1. Because of its own design reasons, the power generation of Vertical-axis wind turbines is far less than that of horizontal-axis wind turbines. This problem is a worldwide problem and has not yet been solved. But its advantage is that it can be started in the breeze, beautiful appearance, and not easy to break. 2. Because of the blade, the fan speed can only slow down when it reaches a certain speed, and it cannot continue to run at a high speed. Therefore, the ideal power generation cannot be achieved. 3. Mos... [Read More]

From Manufacture: A wind turbine is a popular name for a device that converts kinetic energy from the wind into electrical power. Technically, there is no turbine used in the design, but the term appears to have migrated from parallel hydroelectric technology (rotary propeller). The correct description for this type of machine would be aerofoil-powered generator. Our Aleko Wind generator will provide you with the power you need for your home or your business. Product Description: Low start up speed, high wind energy utilization, beautiful appearance, and low vibration. The generator has... [Read More]
