  • Vertical-axis wind turbines: what makes them better

    31/10/2014· While most wind turbines are configured for rotating about a horizontal axis, a relatively newer type of wind turbine- known as a vertical-axis wind turbine (“VAWT”) – is configured for rotating about a vertical axis. One advantage of this arrangement is that the wind turbine does not need to be pointed into the wind to be effective, which is an advantage on a site where the windОнлайн-запрос
