Vertical Axis Wind Turbine: All You Wanted to Know

22/04/2020  Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that’s why it got such a name. The engineers designed VAWT to make the turbine ...
