Horizontal Vs. Vertical Wind Turbines | Education Seattle PI

Wind Direction and Speed. By contrast, a vertical turbine runs well regardless of wind direction, making it better-suited to urban areas with tall buildings where wind turbulence is a given. The vertical-axis design allows it to operate on lower wind speeds than is possible with the horizontal turbine....

What is a Windmill and How Does a Windmill Work

We begin with a brief definition of what a windmill is. It was originally a structure with sails, much like that on pre-industrial ships, and was originally used to produce flour from corn. In order to do this, the wind would have to prompt the sails to turn. They were also originally built by master craftsmen....
