 wind generator are a type of wind generator where the main rotor shaft is set vertically and the main components are located at the base of the turbine. Vertical wind generator offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width.

GreeF  wind generator is rugged, quiet, light, Omni-directional, and they do not create as much stress on the support structure. The vertical generator do not require as much wind to generate power, thus allowing them to be closer to the ground. By being closer to the ground ,they are easily maintained and can be installed on rooftop and similar tall structures.
