The “vertical axis wind turbine” has turbine blade designs either vertical or in the shape of an egg beater, and similar in many ways to the wind powered centrifugal ventilators seen on chimney’s and flue’s. The vertical axis wind turbine blades are attached to a central vertical shaft and which has specific advantages over the horizontal wind turbine designs. We supply micro vertical axis wind turbines built with aluminium alloys/carbon composites for residential, commercial and industrial applications.
