The present invention is a vertical wind turbine having a turbine with a plurality of blades or wind vanes. The blades are constructed and attached to the shaft of the turbine so as to allow them to twist open to present more surface area to wind currents when a threshold rotational velocity is reached. Also presented are a novel outer shell that is placed over at least part of the shaft and a novel turbine blade.
