Vertical wind-powered electrical energy generation plant has curved blades attached to vertical axis provided with flaps which open when convex side of blade faces wind direction

摘要

The electrical energy generation plant has a vertical rotation axis (1) supporting curved blades (3) which are rotated by the wind, provided with flaps (2) which open when the convex side (8) of the blade faces towards the prevailing wind and which close when the concave side (9) of the blade faces in the wind direction.
