Abstract

A vertical axis wind or water turbine has at least one rotor 1, 2 with drag type blades 3, 4 shaped as hollow aerofoil shaped blades which are convexly shaped and which narrow towards leading and lateral edges. The blades 3, 4 may be asymmetrical or symmetrical. Plural rotors may be counter-rotating. The blades may be connected to the rotor by means of winglets 41, to allow pitch (figures 52-55) or tilt (figures 60-63). Circular fluid deflectors/diffusers may be placed above and/or below the rotors, and may have collar panels mounted on them. Each rotor may have more than one row of blades, which may be vertically aligned or mis-aligned.
