Abstract (en)
[origin: WO9630647A1] A support structure for a vertical axis wind turbine in which the airfoil blades (1) are spaced radially from a spinning tower (3) by support arms (2) with the airfoil blades (1) being substantially straight and vertically oriented. The weight of the spinning tower (3) and the associated structure is supported by a load bearing (8) located on a fixed post (9) at approximately the mid point of the height of the airfoil blades (1). A lateral bearing arrangement (25) is associated with the lower end of the spinning tower (3) and locates the spinning tower (3) laterally in relation to the fixed post (9).
