ABSTRACT:
Vertical axis turbine apparatus is described in which a rotating blade turbine member mounted on a fixed base includes one to fifty, preferably two or three, upwardly and outwardly inclined spars. On each spar is set at least one aerofoil or hydrofoil section blade. If there is more than one spar, the spars are preferably held to one another via a plurality of guy wires.
