Abstract

The present invention relates to a vertical axis turbine 1 apparatus for converting movement of a fluid into electrical power and a method of manufacture of a turbine. The turbine can be installed on a flexible line 2, such as a cable, rope or stay. It could be used on the stay of a yacht. The main rotor 13, 14 of the turbine has least two helical blades arranged about the longitudinal axis with rotational symmetry, the blades being substantially identical in shape and having a lift-producing cross-sectional shape at least along a part of their longitudinal length. A generator 22 coupled to the main rotor 13, 14 and is contained in a generator housing 23.
