<p>The invention relates to apparatus and methods of fluid energy conversion. One embodiment relates to a tube for a fluid energy converter. The tube may include a generally cylindrical and hollow body having an interior surface, an exterior surface, and a longitudinal axis. Another embodiment relates to a fluid energy converter (100) having a longitudinal axis and a rotatable tube coaxial about the longitudinal axis. The rotor (1) can have a tube, a front set of blades (30), a back set of blades (40), a nacelle (50) with helical vanes. The tube may be provided with external and internal grooves. Furthermore, a method of operating the rotor, a method of manufacturing the tube and the structural lay-out of the tube are described.</p> |
