(EP830506-A1)      An array of helical turbine units (304) may be arranged vertically or horizontal. Each turbine unit comprises one or more helical blades (302) having an airfoil profile. The modules are mounted on shafts (322) supported in a lightweight structure (316) which is anchored by guy wires (318).    The turbines may also be mounted along each side of a ship to collect wave motion energy to power a propeller fitted at the end of the turbine shaft.    USE/ADVANTAGE -   May be used to collect energy from ultra low head fluid flow or to raise or lower a vessel in the water or to drive ships' propellers.
