The invention concerns a Wells turbine, comprising a hub with a plurality of rotor blades having a drop-shaped profile orienting from a profile nose;

Wells turbine having passive rotor blade displacement

There is provided a free standing tidal power plant without a dam structure set to take up kinetic energy from a water flow. The tidal power plant includes a propeller-shaped water turbine in horizontal rotor configuration with rotor blades, the rotor blades having bidirectional profiles, wherein the rotor blades are fastened to a revolving unit, which defines a rotational plane, and an electric generator at least indirectly driven by the water turbine. Each rotor blade is associated with a first swivel axis and a second swivel axis, the first axis and the second swivel axis extending substantially along a longitudinal axes of a first coupling element and a second coupling element, respectively. The revolving unit includes a planar guide region having a sliding apparatus, a first guide groove and a second guide groove, the sliding apparatus connected to the rotor blade to transmit rotor blade forces.

Underwater power plant with passive control

The invention relates to a flow power plant, comprising a water turbine having torsionally rigid rotor blades, a drive train connected to the water turbine, which at least indirectly drives an electric generator and is characterized in that at inflow speeds v for which the flow power plant is designed, the water turbine is configured to be non-auto-restarting for tip speed ratios &#x3bb; below a predetermined auto-restart tip speed ratio &#x3bb;s where &#x3bb;s&#x2267;1.

Tidal power plant and method for operating said tidal power plant

There is provided a maritime current power plant park that includes a plurality of maritime current power plants, where each of the plurality of maritime current power plants has a rotor-like water turbine, an electric generator, and a drive train connecting the electric generator to the rotor-like water turbine. The drive train has bearing components for supporting the rotor-like water turbine. At least two of the plurality of maritime current power plants have differently dimensioned rotor-like water turbines, and the drive train of each of the at least two of the plurality of maritime current power plants is uniform.
