Current power plant

The invention relates to a fluid power plant with a anstrombaren from a fluid flow turbine comprising a plurality of extending from a blade root to a blade tip and attached to the blade root on a rotating rotor wing, the wing elastically under the effect of fluid flow around an axis extending through the blade root axis can be rotated such that the pitch of the blades can be increased, wherein the blade root is fixed with the interposition of a bearing device on the rotor, wherein the storage means in tension with respect to the axis of compression, flexure and shear-rigid, but is formed torsionally.
