A fluid connection for a hydromotive machine or fluid-control valve having a first duct and a second duct. The first duct includes a mid-portion between a first end of the first duct and a second end of the first duct that has a non-circular cross-section. A second end of the first duct is wholly within the second end of the second duct. A first end of the second duct is wholly outside of the first duct.

A method for decommissioning a wind turbine blade includes separating a root section of a turbine blade from a tip section of a turbine blade, and laterally cutting the tip section of the turbine blade into a plurality of separate tip subsections. Each tip subsection is cut along its length, flattened, deposited into a compacting and bundling apparatus, and compressed. The compressed tip subsections are bundled in the compacting and bundling apparatus with banding material to form a bundle. The bundle is removed from the compacting and bunding apparatus and loaded onto a transportation vehicle.
