Wendelstein 7-X made in Germany, for example.

The complex curvey magnets (blue objects) might be easier to make using a bundle of extrusions that can be bent and curved arbitrarily.  Inner voids can hold the superconducting magnets.

Windmill Blade Inner Beams

Twisted and tunable bending.

-

The blade could be divided into slidable sections where the bending can be locked or relaxed.

-

Possible blade optimization depending on wind conditions.
