Other way around, perhaps? I "read" (my German is very rudimentary)a
history of Schempp-Hirth a few years ago and saw photos of wind turbine
blades being manufactured some time in the late 50s/early 60s. Does
anybody have any details?

I also understand that a lot of glider wing aerodynamics is actually a
spinoff from research paid for by wind turbine builders. Eppler, for
one, did turbine work I believe. Again, does anyone know any facts?
