The following was a question and answer session with Carl Wilcox during the 1973 Wind Energy Conversion Systems Workshop in Washington, DC.[1] Wilcox had been a member of the Smith-Putnam team.[2] Beauchamp Smith of the S. Morgan Smith Company also attended the conference and gave a presentation just before Mr Wilcox. The “COMMENT” below was likely by him as he addressed Mr. Wilcox as “Carl.”[3] There were other luminaries at this conference, including Ulrich Hütter,[4] Jean-Marc Noël,[5] and William (Bill) Heronemus.[6]

It was common knowledge on California wind farms in the 1980s that one way to stop the rotor from spinning out of control was to somehow get a rope tangled in the rotor. The rotor would then wind up the rope, wrapping it tightly around the main shaft, slowing the rotor if not stopping it. To get the rope into the rotor, it was necessary to shoot an arrow towards the rotor with a line attached. If successful, the spinning rotor would do the rest.
