¶ Windmills
Index Entry
Windmills:
"In windmills the total frontal area is what counts. Just as that is what counts in designing buildings. We have a penetrating body in a penetrating medium. The bigger it is the more low pressure it builds up.
“A windmill is designed for average wind speeds. In the Greek isles, at Kykonos, they furl them at over 30 m.p.h.; the furling is like the gimballing of an umbrella.”
