To create an attractive form of wind power, attach a sheet
along the top and bottom to a series of push rods that
rotate a crank
shaft as the sheet oscillates in the wind.
This is clearly not the most efficient method, but pretty.

(and tearing itself apart).

Not flags... sails.

||I actually worked on such a contraption, with a
inventor. We used strings to pull a small oscillating
magnets device (straw with small magnets inside
windings around it).
||It gave too little power so we abandoned the idea.
And moved on to a similar but better idea. (Similar
to my ground sail idea).
||I have videos of giant flags constantly billowing day
and night winter and summer, for the
presentation we were preparing.
||Some fellow made a small wind-power generator out of an oscillating taut ribbon and magnets (how do they work?) and coils.
||HA! I knew it would work. [link] Thanks [baconbrain].
