Why am I not a designer ?!

Imagine an advertising sign- "rotator" sort of S-shaped, if you look at it from above. Oh well, you have seen this exactly - if there is even a small breeze, such things always turn in the same direction. Understand what I mean?

Fine. Connect it to the generator (the coils can be placed on the wings, and the magnets - on a fixed support, well, this is the details). Power generator direct to LEDs, for example. LEDs are also located on the wings of the rotator. There is wind - there is light.

What for? Place such things on the rocky coast - a free lighthouse, the brightest in the storm. On the narrow streets - free lighting.

Oh, fantasy. I can’t even make visualizations; imagine everything just by the description.
