Scaling of a windbelt - how small? Answered

How small can a windbelt be made? I am hoping it is possible to make it at least 10cm

Discussions

The limit won't be size, but wind. Smaller belts will probably need much higher wind-speeds to start them vibrating.

As small as you can make a tight strip of flexible material and a generator to capture power from it (assuming you want to generate power)- you can make a "windbelt" by putting a blade of grass between your thumbs and blowing :) The principle will probably work down to tiny constructions, although with household materials you are probably limited to a few centimetres long, but at that size the power and efficiency will be abysmal.

Why small? You could make them absolutely tiny...
