Wind harmonic generator?
I had this idea a while ago.
There's a nylon strap strung between two trees. It's let's say 2 cm wide and 5 meters long. A strong wind is blowing across it so that the strap is resonating, displacing through, say, 20 cm at 10 Hz.
What is the maximum power involved?
If you had one or more wire coils running the length generating current, what kind of efficiency over all could you expect?
I'm thinking of this as an ultra cheap and easy means of wind generation.
