Do you mean micro wind turbine?
If so, please discuss.
This area is of great interest to me.

Plastic bottles are also "on the agenda" and have their pros and cons.
You need to understand forces and general available power levels and
work accordingly.
Not rocket science but more than meets the eye to do well.

I presently have a plastic $1 bucket based unit running that turns in
the lightest of breezes. Power at low speed is minimal - but I am
especially interested in low wind speed power regardless.

Rule of thumb

 Power =3D 0.6  x A x Z x V^3 Watt

A m^2, Z efficiency 0 - 1, V m/s

Well made Savonius can get perhaps 1 Watt / m^2 at 2 m/s
