Damon,
To give you an idea of what you are up against
http://www.fieldlines.com/comments/2005/11/10/191155/99/2#2
as an example...I did a similar weight thing with
a stepper motor which took a 1.5 pound weight
traveling about 12 ft. in 10 seconds to light
this 2 led light at full normal brilliance.
Now this light will shine with 4 AA batteries
for about 24 hrs. by that time the voltage has
dropped to about 5 volts.
I built a VAWT this size:

It was 8 inches x 3ft. high it turned the stepper motor in a 10mph. just barely fast enough
to light the lamp about 2/3 normal.
I think your turbine is just about big enough
to overcome the friction in your generator
bearings. IMHO.
