Wind turbine test again

Bent a nut to stop wheel from free spinning. Now bike axle spins the
whole drill head. I had a friend hold and watch the multimeter. On
setting #10 had constant 3.0 and highest of 3.22v from hand spinning. On
setting 24 I got as high as 2.90v and on setting 1 got 0.32v Im thinking
I may get 12v if I attach the drill to a stationary bike. Would be a
great exercise activity. But maybe 7mph winds would spin it. All depends
on constant wind speeds in the valley. Will get a blocking diode this
week. Have to find a way to stop it from spinning opposite way which
makes the volts negative. I really can't believe this simple tech works
for charging batteries..
