Do not attempt to replicate the test in the video as the spinning blades can hurt you.
I have a small Epson dc motor which can be used to make a wind turbine to charge AA batteries. Initial tests was 2 volts with a drag type blade. I made the blade more aerodynamic and was able to increase the voltage to over 4 volts. Subsequent testing with a more flattened blade yielded over 6 volts. I will try to use aluminum flashing for my next test. This together with a dc to dc step up converter can regulate the output to a pre-detemined voltage and make the motor more usable. With a leisurely wind, the motor should be able to put out 2 volts or so which should be enough to charge a set of AA batteries in parallel. I can use a schottky diode to reduce the voltage drop between the wind turbine and the batteries.
