       Big Joule Thief Charger

       Here is the circuit I am playing with. It realy is a big Joule
       Thief or blocking oscillator. We take our wild AC output from
       the turbine. Maybe just 3-4 volts AC and rectifiy it to DC. Then
       we feed it to the Joule Thief where the transistor pulses the DC
       through a coil triggered by a small base current. When the field
       in the coil is energized the DC is blocked to the base and the
       transistor turns off. All that energy in the coil collapses and
       turns into a brief high voltage pulse. We use that high votage
       spike to charge a higher voltage battery than you could
       accomplish with the output from the turbine.
       Once the voltage from the turbine reaches the voltage of the
       battery the circuit is bypassed through the diode.
       This will also boost low voltage output from a solar panel.
