Note: Please read through this procedure first before performing the experiment, as the
elements of the process go fast and require prior knowledge of what is about to happen.
Procedure:
1. Place the table fan directly in front of the wind turbine then switch it on to its highest
(fastest) setting. A plot similar to the one below should begin to appear. Notice that the
voltage (green line) increases to a maximum level almost instantly. The maximum
voltage level may vary given your fan setup and speed of air movement. Also notice the
ripples as the plot proceeds. This is due to the wind turbine's 3-phase output.
