Max Current                                                     42.2 mA
Max Wind Speed                                             19 mph
Max Voltage                                                     8.5V
Min Wind Speed                                              6 mph
Calculated Power (Wattage)                            358.7mW

     The data above is from experimentation of the wind turbine on the top of the Drexel garage. The maximum power output increased as the wind speed increased to 358.7mW. The data suggests that there is an increase in wind flow around and on top of buildings due to wind vortexes accumulating increasing wind speed around edges.This phenomenon is important to our design since more wind speed means more power, however placement of these wind turbines on top of building leads to complexities such as connecting the power output to the power grid, or be able to maintenance the urban wind turbine.
     The video below is proof that the urban wind turbine generates electricity for a 1.5 Volt light bulb.
