Build a Wind Turbine

Step 6 of 7: Design and test the blades

Place a few small, wooden dowels into the holes of the hub. Create wind using a hair dryer or fan. Check the multimeter to see how much energy is generated.

Using a variety of  materials, design different blades for the wind turbine. Consider the weight, smoothness of surface and number of blades needed. Attach the blades to the dowels using tape.

Turn on the hair dryer or fan again and test the turbine with each type of blade you design. How does the electrical output differ? Test the turbine with different wind speeds, such as low, medium and high fan settings. Does the wind speed affect the electrical energy output?
