Second Experiment- A taller prototype with new angles. The two blade turbines: New angles of 28(°), 29(°), 32(°), and 34(°) increased wind flow for comparison with the new findings of four blade turbines. The new four blade turbine angles are: (<)15(°), at angles of 13(°), 12(°), 11(°), and no (<)10(°). The new turbine is connected to a generator, 12 volt light bulb, and a 12 volt battery was added for energy storage. The volt meter gave higher readings and the light bulb lit up with power generated by greater wind flow. The tower height was increased to 36 inches. The new turbine blades are 32 inches long. The base plate is 18 inches in diameter to accommodate the new tower height.
