Savonius wind turbine design use type two blades with a diameter of 15.5 cm, a height of 10.9 cm and turbine weight of 51.3 g. The Darrieus wind turbine design uses type three blades with dimensions 21.8 cm x 8.7 cm x 2.3 cm. The weight of each blade is 51.3 g with the angle between the blades being 120⁰. The voltage of 2.5 V produced a minimum turbine rotation speed of 284.2 rpm and a maximum of 296.0 rpm. When the voltage was increased to 5.0 V, the minimum speed is 342.8 rpm and a maximum speed of 366.4 rpm. When given a voltage of 7.5 V, a minimum speed of 461.7 rpm and a maximum of 481.3 rpm were produced.
