Wind Turbine Design for Optimum Energy Output

Abstract Alternatives to traditional fossil fuel sources of energy are highly sought after. One alternative is wind energy, even though wind turbine output can be difficult to predict because of variability in wind gusts.

A simple horizontal-axis turbine was fashioned using a VCR tape motor to […]
