Determine if multiple rotors will increase the electrical energy output of a horizontal axis windmill.
S
Determine if multiple rotors will increase the torque of a horizontal axis windmill. S Determine if teardrop shaped fairings added to a wind turbine will provide more power output as measured in watts. R The Effect of Various Wind Speeds and Blade Factors on Energy / Voltage Output R S The Effect of Blade Separation and Wind Speed on a Savonius Rotor Windmill R S Determine how much power a pinwheel generates at different orientations to a wind source. R Can a windbelt generate enough wave energy to oscillate a magnet and coil induction circuit to power a 1.5 volt lamp? R Determine the effect of the number of blades, pitch and the design of the blades on the electricity produced by a Darrieus-type vertical axis wind turbine at low, medium and high wind speeds. S Measure the current output of a small windmill generator and relate the power to the rate of rotation of the windmill's rotor. R The Efficiency of Different Savonius Wind Turbines R Can wind generated from highway traffic be captured to produce a useable source of energy? R Which is more efficient: a Horizontal Axis wind turbines or a Vertical Axis one? R R Compare the maximum power generated from various rotor configurations calculated using Betz's Law. R R R Determine if San Carlos has enough wind speed to support wind powered generators. R S Test whether wind turbines should be placed in laminar or turbulent flows in order to perform better. R Construct a windmill with two sets of rotors and motors and prove that it could generate more electricity than a windmill with only one set of rotor and motor. R |
