The team constructed a new wind turbine prototype and explored its characteristics. They conducted experiments to determine the turbine's speed at different distances from a controlled wind source, and to measure light-dependent resistor and current values. They created a Google site to share their progress and will publish it this week. Their aims were to characterize how turbine speed is affected by wind and to find the optimal distance between the turbine and wind source.

5. For Cylinder Fan: Height = 20.5 cm Height from Bottom to middle = 10.5 cm Diameter = 16.3 cm Thickness of Fan Divisions = 0.2 cm Height of Each Division = 9.5 cm 36 Divisions equally spaced. For Top Wood: Width = 24.5 cm Length = 20.4 cm Thickness = 1.85 cm For Side Wood: Width = 20.6 cm Height = 17.3 cm Thickness = 4.2 cm Prototype Dimensions

6. LDR Sensor LDR -Light Dependent Resistors that are very useful in light/dark sensors. Typical resistances (at dark surrounding environment) ranges up to a 1 Mega Ohm extreme but drops dramatically almost instantaneously after being illuminated. LDR Values Obtained Ambient Light Resistance Value (F325 Room Light)= 6.88k ohms Dark Light Resistance Value (By covering the upper optical sensor)= 244k ohms

8. Current Measurement The set up is done by connecting a 200 ohm resistance (load) in series with the Multi-Meter in order to make a suitable connection for the configuration. The experiment is done on both the motors available as connected in the prototype available.
