Number and Size of Blades of a Wind Turbine vs. Electrical Output
Science Fair Project Information
Title: The Effects of the Number and Size of Blades of a Wind Turbine on Electrical Output
Subject: Renewable Energy
Grade level: Elementary School - Grades 4-6
Academic Level: Ordinary
Project Type: Experimental
Cost: Low
Affiliation: Selah Intermediate School
Year: 2000
Description: A model windmill is built from balsa wood. A motor that is used as a generator is attached to the windmill. Different wind velocities are applied by a fan and output voltage is recorded by a multimeter. Those steps are repeated with different blade lengths and number.
