Abstract Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Bibliography Judge, T.C., 2004.

Career Focus

If you like this project, you might enjoy exploring related careers.

	Aerospace Engineer Humans have always longed to fly and to make other things fly, both through the air and into outer space—aerospace engineers are the people that make those dreams come true. They design, build, and test vehicles like airplanes, helicopters, balloons, rockets, missiles, satellites, and spacecraft.			Mechanical Engineer Mechanical engineers are part of your everyday life, designing the spoon you used to eat your breakfast, your breakfast's packaging, the flip-top cap on your toothpaste tube, the zipper on your jacket, the car, bike, or bus you took to school, the chair you sat in, the door handle you grasped and the hinges it opened on, and the ballpoint pen you used to take your test. Virtually every object that you see around you has passed through the hands of a mechanical engineer. Consequently, their skills are in demand to design millions of different products in almost every type of industry.
	Wind Energy Engineer Every day the Earth provides us with many sources of renewable energy to power our lifestyles. Wind energy is an example of a renewable energy because wind is a naturally replenished source. But how can energy be extracted efficiently from the wind? Sounds like a job for a wind energy engineer! The wind energy engineer works on modeling, designing, and building wind turbines and wind farms. These engineers are passionate about wind, renewable energy, and the environment, and they enjoy applying their math and science skills.			Wind Turbine Service Technician Have you ever seen a wind farm or a collection of wind turbines? When the wind blows, the turbines rotate, turning the wind into energy for communities to use. But in order for the wind turbine to produce the greatest amount of energy efficiently, a wind turbine service technician must inspect, troubleshoot, repair, and ensure that the wind turbine is in good working order. This is a job that requires no fear of heights along with great mechanical aptitude and a good working knowledge of electronics.
