Generate Electricity with a Windmill For Science Project

A windmill for science project can be a great way to not only build something really cool, but it can also be a great way to learn about alternative energy sources. There are several windmill project ideas that you can utilize to explore energy topics. Some of theses ideas include:

~ Experiment with airfoil designs to create a variety of wind velocities

~ Determine how the size, shape and number of blades on a windmill impact its ability to generate electricity

~ Build and experiment with a PicoTurbine windmill like the picture on the left.

~ Research local wind conditions to see if it would be possible to light your community with wind power

There are two different types of windmills that you can build if you select a windmill for science project. The first type of windmill is a horizontal axis windmill and the second type is the vertical axis windmill. When selecting which type of windmill to sue consider which will be easier to build, which design will make it easier to experiment with and which design will wow the judges. Keep in mind that the larger your windmill is the more energy efficient it will be and the more cost effective the design will be.

One of the most popular windmill generators on the market today that is designed for science students and science fairs is the PicoTurbine. This mini windmill turbine stands about eight inches tall when assembled and it produces up to 2.5 volts, which is enough to power an LED light, which usually comes with the PicoTurbine kit. This model operates on a direct drive, brushless, single phase, permanent magnet alternator. You can use this experimental turbine to learn about the parts of a windmill turbine, as well as how these parts work together to generate energy.

When experimenting with windmill power generators, you need to be careful. There are two main hazards that you will need to protect yourself and your students against. The first hazard is moving parts. Moving parts can grab skin, hair and loose clothing and cause injuries. You can prevent injuries by keeping hair pulled back, by not wearing loose fitting clothing when working with a turbine and by manipulating the windmill’s parts only when it is not in motion.

Energy science projects, like windmill for science project, help kids explore science and develop important science skills.
