Turbines are machines that generate continuous electrical power using blades driven by air, gas or water to turn an electrical generator. Almost all of our electrical power is made by turbines these days. Water gets heated up and produces steam, which then gets directed through the turbine and generator - voila electricity!
You could go green and buy your own wind turbine so that you could generate your own free electricity, but that can be costly, and who wants to pay for something that's free? Instead, check out the Instructables below and learn how you can make your own turbine!
