The Simplest Wind Turbine Is The Most Satisfying

Sometimes there’s a satisfaction to be found not in the more complex projects but the simplest ones. We’ve featured wind turbines of all types here at Hackaday over the years, but HowToLou’s one is probably one of the least sophisticated. That notwithstanding, it does its job admirably, and provides a handy reminder of a parts source many of us might have overlooked.

At its heart is a motor from an exercise treadmill, which appears to be quite a powerful DC motor so that’s a source worth noting away for any future projects. To that he attaches the blades from a desk fan, and when placed outdoors on a windy day it generates enough power to run an LED head torch and charge his phone.

Of course, this most basic of wind turbines is not displaying its true potential in the video below the break. Were it mounted in a high position free from ground based wind obstacles it would no doubt catch a lot more wind, and in particular were it hooked up to a charge controller and a battery it could provide a much more useful power source. Then you could start optimizing fan blade designs… But this is a fun project that isn’t trying to masquerade as anything sophisticated, and it still has that potential.

This isn’t the first such simple turbine we’ve brought you.
