Looking at Wind Turbines From a Different Angle

Posted by in categories: 3D printing, sustainability

When we think of wind turbines, the first thing that usually comes to mind is the typical Sim City-esque type – 3 blades, gigantic, and wired into the municipal power grid. In truth, the world of wind power generation is far more varied indeed – as [Vittorio]’s vertical-axis wind turbine shows us.

So what exactly is a vertical-axis wind turbine, you ask? Well, rather than the typical setup with blades rotating about a horizontal axis, as in typical utility turbines or a classic electric fan you might use to cool off on a sunny day, instead a vertical axis is used. This necessitates a very different blade design due to the orientation of the rotational axis relative to the flow, so such turbines can be quite visually striking to those unfamiliar with such designs.

[Vittorio]’s design is a great way to get to grips with the type. The blades and supports were initially created out of PVC gutter channel, though 3D printed versions have also been developed. The motion is turned into electricity by using a simple brushed DC motor as a dynamo.
