The Virya

The Virya, an electricity-generating windmill

The Virya is an electricity-generating windmill that can be used for lighting, cooling refrigerators behalf of medicines and charging mobile phones and laptops. Compared to other high-tech windmills which generating electricity the Virya is easy to build. It costs about 2000 Euro.

The mill exists of a three-legged mast which is 12 meters high. This mast is tiltable and consists of two parts. Those can be connected and disconnected to each other and can be fixed by a flange / bolt connection. This makes it easy to transport the windmill.

The generator and the rotor are located on the top. For reasons of simplicity and maintenance, no acceleration gear is installed. Regarding the type of generator, you even do not have to. The rotor has three wooden blades with a diameter of 3.3 meters. In wind with a force of 6 (about 12 meters per second), the windmill can supply 1kW power.

The WOT has adjust the windmill to their own insights. The original design was based on a homemade generator, but that’s not useful for third world countries. Therefore a commercially available generator is used. Moreover, an electronic circuit id designed to ensure that the windmill convert the wind as efficient as possible.

The windmill of the WOT is used for lighting and making coffee.
