Virya

The Virya is an electricity generating windmill, which can be used to supply
power to lights and refrigerators to cool medicines. Compared to other highly
technical electricity generating windmills it is cheap to make. It costs about
2000 euro.

The windmill consists of a 12 metre high tripod tower. This is constructed in
such a way that the tower can be held over. It is made out of two parts that are
connected and disconnected with flange and bolts. This makes the mill easy to
transport.

On the head are the generator and the rotor. To keep the mill simple, no
transmission is used. This isn’t necessary for the type of generator used.
The rotor has three wooden wings with a combined diameter of 3.3 meters.
The windmill generates 1 kW if the wind speed is 6 Beaufort (Approxi-
mately 12 meters per second)

The WOT has adapted the windmill to our own insights. The original design
used a self-made generator, but this is not convenient for our target group,
because of the tools needed. Therefore we decided to use a commercially
available generator. Also a switch was designed to have the windmill transfer
wind power into a current suitable for the battery as efficiently as possible.
The windmill is used by WOT to make coffee in the Kiwanda. For this purpose a cable was laid from the Virya to the Kiwanda.
