This clock is based upon a model designed by Leonardo Da Vinci.
Take a look here for an collection of historical anemometers : http://www.geag.de/txt_geschichte.htm
The idea was to use a device that has a different approach to measuring windspeed.
Instead of measuring rotation, we measure the movement of the pendulum in the design.
This design is really more of a conceptual thing. We made some prototypes for experimenting during the Korcula workshop.
