FLORENCE (Ball clock) I decided to build this clock only to reuse and simplify the Anachrone, for such a good engine deserved to be optimised.
After several months of prototype testing I managed to simplify it to the point where one falling ball was communicating enoughenergy to the pendulum for one hour. That's an improvement by a factor of 3599 over the Anachrone. The rest was mereimplementation... To be torsion free the chassis had to be triangular (a rectangle experiences a 1/100 mm torsion per oscillation, which is enough to dissipate the pendulum's energy).
