Description

Extraordinary example of perpetual motion with dry batteries  Zamboni type .

From 1805 to 1815 the Italian abbot Giuseppe Zamboni in Verona in relations with Alessandro Volta developed his famous dry cells and built some examples of watches or perpetual engines, so called because the battery charge had a very long life.

An instrument present at the University of Oxford (see photo) has been in operation since 1840!

This model consists of two dry cells made up of thousands of paper discs inserted into two glass tubes. A pendulum between the two batteries is attracted by the different polarities moving alternately.

This model was built in the second half of the 1800s by Franchini, a watchmaker in Bologna in northern Italy.

the conditions are excellent, but the batteries are now exhausted. Through the two green lacquered tubes we can see  the paper discs  . 

In the other photos: portrait of Giuseppe Zamboni, the Oxford electric pendulum, a model of perpetual motion in the collection of an Italian museum
