Giuseppe Zamboni
Giuseppe Zamboni (born June 1, 1776 in Verona , † July 25, 1846 there ) was a Catholic priest and physicist .
Giuseppe Zamboni invented for example in the year 1812 the Zamboni pile , a high voltage - dry battery with up to 4000 galvanic cells , and in 1820 the Zamboni swing , an electrostatic pendulum , which was driven by this battery. Since this pendulum apparently ran for many decades without consuming electricity, some people interpreted it as a perpetual motion machine . The electrical current required for operation is in fact very low on average and flows intermittently due to the charge transport of the pendulum body.
The Zamboni pendulum is a popular experiment in physics lessons and is mostly fed by an influenza machine or a tape generator . It is based on the repulsion of charges of the same name and the attraction of different charges: whenever the pendulum body transporting the charge touches one pole of the high-voltage source, it recharges there and is then charged with the same name and is immediately repelled. The other pole, however, now attracts it until it touches the other and in turn repels it. Such pendulums can also be made from metal balls hanging on threads.
Zamboni was appointed a corresponding member of the Bavarian Academy of Sciences in 1817 .
