I am impressed to read that during the 1760's a man named James Cox built a perpetual motion machine in the form of a self-winding clock.
The mechanism uses changes in atmospheric pressure, harnessed via a mercury barometer, to wind itself indefinitely.
The clock still exists in the Victoria and Albert Museum of Great Britain, although it is no longer active.
