Perpetual Motion Claim.

New York Times 100 years ago today, July 23, 1913:
Italian Thinks He Has Solved the Problem of the Ages.
    TURIN, July 22.— Tests have been made before scientists here of a machine invented by a mechanician named Florio. by which, it is claimed, perpetual motion is demonstrated.
    The basic principle underlying the method employed is the contraction and expansion of gas. The machine collects the caloric energy of the air, which is inexhaustible, and transforms it into mechanical energy.
    The air is supplied automatically and the apparatus is in continuous motion by reason of the passage of the gas from the warmer atmosphere to the colder water.
