The «aeolosphere» of Heron
(the first «steam-machine»of history)


It is the precursor of the steam-engine which, with the addition of a pulley, would have led the Hellenistic Era (had it not been interrupted by the political, economical and social factor and the Roman conquer) to the Industrial Revolution with unpredictable consequences to humanity.

There are two tubes over a boiler and around their curved ends there is a sphere with two blast pipes. When the water in the boiler is heated, it produces steam which is transferred through the two vertical tubes into the sphere and then released into the atmosphere with speed through the blast pipes causing the sphere to rotate.
