The water inside was heated, and as the steam came out of the
holes, the ball spun. However, it was considered one of the
useless oddities that scientists make and was mainly used as a
toy to impress the staff. But it can be said that it is the forerunner of antiquity that
came closest to what we know today as the steam engine. The
power of steam was known long before the appearance of the
first efficient machines in modern times.

scientist and engineer Heron of Alexandria describes devices
that use the power of steam to automatically open the doors of
a temple or operate a small turnstile. In the 17th century, people began to understand the concepts
of vacuum or atmospheric pressure and the behavior of gases.
And soon there was an attempt to use the power of the vacuum
to harvest energy.
