THE WIND AND HYDRAULIC ENERGY OF THE ANCIENT GREEKS

In the Greek world, for the first time machines were operating without the work of humans or animals, but with the power of the wind and running or falling water. They even used ingenious ways of transmitting the movements of these machines. Characteristic examples are the “Greek” watermill of Strabon with the vertical transmission of interlocking wheels and the windmill of Heron with the converter of rotary motion to reciprocating motion.
