The wheel uses a person to derive strength from running water

In Saqiya, people use animals to turn the axle of the wheel carrying the tractors, and the tractors scoop up water as they reach it, then rise. And the water is still.

But what do you think if the water is not still?
What do you think if the water is running, especially dripping? Then, instead of jars that scoop water, the wheel carried plates like the tips of oars fixed around its perimeter?

The running water hits the plate, causing the wheel to turn, and the plate rises to be replaced by another plate. The water hits it, so it rises and the wheel turns.

Thus, the water moves the wheel, which has short, wide plates or paddles that we call feathers, and the flowing water becomes a source of force, energy, and movement, giving it rotation to the wheel, which we used to call it. It is given by its axis. The axis rotates on itself horizontally, and from its rotation we derive the strength with which we can manage whatever we want in various ways.

- Flowing water provided Europe with strength for 14 centuries:

This power derived from the Water Wheel is the basic power on which the Romans relied, especially when there were few slave slaves among them, and Europe relied, for a period of 14 centuries, in every industry or industrial work, such as pumping water, breaking stone, and in manufacturing paper, and in tanning,
In blacksmithing, spinning and weaving.

(A blacksmith factory, in which you see the blacksmith hammering his iron, after he took it red out of the coal stove, on his anvil. And you see the hammer landing on the anvil and striking the iron. And you wonder who landed on the anvil and struck it? And we ask who moved the blowers and blew the wind into the coal and its flame increased? Then you You look outside this blacksmith factory and you find the reason for all of this: it is a rotating water wheel. Water flowed at the bottom of it and turned it. And from the rotation of its axis the factory derived its energy.)

(The Egyptian waterwheel is something similar to the structure of the Roman mill called Vitruvian, because its wheel that raises the water is standing, and the wheel that the bull turns is horizontal. Therefore, other wheels must be in between the two wheels to change the direction of rotation.)
