In the early 1800s many Americans were experimenting with different new waterwheel designs. One of these men, Calvin Wing of Maine, patented the reaction wheel in October 1830. It consisted of a hollow iron disk with a large hole on one side to allow pressurized water in from a penstock and six angled holes on the rim to allow water to exit. The force of water squirting through these six angled jets turned the wheel in reaction to the force of the exiting water. The reaction wheel, in some ways the predecessor of the modern turbine, operated on water pressure obtained by confining the water as it fell. It was fairly efficient, could operate in a wide range of water levels, including flooded back-water conditions. Its cast iron construction made it extremely durable, so it didn’t rot like a wooden wheel. It was also compact, achieving high speeds and generating a lot of power while taking up little space and eliminating the need for costly gearing. It did require precision manufacturing and installation, and thus was somewhat expensive compared to a simple wooden wheel. The 1830s miller who bought one was taking a risk and making an investment in new technology.
Modern Hydroelectric Turbine Water power is still a vital source of energy in the 21st century. However, instead of generating mechanical energy to be used on-site, the energy of falling water is converted to electrical energy and transmitted for use elsewhere. In a turbine water is smoothly funneled into a restricted space where it turns the turbine’s blades which are connected to a gear box and electrical generator.

Here the waterwheel performs two tasks, one with the crank and one with the cam. The crank in the back works a bellows to stoke the smith’s furnace. The cam on the right (D) operates a trip hammer (E).

This milling complex at Arles in Roman Gaul had 16 waterwheels that could mill enough grain to feed 80,000 people. Since the local population was probably only about 10,000, we figure the milling complex at Arles was the center of a vast redistribution network, indicating the large scale of trade in the Roman Empire.

Two watermills operating between bridge abutments. Notice the spiral shaped millstone in the foreground being taken in the replace one that is worn down.
The numerous depictions of waterwheels in European art are further evidence of their ubiquity.

The first mechanical clock was built during the Sung Dynasty in China around 900 C.E. It was an astrological/astronomical clock with seven faces to mechanically track the motion of the sun, moon, and five known planets at that time (Mercury, Venus, Mars, Jupiter, and Saturn).
It was also a water clock with sophisticated machinery to regulate the flow of water in order to keep time. The clock was a royal monopoly to help emperors decide propitious times for acts of state, such as making war or peace. The emperors relied on it so much that, when an ambassador to the north reported that the heavenly bodies were not in line with the clock, the emperor replied that the clock was right and the sky was wrong.
Somehow, the idea and design of the Chinese clock made its way west, where and Italian, Giovanni di Dondi, built the most sophisticated clock of the Middle Ages between 1348 and 1364. Like the Chinese clock, it had 7 faces showing the movements of the sun, moon and five known planets. It had no hourly dials, which he said were too simple, and was so sophisticated that it wasn't duplicated until the 1800's. One difference from the Chinese model was that his clock was weight driven with a mechanical escapement system since water froze in the wintertime. There is a working model of di Dondi’s clock in the Smithsonian Institute.
Clock fever While some of the earliest European clocks, such as the town clock in Prague, continued to chart the heavens for astrological purposes, Europeans scaled them down just to keep daily time
Is it us keeping time…. The first clock recorded as just striking equal hours was in Milan in the early 1300's. From then on, it was a matter of pride for every medieval town to have its own clock tower, and they appeared in rapid succession in Genoa (1353), Florence (1354), Bologna (1356), Ferrara (1362), and Paris (1370). Sighisoara,Romania Milan St Albans, England Ottery, England
…or time keeping us? However, it was the clock in Paris that triggered a real turning point in Western Civilization when Charles V of France ordered the churches to ring their bells on the hour in coordination with the clocks, thus subordinating the Church’s schedule to that of secular business. While Charles may have thought that he was capturing time, to a large extent time was capturing us, tying us to ever more precise schedules over the coming centuries so we know exactly when we have to get up, be at work, eat lunch, get off work, pick up the kids at soccer practice, and get to watch our favorite TV show. I could continue this list, but I don’t have time.
Clocks and clock-like devices even started showing up in medieval art, indicating a more mechanistic view of the universe centuries before Newton’s work. Along those lines, there was an emerging cultural mindset that was tuned into mechanical principles and how to exploit them. Even more striking was an expectation, replacing the static unchanging view of the universe that such innovations would keep coming indefinitely. In short, people were starting to think in terms of something called progress.
"Never will we find truth if we content ourselves with what is already known... Those things that have been written before us are not laws but guides. The truth is open to all, for it is not yet totally possessed."--Gilbert de Tournai (c.1200-1284) "Not all the arts have been found; we shall never see an end of finding them. Everyday one could discover a new art...It is not 20 years since there was discovered the art of making eyeglasses which help one to see well, an art which is one of the best and most necessary in the world. And that is such a short time ago that a new art which had never before existed was invented..."--Fra Giordano (1306) "We are as dwarfs mounted on the shoulders of giants, so that although we perceived many more things than they, it is not because our vision is more piercing or our stature higher, but because we are carried and elevated higher thanks to their gigantic size."--Bernard of Chartres (c.1115)
