A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial ...

The wheels are the ‘undershot’ type, driven by water flowing underneath them and pushing the wheel's paddles. In terms of height, the tallest of the norias is 21 metres (69 ...

All the interior is of wood – ladders, bins for the meal, floor-boarding, square pillars, beams, narrow passages, fittings, shaft rising to the first floor and all. So ramshackle is the arrangement of the props and supports that it is a wonder that the whole edifice does not tumble about the miller's ears like a pack of cards.
Wood water wheels along riversides may be considered the first examples of "small hydro". [15] Up to the 17th century the efficiency of water wheels neared 70%. However, as the need for power generation increased small hydropower projects were phased out in favor of the large scale dams using newly designed turbines. [16]
The norias of Hama on the Orontes River in Syria ().. A noria (Arabic: ناعورة, nā‘ūra, plural نواعير nawāʿīr, from Syriac: ܢܥܘܪܐ, nā‘orā, lit. "growler") is a hydropowered scoop wheel used to lift water into a small aqueduct, either for the purpose of irrigation or to supply water to cities and villages.
The wheel was powered by water delivered from a dam upriver (no longer extant) via a wooden head race (also not extant, although it survived until 1951). This wheel provided power to lockmaking concerns until about 1940, when the factory was demolished. Of Connecticut's three surviving 19th-century water wheels it is the best preserved. [2]
