Water wheels have been around since the times of ancient Greece and continue to provide sources of alternative energy even today.
Mostly water-powered wheels were designed to provide mechanical energy for some specific task. The
turbine owes its origin to this humble beginning.
Greek ideas were advanced by the Romans who employed the idea further. Sawmills were developed.
In the middle ages and later water power became a major source of leveraged power technology. The units became more and more common.
Even to the beginnings of the industrial revolution water-powered wheels were used to supply mechanical power for factories, forges and similar settings.
Even in ancient China these devices were employed to generate power to drive bellows for steel manufacture.

Sawmills could run their huge blades and save physical energy from people. Large logs could be sawn quickly and accurately.
A water-wheel was employed for grinding various grains from earliest times.
The designs for driving water-based wheels are many and varied. They can be dipped into streams to allow the current to turn blades in them.
Or flows can be directed from a stream onto a wheel. There are multiple designs for this from letting water flow onto the near or far side of the wheel, to the angle of the blades which allows for various levels of filling of the blades.
Blades were at times replaced by buckets. This allowed for greater power to be developed.
In feeding water from a race, rather than directly from the stream or river, the flows could be manipulated or stored above the race to be used when needed.
For people with access to freely flowing water there is still a place for such technology today.
Just as with those units designed to work with wind, these can do active work or even generate electricity with an alternator set-up. Power can be stored in batteries or directly used for low draw requirements.
The turbines that drive current hydroelectric installations were an improvement in the design of a water-powered wheel to make it even more efficient, by the way the water movement in the apparatus was virtually completely utilised.
Even with their ancient history water wheels offer benefits today for those seeking alternative energy supplies.
