Roman Water Wheel London Museum
The Romans made and used many helpful devices, some of which are similar to those still in use. In the video below, you can see a Roman water wheel constructed by The Museum of London based on Roman artifacts found there.
A water wheel is a simple machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. The wheel is usually located near a stream or pond, which powers the mill.
A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim. Water wheels have been used for grinding grain into flour, power sawmills, and so forth.
