Waterwheel Power

The water wheel is an ancient device that uses flowing or falling water to create power by means of a set of paddles mounted around a central wheel or axle. The force of the water moves the paddles, blades or buckets, and the consequent rotation of the wheel is transmitted to machinery via the shaft of the wheel. The first reference to its use dates back to about 400 B.C. The waterwheels were used for crop irrigation, grinding grains, supply drinking experts water to villages and later to drive sawmills, pumps, forge bellows, tilt-hammers, trip hammers, and to power textile mills.

Types of waterwheels

Looking for the right design and production of your waterwheel?
There are three basic types of waterwheels, each with its own advantages and disadvantages. Each type has been in use since at least Roman times.
The three types of waterwheels are the: (1) horizontal waterwheel, (2) the undershot vertical waterwheel, and the (3) overshot vertical waterwheel. For simplicity they are simply known as the horizontal, undershot, and overshot wheels. Greenspark has been designing, developing and manufacturing water-wheels in Africa since 2007.

Energy need calculation

How do I calculate the energy in my river stream and what else do I need to think of?
Energy is calculated through the flollowing standard formula:

E = H X g X Q X v

n the above mentioned equation, E=kW, h=head, g=gravity, Q=volume in m3/sec and v=velocity of the stream. The two vital factors to consider are the flow and the head of the stream or river. The flow is the volume of water which can be captured and re-directed to turn the turbine generator, and the head is the distance the water will fall on its way to the generator. The larger the flow - i.e. the more water there is, and the higher the head - i.e. the higher the distance the water falls - the more energy is available for conversion to electricity. Double the flow and double the power, double the head and double the power again.
