Richfield generates energy for electricity through tidal waves.

Earth is composed mainly of bodies of water---about 71 percent of the earth's

surface is water. Ninety-seven percent of that is found in the oceans. Because

the earth's surface is curved, the sun heats it unevenly. This causes winds to

blow across the water and generate waves. The sun and moon also exert their

gravitational pull on the earth, triggering wave-producing tides. Wave motion

energy can be harnessed and generated into electricity.

The methods we used to generate wave energy:

Firstly, a system of buoys rises and falls with the waves, causing an electric

generator to produce electricity that is propelled along a power cable to shore.

Secondly, a water column apparatus uses waves to fill and empty the column,

forcing the air inside to go up and down. This piston-like action rotates a

turbine which produces electricity.

Thirdly method involves a tapped-channel arrangement which directs waves

into a raised reservoir and generates hydroelectric power by allowing water to

flow from the reservoir.
