A wave-energy machine The diagram illustrates a machine for generating electricity by waves and where it can be placed. What stands out from this diagram is that there are two chambers and turbines, with a chamber above the other. The process will start when water go into low chamber, and air rush into the other chamber. Then the water in low chamber rise up and push up the air in the surface of water to turn a turbine, and then when the water drop down, so the air flow into the space the chambers to turn turbine. Therefore, we can generate electricity from two turbine which make we have more profitable than only a turbine. Seeing the next diagram is that there are two places can install the machine namely near or far the coast. Indeed, we install the machine near the coast that will get you less money but it cannot create lots of electricity because of weak waves. Alternatively, the machine can be placed in deeper water where waves tend to be bigger, and so more electricity.
