You need just a dip in the sea to feel the strength of the current, able to drag swimmers and boats without any difficulty. What if all this force could be used in the production of clean energy? That’s what the Carnegie Wave Energy did. In Garden Island, Australia, where is located the biggest Australian naval base, it was installed Perth Project, an initiative that uses the ocean waves to generate electricity and drinking water.
Attached to the seabed are buoys with about 20 meters in diameter that make up the so-called CETO 6. Moving according to ocean currents, buoys triggers the pumps, leading to water at very high pressure into the ground unit, by operating the turbines and generators and producing energy. The water pressure is also used to move desalination units that make the water in the sea for own consumption.
For now, all the energy produced by the project is used by the Australian naval base. However, the company plans to in 2016 to build an even bigger system, which perhaps can also feed residences in the area. This is not the first project that generates energy from sea waves, but it is the first one that does this with the submerged buoys, keeping intact landscape and avoiding possible damage from storms to buoys.
The development of systems like this ensure clean energy production and provide, theoretically, an unlimited supply of drinking water.
