ocean waves as the renewable energy resource

The team of researchers at the University of California Berkeley  has discovered how to produce the cheap electricity and drinking water for coastal communities in California. They overlook on the possibility of the power from ocean waves by deploy energy from the regular movement of large amounts of sea water.

This kind of line of waves breaking along a coastline gives a steady stream of energy so the matter is water waves goes up and down, a motion that which is quite difficult to convert into a force pushing only one way like a flowing river or  blowing wind.They help this by design and underwater device that they say it can be useful to both of solving the problem and have a dual application.

Lehmann, one of the researchers said that their device has the advantage which they do not directly convert into electricity but they can decide themselves if they want to produce fresh water or electricity.

The great device looks like a carpet which rises and falls with waves, so it creates hydraulic pressure, pumping seawater towards the shore.

The device can pressurize water to be used to run turbines, generating electricity. Moreover, it can be pushed through special membranes which extract the salt to create fresh water for eco-system lives.

With this fantastic device can provide 15 percent of the global energy demand if the larger versions of the wave carpet is used and that means could generate the power for small coastal communities. That is very very pleased.

Without possible impact on coastal ecosystems, they said that this carpet can be optimized or deployed in so-called “dead zones” where there is not enough oxygen for marine life to thrive.

The American home along entire coastal towns can use power in low cost because only one-square meter of the wave carpet can share enough power for two general homes. Moreover, this method of using a carpet on the seabed in those locations is great safe to the environment.
