Energy saving

Wave energy


When we talk about renewable energies our mind imagines a wind farm, a photovoltaic system and at most one geothermal power plant, we hardly focus attention on wavy way and the sea currents, yet this is one energy resource of great importance for the planet. L'wave energy manages to exploit the kinetic energy of the waves for the production of electric energy with a system called cimoelectric.

When we talk about wave energy there are many classification that can be done, some concern the position of the implants, so we have devices offshore, offshore, devices shoreline, coast line and devices near to shore, near the coast. The choice of positioning depends on the refraction of the waves or on the identification of the so-called Hot Spots, specific points in which thepower.

Obviously, a "shoreline" plant will have very low maintenance costs but on the other hand, the amount of energy that can be obtained is much lower than that generated by a device offshore. The ideal would be to identify the Hot Spots energy lines along the coast so as to make the most ofwave energy and at the same time reduce installation and maintenance costs.

The devices they derive electricity from wavy way can also be classified according to the electrical generation mechanism, we have so oscillating water columns (OSCILLANTING WATER COLUMNS), energy converters consisting of an air chamber in which the water level rises and falls with the waves of the sea. The waves vary the pressure in the air chamber which generally action one turbine.

The so-called "Water jump " where a channel takes on a progressively decreasing width so that the passage of water through hydro turbines, similar to those used for hydroelectric plants with limited water jumps, they allow the generation of electricity. There are "Wave systems"Where a flexible air pocket that integrates a turbogenerator, is anchored to a buoy and, thanks to the wave motion, the bag inflates and deflates by activating the turbogenerator. Other devices exploit systems based on wave amplifies or the principle of Archimedes' thrust, and, even today, several prototypes are being tested that exploit new mechanisms.

Among the various technologies already widespread in the energy field, we point out the Pelamis, an energy converter manufactured by the Scottish "Ocean Power Delivery Ltd". It is a floating device which, installed in the open sea, is able to operate mechanical pistons which will in turn activate electric generators.
