The way of exploiting wave energy with the SEWAT device is very simple but very effective and is inspired by the observation of the natural scenery offered by the breaking waves
When the wave breaks on the rocks, the water rises on the cliff and then falls uncontrollably.
So in nature there is the dissipation of wave energy which often involves the erosion of the coast.
With the proposed SEWAT device we want to control the fall of the water of the breaking waves with the aim of obtaining energy.
The proposed device is a collector that collects the energy that waves have received from the wind over an absorbent surface area of hundreds of square miles. Consequently, the energy density (understood as the energy obtainable per unit of occupied surface) is very high and allows to obtain high powers.
It should be noted that energy is not subtracted from other natural systems, because the captured energy would still be naturally dissipated.
The SEWAT project is currently in an experimental phase. Qualitative tests were carried out using a model in order to validate the concept (Technology Readiness Level - TRL3 experimental proof of concept). At present we are building an experimental prototype to be tested at sea in real conditions (TRL 7 system prototype demonstration in operational environment). It will be located in the sea next to a breakwater barrier in the Municipality of Torchiarolo (Brindisi).
The purpose of experimenting with the prototype is to test the productivity of the system and gain further knowledge for the development of the project
The very simple but ingenious idea concerns the production of large quantities of renewable energy, using the energy of small waves in a sustainable way. No risk, no dangerous implications and no CO2 production. The goal is to exploit energy from a source that has so far been considered marginal. The system consists of modular concrete tanks, placed in the sea, partly submerged, placed on the side of dams and breakwaters barrier exposed to the waves or in the distance, parallel to the coast, at a certain distance to protect the coast itself.
