Abstract
New defense location is in the seabed transition zone between enormous offshore pulsing vertical waves energy and conversion into inshore horizontal currents energy. Artificial reef, articulated in staggered barriers of the turbines, compose a soft defense of the coasts that mimics the coral reef, especially for its location far from the storms. The barriers reduce the sea currents speed below the sea level with the consequent deposition of the suspended sand for natural nourishment. The patented vertical turbines are made up of helix fixed to a floating spinning top so as to be in indifferent equilibrium in water, for which they turn by the minimum currents. The electric energy is produced even at low number of laps, but long lasting and therefore with hours of production higher than the eolic and photovoltaic. The costs of these barriers are very advantageous compared to the actual coastal defenses, based on the nourishment and on the cliffs, because the direct electrical dispatching covers the cost of amortization, and specially the cost of the maintenance. The new defense, in order to prevent sea level rise due to climate change, also embank the coast flooding through the natural nourishment and re-growth of the marine grasslands, so as recovering hectares of the beaches, with great economic benefits. The reconversion of the usual nourishment and the cliffs by proposed energized reef recoveries the marine ecosystem, the landscape and promotes the sea depollution
