Enel Green Power, in partnership with 40south Energy, a small company based in Pisa, will supply 25% of the electricity destined for the Gorgona prison through the futuristic R115 prototype, which produces renewable energy by oscillating between the waves, generating a net saving of 20% on the prison bill.
The model has a power of 110 kW and is being worked on at 40south Energy, a small Italian company led by Michele Grassi, born in Pisa in 1970, who explains how it works as follows: "All the structures from which the appliance is made (four of 20 meters connected to each other by two other thirty-long tubes) move in different ways, because they are placed at different depths and this causes the action of the wave to be very different: the energy is extracted from these relative movements and is brought to the ground by a cable".
Enel Green Power is the first official purchaser of this project that began in 2007, a purchase that could lead to a profitable partnership for both companies in the future. For the launch of R115, only the green light is awaited from the superintendency, after which, we are talking about next spring, the apparatus will be able to leave from Castiglioncello for the island of Gorgona.
