It's a 35 metre long rail, part of a 100 kilowatt wave energy converter that in a few weeks, will be towed out to sea off the Tuscan coast and sunk. Each component of the machine is bouyant. The rails will be suspended by tethers about 25 metres above the Mediterranean sea-floor, allowing the upper section to move in rhythm with the sub-surface waves. Power is generated through the piston-like movement of the arms that connect the two sections. Sea tests will take place over three months.moreless
