A lfooded gravel pit near the port of Bremerhaven in northern Germany provided the test site for the launch of the 1:10-scale Nezzy2 prototype. At full size, it will be more than 350 metres wide and 200 metres tall, but even at this scale, peaking at around 18 metres above the water level, it has the appearance of a“real thing”;there are striking details in place, radically different from current industry practice. These include the self-aligning downwind layout with two closely interspaced counter-rotating rotors;the droplet-shaped towers in V-formation with guy-cables interlinking the towers to provide the tower-foundation interfaces;and only the three bright yellow buoyancy elements of the semi-sub platform protruding from the surface.
