GEMSTAR Oceans Kite

The GEM system can be easily towed to the installation site and thanks to the self-towing winch can be positioned at predetermined depth (standard depth: 13 m). In absence of current, the GEM will float on or near the surface. When water current is flowing, the device will assume a positon mid-way in the water column. For maintenance, the GEM can be easily brought to the surface simply releasing the tension of the mooring line. The main characteristic of the GEM, however, is its passive capacity of aligning itself along the current direction and this reminds the typical behavior of a kite from which the name Ocean's Kite. In case of need, however, it is possible to control this alignment through the aid of a controlled designed system which uses the turbines as propellers. Total weight: 10700 kg Buoyancy force: 5200 kg Depth (range): 15 m to 9.8 m (without current) Nominal power: 100 kW with a tidal current of 2.6 m/s Three-blades 3 m diameter rotor Innovating blade section profiles Carbon blades - Fiberglass diffuser Rated rotation speed: 65 rpm Rotor Efficiency: 0.8 Expected average yearly production with 2.5 m/s maximum speed site: 300 MWh
