GWave Power Generation Vessel
The working principle of the GWave Power Generation Vessel (PGV) consists of a floating sealed tube such that sea water doesn’t engage with any internal components. The tube is aligned with the incident waves, and as swell passes under it, the tube pitches fore and aft. Within the tube, there are large weights that roll on tracks. As the vessel pitches downward, the weights roll downhill, and then as the swing of the buoyancy pushes that end of the vessel back up, the weights are once again positioned to roll back downhill. Then the kinetic energy, by way of linear motion, is converted into electricity. The vessel is 72 m long, 22 m high, and weighs just under 13,000 tons. The GWave PGV was scheduled for testing at Wave Hub in the UK in 2018, but was postponed indefinitely.
