One of the most eye-catching designs to harness tidal energy to emerge in recent years is a giant metal ‘kite’ which swims underwater against the current, turning its rotor and generating electricity. Power is then sent to the grid via a subsea cable which also acts as the kite’s tether.
The biggest of these kites ever built, known as Dragon 12, is about to be installed off the Faroe Islands. With a wingspan of (you guessed it) 12 metres, the Dragon is expected to generate 1.2MW of clean electricity once operational — enough to power around 1,000 homes. The kite is now being shipped from Sweden to the Faroe Islands for installation.
