The underwater ‘kites’ generating electricity as they move ….
A BBC Business article about one of the technologies MINESTO are planning to use off Anglesey
Known as “sea dragons” or “tidal kites”, they look like aircraft, but these are in fact high-tech tidal turbines, generating electricity from the power of the ocean.
The two kites – with a five-metre (16ft) wingspan – move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.
Their movement is generated by the lift exerted by the water flow – just as a plane flies by the force of air flowing over its wings.
Minesto is planning to test and install these off Anglesey
