   The underwater 'kites' generating electricity as they move   
      
   A pair of sleek, winged machines are "flying" - or at least swimming -   
   beneath the dark waters of the Faroe Islands in the North Atlantic.   
      
   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.
