rugged and remote, the faroe islands are an isolated archipelago found in the north atlantic. powerful currents flow around its 18 islands, and in this sea channel called the vestmannasund, mechanical creatures lurk beneath the water's surface, called dragons. designed by swedish marine energy firm minesto, it's among a wave of new technology that hopes to revolutionise tidal power. this huge yellow thing behind me is a tidal kite. it looks a bit like a glider because it's designed to fly through the water, and once it's installed on the sea bed, it will be generating electricity using the current that flows through this stretch of water. weighing 28 tonnes and with a 12—metre wingspan, the newest dragon can deliver 1.2 megawatts of power.
