and adrienne murray has been to the remote faroe islands, which are between scotland and norway, to see what they're doing to help harness renewable energy. 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 seabed, it will be

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 seabed, 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. it's sort of like kitesurfing, but underwater. so we tether it off to the sea floor, foundation on the sea floor, and then it flies in a figure of eight. as underwater currents flow by, the kite's wings generate a hydrodynamic lift force, spinning the turbine and generating electricity. this design�*s very different to other types of tidal technology. so what's the advantage of a design like this one? we can install and operate and produce power in low flow currents with lightweight machines. although it looks big to the eye, this is actually a very small tidal turbine. we've designed the system

The Engineer - NPL tests new methods to dispose of unexploded ordnance on seabed

Disposing of unexploded ordnance on the seabed could be less harmful to marine life after successful tests by the National Physical Laboratory of new methods developed by UK industry.

the algaray is designed to go across the surface of the water and take the sargassum into its cavity, much like it's doing with these ducks here. once it's full, it dives down to 200m, at which point the water pressure crushes the air bladders that keep it afloat and the sargassum sinks down to the seabed. there it's locked away for many hundreds, if not thousands, of years. the first version of the algaray was attached to a remote—controlled catamaran, whereas the final version is going to be a 10m—long submersible powered by green energy. bagpipes skirl. the whole thing is going to be covered in solar panels... 0h, 0k. ..so there'll be quite
