TidalStream system could provide Britain with a large portion of its energy needs

According to respected ocean engineers, the TidalStream system built to harness tidal waters for power would produce somewhere between 20 to 40 percent of Britain's energy requirements, a production capacity equivalent to a large nuclear plant.
Scientists have said that underwater generators based on wind energy could be used for harnessing enough energy to supply residents of the UK with power equivalent to a nuclear power station.
Researchers have said that the TidalStream system built to harness the power of deep, fast-flowing tidal waters would produce somewhere between 20 to 40 percent of Britain's energy requirements, and provide the power capacity of a 1200-megawatt nuclear plant, enough energy for over a million households.
"If the U.K. were able to tap all of the tidal energy available, it would probably produce somewhere between 20 and 40 percent of all its energy requirements.
Even extracting a fraction would produce a useful contribution," Discovery News quoted ocean engineer Julian Wolfram, soon-to-be appointed visiting professor at the University of Edinburgh as saying.
Being developed by John Armstrong, former technical director of the Wind Energy Group at Taylor Woodrow, and Mike Todman, former chief engineer at Rolls Royce Marine, the system involves installing and maintaining underwater turbines in rough seas and deep waters, technically very challenging and expensive.
The logistical needs of installing them require them to be secured to the seabed with large, stable foundations that prevent the strong currents from toppling over the structures.
