The world's largest tidal turbine, standing more than 5 stories tall, has been unveiled in Scotland before being installed in the waters off Orkney later this summer. The Atlantis Resources Corporation's AT-1000 turbine is 22.5 meters (73 feet) tall and has a rotor diameter of 18 meters (59 feet) and weighs 130 tonnes. It will produce 1 MW of power from a water velocity of 2.65 meters (8.7 feet) per second. This is considerably larger than the river turbines other locations have proposed.
"The giant turbine is expected to be environmentally benign due to a low rotation speed whilst in operation and will deliver predictable, sustainable power to the local Orkney grid." The turbine blades will only turn at a rate of 6 to 8 revolutions per minute.
The tidal turbine project is connected to a plan for a data center located in northern Scotland and intended to be powered entirely by tidal power. Tidal power offers a predicatable, reliable energy source. Water is 832 times as dense as air, making it possible to draw similar amounts of energy from a much smaller turbine unit. However, the harsh marine conditions that underwater equipment must face has made development of tidal energy a slower process.
