A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where ...
Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...
Marine Current Turbines (MCT) was a Bristol-based company that developed seabed mounted tidal-stream turbines. In June 2003, MCT installed the 300 kW Seaflow turbine in Lynmouth , Devon. [ 46 ] The larger 1.2 MW SeaGen turbine was installed in Strangford Lough in May 2008, and connected tot the Irish electricity grid in July.
At 6 MW, the SAE Renewables (SAE) MeyGen project in the Pentland Firth is the world's largest tidal stream project in 2024. The first turbine was installed in November 2016. [ 30 ] Three further turbines were installed by February 2017, [ 8 ] and the first phase entered commercial operation in April 2018. [ 31 ]
The first in-stream tidal current generator in North America (Race Rocks Tidal Power Demonstration Project) was installed at Race Rocks on southern Vancouver Island in September 2006. [ 34 ] [ 35 ] The Race Rocks project was shut down after operating for five years (2006–2011) because high operating costs produced electricity at a rate that ...

Two types of Tidal Stream Generators Evopod - A semi-submerged floating approach tested in Strangford Lough with SeaGen in the background.. A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from the ...
The Race Rocks Tidal Power Demonstration Project (official name: Pearson College - EnCana - Clean Current Tidal Power Demonstration Project at Race Rocks) was a joint project of the Lester B. Pearson College, EnCana Corporation and Clean Current Power Systems Incorporated to use tidal power at Race Rocks near Victoria, British Columbia in Canada.
