What happens if you run an electric motor backwards? In short, it stops being a motor and becomes a generator. Following this principle, researchers at the University of Southampton have built a new ...

Most current tidal stream generators are essentially wind turbines turned upside down and made to work underwater. They often include complex gearboxes and move the entire assembly to face the flow of ...

Proteus Marine Renewables (Bristol, U.K.) has successfully deployed its AR1100 tidal turbine in Japan’s Naru Strait, which will now generate 1.1 megawatts of clean energy, accelerating the ...

The City of Liverpool, England, has unveiled advanced proposals to build the world’s largest tidal power generator on the River Mersey. If it’s built, Mersey Tidal Power would become the largest tidal ...

Earlier this week, a company called Orbital Marine Power successfully launched its latest tidal turbine. Once it’s connected to the European Marine Energy Centre off the Orkney Islands, the two ...

The attraction of a tidal generator is that water has 800 times the density of air, so it contains 800 times the energy when in motion. That basic fact explains why tidal generators are attracting the ...

7 April 2008 – The UK government has gave permission for a prototype tidal stream generator which could power 70 000 homes. The prototype will be positioned off the south bank of the Humber at Upper ...

We've already heard about renewable energy systems that use aerial kites to generate electricity via the wind. Well, the Manta system is kind of similar, although it uses an underwater kite that ...

A Portland company hopes to have its 60-kilowatt underwater tidal generator in Cobscook Bay fully operational in August after conducting favorable beta tests, paving the way for a larger commercial ...

A day before world leaders meet at COP26 to discuss the importance of clean energy, scientists from across the UK say that harnessing the power of the ocean's tidal streams can provide a predictable ...
