Triton – The Affordable and Robust Wave Power Harvester

Mila Luleva — Mon, 22 Feb 2016 18:18:09 +0000

Triton system is the latest very promising development in the field of wave energy. Wave power, also often referred to as tidal power, has been an ‘on’ and ‘off’ topic over the last decade. Many technologies have emerged over the years, many of them have failed (mainly because of underestimating the power of the oceans), and of […]

World’s First Artificial Tidal Lagoons to Get Built in UK

Mila Luleva — Wed, 04 Mar 2015 18:22:21 +0000

The UK might soon be the first in the world to have artificial tidal lagoons, which will generate clean power by harnessing energy from tides. The billion euro project, called Tidal Lagoon Swansea Bay, was announced earlier this week, and it aims to build six tidal lagoons in Wales, Somerset and Cumbria, where tides will be […]

Does Ocean Energy Mean Wave Power or Tide Power?

Benji Jerew — Thu, 11 Jul 2013 18:03:10 +0000

Another form of hydroelectricity being investigated involves the movement of the ocean. Here, consistency could mean the difference between wave power or tide power. Like the wind that drives them, ocean waves are intermittent. Thus, any wave power generators that have been developed suffer from the same problems that on- and off-shore wind power generators […]

Tidal Power May Become Major United Kingdom Energy Source

Leigh Hutchens — Wed, 16 Jan 2013 21:12:56 +0000

According to a report in the journal Philosophical Transactions of the Royal Society A, estuary barges and tidal streams might be able to provide over 20% of the United Kingdom’s electricity. The report finds the predictable nature of tidal patterns makes them ideal as a renewable energy source. However, finding ways to harness tidal power […]

Deep Green’s Tidal Energy Technology a Game Changer for Sustainable Energy

Leigh Hutchens — Tue, 27 Nov 2012 06:26:13 +0000

The Swedish company Minesto has secured rights from The Crown Estate to perform tests off the coast of Northern Ireland to determine if they can generate electricity from low velocity currents and ocean tides. Minesto, no stranger to marine power, has already developed technology to produce electricity from low velocity tidal and ocean currents. The […]

Nautricity's Device to Make Tidal Energy More Affordable

Mike Sandru — Mon, 02 May 2011 17:09:00 +0000

Tides are capable of producing electricity and are more predictable than wind or solar power. Just like wind turbines in the sea, they need to stand on very firm ground. All of that is known from the 60's, but what researchers didn't know was how to make that cost-effective, the main reason why development lagged behind.

India Plans to Build Its First Commercial Tidal Power Plant

Mike Sandru — Mon, 17 Jan 2011 11:05:02 +0000

Atlantis Resources Co, a London-based marine energy developer, had the idea of building a tidal power plant with an initial capacity of 50 MW. Gujarat, an Indian state, has already made some plans for the installation of the first commercial tidal power plant in India. The project will be organized in partnership with Guajar Corporation Limited.

Everything We do Emits Heat – Bad in the Long Run, or Not?

Ovidiu Sandru — Mon, 01 Dec 2008 08:06:05 +0000

I don't know what to believe anymore, sometimes. We seem to run of global warming, we reduce pollution and try to "green" ourselves through electric cars, solar cells and wind mills, yet scientists (as if all this global warming mess is all on their football field) say there will still be global warming due to the heat our machines, as a whole, emit in the ecosystem.
