Wind/Wave Power Not Infinite and Not Renewable, German Scientist Claims

Posted by Ovidiu Sandru in Wave power, Wind Power on April 1, 2011

Wind power had always been considered our salvation from peril, our last and most accessible “renewable” resource on this planet. Well, Axel Kleidon, a scientist at the Max Planck Institute for Biogeochemistry in Jena, Germany, has another theory: wind and wave power are not so renewable and infinite, after all.

Hydrostatic Turbines: a Concept That May Revolutionize How We Harvest Deep-Sea Waves

Posted by Ovidiu Sandru in Wave power on January 13, 2011

An interesting concept for producing energy has caught my eyes today, and I think it might even work. The devices that Phil Pauley conceived are called “Hydrostatic Turbines”, and operate at high water depths.

Tidal Turbines Could Harm the Ecosystems Hosting Them – Solutions Sought

Posted by Ovidiu Sandru in Wave power on December 16, 2010

There has recently been an interesting debate whether engineers should change the shape of tidal turbines because of the negative effects these would have on the environment, and, more specifically, the fish. Current tidal turbines’ blades are made using the pattern used in wind turbines.

Wing Waves: Harvesting Wave Power By Swinging Beneath The Surface

Posted by Ovidiu Sandru in Wave power on December 3, 2010

A wave power test plant has been deployed on Nov. 17 two miles offshore of Fort Pierce, Fla., and is now being tested by its designers, researchers from Florida Institute of Technology’s College of Engineering. The power plant has been named “Wing Waves,” and works by harvesting the elliptical motion of waves 30 to 60 feet deep, and converting it into electricity.

PowerBuoy-The United States' First Tidal Power Generator Connected To The Grid

Posted by Mihai Sandru in Wave power on September 29, 2010

Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.

Nova Energy's New Streamlined Tuna-Shaped Turbines Shaped To Be More Efficient

Posted by Mihai Sandru in Wave power on September 16, 2010

Kiyomi Suzuki, president of the Hyogo Prefecture firm Nova Energy Co., has come up with a new interesting project for the Seto Inland Sea that aims to produce huge amount of electricity from the energy of water currents, using streamlined turbines whose design resembles the tuna shape.

Wave Hub Become UK's First Offshore Wave Energy Site and World's Largest

Posted by Mihai Sandru in Wave power on September 8, 2010

Wave Hub is the name of one of the world’s biggest wave energy generation test site. It has been installed off Cornwall’s northern coast and is the UK’s first offshore wave energy site. Wave Hub will allow four wave energy generator systems to be evaluated simultaneously. The systems also have a total capacity of 20 MW.

Australia's Best Spots for Harvesting Wave Power Shown by New Study

Posted by Ovidiu Sandru in Wave power on August 18, 2010

The Australians have just evaluated their potential for producing wave-based energy, within an area stretching from Gerlandton in Western Australia to King Island in Tasmania, and found out that by only using 10% of this area’s potential they could meed 50 percent of the entire country’s need.

Power Generating River Turbines To Be Installed Under Famous Parisian Bridges

Posted by Ovidiu Sandru in Wave power on June 30, 2010

After having installed the heating systems of some of their buildings based on underground springs, and mini-windmills on buildings, the people of Paris will have yet another clean energy generation project right under their famous and historical bridges. They call them “hydroliennes”, or water turbines, powered by the river Seine (if you haven’t visited Paris, you should).

Oyster 2 – A New Wave Power Generator Producing More Electricity

Posted by Mihai Sandru in Wave power on May 22, 2010

Aquamarine Power, a wave energy developer, has recently unveiled a new wave power generator called Oyster 2, that is able to capture about 250% more electricity than its predecessor. The Oyster 2 measures about 85 feet long and 53 feet wide, being capable to produce 800 kilowatts of energy.

Aegir: Scotland's Largest Wave Power Project

Posted by Cristi in Wave power on December 27, 2009

Just recently, Scotland-based energy developer Pelamis has signed a joint-venture with the European energy giant Vattenfall, for the huge energy project off Scotland’s Shetland Islands. The costs of the project rise to almost $100 million.

Oyster – World's Largest Hydro-Electric Wave Energy Device Goes Online

Posted by Mihai Sandru in Wave power on December 9, 2009

Queen’s University Belfast, Aquamarine Power Ltd. and the Scottish government have recently launched the largest working hydro-electric wave energy device, taking an important step for global wave energy industry.

Researchers Use Wind Turbine Technique to Build Efficient Wave Powered Generators

Posted by Ovidiu Sandru in Wave power on November 23, 2009

Mankind has been adopting the working principles of natural phenomenons and animals since ages. Now, when it’s time to learn from fish to develop wave-powered generators, it’s also time to learn what others have learned from birds – and use them in the seas, to gather energy which they would later turn into electricity.

Swing Door WaveRoller Generates Up to 300KW of Energy in the Surge Zone

Posted by Cristi in Wave power on November 7, 2009

One of the simplest ideas of harvesting the ocean power was developed by Rauno Koivusaari, a fin diver who got inspired by exploring the depths of the seas and lots of shipwrecks.

Oceanlinx Prepares to Deploy 2.5MW Tidal Power System Near Sydney

Posted by Cristi in Wave power on October 26, 2009

Engineers are performing the last tests and measurements before the grid-connection off the coast of Port Kembla, near Sydney. The system will be generating about 2.5MW by harvesting air pressure that will turn a wind turbine.
