A 200-kilowatt demonstration version of Wave Swell Energy's fascinating "blowhole" power generator has been deployed at Grassy Harbour on King Island, off the Australian island state of Tasmania, and ...

(Nanowerk Spotlight) In estuaries, where rivers flow into the sea, enormous free-energy dissipation takes place when fresh river water mixes with salty sea water. The release of Gibbs free energy from ...

July 6, 2007 Researchers at the University of Southampton have developed a kinetic energy generator which derives electrical energy from the vibrations and movements that occur within its environment.

A home generator that offers free electricity for 20 years arrives on the energy market. Wind energy is reaching unsuspected limits. It is based on obtaining energy from the speed and force of the ...

Wave power—energy harvested from ocean currents—is likely to be the next big thing in renewable energy generation, so researchers are spending quite a bit of time on new technologies to take advantage ...

Dutch inventor Janjaap Ruijssenaars has built a gravity energy generator that harnesses the force of gravity to produce a new kind of renewable energy. Matthew Stock reports.

The search is for new ways to harness renewable resources to supply our rising energy needs. The key question, however, is why ocean and sea waves haven't been used in carbon emission reduction ...

Though research on moisture-electric generators, which create energy from ambient humidity, exists, the tech isn't ready for real-world use yet.

For several years, CalWave has been developing its xWave clean power technology. Now, the company announces the completion of a long-term open-ocean test off the coast of San Diego, during which the ...

When you consider the solar panel, you likely conjure images of vast open fields, covered in rows upon rows of solar cells, harvesting precious energy from the sun. But what if we could shift that ...
