Thermoelectric generator harvests renewable energy from the cold of space As effective as solar panels are, one of their major downsides is that they only produce power during the day, so excess ...

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. Florida Teen Tara Ashley ...

(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 ...

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 ...

In a radical move, researchers have made the most significant stride yet toward unlocking almost inexhaustible sources of green power. This is from OpenStar Technologies, a New Zealand company that ...

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 ...

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.

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 ...
