Centrale osmotique : la Norvège se lance dans une nouvelle énergie renouvelable. C’est à Tofte, à 60 km au Sud d’Oslo, que la compagnie publique Statkraft, l’un des plus importants producteurs d’électricité et d’énergies renouvelables d’Europe, a choisi d’installer un prototype de centrale d’un nouveau genre : celle-ci utilise en effet l’énergie osmotique pour produire du courant.
Silencieuse, non polluante et renouvelable, cette technologie exploite la réaction induite par la rencontre de l’eau douce et de l’eau salée. Laissez un commentaire : Votre commentaire (min. 40 caractères) Ce phénomène, appelé osmose, libère une grande quantité d’énergie capable de faire fonctionner une turbine génératrice d’électricité. Concrètement, la centrale de Statkraft fait circuler dans deux réservoirs séparés par une membrane (fine pellicule qui laisse passer l’eau tout en retenant le sel) l’eau salée de la mer et l’eau douce d’un fleuve. Un potentiel considérable ? Pour l’instant, le prototype est à l’essai et ne fournira que quelques centaines de watts. Site de Statkraft.
Wastewater Treatment Plant to Produce Electricity From Fuel Cells. Just yesterday, I posted an overview of various waste-to-energy initiatives as part of our series on biofuels.
Today, I am here to tell you about a new development that extends this concept into new territory—the use of biomass to generate even cleaner electricity, directly through the use of a fuel cell. The idea of capturing biogas at wastewater facilities and using it to provide power is not new. For many years, plants have been using anaerobic digestion technology to produce biogas which was then burned to produce power in conventional gas turbines, while reducing the quantity of residual waste at the same time. In California, the Inland Empire Utilities Agency (IEUA) has been using digester gas to provide power to their plant for some time. However in the face of increasingly stringent air quality regulations for power generation, they decided to move up to a cleaner solution. Stanford scientists use 'wired microbes' to generate electricity from sewage. Engineers at Stanford have devised a new way to generate electricity from sewage, using naturally occurring "wired microbes" as mini power plants, producing electricity as they digest plant and animal waste.
In a paper published today in the Proceedings of the National Academy of Sciences, co-authors Yi Cui, a materials scientist, Craig Criddle, an environmental engineer, and Xing Xie, an interdisciplinary researcher, call their invention a microbial battery. They hope it will be used in places such as sewage treatment plants, or to break down organic pollutants in the "dead zones" of lakes and coastal waters where fertilizer runoff and other organic waste can deplete oxygen levels and suffocate marine life. At the moment, however, their laboratory prototype is about the size of a D-cell battery and looks like a chemistry experiment, with two electrodes, one positive, the other negative, plunged into a bottle of wastewater.
Of course, there is far less energy potential in wastewater. This Microbial Battery Makes Power And Water From Poop And Pollution. The idea of sewage-powered devices is not new.
In fact, it’s existed for more than a century. But finding a particularly efficient (and cost-effective) version of microbial fuel cell technology has been an ongoing challenge for engineers. A new “microbial battery,” however, looks like a breakthrough on the efficiency side of the equation. Researchers at Stanford University say they’ve developed a battery that can convert some 30% of the energy of dissolved organic matter in wastewater into electricity, the same proportion of energy that solar cells can harvest from sunlight.

Posted on Tuesday, November 6, 2012 · 168 Comments Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls.
The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15). 1 Liter of urine gives you 6 hours of electricity. The system works like this: Urine is put into an electrolytic cell, which separates out the hydrogen. Could A Sustainable Source of Energy Be Right Beneath Our Feet? The potential to generate energy is hidden in many places, from skyscrapers to ski-slopes.
But new research is showing that a potent source of energy is hiding right beneath our noses, or feet to be more specific. Some of the first thinking on the subject came from London-based architecture consultancy, The Facility. The idea began over a decade ago when the group came up with a method of dampening the noisy rattle of parts of London’s aging railways, while harnessing the energy that created the noise to generate electricity. Could a captive tornado power an entire city? You have to wonder what focusing that diffuse heat energy at one spot in the atmosphere would do to the local weather.
Warm air plus cool air don't always play nice with each other. Tesla Technology: 5 Bladeless Turbines About to Revolutionize Energy Production. “Every home in America can run on wind energy.
In fact these units can be installed on existing power poles in rural areas, to catch the wind and send its energy back to the plant.”- Raymond Green, Inventor In 1913, Inventor Nikola Tesla patented a bladeless steam turbine that he claimed was the most efficient and the most simple rotary engine ever designed.
Due to a lack of high-quality materials, Tesla was never able to properly build his engine. Planet Power: Chemical Reaction Makes Clean Electricity. No matter how energy-efficient your appliances are, there is always at least a little guilt associated with using electricity for people who are environmentally conscious.
Somewhere down the line, the chances are that the electricity powering those appliances came from a planet-harming source. This interesting concept product from designer Jun Hyuck Choi, Jooyeon Kim and Sungi Kim would take away the guilt and provide clean power for up to three devices at a time. The Eco Power Strip works on the concept of electrolysis: two liquids combine to create electricity.

Shimizu, a Japanese architectural and engineering firm, has a solution for the climate crisis: Simply build a band of solar panels 400 kilometers (249 miles) wide (pdf) running all the way around the Moon’s 11,000-kilometer (6,835 mile) equator and beam the carbon-free energy back to Earth in the form of microwaves, which are converted into electricity at ground stations.
That means mining construction materials on the Moon and setting up factories to make the solar panels. “Robots will perform various tasks on the lunar surface, including ground leveling and excavation of hard bottom strata,” according to Shimizu, which is known for a series of far-fetched “dream projects” including pyramid cities and a space hotel. The company proposes to start building the Luna Ring in 2035. “Machines and equipment from the Earth will be assembled in space and landed on the lunar surface for installation,” says the proposal. Electricité gratuite. Student Creates Electromagnetic Harvester That Gathers Free Electricity From Thin Air. A German student has built an electromagnetic harvester that recharges an AA battery by soaking up ambient, environmental radiation. These harvesters can gather free electricity from just about anything, including overhead power lines, coffee machines, refrigerators, or even the emissions from your WiFi router or smartphone.
This might sound a bit like hocus-pocus pseudoscience, but the underlying science is actually surprisingly sound. We are, after all, just talking about wireless power transfer — just like the smartphones that are starting to ship with wireless charging tech, and the accompanying charging pads. Dennis Siegel, of the University of Arts Bremen, does away with the charging pad, but the underlying tech is fundamentally the same. In essence, every electrical device gives off electromagnetic radiation — and if that radiation passes across a coil of wire, an electrical current is produced.

Windfarms do not cause long-term damage to bird populations, study finds. A major new study has quashed fears that onshore windfarms are causing long-term damage to bird populations, but found new evidence that some species are harmed when windfarms are built. The study by conservationists into the impacts on 10 of the key species of British upland bird, including several suffering serious population declines, concluded that a large majority of species can co-exist or thrive with windfarms once they are operating.
But the study, the largest carried out in the UK into the impact of onshore windfarms on bird life, also found strong evidence that some species suffered serious harm while windfarms are being built. "It shows that there can be serious species-level impacts in the construction phase, so construction in the right place is absolutely key. Wind power. DIY Residential Wind Generators.
