We Need A Battery Miracle - Professor Donald Sadoway Liquid Metal Battery To reduce the impact of climate change and meet the world’s energy demand, we need a reliable source of energy that’s cheap and emits no carbon. Many of the possibilities today involve intermittent energy sources such as wind and sun. The only way these can become primary sources of energy is if we develop inexpensive energy storage systems on a massive scale. Without this, renewable energy sources like wind turbines and solar cells will never approach the scale or affordability that is necessary. Over the last 50 years, the technology associated with generating wind and solar power has advanced, but not the technology to store it. I first met Professor Sadoway after going to MIT’s OpenCourseWare website and watching video lectures of his courses.

[INFOHIGHTECH] Grâce à l’avènement des composants électroniques élastiques, nous assistons actuellement à la mise au point des produits comme des tissus intelligents, des écrans pliables, et même une peau sensible à la pression pour les robots. Dans de nombreuses applications potentielles, cependant, l’utilité de composants électroniques serait limitée s’ils devaient encore être raccordés à une batterie rigide. En réponse à ce problème, une équipe de scientifiques a récemment créé une batterie extensible au lithium-ion. La recherche a été menée par Yonggang Huang de l’Université de Northwestern et John A.Rogers de l’Université de l’Illinois aux Etats-Unis. La batterie qu’ils ont créé, comprend 100 petits disques rigides d’électrodes disposées en une forme carrée, noyés dans une feuille d’élastomère de silicone extensible. Lorsque la feuille de silicone est étirée et que la distance entre les électrodes augmente, les fils de connexion se déroulent pour combler les écarts.

Ryden : une batterie double carbone moins chère et plus rapide à charger La société japonaise Power Japan Plus vient de dévoiler sa technologie de batterie Ryden où l’anode et la cathode sont faites de carbone, ce qui permet notamment d’éviter les surchauffes, d’améliorer les temps de charge et de limiter les variations thermiques pour plus de sécurité. Plus d’autonomie, une recharge plus rapide, pour un prix plus raisonnable : tel est ce qui manque aujourd’hui (entre autres) aux batteries utilisées dans les véhicules hybrides et électriques. Et c’est essentiellement ce sur quoi portent les recherches entreprises par les spécialistes du domaine, à l’image de Power Japan Plus qui touche peut-être du doigt la solution avec sa technologie Ryden. Dans cette batterie pour le moment cantonnée à l’état de prototype, l’anode et la cathode ne sont plus composées d’oxyde de métal ou de graphite mais de carbone. Les avantages à densité énergétique égale par rapport à la technologie d’accumulateurs lithium-ion telle qu’on la connaît aujourd’hui sont multiples.

A Plan to Power 100 Percent of the Planet with Renewables In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come. The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can. A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world’s energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030.

5 Terrible Things The Internet Does To Our Love Lives If you're the kind of person who's even vaguely aware of Valentine's Day, you're probably either Yelping a good restaurant to take your date to or searching Facebook for another single friend with whom to eat ice cream and cry over "Someone Like You." Technology affects your love life in ways that would've been unimaginable 30 years ago. We talked with Dan Slater, author of the new book Love in the Time of Algorithms, about how technology--and the web, in particular--is changing the way we meet, marry and love. Here are a few kernels of wisdom he shared. 1. 2. "It doesn't necessarily change what you want, but I think it changes your ability to pursue it, and it changes the way that you pursue it," Slater remarks. For people in relationships that aren't necessarily satisfactory -- the kind where someone's on the fence and maybe sticking around just to avoid being alone -- knowing that pool of singles lies just beyond a login page can be an impetus to make a break for it. 3. 4. 5.

Aquion Energy : une batterie « salée » pour stocker les énergies renouvelables Et si Jay Whitacre - fondateur d’Aquion Energy - aimait réfléchir en se préparant une bonne plâtrée de pâtes ? Un scénario vraisemblable quand on sait que l’eau et le sel figurent comme ingrédients majeurs de sa technologie innovante de stockage de l’énergie solaire et éolienne. Des pâtes, ce professeur en science des matériaux ne devrait néanmoins pas devoir en manger tous les jours dans les prochaines semaines. Concurrencer les autres technologies de stockage Alternative aux batteries lithium-ion, la pile d’Aquion Energy est donc une batterie sodium-ion.

Charging nickel-based batteries Learn how to maximize charge, minimize heat and reduce memory. Battery manufacturers recommend that new batteries be slow-charged for 16 to 24 hours before use. A slow charge brings all cells in a battery pack to an equal charge level. This is important because each cell within the nickel-cadmium battery may have self-discharged at its own rate. Furthermore, during long storage the electrolyte tends to gravitate to the bottom of the cell and the initial trickle charge helps redistribute the electrolyte to eliminate dry spots on the separator. Battery manufacturers do not fully format the batteries before shipment. Most rechargeable cells include a safety vent that releases excess pressure if incorrectly charged. Full-charge Detection by Temperature Full-charge detection of sealed nickel-based batteries is more complex than that of lead acid and lithium-ion. Chargers relying on temperature inflict harmful overcharges when a fully charged battery is removed and reinserted.

DE VENT ET D’EAU FRAÎCHE – Dans l’Atlantique, la première île 100 % énergies renouvelables Des éoliennes et un réservoir de la station électrique de Gorona, sur l'île d'El Hierro, aux Canaries. AFP PHOTO / DÉSIRÉE MARTIN Ce sera bientôt une première dans le champ des énergies renouvelables : l'île d'El Hierro, plus petite terre des Canaries espagnoles, est sur le point de satisfaire 100 % de ses besoins en électricité grâce à l'eau et au vent, rapporte le site L'ouverture en juin d'une nouvelle ferme de cinq éoliennes, qui fournira 11,5 mégawatts, viendra achever dans quelques mois sa transition et son indépendance énergétiques. Située au large du Maroc, l'île de 10 000 habitants comptera donc désormais sur ses deux principales ressources : le vent et la mer. « Quand le vent ne souffle pas, l'hydroélectricité prend le relais », note ThinkProgress. Et les ambitions écologiques de l'île ne s'arrêtent pas là, les autorités ayant prévu de reconvertir l'ensemble de ses 6 000 voitures à l'électricité. Signaler ce contenu comme inapproprié

z e a n - Investigación y Difusión de soluciones sustentables, energía renovable, arte, espiritualidad y expresión Rethinking ‘normal’ in technology: Q&A with Justin Hall-Tipping On stage at TED Global 2011 Justin Hall-Tipping set forth a bold agenda for funding innovation – one that makes room for radical changes and complete re-thinking of what’s possible. TED’s Ben Lillie tracked him down to follow up on the process of innovation, and his plans for the future. You made this point that we often get stuck on this idea of what normal is. Yes, I think it does. If you look back in history with the advent of the automobile, at that time, everybody was moving around either by walking or on horses. And I think your parallel to the solar cell is the same way. Is there a sense in that that the biggest challenge really is learning to live with change and understanding that change is a normal part of our life? Yes. Do you see a way of getting past that, of us getting to the point where we’re so used to change that we actually become quite good at it? Well I think over time we’re doing it. Having come out of that environment, that’s a little surprising of a statement.

A Salt and Paper Battery Researchers at Uppsala University in Sweden have made a flexible battery using two common, cheap ingredients: cellulose and salt. The lightweight, rechargeable battery uses thin pieces of paper–pressed mats of tangled cellulose fibers–for electrodes, while a salt solution acts as the electrolyte. The new battery should be cheap, easy to manufacture, and environmentally benign, says lead researcher Maria Stromme. She suggests that it might be used to power cheap medical diagnostics devices or sensors on packaging materials or embedded into fabric. The new battery uses a type of rechargeable thin-film design that many other researchers and companies have been working on for several years. Thin-film batteries typically use solid electrolytes instead of liquid or gel, and their electrodes are typically made of lithium combined with metals such as nickel, cobalt, or manganese. Thin-film batteries have other attractive features. The researchers are now working on optimizing the battery.

Iron-Chromium Flow Battery Aims to Replace Gas Plants The four round structures pictured above may look like grain silos but they're actually giant flow batteries. They're part of a demonstration plant going online this week, and proponents say it could represent the future of long-duration energy storage on the electric grid. Startup EnerVault will unveil tomorrow what it says is the largest iron-chromium flow battery ever made. Installed in Turlock, Calif., the four-hour, 250-kilowatt battery will be charged by a solar array and power an irrigation system. The project was funded by about US $5 million from Department of Energy through the stimulus program and the California Energy Commission. If this technology demonstration performs well, it will be a step towards much larger flow batteries that could replace natural gas plants or provide round-the-clock power from wind and solar farms. One of the advantages of a flow battery is that the energy capacity can be expanded by installing larger tanks of the active material.
