Innovations & Ecologie Découvrons cette fois ci un autre beau domaine de créativité qui est d’actualité, l’éco-innovation. Nous relevons avec enthousiasme les défis écologiques avec ingéniosité. Les enjeux sont de taille: la sauvegarde de nos forêts, éliminer la pollution marine, atmosphérique, la gestion de nos déchets, l’utilisation intelligente des ressources d’énergies disponibles. L’Homme prend conscience des effets néfastes qu’il peut avoir sur son environnement et renverser la vapeur ne pourra que nous faire du bien! Mes mots clés tendances dans ce domaine: #Upcycling #BioFuel #EcoDesign #Bionique L’efficacité des technologies augmente rapidement et on innove donc dans leur miniaturisation pour les intégrer dans les objets autour de nous. Le nouveau plastique AirCarbon L’invention de la société Newlight Technologies consiste à fabriquer de la matière plastique à partir de l’air pollué de carbone.

Home Qui est Boyan Slat, le sauveur des océans ? - - Cartridgeworld Magazine Ce jeune homme sauvera-t-il nos océans ? Boyan Slat, étudiant néerlandais de 19 ans, a un projet fou : débarrasser nos océans des millions de tonnes de plastiques qui l’envahissent, et forment aujourd’hui ce qu’on appelle les 7e et 8e continents. Son projet « The Ocean Cleanup » mobilise déjà une cinquantaine d’ingénieurs et soulève bien des espoirs du côté des amoureux de la planète… Boyan Slat, un jeune génie hyperactif Il a seulement 19 ans et il est déjà à la tête d’un projet très important, qui mobilise une cinquantaine d’ingénieurs. Son idée de génie : utiliser les forces naturelles des océans pour récupérer les 7,25 millions de tonnes de plastique qui les polluent. Des vaisseaux de nettoyage en forme de raie © Erwin Zwart Boyan Slat a développé « The Ocean Cleanup » en guise de projet de fin d’études pour sa dernière année de lycée, et n’a eu aucun problème pour défendre son idée lors de la conférence TEDx qui a eu lieu en octobre 2012 à Delft aux Pays-Bas.

CompoSt'ory Formation Kite power getting off the ground in Germany Despite offering numerous advantages over its rotating brethren, most notably the ability to reach the high-speed winds found at higher altitudes, kite-based energy systems are yet to really get off the ground in a meaningful way. But things are looking up. Earlier this year, NASA revealed it is investigating ways to improve the aerodynamics and autonomous flight control of kites for power generation applications, and now Berlin-based wind energy developer NTS GmbH has teamed with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) to make their own kite energy system concept a reality. The team’s “kite power station” would see kites attached to cables measuring around 700 meters (2,297 ft) long, which would allow the kites to fly at heights of 300 to 500 meters (984 to 1,640 ft). “The energy yield of a kite far exceeds that of a wind turbine, whose rotor tips turn at a maximum height of 200 meters.

/about-us.html You know about us because we're a small farm with a big name. We've shown that no-till vegetable production is not only possible, but can be highy productive and profitable. We've quadrupled our soil organic matter, without nutrient leaching, while nearly tripling the total microbial life in our soils. We've increased bird and native bee populations and diversity. We've increased native perennial plant diversity and density. Singing Frogs Farm continues to be a living experiment. As we, and leading soil scientists, learn more about the biology of the soil beneath our feet, our methods and farming systems here at Singing Frogs Farm are constantly changing and being improved upon. 1) Disturb the soil as little as possible, 2) Keep a diversity of living plants in the ground as often as possible, and 3) Keep the soil covered and protected as often as possible.
Graphene Batteries Offer 5-Second iPhone Charging Researchers at UCLA have discovered a way to make graphene batteries that charge super fast, are inexpensively produced, are non-toxic, and that blow current battery technology out of the water in terms of efficiency and performance. An iPhone powered by a graphene supercapacitor could charge in five-seconds. A MacBook powered by a graphene supercapacitor could charge 30-seconds. Electric cars powered by the technology could be charged as quickly as filling a car with a tank of gas. The new energy technology was developed by Richard Kaner, a member of the California NanoSystems Institute at UCLA where he is also a professor of chemistry and biochemistry. “To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. The micro-supercapacitors created by Kaner and El-Kady are highly bendable and twistable and will be ideal for future flexible displays, e-paper, and wearable electronics.
3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production | Autopia Engineer Jim Kor and his design for the Urbee 2. Photo: Sara Payne Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles. If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced. His creation is called the Urbee 2 and it could revolutionize parts manufacturing while creating a cottage industry of small-batch automakers intent on challenging the status quo. Urbee’s approach to maximum miles per gallon starts with lightweight construction – something that 3-D printing is particularly well suited for. Jim Kor is the engineering brains behind the Urbee. “We thought long and hard about doing a second one,” he says of the Urbee. Kor and his team built the three-wheel, two-passenger vehicle at RedEye, an on-demand 3-D printing facility. Photo: Sara Payne “We’re calling it race car safety,” Kor says.
Energy-producing shell covered with hairs that can extract wind energy Belatchew Architects presents a visionary idea called STRAWSCRAPER, the first project to come out of their business called Belatchew Labs. STRAWSCRAPER is an extension of the south tower on Södermalm in Stockholm with a new energy-producing shell covered with hairs that can extract wind energy. What was originally meant to be 40 storeys became only 26. The South Tower on Södermalm in central Stockholm was completed in 1997, but the architect Henning Larsen had then dropped out of the mission after having lost control over the design of the tower. Belatchew Architects want to give South tower its original proportions and at the same time explore new technologies to create the future of urban wind farming. Furthermore, an additional aspect is revealed when the constant movement of the straws creates an undulating landscape on the facades.
New Invention Makes Ocean Water Drinkable Susanne Posel Occupy Corporatism July 2, 2013 Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater. Incredibly this technique requires little more than a store-bought battery. Called electrochemically mediated seawater desalination (EMSD) this technique has improved upon the current water desalination method. Richard Cooks, chemistry professor at the University of Austin said : “The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.” Cooks continued: “Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. Kyle Krust, lead author of the study said: “We’ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.
Power plant claims to produce hydrogen by splitting water with sunlight The plant would use an array of mirrors to focus sunlight onto a huge towerThe tower heats up to 1,350 °C - enough to liberate hydrogen from steamScientists describe the process as the Holy Grail of a hydrogen economy By Ellie Zolfagharifard Published: 18:07 GMT, 1 August 2013 | Updated: 11:31 GMT, 14 November 2013 Scientists believe they have achieved the ‘holy grail’ of the green economy by designing a hydrogen production plant that can split water with sunlight. The University of Colorado at Boulder envisages an array of mirrors that would focus sunlight onto a central tower several hundred feet tall. The tower would heat up to around 1,350 °C - enough to liberate hydrogen from steam with the help of a metal oxide compound. A concept design of a hydrogen production plant that could fuel a sustainable green economy with sunlight and water. An array of mirrors focuses sunlight onto a central tower several hundred feet tall. This frees up hydrogen molecules for collection as hydrogen gas.
