Imprimantes 3D | Le blog de Yannick Rumpala Suite des réflexions annoncées dans le billet précédent sur les imprimantes 3D. Je me permets ici de détourner et d’adapter le titre du deuxième chapitre du livre d’Elizabeth L. Eisenstein (The Printing Press As an Agent of Change, Cambridge, Cambridge University Press, 1979, dont on peut également trouver une version en français). Quelles capacités les imprimantes 3D donnent-elles ? Des développements technologiques qui peuvent renouveler les capacités de fabrication Ces machines attirent[1] parce qu’elles semblent dotées d’un ensemble de propriétés physiques relativement inédites, parce qu’elles proposent des modes relativement nouveaux de fabrication et qu’elles semblent donc capables de faire certaines choses qu’il semblait plus difficile de faire auparavant[2]. L’intérêt pour les imprimantes 3D s’est accru au fur et à mesure de l’amélioration apparente de la qualité de leurs réalisations et de la baisse de leur coût, qui devient accessible pour un budget individuel ou familial.

Potential drought resilience strategies for the Horn of Africa The Horn of Africa (HoA), which comprises of eight countries, has an estimated combined population of 210 million people and is one of the world’s most food-insecure and vulnerable regions on the planet, with the majority of the inhabitant’s pastoralists and agro-pastoralists, living on marginalized lands. Poverty, rapid population growth and conflicts are also common in the region. Factor in recurrent droughts which have induced high rates of crop failures, diminished potential livestock grazing lands and result in loss of lives and livelihoods, makes this region of the world one of the most challenging and difficult places to live. In 2011, the region faced the worst drought in decades that decimated crops and livestock, and left over 12 million people, mainly the pastoralist communities, in distress across the affected region. Prior to the devastating drought, a Regional Study on Sustainable Livestock Development in the HoA was commissioned by the Africa Development Bank (AfDB).

Re.Verso: Wool Waste Fibers Recycled Into New Material If wool is on your shopping list for sustainable materials to source for your next collection, then you should check out Re.Verso. This new textile platform puts a more eco-friendly spin on this already versatile fiber. Using a 100% transparent method of production, pre-consumer waste fabric and fibers (mostly wool) are collected and recycled into an entirely new material. Produced in Italy, Re.Verso fabric is a multi-step collaboration between three mills: Green Line, Nuova Fratelli Boretti and Lanifico Stelloni. The raw material to be recycled is sourced from all over Italy, as well as a few other European countries, courtesy of Green Line. Once the waste fiber is collected, this raw material is prepped for spinning at Nuova Fratelli Boretti. The result is beautiful woolen textiles that are of the same quality as fabrics that are brand new- but with a much smaller carbon footprint. In fact, if you’re a designer who wants to take recycling a step further, Re.Verso can help with that.

What Coke Contains — Food for Thought The Vons grocery store two miles from my home in Los Angeles, California sells 12 cans of Coca-Cola for $6.59 — 54 cents each. The tool chain that created this simple product is incomprehensibly complex. Each can originated in a small town of 4,000 people on the Murray River in Western Australia called Pinjarra. Pinjarra is the site of the world’s largest bauxite mine. Bauxite is surface mined — basically scraped and dug from the top of the ground. The bauxite is crushed and washed with hot sodium hydroxide, which separates it into aluminum hydroxide and waste material called red mud. The bar is transported to Downey, California, where it is rolled flat in a rolling mill, and turned into aluminum sheets. Coca-Cola is made from a syrup produced by the Coca-Cola Company of Atlanta. The second ingredient, caramel coloring, gives the drink its distinctive dark brown color. A much smaller proportion of the syrup is flavors. The top of the can is then added.

Qmilk - the bio Milk Fibre Founder of the company is Anke Domaske who originally was searching for chemically untreated clothing for her stepfather with cancer. Eventually milk proteins came to her interest. Those had already been processed to textiles in the 1930s, but the fibers were treated with various chemicals and produced in a complex process. Qmilk started as a classic start-up – however not in a garage, but in a kitchen. In April 2011 the Qmilch GmbH was founded.

UP' Magazine L'entreprise britannique BAE Systems, spécialisée dans la défense et l'aéronautique, travaille sur un concept de "peau intelligente" à destination des avions. Le concept de « peau intelligente » que développe BAE Systems est pensé comme un réseau de nanocapteurs qui recouvrent la surface d’un appareil. Chaque capteur dispose de son alimentation et de son système de communication sans fil. Cette technologie permettra à un aéronef de surveiller l'apparition de problèmes potentiels en permanence et de les détecter avant qu'ils ne posent de danger. Cette peinture intelligente pourrait être prête d’ici une quinzaine d’années estime Lydia Hyde, la directrice de recherche qui pilote ce projet. (Source et Photo ©BAE Systems)

Smart indoor garden discreetly grows plants and herbs One doesn't necessarily need a green thumb and lush plots of land in order to cultivate quality crops. A Canadian-based team has launched a product aimed at individuals who want to grow plants and herbs year-round without all the guesswork. The Grobo indoor gardening system features smart tech designed to simulate ideal growing conditions while providing real-time information to users. Indoor, automated, and/or smart growing systems are nothing new. One could take a trip to a local nursery and pick up ready-to-go pods that need only periodic watering and daily sunshine, not unlike the Click and Grow Smart Herb Garden. Standing at nearly 4 ft (1.2 m) tall, the rectangular-shaped Grobo could be casually mistaken for an Ikea bookshelf – ideal for those who don't have space for a greenhouse the size of a vending machine. Not only does the Grobo app connect individuals to a community of growers to share stats, recipes, and tips, but it serves as a complete dashboard. Source: Grobo

Bioesters UP' Magazine L'amélioration de la qualité de la vie quotidienne constitue depuis toujours une des préoccupations majeures de l'homme. Sans oublier la rénovation thermique des bâtiments, l'un des grands enjeux de notre société dans un contexte de raréfaction des matières premières énergétiques. C'est dans ce cadre que s'inscrit la recherche perpétuelle de nouveaux matériaux plus performants, plus écologiques, mieux adaptés aux contraintes et exigences de l'époque. Les tendances actuelles, soutenues désormais par l'évolution des réglementations, font de la performance énergétique un critère de recherche déterminant dans l'élaboration de matériaux innovants : isolation, matériaux de construction,... ; il s'agit de repenser complètement les habitudes qui ont régi l'industrie de la construction les trois dernières décennies et optimiser les propriétés des matériaux de demain. De tout temps, des matériaux nouveaux ont accompagné le progrès scientifique et technique. Les matériaux de demain

Turning toxic vegetable refuse into nutritious animal feed A new technology, known as transport engineering, aims to remove unwanted substances from edible portions of plants. (Photo: Wikimedia Commons) A Danish research team has developed a method that can prevent unwanted toxins in oilseed rape from reaching the edible parts of the plant. This means that the rapeseed cake – the refuse remaining after the oil has been expressed from the rapeseed – may in the future be used in feed for pigs and poultry on a completely different scale. “We have developed a new technology that we call transport engineering,” says Professor Barbara Halkier, Head of Center of Excellence for Dynamic Molecular Interactions (DynaMo) at Copenhagen University’s Department of Plant and Environmental Sciences. Rapeseed plants fill their seed with toxic defence compounds The researcher explains that all plants produce toxins to defend themselves against disease attacks and herbivores. There’s a great potential in our findings. Barbara Halkier And indeed there was.
