Papier liant ( fait maison) - Sous les Tilleuls Le papier liant, papier-béton ou papercrete qu'est-ce que c'est ? C'est une invention états-unienne datant de la fin des années vingt qui a pour but de faire un béton à partir de papier. Le principe ? on prend du papier on ajoute de l'eau on le malaxe on ajoute du sable et pour finir du ciment ou de la chaud. La recette ? 1 cement, 3 paper, 4 sand maj : 50% wet paper pulp/ 30% damp earth/ 10% dry sand/ 10% Portland cement/ 60% wet paper pulp/ 20% damp earth/ 15% dry sand/ 15% Portland cement/ 65% wet paper pulp/ 25% damp earth/ 10% Portland cement/ 70% wet paper pulp/ 15% damp earth/ 15% Portland cement/ Personnellement j'ai modifié la recette. papier eau paille de lavande terre chaux Je suis plutôt dans un hybrid-adobe comme disent les états-uniens. Technique ? Passons maintenant au coté technique de la chose. Sur les enveloppes, les fenêtres en plastique ne sont pas super, il faut penser à les retirer avant de les malaxer. Pourquoi faire ? Pour moi
Hempcrete.com.au: The Australian Hempcrete Technologists The future according to Google's Larry Page Note: On Jan 3, as Fortune published this article, the Federal Trade Commission ended its investigation of Google's search practices saying it found no evidence that the company manipulated search results in violation of antitrust laws. The European Commission and other regulators continue to investigate the issue. FORTUNE -- When Sir Martin Sorrell, CEO of WPP Group, the giant advertising agency, visited Google this past fall, CEO Larry Page sent a car to pick him up at the Rosewood Hotel about 20 miles away.

Scotland Community Shows The World Why All Homes Should Be Made Out of Hemp Many people are becoming aware of ways to live that are more harmonious with the planet. It seems that we are transitioning to a very ancient understanding of how to operate here on Earth, with a very advanced ‘know how’ of technologies and methods to begin making that transition. New ways of living are coming to light and although you may not hear about them often, communities all over the world are starting to implement them. A new sustainable housing project in the Northwest of Scotland will use industrial hemp as the main building material. An English housing company that specializes in hemp-based construction called ‘Hemcrete Projects,’ supplied the system. Hemp has many uses, over 50, 000 to be exact. Combined with insulation made from Hemp fibre, Hembuild provides the village in Scotland with houses made from a combination of insulation and thermal inertia. Hempcrete is very versatile as it can be used for wall insulation, flooring, walls, roofing and more. Sources:
The Rise of the Robots by Robert Skidelsky Exit from comment view mode. Click to hide this space LONDON – What impact will automation – the so-called “rise of the robots” – have on wages and employment over the coming decades? Nowadays, this question crops up whenever unemployment rises. In the early nineteenth century, David Ricardo considered the possibility that machines would replace labor; Karl Marx followed him. Then the fear of machines died away. For some countries, this long-run prospect might be uncomfortably close. Recently, automation in manufacturing has expanded even to areas where labor has been relatively cheap. Now the substitution of capital for labor is moving beyond manufacturing. For those who dread the threat that automation poses to low-skilled labor, a ready answer is to train people for better jobs. As a recent article in the Financial Times points out, in two areas notoriously immune to productivity increases, education and health care, technology is already reducing the demand for skilled labor.
Le liant-papier Construire sa maison à moindre coût, soit : 2,3 euros/m² de mur au lieu des 18 euros actuellement avec des matériaux conventionnels. Quelle aubaine pour les personnes ayant de petits revenus et qui méritent aussi d’accéder à un habitat de qualité. A l’heure où l’accession à la propriété est de plus en plus élitiste et où l’on voit nos banquiers, assureurs, architectes et autres, rouler dans de grosses voitures, il y a vraiment quelque chose à faire pour changer tout ça. Cette alternative est bien entendu réservée aux gens qui pensent que l’on est toujours mieux servi que par soi-même ou qui se voient refuser un prêt pour l’acquisition d’une maison bas de gamme de type Bouy… ou autre, et cela, malgré un salaire et un emploi fixe. Lorsqu’un banquier nous refuse un prêt pour l’achat d’un habitat, plusieurs solutions s’offrent à nous : on peut se prostituer pour augmenter ses revenus, demander une forte augmentation à son employeur, voler, hériter, ou encore opter pour l’auto construction.
Hemp Facts Industrial Hemp Facts(No THC here) Prototype Lotus Elise The Eco Elise , released at the British Motor Show in 2008, uses a host of sustainable materials to make up the body and trim, including hemp, "eco wool," sisal and a new high-tech, water-based paint. WOW! Hemp is the miracle plant of our time, breathing in 4x the carbon dioxide (CO2) of trees during it's quick 12-14 week growing cycle.

The inevitability of smart dust I’ve put forward my opinion that desktop computing is dead on more than one occasion, and been soundly put in my place as a result almost every time. “Of course desktop computing isn’t dead — look at the analogy you’re drawing between the so called death of the mainframe and the death of the desktop. Mainframes aren’t dead, there are still plenty of them around!” Well, yes, that’s arguable. The desktop will increasingly belong to niche users. For the rest of the world? People never wanted computers; they wanted what computers could do for them. Everyday objects are already becoming smarter. The sensors you carry with you may well generate more data every second, both for you and about you, than previous generations did about themselves during the course of their entire lives. The end point of this evolution is already clear: it’s called smart dust. Makes desktop computing look sort of dull, doesn’t it?

Hemp building What is it? It’s building with ‘hempcrete’ which is a mixture of the following three components: hemp ‘shiv’: hemp is a plant that has been used for millennia for making textiles. The shiv is the waste from the textile industry – the woody / pithy core of the stemsa lime binderwater These 3 components are used in different ratios depending on the strength or insulative properties you require for the part of the building it’s going to be used on. A field of hemp on a farm in France. Hempcrete can be used for walls, for floors and as an insulation layer in roofs / ceilings – but it’s not structural, i.e. it’s not strong enough to support the weight of a building alone, and so it tends to be cast around a timber frame, where it provides stiffness and insulation. In areas where hemp is grown for textiles, hemp shiv has been used for generations as animal bedding. Shuttering being added to a very simple timber frame for a hempcrete kitchen extension; note the bags of hemp shiv and lime binder.
How Hunter-Gatherers Maintained Their Egalitarian Ways: Three Complementary Theories As regular readers of this blog know, I have in previous posts commented on hunter-gatherers' playfulness; their playful religious practices; their playful approach toward productive work; their non-directive childrearing methods; and their children's playful ways of educating themselves. In all of those posts I emphasized the egalitarian, non-hierarchical nature of hunter-gatherer society. In today's post I present three theories as to how hunter-gatherers maintained the egalitarian ethos for which they are justly famous. I think all three of the theories are correct. First, before I get to the three theories, I must address this question: Is it true that hunter-gatherers were peaceful egalitarians? During the twentieth century, anthropologists discovered and studied dozens of different hunter-gatherer societies, in various remote parts of the world, who had been nearly untouched by modern influences. This is true for play among animals as well as for that among humans. [2] Lee, R.

The Nauhuas - Why We Like Hempcrete home > current projects > Nauhaus prototype > hempcrete > The goal of environmentally conscious building design is to create buildings that create a healthy indoor environment while supporting a healthy outdoor environment. After years of experience building, designing, and researching we’ve come to the conclusion that the best way to accomplish this goal is through combining cutting edge building science with what are commonly called “natural building” practices. High performance building science allows us to create buildings that use almost no energy to run, therefore reducing the size and price of the renewable energy system required to produce on site all the energy required to run the building. One of our biggest challenges has been to create a wall system that serves these design objectives.
