Valeurs isolation sciure / copeaux. Sans titre. Sandhills, Nebraska : le berceau de la construction en botte de paille. Introduction Construire une maison en paille, vous n’y pensez pas !
Le vent va en disperser les brins, l’incendie les réduire en cendres et la pluie les pourrir ! Pourtant, l’on dénombre 5000 bâtiments en paille en France, et l’on s’apprête à fêter le centenaire de la maison Feuillette, toujours debout – et fière – à Montargis. La construction en paille a déjà une longue histoire. C’est dans les Plaines nord-américaines où les pionniers, ne disposant ni de bois ni de pierre, édifièrent, pour la première fois, maisons, granges et écoles en botte de foin. Le grand désert américain. Zome Dome et Cie. Voici un programme qui va vous permettre de construire plusieurs types de structures.
Il est en cours de développement ... toutes remarques sont les bienvenues. Les charpentes en forme de voûte et de dômes avec la technique du "nid d'abeille" sont proposées, ainsi que les zomes, les héliyourtes et maintenant les géodômes ... Il permet, une fois la structure modélisée, de l'exporter au format Wavefront Obj, qui est un format 3D compatible avec le majorité des logiciels 3D (Blender, Sketchup (avec ajout plugin), 3DS ...).
[Digestion] Digester Heating by a thermosiphon system. Jaime Marti Herrero tallerbiogas at hotmail.com Tue Nov 20 08:33:08 CST 2012 hi everybodyabout solar passive heating we have published a paper about it. i attachat the document.the key looks to be to gain solar radiation throuhgt the top of the digester (with greenhouse in very cold regions) and to insulate the tank from the soil. the difference between solar radiationgain+insulation and without that is (for the same weather) 13ºC. we have digesters in both cases, and we are reaching 30ºC for the slurry when solar passive heating is applied, but only 17ºC of slurry temperature when no solar gain or insulation is used.keep in touchjaime ----- Jaime Martí Herrero CIMNE (www.cimne.com).

We’ve made some modifications since last winter, and things are looking good. As with all on-farm experiments, we’re learning as we go. But egg production is good and, as we continue to tweak things, all-round chicken happiness is high. The Rawbale Chicken House is working well – keeping the chickens warm and snug while allowing for good airflow. And the sloping run seems to be working well too – especially now that we’ve made bush-terraces in it to slow the flow of mulch downhill! The idea with this chicken run (or straw yard, as it’s become known) is that weekly we dump a wheelbarrow full of straw in at the very top of the run, which over time the chickens scratch down the hill. The run itself now has horizontal bush logs every 2-3 meters or so. All in all, this is certainly a system that seems to be working. How to grow your own mulch?
Growing my own mulch has long been a goal of mine.
We use a lot of mulch in the nursery and garden and at the moment we have no problem sourcing straw but if/when the day comes that the farmers start using their own straw to improve their soil (which is becoming a more common practice), We'll be needing to step up our mulch growing efforts. Currently, we grow enough mulch to sustain the perennial beds and around 10 % of the annual beds but rely on imported straw for mulching the other 90% of annual vegetable and nursery beds.
Cas de substitutions par certaines SAFER : simple habileté, ou à la limite de la légalité ? La Cour des comptes s‘est d'abord inquiétée de cette pratique parce qu'elle prive les collectivités locales et l'État du montant des droits de mutation, au bénéfice des seules entreprises privées que sont les SAFER.
Une première critique forte alors que ces collectivités estiment avoir beaucoup de difficultés à équilibrer leurs budgets, mais une critique strictement utilitariste. Pigs turning compost. Salatin refers to these as "pigaerators".
The pigs turn the commpost for you while rooting for goodies in the pile. I've read Salatin's books and checked around on the internet where several folks have reported success with this technique. Combustion-Free Hot Water at the Whole Systems Research Farm.
