Cob (material)

Cob (material)
Building a wall out of cob. Cob, cobb or clom (in Wales) is a natural building material made from sand, clay, water, some kind of fibrous or organic material (straw) and earth. Cob is fireproof, resistant to seismic activity,[1] and inexpensive. It can be used to create artistic, sculptural forms and has been revived in recent years by the natural building and sustainability movements. In technical building and engineering documents such as the Uniform Building Code, cob may be referred to as an "unburned clay masonry" when used in a structural context. 'Cob stitch' repair on old traditional cob cottage in Devon, England Cob is an ancient building material, that may have been used for building since prehistoric times. The walls of a cob house were generally about 24 inches thick, and windows were correspondingly deep-set, giving the homes a characteristic internal appearance.

Courses June 2012, not far from Carmarthen: Henge of roundhouse being built in Bath, March 2012. The Shifty Singers sing in the Bath roundhouse at the end of week 3: Here is a video from that course showing the making of a reciprocal frame roof. Roundhouses The best way of building a roundhouse is in a group, and the best way to learn how to do it is in a group. There have been three courses in the first half of 2013. The second was the fire circle near Cardigan. Here we are - photo by Elena Mia Fortuny: There are no more courses definitely planned for 2013, but there is a small course for the Welsh language Urdd centre near the West Wales coast in October, and a grand project to make a roundhouse for a big bread oven, and the first work on a roundhouse in France in August/September 2014 so email me if you want to be sent info. Pictures and videos from courses We had a great time building the roundhouses of cobwood and strawbale at Plan-It Earth. Here is a little stop motion film of the building:

Rocket stove A small manufactured rocket cooking stove A rocket stove A rocket stove is an efficient cooking stove using small diameter wood fuel which is burned in a simple high-temperature combustion chamber containing a vertical chimney and a secondary air supply which ensures almost complete combustion prior to the flames reaching the cooking surface. The principles were described by Dr. Larry Winiarski from Aprovecho in 1982 and stoves based on this design won Ashden Awards in both 2005 and 2006. Design[edit] A rocket stove achieves efficient combustion of the fuel at a high temperature by ensuring a good air draft into the fire, controlled use of fuel, complete combustion of volatiles, and efficient use of the resultant heat. A rocket stove's main components are: The fuel magazine can be horizontal, with additional fuel added manually, or vertical, with fuel automatically fed. Recent Adaptations[edit] There have been a number of new cook stove designs based on the original rocket stove. Dr.

VIDEO: Amazing Recycled Bicycle Machines Bicycle recycling is nothing new. But a Guatemalan nonprofit is turning trashed bicycle parts into innovative, electricity-free machines that you have to see to believe. Based in San Andrés Itzapa, Guatemala, Maya Pedal Asociación accepts donated bikes from the U.S. and Canada, which volunteers either recondition to sell or break down to create a range of pedal-powered machines called Bicimáquinas. Bet You’ll Love: VIDEO: Soda Bottles Upcycled into Solar Light Bulbs Founded by engineer and bicycle enthusiast Carlos Marroquin, the organization harnesses pedal power to perform a number of tasks that would otherwise require electricity, which is often unavailable in smaller villages. Each Bicimáquina is hand-crafted in Maya Pedal’s warehouse in San Andrés Itzapa, where volunteers operate a bike repair service and build everything from tile makers to nut shellers to blenders – all made from old bicycles.

Caves have a natural beauty to them, as anyone who has been to Carlsbad Caverns can tell you, but Ra Paulette is an expert. Artist Ra Paulette has spent the last decade excavating tunnels and passageways, and carving designs and benches in the sandstone cliffs in northern New Mexico. He spends his time carving a sandstone cave that he found, turning it into a wonderful subterranean space full of light. With no one but his dog for company, Paulette created different designs and styles for every cavern, giving each one very specific qualities and textures. It is a unique creation that will blow away your mind! The thought of spending so much time underground without human contact might make some feel claustrophobic, but to this artist, it’s a calling.

The Most Beautiful Green Home Building Construction Project Ever? Design Published on April 9th, 2009 | by ziggy April 9th, 2009 by ziggy My jaw dropped when I first watched this video tour of a beautiful owner-built green building construction project in Oregon. This particular green building is made entirely out of cob, a mixture of clay, sand, and straw. Meka Bunch of Wolf Creek, Oregon built this stunning cob house over a four year period. Check out the video and photos of Meka’s cob cottage for yourself: [youtube= This couch is made of cob and features wood storage tucked underneath, right next to the stove. The kitchen features many shelves and nooks built directly into the cob walls, and also includes a small compost chute. The wood stove is surrounded by cob for thermal mass, and includes a warm nook with shelf to culture yogurt. Gorgeous custom-made cob staircase. The north porch of Meka’s cob cottage. I must say that Meka’s cob house design is one of my favorite projects that I’ve seen. About the Author

Sustainable Alternative Homes - Freeing Humans For Further Evolution Source: | Original Post Date: December 11, 2013 – I would like to invite you to relax. I’m guessing you are doing some reading or web-surfing to free your mind after a long work day. Or maybe it’s your day off and you are entertaining yourself with Facebook and online news. For most of us, life is a constant movement from or to. Generally we base our schedules and the bulk of our lives around tasks we must do in order to sustain our lives and survive and this often leaves very limited time and energy for the things we actually desire or have passion for. It seems on this cusp of human transformation, nearing the end of 2013, the topics of conversation, especially in the worldwide ‘conscious’ community, are often veering in the directions of human enlightenment, breaking free of the system, and DNA reactivation- remembering and reclaiming who we are as BEINGS. One project in particular that is especially exciting is called EarthShips.

Introduction to Permaculture - 18 part webinar with Bill Wilson of Midwest Permaculture Interplanting and Beyond, An Excerpt from Gaia’s Garden // May 1st, 2012 // No Comments » // Uncategorized This coming Sunday, May 6, is International Permaculture Day! To celebrate, this week we’ll be sharing some classic excerpts from one of our perennial bestsellers, Gaia’s Garden by Toby Hemenway. Permaculture is more than just a way to garden, it applies systems-thinking to every facet of our relationship to the earth and each other. Using different veggies’ strengths and weaknesses to avoid competition and maybe even get them to help each other out is called interplanting. The following is an excerpt from Gaia’s Garden: A Guide to Home-Scale Permaculture by Toby Hemenway. Vegetable gardeners have some experience in creating plant communities. Monocultures deplete the soil, provide a sumptuous feast for pests, and dull the senses. One simple interplanting scheme mixes onions, carrots, and lettuce in the same garden bed. See also:

Insect Hotels Insect Hotels Provide a home to pollinators and pest controllers. Tidy gardens, lawns and lack of dead wood, mean less and less habitat for wild bees, spiders and ladybugs. A wildlife stack can harbor numerous beneficial insects and amphibians. Wildlife stack. Bug hotel in Oakham, UK at the Lyndon Nature Reserve, built by Paul Stammers and Michelle Househam.

Insect home or bug bank, on the grounds of Oxburgh Hall in North Norfolk. Insect hotel in Helmsley, UK. Solitary bees are different from social bees (such as honey bees) in that every female is fertile and makes individual nest cells for her offspring. The female typically creates a series of compartments (cells) and within each cell she will lay an egg on top of its future food source. Insect hotel in Hoofddorf, Holland.
