Build your own Bamboo Domes This is page 95 of "Domebook Two", a book that was published in the 70's and is very hard to find. It was written by Pacific Domes (not the same as Pacific Domes), and I was able to find it at the local library. Bamboo grows fast, is free material for a dome framework. It might be possible to suspend a tent skin or mosquito netting inside, or pull a stretch cloth over the outside and shoot foam. Tools: a pocket knife and string. The following instructions were prepared by R. Dome Assembly The geodesic dome, as shown in the assembly diagrams, contains two different joints: a B joint which occurs at the vertices of all pentagons formed, and an R joint which occurs at all other points. Cutting and Measuring the Members There are only two different lengths of members used in the erection. For a 5/8 dome, 80 B members and 90 R members are required. A line of color can be drawn around the bamboo members at each measuring point. Cross Assembly Cross Tying Stage 1 Assembly Stage 2 Assembly Prop It
Chapter 9: Mathematics -- Build a homemade geodesic dome A Geodesic Dome Some years ago I built a geodesic dome out of ½ inch galvanized steel electrical conduit, to serve as an aviary for chickens and small parrots. I wrote a computer program to calculate the proper lengths of steel tubing, and draw the diagram shown below: The dome is made from three different lengths of tubing. I used colored stickers on the tubes to mark the different lengths -- red for the long ones, violet for the medium lengths, and green for the short ones. You can see those colors in the drawing. The ends of the tubes are smashed flat with a hammer, and then holes are drilled in the flat ends for a bolt to go through to connect up to six of the tubes together. For this project, something a little more modest in size is required. For the first attempt at a smaller dome, I used bamboo kebab skewers and gumdrops. You will need these materials for the gumdrop dome: Click on photo for a larger picture The dome is made of pentagons and hexagons. We end up with a nice dome.
A Milan Skyscraper With A Forest Inside It We may need to start building our parks in the sky. In the 1850s, New York City needed a place to escape from its own urban crush. It was easy enough to evict more than a thousand poor tenement dwellers and re-landscape the heart of Manhattan, creating what we know as Central Park. Today, such a project would prove far more difficult, if not impossible, in most of the world’s major cities. Vertical greenspace may be one answer to that problem. The Bosco Verticale towers taking shape in the northern Italian city of Milan, although private residential towers, show the technology is more than possible. The vertical forest spreads out one hectare of woodland across 27 floors. This doesn’t make them particularly expensive. Other architects are working on the same challenge by taking the biological metaphor to extremes. But most green buildings today merely evoke the forms found in nature.
Conduit Dome Tips Conduit, or EMT seems to be the material of choice for domes at Burning Man. Conduit is easy to work with, relatively inexpensive, and plated so painting isn't necessary. This page will provide tips for making conduit framed domes. STEP 1: Deciding on a frequency The first thing you need to do is figure out what type of dome you want to build. If this is your first dome, the 2 or 3 frequency domes are recommended. These domes require a fewer number of struts, and therefore less confusion. STEP 2: What Size? STEP 3: Calculating Strut Lengths This is where the Dome Calculator comes in. Step 4: Eliminating Waste This part is tedious, but worth the effort because it will save you money and you won't have to feel bad about throwing away tons of wasted pipe. Step 5: Cutting the struts Cut the tubes according to the strut factors plus 1½". STEP 6: Flattening the ends OK, there are a few ways to do this part. Step 8: Bending the Struts Now the struts need to be bent to the correct angles.
Domerama The Fact That Changed Everything: Will Allen and Growing Power Vertical Farm | Food on GOOD This content is brought to you by GOOD, with support from IBM. Click here to read more stories from The Fact That Changed Everything series and here to read about other Figures of Progress. In 1993, when Will Allen bought the three-acre plot of land in Milwaukee that would later become Growing Power, he didn’t know that he would be starting a food movement. The son of a sharecropper, Allen was itching to farm full-time and saw the new plot as a likely business opportunity. Allen soon received a call from Milwaukee’s Hunger Task Force, however, which changed his market-focused mindset and led to his founding of Growing Power. “It was part of my proposal to the city that I would to teach kids about how to grow food and about food systems—that was my other purpose,” says Allen. In its nineteenth year, Growing Power continues to thrive in its mission. All told, the foods produced by Growing Power feed about 10,000 people in Milwaukee.
Monolithic domes Monolithic dome office Monolithic Domes are constructed following a method that requires a tough, inflatable Airform, steel-reinforced concrete and a polyurethane foam insulation. Each of these ingredients is used in a technologically specific way. This technology was developed by the Monolithic Dome Institute (MDI). The dome, when finished, is earthquake, tornado and hurricane resistant (FEMA rates them as "near-absolute protection" from F5 tornadoes and Category 5 Hurricanes). [edit] Ecoshells MDI has also developed the technology to build so-called "EcoShells". EcoShells are easy to build, easy to teach others to build and fast to construct. It has been estimated that Haiti, for example, needs approximately 200,000 EcoShells to house up to 1 million people. [edit] Use of Basalt Fibers The basalt reinforcing for the monolithic dome/ecoshell can now be made of basalt fibers.

El barro, las manos, la casa. Email+ 1Email Esta obra, dirigida por Gustavo Marangoni, es un gran documental didáctico sobre construcción natural.Filmado principalmente en la localidad de El Bolsòn, provincia de Rìo Negro, sur de la cordillera Argentina; fue realizado con el apoyo de la secretaría de Cultura de la Presidencia de la Nación. Y fue declarado de interés por el programa “Arquitectura y Construcción con Tierra” de la Facultad de Arquitectura, Diseño y Urbanismo de la Universidad de Buenos Aires. Se trata de una mirada general a este tipo de construcción: sus características, su historia, los prejuicios que tenemos sobre la tierra como material de construcción, sus virtudes y también sus desventajas (y como superarlas). Jorge Belanko charla con vecinos aclarando dudas generales como por ejemplo, si es posible realizar este tipo de casas en zonas lluviosas como las nuestras, los diferentes estilos de construcción, la posibilidad de la autoconstrucción, entre otros temas.
