Domerama 100' Geodesic Dome for Aquaponics The bigger a dome gets, the better it's energy efficiency. Thank you for viewing my entry. I will post Instructables for all of the different aspects of the project as we complete them. When I am asked about building an aquaponics center that has an area of almost 8,000 square feet, I always have the same answer. With domes, bigger is better. There are several reasons. In "Critical Path," under Geodesic Dome efficiency, Buckminster Fuller says: "Every time the linear dimension of a symmetrical structure is doubled (ie. 1 -> 2) the surface area of the enclosure increases at a two to the second-power rate (i.e., 2^2). With a 100' diameter dome, we will have almost 8,000 square feet to set up our aquaponics system. Couple that with it being twice as hard to heat and cool, and you may begin to see the picture. The prize money rounded to $100 (with tax:) 1760 6ft. 2x6's - $2800 616 Hubs - $25,000 *note* I edited this up from $5,000 as I got the quote back after contest closed 8,000 sq ft.
Tensile structure Most tensile structures are supported by some form of compression or bending elements, such as masts (as in The O2, formerly the Millennium Dome), compression rings or beams. A tensile membrane structure is most often used as a roof, as they can economically and attractively span large distances. History This form of construction has only become more rigorously analyzed and widespread in large structures in the latter part of the twentieth century. Tensile structures have long been used in tents, where the guy ropes and tent poles provide pre-tension to the fabric and allow it to withstand loads. Russian engineer Vladimir Shukhov was one of the first to develop practical calculations of stresses and deformations of tensile structures, shells and membranes. Antonio Gaudi used the concept in reverse to create a compression-only structure for the Colonia Guell Church. Steady technological progress has increased the popularity of fabric-roofed structures. Linear structures where:
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.
Green eco-friendly custom homes and interiors by Solaleya Designer Patrick Marsilli proposes a revolutionary solar structure Passive solar energy: Rotate your house away from the sun in summer to cool down and towards the sun in winter to warm up (on demand or automated rotation system). Optional Integrated solar panels to store energy as well as several possible ecological options for better energy efficiency. Structural strength: Anti-cyclonic Its aerodynamic form has proven resists without any damage to a wind up to 240km/hour (Taiwan Domespace resisted Cyclone Tim in 1994 and some others without deterioration). Anti-seismic The seismic ray that would make a 10 story building collapse turns around the ring gear of fixation without finding any perpendicularity. Every Domespace is erected over an elastomeric belt that works as a "silencer block"... like a piece of rubber that cushion vibrations. Arches are solidly anchored to a steel ring gear itself fixed to a pedestal made of reinforced concrete. Unparalleled structural integrity Pleasant habitat:
Eco-Dome: Moon Cocoon The Eco-Dome is a small home design of approximately 400 square feet (40 sq. meters) interior space. It consists of a large central dome, surrounded by four smaller niches and a wind-scoop, in a clover leaf pattern. Learning and building an Eco-Dome is the next stage after building a small emergency shelter and provides hands-on learning experience in the essential aspects of Superadobe construction. It's small size of approximately 400 square feet (interior space), makes it a manageable structure for the first time owner builder. The finished "very small house" is self-contained and can become a small guest house, studio apartment, or be the first step in a clustered design for community use in an Eco-Village of vaults and domes. Built from local earth-filled Superadobe coils (earth stabilized with cement or lime).Tree free.Maximum use of space through alternative options. Note: The Eco-Dome plan is a part of the Cal-Earth educational and research program.
Luis de Garrido Luis de Garrido Talavera (born 13 November 1967) is a Spanish architect. Luis de Garrido works with sustainable architecture in Spain. During recent years he has only accepted projects where very strict (chanta) ecological, health and environmental criteria are always respected. Biography Luis de Garrido studied architecture in the PUV Polytechnic University of Valencia where he graduated with a doctorate. During this time he taught a large range of subjects at the information technology faculty at the Polytechnic University of Valencia (UPV), the information technology faculty at the Polytechnic University of Catalonia (UPC), in the school of telecommunications. He has also worked as a visiting professor at the School of Architecture, Edinburgh, Scotland. Currently, Luis de Garrido directs an architectural firm en Valencia, Spain where is designs sustainable architecture. External links Webpage for ANAVIF in Spanish
