ETFE Film, Fabric Membrane - Birdair Tensile Architecture. Used for both roofs and facades, ETFE film presents unlimited design options due to the material's light weight, flexibility and transparency.
ETFE film can be used in place of traditional glass and plastic for permanent or temporary structures. ETFE allows roof or wall weight to decrease drastically compared with glass. Because the material does not shatter upon impact, architects are also using ETFE in place of glass in applications where blast mitigation is a concern. When ETFE film is used in a two- or three-layer model incorporating an air space, it provides an excellent insulating capability, as effective as insulating glass.
Depending on project specification, there are several ETFE films available to customize UV protection and light control, including transparent, matte, white and printed. The sustainable material is recyclable and provides superior durability. PVC Sheets - Clear - PVC SHEETS- Order Online. Low cost geodesic dome greenhouse kit. Geodesic dome calculator - acidome.ru.

What if there was a way to produce an abundance of organic food using 98% less water, while producing up to ten times more food in the same amount of area and time? What if you could achieve this using 1/4 the amount of energy? Imagine producing organic food in a system that does not require fertile soil, saves you labor, makes you a good living and is incredibly sustainable? Well the exciting news is that such a system of growing food exists! Does all this sound too good to be true? Explore this website and learn about this incredible system and its successes and applications around the world! At a time of global climate change, depletion of resources, pollution of water and huge losses of top soil worldwide, there has never been a more important time to learn about Aquaponics! ETFE. ETFE is the fluoropolymer-material ethylene tetrafluoroethylene which is used in structural membrane constructions in thicknesses from 0.05 to 0.25 mm.
ETFE was invented by the Dupont corporation. Its primary use was as an insulating material for use in the aeronautics industry. It was considered as a highly specialized material with no significant mainstream applications, though it was often the preferred material when old polythene sheet used for greenhouse polytunnels required replacement. The ETFE chemical structure Difficult to tear, highly transparent and a useful life up to 50 years were benefits difficult to ignore, and in time it would find applications in sails to roofs. Greenhouse dome. Homesteading. Murray Hallam's Practical Aquaponics. Aquaponics from a practical perspective.
Aquaponics. Aquaculture is the symbiotic cultivation of plants and aquatic animals in a re-circulating system. Growing Power uses Tilapia and Yellow Perch to fertilize a variety of crops and herbs using aquaponics. Aquaponics is the method of growing crops and fish together in a re-circulating system. In the Growing Power aquaponics model crops grow vertically on raised beds. Types of fish we grow: Yellow Perch Yellow Perch is a species of perch found in the United States and Canada and is a glacial lakes species.
Yellow Perch are also in short supply. What does Perch eat? Tilapia Originally found in Africa, Tilapia has been farmed for more than 2,500 years. 226. ASTAF-PRO - igb. Ein A quaponik- S ystem zur emissionsfreien T om a ten- und F isch- Pro duktion in Gewächshäusern Das Ziel des Projektes ist es Gemüse und Fisch in einem Gewächshaus unter emissionsfreien Bedingungen zu produzieren.
Hierzu wird das Wasser aus der Aquakulturanlage, welches wichtige Nährstoffe enthält, mechanisch und biologisch aufgereinigt und bei Bedarf der Pflanzenanlage zugeführt. Wasser und gelöste Nährstoffe werden von den Pflanzen aufgenommen. Das evaporierte Wasser wird mittels Kühlfallen aus der Gartenhausatmosphäre extrahiert und der Aquakulturanlage wieder zugeführt. Dieses Wasser wird erneut verwendet und verringert den täglichen Wasserverbrauch auf unter 3% Frischwasser. Eyes on the Solar System. Visible Earth: Browse by Topic.

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.
