Magnus Larsson Turning dunes into architecture

This is known as the angle of repose, and a prime example is the surface of sand dunes.

They took photographs, they fed the photographs into their computer program, and that computer program shaped a sand dune and then took that sand dune shape and turned it into at their instructions, using standard software with slight modifications a set of instructions for pieces of wood.

The land is mostly flat, and gently undulating covered with bush and grasses covering the sand dunes, and areas of larger trees.

Other activities are taking place in areas such as sand dune fixation, forest management and the promotion of agroforestry.

New orders for the independent tank battalion were to break off the attack and to attack from the north, through the sand dunes.

The site comprised a mosque, a minaret, (now demolished), and a maqam, as well as at least nine wells dispersed in the sand dunes nearby.

This infantry attack was to occur under the cover of darkness, following a secondary approach to Um Katef through the sand dunes.

According to the reports, soil conservation continues to be given high priority by the organizations in their efforts to preserve the environment, alongside sand dune fixation strategies.

The most common interpretation of large, chevron shaped bed forms is that they are a form of parabolic dune, and that most examples are generated by wind action.

The Asian TPN 3 on rangeland management in arid areas, including the fixation of shifting sand dunes, was launched in 2001.

The Yukon Territorial government made efforts to protect Carcross Desert in 1992, but failed due to opposition from locals who use the dunes for recreational purposes.

In fact, in some areas of the US and other countries, only extensive dune fields and vegetated areas are used to separate buildings from the seashore.

In collaboration with Columbia University, Ben Gurion University had also designed interferometric radars to monitor dune and sand migration and evaluate the aftermath of the Indian Ocean tsunami and the quality of water in the Red Sea.

The way it does this is it comes out at night, crawls to the top of a sand dune, and because it's got a matte black shell, is able to radiate heat out to the night sky and become slightly cooler than its surroundings.

OK, so this is our movie of the equatorial region of Titan, showing these dunes. These are dunes that are 100 meters tall, separated by a few kilometers, and they go on for miles and miles and miles.

But, if I had something like a TED wish, it would be to actually get it built, to start building this habitable wall, this very, very long, but very narrow city in the desert, built into the dunescape itself.

In 2002 a pilot project design meeting for TPN 3 approved the systematic design for testing on pilot project plots the application of mulching, soil conditioning and windbreaks for sand fixation and rangeland protection.

Each storm scours the atmosphere, washing out dust, soot, trace chemicals, and depositing them on the snow pack year after year, millennia after millennia, creating a kind of periodic table of elements that at this point is more than 11,000 feet thick.
