Our money system guarantees that inequality will get worse - Here is the evidence » Positive Money Written by Graham Hodgson (Guest Author) on . The gap between the very richest and the rest of us has increased continuously over the last thirty years. Did you know that top 10% of population earns on average 6 times more than the bottom 90%? Many factors contribute to this growing gap, but one of the most significant is least understood: the role of money creation by banks. As a volunteer for Positive Money, I’ve spent much of the last two years investigating the connections between inequality and the money system. Here are some of the problems that arise when money is created by banks when they make loans: The entire money supply is effectively ‘on loan’ from the banks. I’ve written up these initial findings into a 16 page academic paper, Banking, Finance and Income Inequality, which you can download below. Within society, a moderate degree of inequality is considered to provide a stimulus to economic progress and general prosperity. Technical Annex We have to act now! 1. 2. 3.

A Lamp which Produces an Electrical Current as a Result of it’s Kinetic Energy The 3d printed nylon polymer lamp designed by Dr. Margot Krasojević is suspended by a spindle whereby it’s weight and form contribute to the angular momentum vector as it spins along its axis of rotation; it is affected by minor environmental changes such as temperature and air currents which rotate the light along its path of velocity. The light has a motion sensor diode clamped between both suspended 3d printed sections which powers the battery lighting the LED when in motion. As a result of it’s form, the light speeds up tremendously due to it’s conservation of angular momentum, the form of the light reduces it’s rotational inertia affecting it’s rotational speed which must increase to maintain constant angular momentum resulting in a brighter light. The light has been influenced by the physics behind ice skater spinning/a spinning top. -> EVOLO SKYSCRAPERS 2 - Limited Edition Book

Architects are starting to 3D print houses—but without a house-sized printer A couple of months ago, Dutch architect Janjaap Ruijssenaars announced that he was building a curvy, loopy and for some reason, largely see-through building, to be made with the help of Enrico Dini’s D-Shape 3D printer. The project would cost up to 5 million euros ($6.4 million) and be completed in 2014. Janjaap Ruijssenaars’s twisty, loopy 3D-printed building. Another group quickly piped up, declaring that a similar project they were working on would be done even faster and cheaper. Softkill Design’s web-like confection of a building. This month, another Dutch company jumped into the fray. DUS Architects plan to use non-traditional 3D printing methods to build a traditional house along a canal in Amsterdam. 3d house-printing—it certainly sounds like a brilliant idea. But what does this 3d house-printing actually mean? How it works A cast concrete sample detailing the resolution of the combined additive (3D printing) and subtractive (robotic milling) fabrication process being developed.

‘Spending more time outside is a really political act’ David Bond, the 'marketing director for nature' and his daughter Photo © Jack Barnes There is a scene in new documentary film Project Wild Thing where director David Bond sits under a tree for an hour. It may not sound like the most electrifying cinematic moment, but as he listens to the birdsong and watches the wind rippling across the water, you can feel your own breath slowing down in appreciation of the scene. It is this ‘power to ground’ us that leads Bond to describe nature as a “wonder drug”: one that most of us, especially children, are not taking enough of. The amount of time British children spend outdoors has shrunk by 50% in a generation, for example, and their roaming area – the space in which they are allowed to play unsupervised – by 90%. Bond’s enthusiasm is infectious. “Given a little encouragement, children revel in the bugs and the fresh air and the leaves and the mud” Project Wild Thing is released nationwide on Friday 25 October but is already making waves.

3D-printed ceramic bricks developed for large-scale construction Nov.1, 2012 After a six-week residency program at the European Ceramic Work Centre in the south of the Netherlands, Brian Peters, co-founder of Amsterdam-based Design Lab Workshop, developed a 3D-printed ceramic bricks project - "Building Bytes". Peters has been working with desktop 3D printers for years and he wanted to use a desktop 3D printer to build large-scale construction. He added a custom extrusion head to produce ceramic bricks using fixed resources (a desktop 3D printer, limited capacity of the material storage system and the properties of clay). This fabrication system, including the materials and technology, allows Building Bytes to be accessible worldwide. These 3D-printed ceramic bricks can be used for building large-scale architectural structures. Ribbed brick applications: Columns, Window or Door Openings Printing time: 15 minutes Layer height: 2mm Material: White earthenware (slip cast recipe) Finish: Raw – unglazed Dimensions: 15cm x 15cm x 4cm "X" brick Interlocking brick

Auto produzione casalinga di biogas con il Digestore Compatto biogas il gruppo A.R.T.I. ha realizzato un sistema innovativo che consente l’auto produzione casalinga di biogas da scarti alimentari di tipo farinaceo e vegetale, si tratta di Digestore. Con tale brevetto il gruppo A.R.T.I. ha vinto il premio Ashden per l’Energia Sostenibile nella categoria “food securety. Il prodotto può essere impiegato per la produzione di gas, per la cottura quotidiana degli alimenti e per l’acqua calda sanitaria. Grazie a questo sistema, c’è un risparmio notevole in termini ambientali ed economici: l’ambiente verrebbe alleggerito della presenza di rifiuti e nello stesso tempo si eviterebbe l’utilizzo di GPL e di petrolio che incidono gravemente anche sull’economia delle famiglie. Inoltre l’alimentazione dell’impianto è a costo zero in quanto si utilizzano solo ed esclusivamente scarti alimentari. Le caratteristiche energetiche del sistema rendono il processo più veloce, più efficace e con minore utilizzo di materia rispetto al tradizionale impianto a biomassa animale.

Dutch architect to build "endless" house with 3D printer Jan.15, 2013 Dutch architect Janjaap Ruijssenaars (39) from Universe Architecture in Amsterdam designed a one-piece building which will be built on a 3D printer. He hopes the so-called Landscape House can be printed out latest in year 2014. One surface folded in an endless möbius band. Ruijssenaars works together with mathematician and artist Rinus Roelofs to develop this project using 3D printing technology. (Images: Universe Architecture) Ruijssenaars plans to print every piece in size of 6 x 9 meters using a massive 3D printer called D-Shape. Ruijssenaars says Dini has suggested to print out the form only. Together with a Dutch construction company, Ruijssenaars is working with Dini to realize the idea. The landscape house is developed for joining Europan, a European competition of ideas for young spatial designers. The landscape house will be a landscape in the landscape. 本站所有文章版权归3ders.org所有，未经许可不得翻译或转载。

Our Invisible Revolution Republished from truthdig.com By Chris Hedges “Did you ever ask yourself how it happens that government and capitalism continue to exist in spite of all the evil and trouble they are causing in the world?” the anarchist Alexander Berkman wrote in his essay “The Idea Is the Thing.” “If you did, then your answer must have been that it is because the people support those institutions, and that they support them because they believe in them.” Berkman was right. It appears that political ferment is dormant in the United States. "It is certain now that a popular revolt is coming." Revolution usually erupts over events that would, in normal circumstances, be considered meaningless or minor acts of injustice by the state. “Because revolution is evolution at its boiling point you cannot ‘make’ a real revolution any more than you can hasten the boiling of a tea kettle,” Berkman wrote. Revolutions, when they erupt, appear to the elites and the establishment to be sudden and unexpected.
