3-D Printing a House The University of Southern California is testing a giant 3D printer that could be used to build a whole house in under 24 hours. Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a nozzle on a gantry, this squirts out concrete and can quickly build a home according to a computer pattern. It is “basically scaling up 3D printing to the scale of building,” says Khoshnevis. The technology, known as Contour Crafting, could revolutionise the construction industry. The affordable home? Contour Crafting could slash the cost of home-owning, making it possible for millions of displaced people to get on the property ladder. It could even be used in disaster relief areas to build emergency and replacement housing. For example, after an event such as Typhoon Haiyan in the Philippines, which has displaced almost 600,000 people, Contour Crafting could be used to build replacement homes quickly. It could be used to create high-quality shelter for people currently living in desperate conditions. “At the dawn of the 21st century [slums] are the condition of shelter for nearly one billion people in our world,” says Khoshnevis, “These buildings are breeding grounds for disease a problem of conventional construction which is slow, labour intensive and inefficient.” As Khoshnevis points out, if you look around you pretty much everything is made automatically these days – “your shoes, your clothes, home appliances, your car. The only thing that is still built by hand are these buildings.” How
The answer is yes. Yes there are solutions to the challenges in Africa and they are available today. The biggest challenge is political will as an extension of corruption and it’s cousins. I suggest that it is time for philanthropic activities by Africans who are willing to help solve these challenges as individuals or collectives. This website will now focus its efforts in communicating this message of hope. I will dwell on how it will work as opposed to how it will not work. Join me in reshaping the destiny of the African continent.
Students of today wonder how the content they are forced to learn and pass even with a wise variety of choices will help them in their future careers. In fact I’m of the opinion a lot of them are not even sure about the kinds of jobs they will do. Several things have happened to cause a disconnect between what they are learning and how they are living and also a future that has become increasingly more difficult to predict. The agricultural and industrial revolutions are well understood and their impact clearly visible. The information revolution has caught us off guard because it’s growth has been non-intuitive, it’s been exponential. The world has become a lot smaller and a lot more virtual. Many of the job titles in the technology industry did not exist a decade ago and more are added each year. Students walk into and out of unmotivated classrooms because they have to. The whole education system is a production line style where students are places into age groups and spend hours wondering what time the lesson will end. It has become increasingly difficult to motivate students who have seen celebrities make money out of a passion divorced entirely from organised instruction. Look at sportspersons and Hollywood actors. Look also at the technology and idea entrepreneurs who have made a fortune with internet businesses in search and social networking. The role of the teacher as the all knowing person in the classroom has diminished as information has gone
Photographer Rick Smolan discusses some of the more advanced technologies made possible by Big Data. Smolan created The Human Face of Big Data along with Jennifer Erwitt: http://goo.gl/Xk1h2H Transcript — Data exhaust is probably my least favorite phrase in the big data world ’cause it sounds like something you’re trying to get rid of or something noxious that comes out of the back of your car. But basically everything we’re doing now is being recorded and it never is going to go away. If you ever plan to run for office, if you’re a teenager, remember everything you do, every tweet, every Facebook posting, every picture you put on Instagram will be there forever for journalists and politic – for your competition to dig up. The whole idea of data exhaust is that between our smartphones and our credit cards and our easy passes and all the other things that are collecting information about us, there’s this three-dimensional portrait of each of us and who we are. And that is being analyzed and sold to the highest bidder and is being used to understand peoples movements, behavioral patterns. I’ll give you an interesting example of that. There’s a company in Boston called Ginger IO that has a smartphone app that can predict two days before you get depressed, that you’re going to get depressed. I was very dubious when I first heard about this and I actually spoke to the gentleman who runs it, Anmol. And he said — I
