Solar-Powered 3D Printer Turns Desert Sand Into Glass The sun's rays can be harnessed to power everything from homes to gadgets, but one graduate student is using the sun to create a super-printer capable of printing elaborate glassware. Markus Kayser took his graduate project all the way to the sands of the Sahara in Egypt to create his innovative idea dubbed the 'Solar Sinter'. The incredible design uses a 3D digital printer and the sun’s rays to turn the sand into incredible glass bowls and sculptures that are out of this world.
Afghanistan's Amazing DIY Internet | Fast Company The Afghan city of Jalalabad has a high-speed Internet network whose main components are built out of trash found locally. Aid workers, mostly from the United States, are using the provincial city in Afghanistan's far east as a pilot site for a project called FabFi. It's a broadband apart from the covert, subversive "Internet in a suitcase" and stealth broadband networks being sponspored by the U.S., aimed at empowering dissidents, but the goal isn't so different: bringing high-speed onilne access to the world's most remote places. Residents can build a FabFi node out of approximately $60 worth of everyday items such as boards, wires, plastic tubs, and cans that will serve a whole community at once.
DIY internet spreading through Middle East and Africa : The Thin Green Line Did you know that people in Kenya, Afghanistan and Pakistan are building their own wireless networks out of found materials? Just $60 of everyday items such as wood, cans, plastic tubs, wires and car batteries can provide internet service for hundreds of people. It’s like the “telephone” of your youth and the best MacGyver episode ever, all rolled up into one. Courtesy MIT’s Fab Lab
The Carbon Neutral Emax Excalibur Hybrid Yacht is Covered in Solar Panels The Emax Excalibur solar hybrid luxury yacht isn’t shy about its carbon neutral status: it is literally covered in solar panels from prow to stern. The green vessel, built by Sauter Carbon Offset Design and the Ned Ship Group, is built from kevlar and carbon and is completely carbon neutral. But the coolest thing about this new ship is that you can plug it in and return energy to the grid–over 50 megawatts per year. According to Sauter Carbon Offset Design, “The plug-in Emax Excalibur has a top speed of 30 knots and can harvest enough energy per year to offset up to 3,000 nautical miles of carbon-neutral cruising at 18 knots.”
Nico Jara's Pedal-Powered Potenza Concept Vehicle Stores Kinetic Energy The Potenza, a vehicle by Argentinian designer Nico Jara, is simple in concept: a human-powered four-wheel bike that stores energy from pedaling and later converts it into kinetic energy. It is designed for use in large cities as a zero-emissions way to get around without using a traditional bicycle. The elegant design features four spoked wheels and a canopy up top to protect drivers from the elements.
The one-seater solar aircraft is similar in size to a large plane, but it only weighs as much as a regular car. It is powered by 12,000 solar cells that cover the plane’s wings. They absorb the sun’s energy, and in turn charge batteries that power the 10-horsepower motors that spin the plane’s four propellers. Solar Impulse Airplane Makes Public Debut at Paris Air Show
Green Power Island Could Power Copenhagen Sustainably The proposed Green Power Island off the coast of Copenhagen seeks to be an alternative energy super center for the country. Designed by Gottlieb Paludan, the massive man-made island will utilize wind power, solar power, seawater pumps, and produce marine biomass for biofuel. Improving on the pumped hydro-renewable energy concept, Green Power Island could become Copenhagen’s alternative energy center, providing energy for all of the country’s residents around the clock. Wind power is an incredible resource, but when the wind doesn’t blow, neither do the turbines.
Scientists Developing Talk-Powered Cell Phones Attention, chatterboxes of the world: one day you may be rewarded for your talkativeness with power to juice up your cell phones. Researchers in Korea have figured out a way to turn the main ingredient in calamine lotion (zinc oxide) into a material that converts sound waves into electricity — and eventually, it could be used to power up cell handsets. In a study, the scientists fashioned a piezoelectric material (nanowires sandwiched between electrodes) out of zinc oxide that generates 50 millivolts of energy. That’s not enough to power a cell phone — most handsets require a few volts — but the researchers have high hopes that they will be able to generate more power from future versions of the piezoelectric material. So eventually, the more we talk on the phone, the more battery life we’ll have.
Solar photovoltaics are, depending on the day, between 8-15% efficient meaning much of the sun’s energy’s is lost as heat. While solar thermal systems offer a way to harvest this heat energy for heating water or interior spaces, this option has usually displaced the electricity generating PV on rooftops. A new system from SolarWall, the SolarDuct PV/T, offers a combination of solar photovoltaic and solar thermal in one assembly providing a means to heat and power from the sun with one product. The system is an evolution of the SolarWall system, a vertical mounted solar thermal and heat recapture system that transfers heat into or away from a building’s HVAC mechanicals depending on the season. The SolarDuct PV/T is based on the same principle of capturing heat from the sun and heat generated from excessive solar gain on buildings. Solar Energy Cogeneration Solution from SolarWall
You know the old story, right? You come into possession of plans for the Empire's moon-sized space station, and now they've come to capture you. What to do? Well, if you've got access to a Kinect, an iPad, and the String SDK, you're in luck. The folks at LAAN Labs demonstrated a nifty little hack that can turn 3D data recorded using the Xbox 360 peripheral into a Princess Leia-esque augmented reality image playable on the Apple tablet. Check the video below -- unless you're a scruffy-looking nerf herder, that is. Kinect / iPad hack should help you get Obi-Wan's attention (video)

Pack your bags - we'll be gone for 100 years I don’t think it’s at all suspicious that the supergeeks of DARPA, the US military’s Defense Advanced Research Projects Agency, which brought us flesh-eating robots and Project Orion – “the spaceship powered by atomic-bomb turds”, is now calling for papers for its 100 Year Starship Study. I think it’s awesome! Especially because there’s a lazy half million in prize money for the best idea.
As a shopper, have you ever pondered what sort of mark-up the retailer has slapped on to the pair of Levi jeans or adidas runners that you're about to try on? Turns out consumers reckon a 35 per cent mark-up by the shop would be fair in order to make a profit, according to a survey by the Australia Institute out today.
