Barcelona Will Be a Big Test For HotSpot 2.0 Wi-Fi Connections

alphadogg writes “There are currently several million smartphones certified to run on a ‘HotSpot 2.0’ Wi-Fi network, which promises automatic Wi-Fi authentication and connection, and seamless roaming between different Wi-Fi hotspot brands, and eventually between Wi-Fi and cellular connections. In November, about 400 smartphone users finally got a chance to do so — in Beijing, China. The next big public demonstration of what’s confusingly referred to as both Hotspot 2.0 and Next Generation Hotspot will be in February: an estimated 75, 000 attendees at the next Mobile World Congress in Barcelona will be able to take part.” Read more of this story at Slashdot.

Chicago Transit System Fooled By Federal ID Cards

New submitter johnslater writes “The Chicago Transit Authority’s new ‘Ventra’ stored-value fare card system has another big problem. It had a difficult birth, with troubles earlier this fall when legitimate cards failed to allow passage, or sometimes double-billed the holders. Last week a server failure disabled a large portion of the system at rush hour. Now it is reported that some federal government employee ID cards allow free rides on the system. The system is being implemented by Cubic Transportation Systems for the bargain price of $454 million.” Read more of this story at Slashdot.

Coca-Cola and Dean Kamen Team-Up Will Provide Fresh Drinking Water for Millions Via Kiosk

Coca-Cola is known the world over for producing its sugary (or fructose-y) namesake beverage. But in keeping with the ever-greening times, they now hope to form a secondary reputation as a provider of safe, clean drinking water. In Heidelberg, South Africa, Coke recently launched their first EKOCENTER , a 20-foot shipping container meant to serve as a retail kiosk, community center and social hub in impoverished rural areas. To draw bodies, each EKOCENTER is loaded up with a Slingshot , a water purification machine invented by Dean Kamen. Segway inventor Kamen’s Slingshot is amazing. Taking up as much space as a small refrigerator, the thing can run on cow poop and uses no filters, yet can turn any water source into potable water–cranking out up to 1, 000 liters a day. And it can run for five years without even requiring any maintenance! The Slingshot was more than a decade in the making, and with Coca-Cola’s backing and global distribution network, is well-positioned to make a significant impact on global health through the EKOCENTER. And in addition to the Slingshot functionality, each container contains solar cells that can be used to power charging points or refrigeration for medicine. Following the South African launch, Coke plans to get the containers into 20 countries in need by 2015, getting safe drinking water into the mouths of millions. (more…)

World’s First Fully Bionic, Mind-Controlled Leg Goes for a Walk

When Zac Vawter lost his leg in a motorcycle accident a few years ago, he thought he’d never walk like a normal person again. But today, the 32-year-old software engineer can climb stairs, wiggle his toes and stroll through parks. The only difference is that one of his legs is a mind-controlled robot . Read more…

Walgreens To Build First Self-Powered Retail Store

MojoKid writes “We hear about green deployment practices all the time, but it’s often surrounding facilities such as data centers rather than retail stores. However, Walgreens is determined to go as green as possible, and to that end, the company announced plans for the first net zero energy retail store. The store is slated to be built at the corner of Chicago Avenue and Keeney Street in Evanston, Illinois, where an existing Walgreens is currently being demolished. The technologies Walgreens is plotting to implement in this new super-green store will include solar panels and wind turbines to generate power; geothermal technology for heat; and efficient energy consumption with LED lighting, daylight harvesting, and ‘ultra-high-efficiency’ refrigeration.” Read more of this story at Slashdot.

And Now, a Tiny Japanese Roomba… for Your iDevice Screen

Although it seems that we’ve been soliciting your opinions with a simple “Yea or Nay” quite a bit lately—regarding this and this , for starters—we just as often herald instances of “hell in a handbasket” to connote examples of design or specific products that confound us. And while I’d surmise that a new product called the Automee S is an example of chindōgu , the fact that it will reportedly available for 1575 Yen (about $17) next month seems to be at odds with the spirit of ‘unuseless design.’ Unfortunately, the product page is in Japanese, so we’re relying on New Launches’ translation regarding details and specs. They write that “the little one has three tires for maneuvering and two made of paper which do the cleaning. The onboard sensors prevent the Automee S from falling off the edges and also lets it clean the entire surface evenly.” New Launches also notes that it takes four minutes to clean a phone and eight to clean a tablet, which makes it good for 45 and 22 complete cleans on a single AA battery.

Microsoft to provide cloud services for city of Chicago in four year deal

There’s a cloud hanging over the second city and it belongs to Microsoft . In a release issued today, Chicago Mayor Rahm Emanuel announced plans to migrate the city’s 30,000 civil servants to a cloud-based solution for email and all desktop applications . Apart from the $400,000 the four-year deal is projected to save taxpayers annually, the move to Microsoft’s cloud computing for government platform will also help to bolster efficiency and streamline communication internally, as the city goes from three conflicting email systems to just one. According to the city’s Department of Innovation and Technology, this department-wide transition should reach completion by the end of 2013. It’s not the Windy City’s first big leap into remote storage — its hosted Department of Aviation data there for some time — but it does mark Emanuel’s commitment to modernization . Hit up the break for the city’s official PR.

Flotspotting: Bike Bad-assery, Part 3: Saline Airstream

It’s been a minute since we saw the last badass compressed air-powered motorcycle , so seeing as digital designer / 3D modeler Pierrick Huart finally got around to uploading the Saline Airstream to his Coroflot portfolio this past September, it’s worth revisiting even a year and a half after its debut. Back in March 2011, Technologic Vehicles reported that Huart was a member of one of seven teams of students from the International School of Design (ISD) in Valciennes, France, who submitted projects to a speedy brief from “Les Triplettes de Bonneville.” (As such, we’d be remiss not to credit fellow team members Vincent Montreuil, Julien Clément, Thomas Duhamel and Benedict Ponton.) Described as “crazy French DIYers,” the triplets selected the Saline Airstream design, when features an Alu-Magnesium chassis by Daniel Heurton and weighs in at only 102kg (224 lbs). Meanwhile, Wes Siler of Hell for Leather explains the technology behind the engine far better than I could ever hope to: Pneumatic engines using compressed air as their power source aren’t new. If you’ve used an impact wrench or other pneumatic workshop tool, then you’ve used a compressed air engine. The technology enjoys particular interest in France, where Victor Tatin conceived an airplane powered by it all the way back in 1879. That’s where Les Triplettes des Bonneville, the team that will run the Airstream and the makers of its engine come from. The company making the engine is MDI, which is pushing the technology in low-speed, urban vehicles. Like electricity, compressed air is zero emissions (well, technically it’s emitting air…), but unlike electricity, fill ups don’t take hours. You can fill a compressed air tank from a compressor or storage unit in the same time it takes to fill up with gasoline. The downside is that power output and therefore performance are so far somewhat limited, something Les Triplettes are trying to address. The function of a pneumatic piston engine of the kind employed here is incredibly simple. Air is stored in the Airstream’s three tanks at 3,626psi and fed into the engine at 363psi, where it expands, pushing the piston down. That pistons’s return path exhausts the air through a valve, just like in your gasoline-powered motorcycle. (more…)

Must-See Video: Real-Time English-to-Mandarin Speech Translation via Microsoft Research

As you might have noticed, we’ve had quite a bit of Asian design coverage lately (with a few more stories to come): between the second annual Beijing Design Week , a trip to Shanghai for Interior Lifestyle China and last week’s design events in Tokyo , we’re hoping to bring you the best of design from the Eastern Hemisphere this fall. Of course, I’ll be the first to admit that our coverage hasn’t been quite as quick as we’d like, largely due to the speed bump of the language barrier. At least two of your friendly Core77 Editors speak passable Mandarin, but when it comes to parsing large amounts of technical information, the process becomes significantly more labor-intensive than your average blogpost… which is precisely why I was interested to learn that Microsoft Research is on the case. In a recent talk in Tianjin, China, Chief Research Officer Rick Rashid (no relation to Karim) presented their latest breakthrough in speech recognition technology, a significant improvement from the 20–25% error of current software. Working with a team from the University of Toronto, Microsoft Research has “reduced the word error rate for speech by over 30% compared to previous methods. This means that rather than having one word in 4 or 5 incorrect, now the error rate is one word in 7 or 8.” An abridged transcript of the talk is available on the Microsoft Next blog if you want to follow along: In the late 1970s a group of researchers at Carnegie Mellon University made a significant breakthrough in speech recognition using a technique called hidden Markov modeling which allowed them to use training data from many speakers to build statistical speech models that were much more robust. As a result, over the last 30 years speech systems have gotten better and better. In the last 10 years the combination of better methods, faster computers and the ability to process dramatically more data has led to many practical uses. Just over two years ago, researchers at Microsoft Research and the University of Toronto made another breakthrough. By using a technique called Deep Neural Networks, which is patterned after human brain behavior, researchers were able to train more discriminative and better speech recognizers than previous methods. Once Rashid has gotten the audience up to speed, he starts discussing how current technology is implemented in extant translation services (5:03). “It happens in two steps,” he explains. “The first takes my words and finds the Chinese equivalents, and while non-trivial, this is the easy part. The second reorders the words to be appropriate for Chinese, an important step for correct translation between languages.” Short though it may be, the talk is a slow build of relatively dry subject matter until Rashid gets to the topic at hand at 6:45: “Now the last step that I want to take is to be able to speak to you in Chinese.” But listening to him talk for those first seven-and-a-half minutes is exactly the point : the software has extrapolated Rashid’s voice from an hour-long speech sample, and it modulates the translated audio based on his English speech patterns . Thus, I recommend watching (or at least listening) to the video from the beginning to get a sense for Rashid’s inflection and timbre… but here’s the payoff: (more…)

Surprising News About Bicycle-Powered Electricity Generators

That hourglass-shaped device is the PowerPac, an energy storage device meant to be powered by a human on a stationary bicycle. Conceived of by South African design firm Ideso , the PowerPac won a Red Dot Design Award in the “Best of the Best” category. “Our aim was to create an aesthetically pleasing, user-friendly and functional design that marries the fluidity of cycling with dynamic power generation,” says Ideso MD, Marc Ruwiel. “It can be used by avid cyclists who can reduce CO2 emissions and generate their own electrical power, while enjoying a good workout at home.” I’m all for people-powered electricity generators, and I would’ve loved to have one of these during the recent blackout, but something struck me in the copy: “…An average cyclist could fully charge the battery from empty with 80 minutes of cycling and 132Wh of charge/potential energy can be stored in the battery.” The “Wh” designation stands for watt-hour , and “132Wh” means you could power a 132-watt device for 1 hour. For 80 minutes of cycling to yield, say, just over two hours of light from a 60-watt bulb sounds like a low yield, doesn’t it? My first thought was, can that be right? I did a little digging, and here’s what I found. It turns out hooking a bicycle up to something that directly powers a mechanical device is a fairly efficient way to generate energy. Rig a bicycle up to drive a sewing machine or a hand mixer and you get decent bang for your buck. But the second you get batteries and electricity involved, the efficiency drops way, way off. An article in Low-tech Magazine called ” Bike powered electricity generators are not sustainable ” explains why: …Generating electricity is far from the most efficient way to apply pedal power, due to the internal energy losses in the battery, the battery management system, other electronic parts, and the motor/generator. These energy losses add up quickly: 10 to 35 percent in the battery, 10 to 20 percent in the motor/generator and 5 to 15 percent in the converter (which converts direct current to alternate current). The energy loss in the voltage regulator (or DC to DC converter, which prevents you from blowing up the battery) is about 25 percent. This means that the total energy loss in a pedal powered generator will be 42 to 67.5 percent…. And it even turns out that the bicycle itself has mechanical inefficiencies that suck up more energy: (more…)
