NASA Can Now Create Objects Using Electron Beams



Instead of using traditional 3D manufacturing, NASA has developed an electron beam fabrication system capable of creating any object. And hey, if it uses electron beams. Electron beams, people. That means it's awesome.

The new method, called Electron Beam Freeform Fabrication (EBF3), uses the electron beam to melt raw material inside a vacuum. The beam can create any mechanical part you want for a small fraction of the cost of previous methods:

Normally an aircraft builder might start with a 6,000-pound block of titanium and machine it down to a 300-pound part, leaving 5,700 pounds of material that needs to be recycled and using several thousand gallons of cutting fluid used in the process.

With EBF3 you can build up the same part using only 350 pounds of titanium and machine away just 50 pounds to get the part into its final configuration. And the EBF3 process uses much less electricity to create the same part.

NASA says that this method will not only help aircraft manufacturers on Earth, but also astronauts, who may one day use it to make replacing parts during missions in remote bases. [NASA]

What is good design?

Good design is not just about looks - functionality, purpose and originality also play a role.
BY Alice Rawsthorn | Jun 11, 2008

I've learned (the hard way) not to do it, but if random strangers - like taxi drivers, or whoever's sitting on the next airplane seat - ask what I do and I'm rash enough to confess to being a design critic, they invariably follow up with: "So what is good design?"

The stock answer is that good design is generally a combination of different qualities - what it does, what it looks like and so on.

But as our expectations of design change, so do those qualities and the relationships between them. Let's look at what they are - and where they stand - right now:

1. WHAT IT DOES

This is the non-negotiable. Whatever it is, and whatever other great qualities it has, it can't be well designed if it doesn't do something useful.

Even better is if that something couldn't have been done before. That's always been so, all the way back to the early 200s BC when Emperor Qin Shihuangdi conquered China equipped with a very early example of good design.

The armies of the day were led by archers who made their own weapons, with the result that each archer's arrows could only be fired from his own bow.

Qin insisted that all arrows be made to the same length with identical, replaceable tips. If an archer ran out during a battle, he could use his colleagues', and if he died, his ammunition wasn't wasted.

Even today it's possible for something to qualify as good design simply by fulfilling its function efficiently. Take Google's logo. Stylistically, it's awful with a dodgy font and the twee illustrations for the customised "holiday logos" with which Google marks special occasions such as Christmas Day, St Patrick's Day and landmark birthdays.

But those tweely illustrated logos are so much fun - like a gift from Google - that they make us think more fondly of it. Job done.

2. HOW IT LOOKS

Few things enrage design purists more than suggesting that good design is all about looks. It isn't.

But Qin's arrows and Google's logo are exceptions, because function is seldom enough either, and there's nothing wrong with enjoying eye candy.

That's why textbook examples of good design - such as Marcel Breuer's 1920s chairs, or Dieter Rams' 1950s electrical products for Braun - tend to score highly on form and function.

Photo-Stealth Camouflage Technology Unveiled

Military Wraps Research&Development, Inc. has unveiled the new photo-stealth technology at the U.S. Special Operations trade show (SOFEX 2007). Photo-Real and Photo-Stealth are trademarks of Military Wraps and are in patent pending. This technology is ” a direct result of daily feedback from specific battlefields from all over the globe”.

Sounds very interesting, but what exactly does this mean? Well, the photo-stealth camouflage uses site-specific photographs printed on vinyl-adhesive wraps.

This technology can only work in specific terrains, due to the photo-realistic scene patterns, once an item has finished a tour of duty it can be re-wrapped and sent to another specific location. The camouflage is so realistic that any soldier or equipment can virtually disappear in the battlefield environment. Stealth is a key word in today’s military. When people hear “stealth” their probably think F-117 Nighhawk or F-22 Raptor, the classic angle-shaped designs. That technology is only used to deceive radars and, as you’d imagine, is quite expensive. Photo-stealth on the other hand will not deceive radar, IR and such, but it will deceive the human eye. If the enemy can’t see you, he can’t shoot you.

Learning How Materials Work In Space To Make Them Better On Earth

ScienceDaily (Sep. 22, 2009) — What's about the size of a large refrigerator, weighs a ton and may help pave the way for new and improved metals or glasses here on Earth?

It's the Materials Science Research Rack -- a new laboratory on board the International Space Station.

This facility will allow researchers to study a variety of materials -- including metals, alloys, semiconductors, ceramics, and glasses to see how the materials form, and learn how to control their properties. The results from experiments conducted in the facility could lead to the development of materials with improved properties on Earth.

Where's your tablet now Apple!



It feels like the whole world is holding its breath for the Apple tablet. But maybe we've all been dreaming about the wrong device. This is Courier, Microsoft's astonishing take on the tablet.

Courier is a real device, and we've heard that it's in the "late prototype" stage of development. It's not a tablet, it's a booklet. The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre.

The Courier user experience presented here is almost the exact opposite of what everyone expects the Apple tablet to be, a kung fu eagle claw to Apple's tiger style. It's complex: Two screens, a mashup of a pen-dominated interface with several types of multitouch finger gestures, and multiple graphically complex themes, modes and applications. (Our favorite UI bit? The hinge doubles as a "pocket" to hold items you want move from one page to another.) Microsoft's tablet heritage is digital ink-oriented, and this interface, while unlike anything we've seen before, clearly draws from that, its work with the Surface touch computer and even the Zune HD.

Conductive Rubber

"Metal Rubber

Chemists Create Self-assembling Conductive Rubber

April 1, 2007 — Polymer chemists have created a flexible, indestructible material, called metal rubber, that can be heated, frozen, washed or doused with jet fuel, and still retain its electricity-conducting properties. To make metal rubber, chemists and engineers use a process called self-assembly. The material is repeatedly dipped into positively charged and negatively charged solutions. The positive and negative charges bond, forming layers that conduct electricity. Uses of metal rubber include bendy, electrically charged aircraft wings, artificial muscles and wearable computers."

Sonumbra solar powered construct provides shade and light



Exploring the alternative sources of energy and low cost lighting, design research studio Loop.pH in collaboration with Riso DTU, the national laboratory for sustainable energy in Denmark, has come up with an experimental body of work that other than offering light shade for a group of people. The “Sonumbra,” as described by the studio, creates an umbrella like formation, finished with fastening the strands of lights, which not only provides shelter from the scorching heat of the sun during the day, but also offers light for a local community at night. For it collects energy from solar cells, embedded within its canopy, and turns it into sustainable as well as low-cost electricity to illuminate your nights. The Sonumbra will be on display, from September 19 to 27, under “In Praise of Shadows” exhibition as part of the London Design Week.

Self-healing electronics using carbon nanotube-filled microcapsules

Microcapsules filled with carbon nanotubes could be used to repair electronic circuits   (...

Dropping an electrical device such as a mobile phone or laptop can prompt a few anxious moments as you rush to see whether your beloved device has survived the fall. Now researchers at the University of Illinois at Urbana-Champaign are working to make such incidents a little less distressing - they're developing a self-healing first-aid kit for electrical systems that could stop circuits failing and lead to safer, longer lasting batteries.

The technology centers around microcapsules filled with carbon nanotubes. In much the same way that tiny liquid-filled capsules rupture to repair a scratch in the self-healing materials we’ve looked at previously, the microcapsules could be placed on failure-prone areas and would rupture to release conductive nanotubes, bridging a break when stress causes a crack in the circuit.

Paul Braun, a professor of materials science and engineering at the University of Illinois who is leading the research project, told Technology Review, “we want to address common failures in cell phones and other portable electronics.” He also predicts that the rate of these failures may increase with the rise of flexible electronics, which are subject to much more mechanical stress.

Self-healing circuits could lead to lighter, cheaper and more efficient devices, particularly in critical, hard-to-repair situations such as satellites or submarines. Currently, engineers build redundancy into such systems to guard against a total failure, but if the devices were able to heal themselves such redundancy systems wouldn’t be necessary.

There is also potential for the technology to be used in batteries to restore the electrical conductivity of damaged battery electrodes, thereby preventing a short circuit that could lead to the battery exploding.

Currently the researchers are working on ways to precisely position the microcapsules using a technique called electrospraying, as well as looking at ways to remove broken microcapsule shells from the electronic device to reduce contamination.

The team’s research appears in the paper Microcapsules containing suspensions of carbon nanotubes, which appears in the Journal of Materials Chemistry.

Scratchable Input

Chris Harrison, a researcher at Carnegie Mellon University whose human-computer interaction work we've written about previously, will demonstrate his new scratch inputtechnology. The system turns any surface into an instant input device by sensing the unique sound produced when a fingernail is dragged across it.

The interface is small enough to fit into a mobile device, Harrison says, and could thereby turn any surface the device is placed upon into an interface.

Feature Story - Alberto Alessi

Object Lessons

The maestro of Italian design lays out his (flexible!) system for enforcing creative discipline.

Alberto Alessi, head of the world-famous design factory that bears his name, doesn't like to travel much anymore. And why would he? With an office in Crusinallo, Italy, deep in the heart of the famed Lombardy region -- home to some of the world's most revered design firms -- and a 300-year-old house under renovation in the misty hills around Lake Orta, not much is more appealing than his own casa and cucina. Plus, there's his new hobby as a vintner, raising pinot and chardonnay grapes. "They're difficult to grow," he concedes, "but I'm always looking for a challenge."

The grandson of Giovanni Alessi, who founded the family business in 1921 to make metal products, Alberto, 63, has cultivated a distinctive design aesthetic by pursuing an unlikely vision: that homey domestic items are as worthy of first-rate creative thinking as grand buildings or attention-grabbing chairs. And he has recruited to the cause an ensemble of global design celebrities -- Philippe Starck, Richard Meier, Aldo Rossi, Robert Venturi, Ron Arad, and Ettore Sottsass, to name a few.

"I can't think of any other company that gets close to Alessi's stable of designers, level of quality, and consistency of discovery," says Reed Kroloff, director of the Cranbrook Academy of Art, home of American modernism. Alessi spoke to a jam-packed audience at Cranbrook on a recent, rare trip to the United States. "They were in this game a long time before Target and Ikea, at a higher level of quality. More than anyone else, Alessi understands that design is more than a value-added proposition. It's a fundamental value."

In 1980, Alessi challenged 11 noted architects to create tabletop coffee and tea sets, in which the pots would mimic buildings and the tray would serve as a "piazza." The collection was a design sensation (if not a commercial one: The limited edition sets sold for as much as $25,000) and toured U.S. museums. Then Alessi asked architect Michael Graves to design a teakettle, and Graves's vision caught fire.

The Graves kettle, with its cool blue handle and perky, red-bird-topped spout, became a best-seller -- more than 1.5 million units -- and a design icon. Subsequent knockoffs for Target have sold many more and launched Graves into a second career as a product designer.

Puckish flourish has since become a signature motif in Alessi products. Witness Alessandro Mendini's corkscrews shaped like parrots, devils, and little girls, or Stefano Giovannoni's Orientales collection of playful tablewares in the shape of banana boats, goldfish, and monkeys. Even in this dark recessionary retail climate, those whimsical products are still selling well, says Paolo Cravedi, managing director of Alessi U.S.A., who oversees the company's retail stores in the United States. "Every day, people come in our store and their eyes go wide: Oh, geez, we really needed something like this!"

Alessi stopped in New York on that trip to Cranbrook, with his 8-year-old daughter, and, like any good tourist, hit F.A.O. Schwarz, Toys "R" Us, and the Apple Store. We sat down with Alessi and, after a fine lunch, he shared detailed insights about his company's unique design process.

FC: Many Alessi products seem to have something playful about them. Is that an intentional strategy?

I do not know where this whimsicality came from. [Late Italian designer Achille] Castiglione said to me, "You ask me to design pots and pans. But I never use pots and pans. I don't know where to start!" So maybe in order to balance this strange effect, the designers add some humor. It is not compulsory. I do believe design is a new form of art and poetry, but with the strange destiny of bringing a little bit of joy to people. In that sense, humor probably helps.

What do you look for in recruiting designers?

We are open to anybody. There are 200 good horses in my stable now, and I have to keep them in good shape. I add 5 to 10 new ones every year. Sometimes I follow my own curiosity and contact them. Sometimes designers get in touch with us. Every year, we also organize six or seven workshops with schools we want to work with.

Some folks in your stable -- Philippe Starck, Ron Arad -- have pretty big egos. Any tips for dealing with design divos?

Very basic strategies, like not putting them together.

Do you use much market research to develop your products?

I use the Formula, a mathematic model that I developed at the beginning of the 1990s to decide if we should put a new prototype into production.

That sounds very scientific, very unpoetic!

The Formula was provoked by my brothers and cousins. They wanted to know why I was taking decisions what to do or not to do. Even I didn't know. It was done here. [He touches his stomach.] So I put together all 300 projects that I had helped develop -- some big successes, balanced by big fiascoes. The idea was to understand the reasons for these very unequal lives, and then predict the reaction of our customers.

alessi showroomShow me how it works.

I have two central parameters. [He sketches a grid.] One is called SMI. It means sensation, memory, and imagination, and tries to explore what people mean when they say, "Oh, what a beautiful object!" Beauty alone no longer expresses properly the relations of people with an object. You cannot use beauty when you describe a Starck project, for example. The second parameter is called CL, which means communication language. It measures the ability of a product to communicate something like status or values. A gold Rolex watch, for example, conveys wealth, while a Richard Sapper teakettle indicates cultural sensitivity. Each product can be scored 1 to 5 on each parameter. But we still had several products with the same scores, yet with very unequal lives. So I was obliged to add two more parameters: function and price.

Walk me through how some product would rate on this scale.

Let's take the Philippe Starck squeezer, the Juicy Salif. In the first phase of its life, communication was very strong: a 5. On the function scale, people thought it was an innovation; only later did they discover that it wasn't working so well! Give it a 4. Its price was about $60, for a score of 4, and its SMI, a 5, so its final score was 18. That meant it should sell about 100,000 pieces per year. A score of 12 is very risky -- 1,000 to 2,000 pieces. Since the Formula then was not very precise, you could be a bit wrong, and it could be a disaster. Twenty years later, in the Juicy Salif's second phase, its SMI is the same. [He writes down a 5.] Communication is less. [He writes a 4.] In terms of function, everybody knows it doesn't work, so that is a 2. Price is still reasonable, but we have introduced so many plastic pieces, it is not as impressive. Give it a 3. Today, it is a 14 -- about 50,000 units a year.

How accurate is the Formula?

If it is used on existing typologies, where Alessi has an existing product, it is very precise. If we face a new typology, where we don't have enough experience, like watches, we have to fine-tune it. It is a delicate activity to tune. On existing Alessi typologies, it cannot fail.

What part tends to trip you up?

On the function, we know what works. Same for price. Even in communication, we understand the effect of an object. But where we can misunderstand is in SMI. I can easily be wrong, confusing my personal taste with the taste of my customers.

Do you make the final decisions about products?

Yes. But it's very precious for me to understand the final score of the Formula. Not to manage by, but to understand the risk.

Does this formula work across cultures?

We do not see important differences among our core customers. They are not design victims, but they are surely not average customers. Their reactions are similar, both in Tokyo and Milan.

What has been the most successful product by all these measures?

Michael Graves's teakettle is number one. Starck's Juicy Salif squeezer is another. The first Alessandro Mendini corkscrew. The second Aldo Rossi coffeemaker. Ettore Sottsass's cutlery set. The Orientales plastic objects are also very strong.

If something doesn't measure up, do you eliminate it from the line?

Not necessarily. If I believe that it is an important product for Alessi, I continue. Sometimes I hide the results.

There has been a lot of talk recently that bad economic times are actually good for design. Are you buying it?

It is in part true. Throughout design history, there were some periods with a lot of social problems when design growth was fantastic. Take Finland at independence. When Finland needed to find its identity as a nation, it was a period of the best expression of Finnish design. Or right after the Second World War, Italy was all but destroyed, yet a lot of masterpieces were created. But it is also true that the 1980s were good for design, because the easy economic situation made it possible to experiment. Bad economic times are not a prerequisite.

How has the current economy affected Alessi?

I know what I have to do: Continue gardening my company exactly the way I have before. Not pushing too much for growth. Not looking for quantity of production because there are too many dangers there, not only for wine but for industry.

If you don't travel much anymore, where do you find inspiration?

I have a good nose to smell the true spirit of our times. Intuition comes from inside, not by watching what somebody has done or established trends. I prefer to stay home and listen to people. My horses. We talk. We exchange feelings, impressions, intuitions. It's nice.

Is MIT's Latest Solar 'Breakthrough' All Hype or a New Hope?

By Alex Hutchinson
Published on: August 1, 2008

MIT announced on Thursday afternoon a new method of splitting water into hydrogen and oxygen, predicting that it will unleash a "solar revolution." And they're partly right. The research, which appears in the new issue Science, has little to do with solar power as we usually think of it. But it has wide-reaching implications as a storage medium, making renewable but intermittent energy sources like the sun and wind more practical for everyday use.

The work, by MIT professor Daniel Nocera and his postdoc Matthew Kanan, follows several decades of work in a field sometimes known as "artificial photosynthesis," because it attempts to mimic one of nature's best tricks—storing energy in chemical bonds. In this case, energy from the sun can be stored in hydrogen when it is split from water; Nocera and Kanan have developed a catalyst for doing that more cheaply and efficiently.

HOW IT WORKS
Illustration of Dr. Nocera's "artificial photosynthesis" system.
The news is perfectly timed to catch a wave of enthusiasm for all things solar, as a number of different sun-powered technologies are finally approaching maturity as scalable and cost-effective options. Companies like First Solar have succeeded in bringing second-generation, silicon-free solar panels to the market at half the cost of traditional silicon panels, and the first in a wave of utility-scale plants for solar-thermal energy went online outside Las Vegas last year. MIT itself is so excited about solar power that it has announced no less than three solar revolutions in the last six weeks, starting with "the most cost-efficient solar-power system in the world" on June 18, and adding "a new approach to harnessing the sun's energy" on July 10.

But in many ways, today's announcement isn't the latest in a string of solar breakthroughs—it's actually a piece of good news for boosters of the much-maligned "hydrogen economy." With Honda ramping up production of its FCX Clarity fuel-cell car and GM testing a fleet of its Chevy Equinox prototype, it's clear that hydrogen still has plenty of potential as a fuel-storage medium. Nocera's catalyst raises hopes—if not hype—that everyone with a roof could someday have a simple way of making hydrogen from water.

How It Works
Water is H2O—two hydrogen atoms and an oxygen atom—and scientists have known for two centuries how to apply a jolt of electricity to split it into hydrogen and oxygen, a process called electrolysis. What Nocera's scheme promises is a way of doing what existing commercial electrolyzers do, but much more simply and efficiently.

"Conceptually, it's the same thing," Nocera says. "But instead of feeding electrons into a hermetically sealed box filled with a concentrated base, we can feed them to an electrode sitting in a simple glass of water, at room temperature and pressure, with neutral pH." That simple setup makes it easy to build, operate and maintain.

Just as importantly, the catalyst identified by Nocera and Kanan uses cheap and abundant materials—cobalt and phosphorous—instead of the rare and expensive metals used as catalysts in existing systems. That's crucial, since the question isn't whether we can split water (we already know we can), but whether we can do it cheaply enough to install a system in every house.

The new catalyst actually facilitates the production of the oxygen byproduct. That's half the battle—a separate catalyst for hydrogen production is the other half—but it's crucial to making the whole process work. "You can't complete the circuit unless both parts are working," explains Tom Mallouk, a Penn State chemistry professor pursuing similar goals.

The search for a cheap, efficient oxygen catalyst has lagged far behind the development of hydrogen catalysts, according to University of California Irvine professor Alan Heyduk, who worked with Nocera as a graduate student but wasn't involved in the current research. "This has been a bit of a holy grail," he says.

Memristor

The memristor, a microscopic component that can "remember" electrical states even when turned off. It's expected to be far cheaper and faster than flash storage. A theoretical concept since 1971, it has now been built in labs and is already starting to revolutionize everything we know about computing, possibly making flash memory, RAM, and even hard drives obsolete within a decade.

Steamy Dishes


This looks like it's good for dishes, but pots and pans are still going to have to be done by hand...

Dishwashing techniques are undergoing massive consideration for two factors, one the size and placement of the dishwashers and two, the consumption of energy and water. The Eco-Friendly Steam Dishwasher addresses both these issues in quite a fascinating way. As for the size and placement, it’s a counter-top version good enough for a small family or singletons. So no more bending to load the wash. For the Eco-friendly part hit the link.

As the title suggests, this dishwasher uses pressurized steam to dislodge food particles on dishes and sanitize them. A hearty rinse after the cleaning process gives you squeaky clean dishes!

Now for the Eco-friendly part. Since no detergents are used, there is less of “ozone depleting solvents” going around. The water used in the steam and rinsing is collected in the recycling bay and using “Membrane Technology” (read more info on this here), the grime and food particles are separated from the water. The clean water is recycled to be used again for the next wash.

Contaminated water, too harsh for reusing is discarded via an outlet and only then is a fresh load of water consumed.

ILoveSketching: The future of design drawing?



This is awesome!

A 3D curve sketching system that captures some of the affordances of pen and paper for professional designers, allowing them to iterate directly on concept 3D curve models. The system coherently integrates existing techniques of sketch-based interaction with a number of novel and enhanced features. Novel contributions of the system include automatic view rotation to improve curve sketchability, an axis widget for sketch surface selection, and implicitly inferred changes between sketching techniques. We also improve on a number of existing ideas such as a virtual sketchbook, simplified 2D and 3D view navigation, multi-stroke NURBS curve creation, and a cohesive gesture vocabulary.

Implantable sensor simplifies blood pressure readings

The tiny blood pressure sensor

The tiny blood pressure sensor


High blood pressure is a major health risk and as the world’s population ages, that risk continues to climb. It can be a trial of patience for doctors and for sufferers, whose blood pressure often has to be consistently monitored over a long time until it can be regulated. A new sensor being developed by Fraunhofer-Gesellschaft researchers together with the “Hyper-IMS” (Intravascular Monitoring System for Hypertension Patients) company aims to make this monitoring easier. To monitor blood pressure patients have traditionally had to wear a small case containing a blood pressure meter close to their body. An inflatable sleeve on their arm records their blood pressure values, for which it is regularly pumped up and deflated. This can prove to be a bit of a hassle, particularly at night but now the whole process is now due to become significantly simpler thanks to a tiny implant that can achieve the same result.

With the new method a tiny pressure sensor, which has a diameter of about 1 millimeter is placed directly into the femoral artery in the groin and measures the patient’s blood pressure 30 times per second. The sensor is connected via a flexible micro-cable to a transponder unit, which is likewise implanted in the groin under the skin. This unit digitizes and encodes the data coming from the micro-sensor and transmits them to an external reading device that patients can wear like a cell phone on their belt. From there, the readings can be forwarded to a monitoring station and analyzed by the doctor. Because the researchers use special components in CMOS technology, the system requires little energy. The micro-implants can be supplied with electricity wirelessly via coils.

The researchers say implantable pressure sensors are also suitable for other applications, such as monitoring patients suffering from cardiac insufficiency. The first clinical trials are now underway.

Algae used to create a quick-charge, lightweight battery

Algae blooms are unpleasant and unpredictable phenomena that arise quickly and strike seas and oceans often causing serious problems to local ecosystems. But in an effort to try and find a use for such algae, a research team from Uppsala University, Sweden, has recently managed to design a record-breaking "green" lightweight battery that is incredibly easy to produce and could just even out the environmental consequences of these blooms.

As the authors explained in a paper published in the latest edition of the journal Nano Letters, the key idea behind the design of this peculiar battery was to exploit the unique cellulose structure of the Cladophora algae, which is characterized by a very large surface area.

By coating this structure with an extremely thin (only 50 nanometers) layer of conducting polymer, the team managed to produce a battery that weighs very little and can be fully charged in as little time as 11.3 seconds at 320 mA, still retaining good cycling capabilities.

The battery charge, in fact, decreases by only six percent after 100 charge/discharge cycles. Prof. Maria Strømme, who led the research efforts, pointed out that this figure was for a completely non-optimized packaging. The team is now working on this specific aspect and has already achieved over 1000 charge cycles.

This is a major step forward for conductive polymer batteries, which are known to be more environmentally friendly than most metal containing electrode materials, but had shown very poor cycling stability so far, making them unfit for commercial applications.

But due to its characteristics, the Cladophora-polypyrrole battery could actually be mass-produced, particularly for applications where cost and/or weight are an issue, opening a plethora of new possibilities for low-cost electronics.

"We are talking about a battery that mainly consists of paper and salt water and that can theoretically be made in your own kitchen (if you have a strong mixer) without the major energy input needed to create today’s batteries," Prof. Strømme told us in an email.

"With the technique fully developed, I believe that we may see applications that we cannot really dream of today. Try to imagine what you can create when a battery can be integrated into wall papers, clothes, the packages of your medicines, etc."

Don't expect to find these batteries powering an iPhone or your next electric car anytime soon, though, as one of the major drawbacks of cellulose-polymer battery technology appears to be the relatively low storage capabilities when compared to metal electrode technology — approx. 25 Wh/kg for the team's design against Lithium-ion's 100-160 Wh/kg.

Environmentally Friendly Remote Control Light Bulbs


Published on August 14, 2009 |

Sharp Corporation will introduce into the Japanese market nine models of LED light bulbs that are extremely environmental when compared to existing bulbs.

For instance they have high energy efficiency, a long service life (40,000 hours), and are free of hazardous mercury. In addition, when hooked up to a circuit, you can adjust the colour temperature of all of them with a wireless remote control.

No news yet on when they’ll be available outside of Japan but, if they’re a success, I’m sure it won’t be too long.

Japan Harnesses Energy from Commuters’ Footsteps

December 23, 2008

Two of Tokyo’s biggest train stations have begun experimenting with harnessing the energy generated by the footsteps of millions of commuters who pass through each and every day. Special floor tiles installed in front of the ticket turnstiles trigger a small vibration that can be stored as energy every time a passenger steps on them.

From The Telegraph:

Multiplied many times over by the 400,000 people who use Tokyo Station on an average day, according to East Japan Railway, and there is sufficient energy to light up electronic signboards.

“We are just testing the system at the moment to examine its full potential,” said Takuya Ikeba, a spokesman for JR East, adding that the tiles are constructed of layers of rubber sheeting, to absorb the vibrations, and ceramic.

Deeply dependent on imported fuel to power its industries, Japanese companies are at the forefront of research into clean and reuseable energy sources.

The “Power Generation Floor” at Shibuya Station on the other side of Tokyo can generate an even more significant amount of power considering that 2.4 million people pass through it each day. The power generated by the tiles, made by Soundpower Corp., can be stored in capacitors and channeled to the areas of the station in need of power, including the lighting system and ticket gates.

It’s awesome to see this technology get tested on a large scale. It only makes sense to harvest clean, emissions-free energy however we can, and with the millions of people that pass over busy stations like this all over the world, it really has potential to do a lot of good.

Waking Up with a Pleasant Experience Via Philips HF3490 Wake-up Light cum iPod Dock

You need an alarm clock to wake you up every morning but you might not like the feeling of having to defuse a “bomb” every day which makes you feel stressful and creates an unpleasant start to the day. Natural sounds such as bird or insect chirping and a gentle sunrise gradually warming your back will be a nicer way to wake you up and cheer you up for the day. Unless you stay in the countryside, you might not have this wonderful experience as you are surrounded by a concrete jungle. To city dwellers, the Philips HF3490 wake-up light could be something to lay their hands on.



The new Philips HF3490 will wake you up in a more “natural” and pleasant way by gradually illuminating your space with brighter light. When the surrounding environment turns brighter, the human body will be able to sense the changes and direct the signal to the brain to wake the person up.

Adjustable Light Bulb

Light Play with DL-L60AV

Do you ever get tired of the same shade of light in your bedroom or living room? It would be easier to change a light bulb to create a new concept or feeling than to repaint the room. The DL-L60AV from Sharp features an adjustable color function which allows homeowners to adjust the light in seven subtle shades of white to introduce warm or cool glows. This is a pioneering technology which has generated some excitement in the industry as it gives users the freedom to play around with the lighting in their house with minimum physical disruption.

Stanford University's EyePoint: Web Surfing With Eye Gaze

August 20, 2007 (Computerworld) -- Increased computing power doesn't just make for better graphics; it opens up new ways to interact with computers. Take, for example, the EyePoint system developed by Stanford University doctoral researcher Manu Kumar.

EyePoint uses a four-step process that incorporates a user's hands and eyes to increase accuracy and eliminate the false positives that come from using eye movements alone. Plus, the technique brings a more natural way of interaction to a broader band of users.

"Using gaze-based interaction techniques makes the system appear to be more intelligent and intuitive to use," says Kumar. "Several users have reported that it often felt like the system was reading their mind."

Here's how it works: While looking at a screen, the user presses a hot key on the keyboard, magnifying the area being viewed. The user then looks at the link within the enlarged area and releases the hot key, thereby activating the link.

Eye tracking, which has been around for decades, typically uses infrared devices embedded into a headset or a monitor frame. The devices track the centers of the user's pupils and then calculate which part of the screen the user is viewing.

This method, however, has been plagued by errors, limiting its use primarily to people with disabilities that prevent using a keyboard and mouse.

Eye trackers are accurate to about 1 degree of visual angle. When looking at a 1,280-by-1,024-pixel, 96-dpi screen at a distance of 20 inches, this equates to a 33-pixel spread in any direction from where the user is looking. That's not accurate enough to pinpoint a link.

"What is really exciting is that the processing power of today's computers is completely changing the kinds of things we can use for computer interfaces," says Ted Selker, associate professor at the MIT Media and Arts Technology Laboratory and director of the Context Aware Computing Lab. "Things like eye tracking are using channels of communication that literally were unavailable to interface designers even five years ago."

"[Kumar's] approach -- using eye movement in a subtle, lightweight way, rather than as a direct mouse substitute -- is exactly the right way to go," says Robert Jacob, a professor of computer science at Tufts University in Medford, Mass.

Selker says eye tracking might become a standard computer interface within the next five years. For now, the primary obstacle is the high cost of eye-tracking hardware, although mass adoption of the technology would drive those costs down.
