Kites fly in jet stream to generate electricity
Mr Shepard’s flying generator looks like a cross between a kite and a helicopter. It has four rotors at the points of an H-shaped frame that is tethered to the ground by a long cable. The rotors act like the surface of a kite, providing the lift needed to keep the platform in the air. As they do so, they also turn dynamos that generate electricity. This power is transmitted to the ground through aluminium cables. Should there be a lull in the wind, the dynamos can be used in reverse as electric motors, to keep the generator airborne.Here's another interesting proposal: Meanwhile, Wubbo Ockels of the Delft University of Technology in the Netherlands has been developing another approach to airborne wind generation at lower altitude, with backing from Royal Dutch Shell and Nederlandse Gasunie, a natural-gas company. Dr Ockels’s idea is that a kite (without rotor blades) be launched from a ground station, turning a generator as it rises to an altitude of several hundred metres. When it reaches its full height, it alters its shape to catch less wind, and can thus be reeled back in using much less power than it produced when it was being paid out.

Nanogenerator Provides Continuous Electrical Power
Device harvests energy from the environment to provide direct current
Atlanta (April 5, 2007) — Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.
Based on arrays of vertically-aligned zinc oxide nanowires that move inside a novel “zig-zag” plate electrode, the nanogenerators could provide a new way to power nanoscale devices without batteries or other external power sources. “This is a major step toward a portable, adaptable and cost-effective technology for powering nanoscale devices,” said Zhong Lin Wang, Regents’ Professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. “There has been a lot of interest in making nanodevices, but we have tended not to think about how to power them. Our nanogenerator allows us to harvest or recycle energy from many sources to power these devices.” Details of the nanogenerator are reported in the April 6 issue of the journal Science. The research was sponsored by the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation (NSF), and the Emory-Georgia Tech Center of Cancer Nanotechnology Excellence. The nanogenerators take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed. Fabrication begins with growing an array of vertically-aligned nanowires approximately a half-micron apart on gallium arsenide, sapphire or a flexible polymer substrate. A layer of zinc oxide is grown on top of substrate to collect the current. The researchers also fabricate silicon “zig-zag” electrodes, which contain thousands of nanometer-scale tips made conductive by a platinum coating.
The electrode is then lowered on top of the nanowire array, leaving just enough space so that a significant number of the nanowires are free to flex within the gaps created by the tips. Moved by mechanical energy such as waves or vibration, the nanowires periodically contact the tips, transferring their electrical charges. By capturing the tiny amounts of current produced by hundreds of nanowires kept in motion, the generators produce a direct current output in the nano-Ampere range. Wang and his group members Xudong Wang, Jinhui Song and Jin Liu expect that with optimization, their nanogenerator could produce as much as 4 watts per cubic centimeter – based on a calculation for a single nanowire. That would be enough to power a broad range of nanometer-scale defense, environmental and biomedical applications, including biosensors implanted in the body, environmental monitors – and even nanoscale robots. Nearly a year ago, in the April 14, 2006 issue of the journal Science, Wang’s research team announced the concept behind the nanogenerators. At that time, the nanogenerator could harvest power from just one nanowire at a time by dragging the tip of an atomic force microscope (AFM) over it. Made of platinum-coated silicon, the tip served as a Schottky barrier, helping accumulate and preserve the electrical charge as the nanowire flexed – and ensuring that the current flowed in one direction. With its multiple conducting tips similar to those of an AFM, the new zig-zag electrode serves as a Schottky barrier to hundreds or thousands of wires simultaneously, harvesting energy from the nanowire arrays. “Producing the top electrode as a single assembly sets the stage for scaling up this technology,” Wang said. “We can now see the steps involved in moving forward to a device that can power real nanometer-scale applications.”

Samsung's Mobile WiMax MITs devices go live in S.Korea
from Engadget by Thomas Ricker
As if you weren't already feeling cheated by your data plan, Samsung comes along and launches a few Mobile WiMax MITs (Mobile Intelligent Terminal) devices in S.Korea: their SPH-M8100 WinMo 6.0 cellphone and SPH-P9000 (pictured) all-out convergence thingamajig. That's right, 12Mbps or about 2-3 Mbps when traveling up 120-KPH (75-MPH). While the Mobile WiMax (or WiBro as it's hailed in its Korean home) service isn't country-wide yet, Korea Telecom's offering does cover the 10M+ people scooting about Seoul and its southern suburbs including 17 universities and 4 subway lines. How S.Korea pulled a 19 ranking on the technology superpower list still has us scratching our heads.

'You Who?' - Trust in Web 2.0
Posted by centernetworks 04/12/2007
At the end of 2006, Time magazine decided that its person of the year was 'You'. Yes, You. All the You's that create and rate content on heavy hitting sites such as MySpace, Wikipedia and YouTube. The reason behind this is that a shift has happened where content isn't generated or rated by experts anymore. Instead it's by everyday folk like you. This is further back up by a recent Revolution survey showed that within the 16-44 age group: 48% have been to a blog site 26% have created their own blog 74% have rated or reviewed products, content or services You and user generated content User generated content is one of the key foundations of Web 2.0. (For those of you that haven't heard the hype, Web 2.0 is a term created to define the second phase of the Internet following the dot com crash.) One of the key foundations of Web 2.0 is new functionality that changes content within a page based on what a user does. But let's get back to You - after all, this article is all about You! First of all who are You and more importantly how can I trust You? In fact the same question applies to me from your perspective. Who am I and more importantly how do you know that anything I write is worth the HTML it's coded in? Currently there's an avalanche of new content being written on the web. The problem is that it becomes very hard to work out whether the source is accurate and whether the people looking at it know anything at all. So is there anything from web 1.0 that can help us? Trust in Web 1.0 In the old days (read the 1990's) trust was mostly to do with ecommerce. How could you trust a website enough to either give your personal details or credit card numbers to buy something? A whole set of standards was subsequently developed to ensure users trusted your website. Some of the key points were to: Prove there's a real organisation behind your site (e.g. contact details, about us section) Explain what you're going to do with sensitive information Provide third party evidence of your credibility (e.g. testimonials) Have a professional design Regularly update the site so it looks alive and fresh Avoid all errors of any kind But are these guidelines still relevant? Do we need any other guidelines? The problem with user generated content In Web 2.0 the issue of trust has moved away from the people that run the site and is now starting to focus more on the people that populate it. People are engaging with each other at a one to one level in so many ways, such as: Business (e.g. eBay) Pleasure (e.g. MySpace, YouTube, Secondlife) Information (e.g. Wikipedia, Digg) Classifieds (e.g. Craigslist, Gumtree) The issue of 'Can I trust this site?' still exists, but the new issue, 'Can I trust the people on it?' is now equally important. The main difference now is that content is being generated by anyone and then being rated by anyone. How can you be sure that what other users write is true? For example, there's been some controversy about the reliability of articles on Wikipedia, the online encyclopaedia. Even more controversy occurred when a guy solicited dates from other men pretending to be a woman on the personals section of Craigslist. He then published all their personal details on the web! Yet another example is online restaurant guides. How can you trust someone's review when you don't know their tastes? Is the reviewer someone who goes out solely for tasty food or someone who goes out for the atmosphere/occasion? So, how do we resolve these issues? Trust 2.0: Ensuring trust in Web 2.0 To ensure site visitors continue to trust your site, you need to ensure users are who they say they are. Ways you can achieve this when users are registering include: E-mail an activation link Send a text message with an activation code Send the activation code to a home or business address You can also: Only allow site visitors access to content/functionality if recommended by a registered user (LinkedIn, the online career network, does this) Show people you know their IP address when they're logged in Collect users' credit card details If site visitors know you've validated the credibility of users creating content, they're far more likely to trust that content. Other ways of increasing trust of user generated content, and enhance the credibility of users, include: Make users' profiles publicly available to everyone in the community (the profile can include tastes, expertise or experience, for example) Allow users to rate a person for their content, services or products (eBay does this) Set up a reference system to highlight respected contributors (Amazon now gives out 'badges' to reviewers, where they get tagged with 'real name' (if the site can verify that it's their real name) or 'top 500 reviewer' (if the site feels the person has given good reviews)) Have real time face-to-face interaction (e.g. Skype on eBay, Winebit) You won't of course need (or want) to implement all of these techniques - think about what your site is trying to achieve and the needs of your audience. You should then be able to come up with an appropriate trust strategy. Conclusion Guidelines for ensuring trust borne out of Web 1.0 still remain very valid in today's Internet. After all, web users need to be able to trust your website and the content that you've put on there. They also need to trust content generated by other users - follow some of the advice in this article to ensure this! This article was written by Mark Halabi. He's crazy about web usability and accessibility - so crazy that he's head of client services at usability and accessibility consultancy, Webcredible. He's extremely good at running focus groups and carrying out card sorting sessions.

NYTimes: Corbis - A Photo Trove, a Mounting Challenge
In some sense, the iconic photograph of Rosa Parks recreating her quiet act of rebellion on a bus in Montgomery, Ala., belongs to every American. But as a practical matter, it belongs to Bill Gates.
Anyone wanting to use that image in a book or on a Web site must first license it from Corbis, a corporation founded and owned by Mr. Gates, who is better known for starting Microsoft. The photo is among the 11 million prints and negatives in the legendary Bettmann archive, which Corbis bought in 1995.
Since that first purchase, Corbis has spent tens of millions of dollars acquiring image collections and other companies, hired more than 1,000 people and set up two dozen offices worldwide. Although Corbis says it brings in some $250 million a year in sales, it has yet to turn a profit.
Now the company is shuffling its top executives as it takes on new challenges, building up a business in rights management and plotting its response to the rise of low-cost online photo services that threaten to undermine its lucrative stock photo sales.
The company plans to announce Tuesday that Gary Shenk, the president, is being made chief executive as well. Mr. Shenk, 36, is an expert in rights licensing who has risen rapidly through the Corbis ranks since he was hired in 2003 from Universal Studios, where he started a small licensing unit.
Steve Davis, 49, the departing chief executive, will continue as a senior adviser after 10 years of running the company.
The move into rights clearance, which involves sorting out the questions of who owns what material and how much they should be paid for its use, is a departure from the original vision for the company.
Mr. Gates started Corbis in 1989 with the idea that people would someday decorate their homes with a revolving display of digital artwork — interspersing, say, Cecil Stoughton’s shot of John F. Kennedy Jr. playing under the desk in the Oval Office with photos of their own families at play.
That is not how things have worked out. But meanwhile Corbis has built up a formidable stash of historical photos, including those in the Bettmann Archive. In 1999, Corbis acquired the licensing rights to the Sygma collection in France, and two years ago it did the same with a German stock image company called Zefa. It licenses those images for an average of about $250 apiece.
Corbis also owns digital reproduction rights for art from the Hermitage Museum in St. Petersburg, Russia, the Philadelphia Museum of Art and the National Gallery in London.
In all, Corbis represents or owns the rights to more than 100 million images, including some of the most famous photographs ever — Arthur Sasse’s photo of Einstein sticking his tongue out and Marilyn Monroe on the subway grate. And Corbis handles the licensing of millions of other images on behalf of thousands of photographers.
The archival photos bring in about half of Corbis’s sales, but the company also has a stable of professional photographers who generate stock photos for advertising and media clients — images of children on playgrounds, people sitting in business meetings and men in khakis swinging golf clubs.
Over the past few years, Corbis has moved beyond newspaper and magazine clients to pursue advertising and graphic design agencies, as well as corporate marketing departments, which are turning increasingly to high-quality stock photography rather than doing their own expensive photo shoots.
Those customers are also buying from Corbis’s growing library of 30,000 short video clips — mostly generic scenes of, say, people shopping or running down the beach.
What Corbis did not foresee was the rise of so-called microstock agencies like Fotolia and iStockPhoto. These sites take advantage of the phenomenon known as crowdsourcing, or turning to the online masses for free or low-cost submissions. Thousands of amateur and semiprofessional photographers armed with high-quality digital cameras and a copy of Photoshop contribute photographs to microstock sites, which often charge $1 to $5 an image.
Although the microstock business still represents a small fraction of the $2 billion market for stock photos, analysts say it is possible that low micropayment prices could take business away from the higher-priced images Corbis relies on for the bulk of its revenues.
“Think about how visual the world is,” said Barbara Coffey, a senior research analyst at Kaufman Brothers in New York who follows the stock photography market. “We have pictures on our cellphones. If I can get a reasonably clear picture and the rights are cleared and I pay $2 for it, then why would I pay Corbis $200?”
The rise of the microstock companies has been of particular concern to Corbis. For all its new lines of business, the company still gets some 88 percent of its revenues from image licenses, yet commands only about 11 percent of that market. Getty Images dominates the market with a 40 percent share.
Getty, which has grown quickly since its start in 1995 with the backing of its wealthy co-founder, Mark Getty, has a foothold in microstock thanks to iStockPhoto, which it bought last year for $50 million.
Mr. Shenk said Corbis would announce its plans for the microstock business sometime this quarter. As for the question of how a high-end company enters that business without cannibalizing its more expensive products, Mr. Shenk said the idea was to find a new kind of customer, people who would never envision buying pictures from a Corbis or Getty.
In that vein, Mr. Shenk said Corbis would make its service as easy to use as the iTunes store of Apple and hinted that Corbis would also be following the crowdsourcing model.
“More interesting and innovative things are happening on the pages of Flickr these days than on Corbis and Getty,” said Mr. Shenk, referring to the photo-sharing site owned by Yahoo. “If we can use this type of opportunity to find the next great group of Corbis photographers, that also makes it a great opportunity for us.”
Corbis is also betting heavily on its Creative Resources division, which includes rights services and recorded 44 percent growth in revenue last year, to $30.1 million.
Mr. Shenk, who will take over from Mr. Davis at the end of June, is most likely the biggest reason for that growth. When Mr. Shenk left Universal for Corbis in 2003, he took five people and an impressive Rolodex with him. Now nearly 30 Corbis employees work in rights clearance, in offices in Los Angeles, New York, Europe and Asia.
Mr. Shenk, a Hollywood veteran who is an expert in what he calls “new ways to sell media,” said he believed Corbis was offering something unique in building a worldwide network of rights experts. The business of rights clearance, he said, is often a matter of knowing whom to call, and the idea is to make Corbis the first place that comes to mind when, say, an advertising agency is trying to clear the rights to use an image, video clip, or song.
Such was the case when the band U2 made its most recent video, for “Window in the Skies,” which braided together some 100 clips of old stars like Ella Fitzgerald and Frank Sinatra, synched to the new song’s music and lyrics. Corbis helped the band’s production company negotiate a thicket of publicity rights.
Roughly one-third of Corbis’s 1,100 employees are in downtown Seattle, in an old bank building well suited to the company’s hip self-image. The vast, open, two-story space has retained several enormous vaults that once held gold bars and now serve as photocopy and office supply rooms. Conference rooms are named after famous photographers, and copies of their work cover many of the walls.
The Corbis photographs themselves are not stored in Seattle, except digitally on the computers there. And those digital images constitute only a small fraction of Corbis’s holdings. Of the 50 million items in the Sygma collection, just 800,000 have been digitized.
The prints and negatives from Otto L. Bettmann’s archive, as well as those from a few smaller collections, are kept 220 feet underground in a former limestone mine in rural Pennsylvania. In February, Corbis announced that it would be storing the Sygma collection in a preservation facility near Paris.
As ventures go, Corbis represents a small investment for Mr. Gates. He pays for large expenditures, and the company uses its revenues to cover smaller projects within the firm.
Mr. Gates’s involvement in the company is minimal. He spends only two to three hours each month meeting with Corbis management. Yet it is clear that he makes the big decisions. He has no interest, for example, in treating the undigitized portions of the image collections like one of his charities by, say, donating them to a public entity.
Despite the hands-off approach, Mr. Gates is apparently never far from the minds of Corbis employees. Mr. Shenk is in the process of relocating to Seattle from Los Angeles, and his sparsely decorated office in Seattle is evidence of the commuter life he has been leading. The only work of art in evidence one recent afternoon was on Mr. Shenk’s whiteboard, where a colleague had drawn the unmistakable likeness of Mr. Gates, peering out from behind his glasses.
“Keep up the good work, Shenk,” Mr. Gates says. “Or I’ll kill you.”

ETech: Big Company Hacks at Yahoo
Earlier today Yahoo launched a Yahoo Mail API. Recently we analyzed the current API and Mashup trends on the Web and noted that Yahoo is one of the big companies most active in this area. Also not long ago we profiled Yahoo! Pipes - a new tool that, we argued, treats the web as the database. We later expanded these ideas in our post entitled When Sites become Web Services. The major theme running through all these posts is that the Web is turning into a database exposed via APIs. Web giants like Google, Amazon and Yahoo! have been tapping into the large web development community, by exposing their services via APIs.
Here at ETech, Chad Dickerson, Sr. Director of the Yahoo! Developer Network, gave a session about Yahoo's experience in engaging its own engineers to utilize Yahoo! APIs in creative ways.
According to Programmable Web, Yahoo! currently has over twenty APIs. These APIs, along with additional development resources, are available on the Yahoo! Developer Network. There is plenty to dive into - from the better known Flickr, Chat and Map APIs to online Ad Management and Web Site Analytic services. The latest edition is of course the Mail API. These APIs provide a big opportunity to get creative. So to facilitate the exploration and to encourage the discovery of new mashups - and possibly products - Yahoo! management decided to call on their own engineers to play around. Or in Yahoo's lingo, to hack. The official Yahoo! Hacks program calls for self-directed projects by Y! engineers, which do not need to be approved by anyone in advance.
Yahoo's method to the madness
The self-organization is exciting and powerful, but to get results there needs to be control. Yahoo's answer is "Hack days", where developers can showcase their creations to their colleagues. Here are the rules:
- Build something in 24 hours;
- No Power Points;
- Present in 90 seconds;
- No prior review, anything goes.
These rules encourage small teams to do what they love, letting people create what they want and, occasionally, letting the bizarre out.
In addition to internal hacking, Yahoo! opened up the program to a group of external hackers and invited them in September to the Yahoo! campus for a full day of hacking. According to Yahoo! the day turned out to be a "mega success".
Examples of Hacks
What goes on during the internal hack days is kind of a secret. Chad shared an example of a rather controversial hack. It was a web site built in 'Hot or Not' style, showing pictures of Yahoo! employees and letting people choose who they think is the boss of who. The application kept track of all "mistakes" and then displayed a chart for who should be promoted or demoted. Apparently calls from the Human Resources department followed.
Another hack was a purse that would take a photo after you walk every 100 steps and then use the Flickr API to upload it online. Yet another interesting hack was created by a group of developers, who turned an old TV into a widget display. One of the widgets connected to the internet and showed (you guessed it) the current weather.
Conclusion
At first, this 'hack' culture might seem to be somewhat chaotic and wasteful. It is in a way, but there is also a big potential gain. By using self-organization, Yahoo! bets that while a lot of these hacks will be mildly interesting - there may be a handful that are profound and game changing for the company. Since there are so many APIs, possibilities are almost endless.
Yahoo! hacks is a great program that could lead to breakthrough ideas and products. The key question is how to add a process on top of this dynamic and fluid process, that drives productization and monetization of the best prototypes. Presumably, the really interesting solutions get noticed and get on the management radar screen. It is not clear if Yahoo! is doing this already, but it would seem that an nternal, Digg-like system where all Yahoo! employees would be able to rate creations, could be also helpful. We will see over the next year or so how Yahoo! executes this project, but the potential is definitely there.
Amazon enters PPA contextual market
With Amazon's program, you just add code to your page and Amazon takes care of the rest. You are not technically "supporting" a specific product; Amazon figures out what to show. And the links are based on the words already within your content. So you might be wondering how this differs from the announcement from Google last week about their PPA offering. Pretty simple actually. With Google's PPA program, you add content to your page pushing the links. I believe Google's setup is more along the lines of the Payperpost model.
I have placed the code within some of the tutorials on HTMLCenter but it is not showing links yet (links are now showing). The Context Links setup is very easy and flexible... here is a screenshot:
Will these contextual (PPA) ads work long-term? I know they have worked for me for a couple of years and so far I have not had lots of pushback on HTMLCenter. You might be wondering if I will add them to CN... not yet, still working on the optimal setup for ads for CN.
It is interesting to think about how ads have evolved. We started outside the content, then moved inside with the 300 boxes and so forth and now we are linking the internal story content. Not sure we can go any much deeper than that!

Why Google Isn't Stealing Newspaper Content
Contributed by Mike (TechDirt) Monday, April 9th, 2007 @ 6:45AM
from the make-it-stop dept
This is just getting ridiculous. Google may have signaled its willingness to pay up with its deal with AFP, and now it seems that newspaper publishers are interested in taking them up on the offer. OJR reports that Sam Zell, who is in the process of buying the Tribune Company, has lashed out at publishers for letting Google "steal" their content: "If all the newspapers in America did not allow Google to steal their content for nothing, what would Google do, and how profitable would Google be?" This sounds quite similar to columnist David Lazarus' "plan" to save the newspaper industry. Unfortunately, they've got the situation completely backwards. Google is not "stealing" content. They're also not making their money off of other's content. What they're doing is making that content a lot more valuable by making it much easier to find. Google isn't making money on the content -- but on driving more people to that content (and on the news side, they don't make any money directly, since they don't run ads on Google News). It's bizarre that this is so difficult for those in the publishing industry to understand. You don't yell at the phone book for "making money" off of your contact information. You don't yell at tour books for "making money" off of other people's locations. You recognize that they make money by being a guide or a directory -- just like Google. Either way, it doesn't bode well that the guy who's taking over the Tribune Company doesn't seem to have the slightest clue how Google works or how it's helping, not hurting, the business he's in the process of buying.
