Auto Designers Cater To China, the New Giant Read More http://www.wired.com/autopia/2010/02/automotive-design-for-china/?utm_source=feedburner&utm_me

Western automakers have started designing cars specifically for the huge Chinese market, and we don’t mean just meeting tighter pollution and fuel-efficiency standards.

The new cars and concepts have exterior contours that comport to Chinese ideas of balance, with interior colors and fabrics designed to signify status and evoke respect. The controls for entertainment and climate systems might even be moving to the back seat, because truly wealthy people don’t drive, they have drivers.

Thirty years ago, the People’s Republic of China was an automotive backwater. Today it’s the biggest market in the world, having just eclipsed the United States. So, its consumers are demanding the best from automotive designers.

The explosive growth of the Chinese market, where consumers bought 17 million new cars last year compared to about 10 million in the United States, has been a bright light in an otherwise dark time for the auto industry. As the traditional markets of North America, Europe and Japan stagnate or decline, automakers have seen their sales in China double and double again.

“This is clearly the market of the future,” says Freidhelm Engler, General Motors director of design in China. “It’s not going to slow down.”

That has automakers taking a fresh look at how they design cars for the Chinese market. Although Western designs have proven immensely popular in China, global car companies were slow to account for Chinese tastes and preferences. More often than not, automakers made a few small tweaks to the cars they sold in the West and shipped them over.

“Ten to 15 years ago, companies brought existing designs or even dated designs to the Chinese market,” says Chelsia Lau, chief designer at Ford Asia-Pacific. “Consumers in China are no longer satisfied to accept designs directly copied from overseas and are now far more discriminating and demanding.”
First, a quick history lesson on how we got here.

A little more than a generation ago, China’s GDP per capita was just over $100. As a command economy with a decrepit transportation network, it offered little incentive for Western automakers to sell there. Not that it mattered, because the governments of China and the United States didn’t want them to, anyway.

That started to change in the 1970s as the two countries normalized relations, and Deng Xiaoping (Mao Zedong’s successor) created economic zones where foreign manufacturers could build. Automakers rushed to establish joint ventures with Chinese companies and start selling cars.

As China’s economy grew, so did demand for cars. As money poured in, the increasingly wealthy population began to buy a lot of cars. China’s increasingly affluent middle class is larger than the entire U.S. population, and the Chinese market has been the fastest-growing for several years.

Last year, it surpassed the United States to become the largest automotive market in the world. It was a long-awaited marker that came unexpectedly soon after the economic recession brought U.S. car sales to a screeching halt.

Now vehicle designers in China face unique challenges and opportunities. They are being given control over large organizations and an increasingly influential voice.

Ford started building cars in China in 2003 and moved its Asia-Pacific offices from Bangkok to Shanghai last year. GM has increased its design staff in China from 80 in 2005 to 1,700.

Both are playing catch-up to Volkswagen, which was among the first companies to enter China and last year managed to sell more cars than any other automaker, Chinese or otherwise.

The challenges facing these designers is daunting. A vast cultural gulf separates China from the U.S. and Europe, requiring different design considerations and a new consumer portrait. Brands marketed in China are largely unencumbered by their legacies abroad, allowing for radical redefinitions. Buick, for example, known in the United States as a car for old people, is in China popular among wealthy businessmen.

“Just imagine, for a moment, a Buick Regal,” says Engler, “A buyer could be around 30…. This is different from a consumer who is 15-20 years older and is in a different league.”

Some design considerations are wholly different in China, where a car’s most important role is often to serve as an indicator of wealth and power. Take a look at the Buick Business concept pictured at right. See the cut of the headlights, meant to mimic traditional Chinese liuli glass? See the chrome trim? Chrome is huge in China. See the connecting line between head and taillights and how it drops at the rear seats to emphasize the passenger and increase visibility?

Inside, the back seat envelops the passenger “like a clam,” Engler says, in the same manner as an emperor’s throne. Interior coloring is nearly monotone from the rear passenger’s perspective in accordance with Chinese expectations of a car. Notice the deep purple color. GM says was “chosen to elicit the right level of attention and respect” and named it euphemistically after a rare and slow-growing Chinese tree, It was designed, Engler says, to look like a smooth fabric blowing in the wind.

“It has a nice gesture to it, something which is very Chinese,” he adds. Try finding that look in an American GM product.

Describing the Shanghai office’s influence on the update of the modest Ford Fiesta, head designer Chelsia Lau uses words like “sleek” and “elegant,” phrases that might be a stretch to a potential American buyer. But in China, where families routinely pool their money to buy a car, it makes sense to make a car sound as upscale as possible.

In China, the focus of control shifts from the driver’s seat to the passenger or rear seat, where the owner might prefer to sit, as it indicates higher status. Because the rear seat is the position of power, that’s where you’ll find controls for the radio, heat, sunroof and so forth. In the United States, of course, the driver controls everything.

The same principle requires a new focus on the entire car. Designers place special emphasis on exterior styling, which is held to higher standard than in the West. Loosely-fitted panels and extraneous add-ons are not tolerated, as the exterior is subject to a particularly laser-like focus, and buyers want to be seen in the best.

“Yin and yang, black and white, balance is very important to a Chinese customer,” says Engler, who spent two decades designing in Europe before moving to China. “Balance and harmony, those are the key words here for design. You cannot skip it, you cannot work around it.”

Automakers have begun to step outside their traditional stomping grounds to introduce vehicles exclusively to China. These cars, designed and built in China, are the first tentative steps toward adapting to Chinese consumer preferences. VW’s Lavida, for example, is a fairly conservative remaking of the ubiquitous Golf. Chevrolet’s Sail is a classic brand resurrected for China.

In some ways, China is a more advanced market. Pollution regulations, which are in some ways stricter than the U.S. and Europe, translate to limited engine size and fantastic fuel efficiency, trends which some predict will envelop the Western markets in the years to come. Research into battery technology has a higher priority in China than in the United States, one result being an already-evident edge in some aspects of batteries.

The design trend isn’t all one-way. Chinese domestic manufacturers have long eyed lucrative Western markets for their products, and they face similar challenges in producing cars that appeal to Western consumers. The result has been some pretty weird ideas, a few of which were exhibited at the recent Detroit Auto Show.

But this may be the year we’ll find out just how well Chinese manufacturers have done: BYD, well established in China, plans to introduce an all-electric car to North America, and several other domestic Chinese companies have announced plans to enter the market soon.

Volvo is likely to end up in the hands of China’s Geely, and Hummer may be China-owned by the end of the month. Bits and pieces — a Ford engine, the Wheego Whip chassis — are just the beginning.

With the demands of the enormous Chinese market, the expansion of Chinese companies into the West and the introduction of Chinese vehicles to U.S., American consumers should expect to see some Chinese characteristics make their way across the ocean. “Decoration to enhance proportion,” says Engler, “may show up in North America in coming months.”

The increasingly early influence of Chinese design bureaus on globally designed cars means we might soon recognize that new cars are a little toned-down — balanced, as a Chinese designer might say. That doesn’t mean the Chevrolet Corvette or Ford F-150 will suddenly be remade. But some of the characteristics of Chinese cars and the influences of the people buying them will inevitably make their way to the United States.

That isn’t a bad thing. Because maybe the Mustang could use a little more harmony.

Global Worming



By ANDREW C. REVKIN

Global warming has become perhaps the most complicated issue facing world leaders. On the one hand, warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. On the other, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slowdown.

After years of preparation for climate talks taking place in Copenhagen through Dec. 18, 2009, President Obama and other leaders announced on Nov. 15 what had already become evident — that no formal treaty could be produced anytime soon. Instead, the leaders pledged to reach a placeholder accord that would call for reductions in emissions and increased aid to help developing nations adapt to a changing climate and get access to non-polluting energy options.

This would in theory give the nations more time to work out the all-important details. Negotiators would then seek a binding global agreement in 2010, complete with firm emission targets, enforcement mechanisms and specific dollar amounts to aid poorer nations.

At the heart of the debate is a momentous tussle between rich and poor countries over who steps up first and who pays most for changed energy menus.

Within the United States, Congress is similarly fighting over legislation on climate change. The House in the summer of 2009 passed a bill outlining a cap-and-trade system that could, over the next few decades, lead to an early end to conventional use of coal and oil, fuels that have underpinned prosperity and growth for more than a century. But between stiff opposition from energy interests and the overwhelming distractions of health care reform and the economy, the legislation has stalled in the Senate.

In international discussions over climate, Mr. Obama has urged other countries not to be discouraged by the stasis on Capitol Hill, pointing to big investments in energy efficiency, solar and wind power and his move to restrict greenhouse gases using environmental regulations.

In the meantime, recent fluctuations in temperature, seized on by opponents of emissions restrictions, have intensified the public debate over how urgently to respond. The long-term warming trend over the last century has been well-established, and scientists immersed in studying the climate are projecting substantial disruption in water supplies, agriculture, ecosystems and coastal communities. Passionate activists at both ends of the discourse are pushing ever harder for or against rapid action, while polls show the public locked durably in three camps — with roughly a fifth of American voters eager for action, a similar proportion aggressively rejecting projections of catastrophe and most people tuned out or confused.

Background

Scientists learned long ago that the earth's climate has powerfully shaped the history of the human species — biologically, culturally and geographically. But only in the last few decades has research revealed that humans can be a powerful influence on the climate as well.

A growing body of scientific evidence indicates that since 1950, the world's climate has been warming, primarily as a result of emissions from unfettered burning of fossil fuels and the razing of tropical forests. Such activity adds to the atmosphere's invisible blanket of carbon dioxide and other heat-trapping "greenhouse" gases. Recent research has shown that methane, which flows from landfills, livestock and oil and gas facilities, is a close second to carbon dioxide in impact on the atmosphere.

That conclusion has emerged through a broad body of analysis in fields as disparate as glaciology, the study of glacial formations, and palynology, the study of the distribution of pollen grains in lake mud. It is based on a host of assessments by the world's leadingorganizations of climate and earth scientists.

In the last several years, the scientific case that the rising human influence on climate could become disruptive has become particularly robust.

Some fluctuations in the Earth's temperature are inevitable regardless of human activity — because of decades-long ocean cycles, for example. But centuries of rising temperatures and seas lie ahead if the release of emissions from the burning of fossil fuels and deforestation continues unabated, according to theIntergovernmental Panel on Climate Change. The panel shared the2007 Nobel Peace Prize with former Vice President Al Gore for alerting the world to warming's risks.

Despite the scientific consensus on these basic conclusions, enormously important details remain murky. That reality has been seized upon by some groups and scientists disputing the overall consensus and opposing changes in energy policies.

For example, estimates of the amount of warming that would result from a doubling of greenhouse gas concentrations (compared to the level just before the Industrial Revolution got under way in the early 19th century) range from 3.6 degrees to 8 degrees Fahrenheit. The intergovernmental climate panel said it could not rule out even higher temperatures). While the low end could probably be tolerated, the high end would almost certainly result in calamitous, long-lasting disruptions of ecosystems and economies, a host of studies have concluded. A wide range of economists and earth scientists say that level of risk justifies an aggressive response.

Other questions have persisted despite a century-long accumulation of studies pointing to human-driven warming. The rate and extent at which sea levels will rise in this century as ice sheets erode remains highly uncertain, even as the long-term forecast ofcenturies of retreating shorelines remains intact. Scientists are struggling more than ever to disentangle how the heat building in the seas and atmosphere will affect the strength and number of tropical cyclones. The latest science suggests there will be more hurricanes and typhoons that reach the most dangerous categories of intensity, but fewer storms over all.

Steps Toward a Response

The debate over such climate questions pales next to the fight over what to do, or not do, in a world where fossil fuels still underpin both rich and emerging economies. With the completion of the United Nations Framework Convention on Climate Change at the Earth Summit in 1992, the world's nations pledged to avoid dangerously disrupting the climate through the buildup of greenhouse gases, but they never defined how much warming was too much.

Nonetheless, recognizing that the original climate treaty was proving ineffective, all of the world's industrialized countries except for the United States accepted binding restrictions on their greenhouse gas emissions under the Kyoto Protocol, which was negotiated in Japan in 1997. That accord took effect in 2005 and its gas restrictions expire in 2012. (The United States signed the treaty, but it was never submitted for ratification, in the face of overwhelming opposition in the Senate because the pact required no steps by China or other fast-growing developing countries.

It took until 2009 for the leaders of the world's largest economic powers to agree on a dangerous climate threshold: an increase of 2 degrees Celsius (3.6 degrees Fahrenheit) from the average global temperature recorded just before the Industrial Revolution kicked into gear. (This translates into an increase of 1.3 degrees Fahrenheit above the Earth's current average temperature, about 59 degrees).

The Group of 8 industrial powers also agreed this year to a goal of reducing global emissions 50 percent by 2050, with the richest countries leading the way by cutting their emissions 80 percent. But they did not set a baseline from which to measure that reduction, and so far firm interim targets — which many climate scientists say would be more meaningful — have not been defined.

At the same time, fast-growing emerging economic powerhouses, led by China and India, still oppose taking on mandatory obligations to curb their emissions. They say they will do what they can to rein in growth in emissions — as long as their economies do not suffer. The world's poorest countries, in the meantime, are seeking payments to help make them less vulnerable to the impacts of climate change, given that the buildup in climate-warming gases so far has come mainly from richer nations. Such aid has been promised since the 1992 treaty and a fund was set up under the Kyoto Protocol. But while tens of billions of dollars are said to be needed, only millions have flowed so far.

In many ways, the debate over global climate policy is a result of aglobal "climate divide.'' Emissions of carbon dioxide per person range from less than 2 tons per year in India, where 400 million people lack access to electricity, to more than 20 in the United States. The richest countries are also best able to use wealth and technology to insulate themselves from climate hazards, while the poorest, which have done the least to cause the problem, are the most exposed.

In Copenhagen in December 2009, negotiators had planned to try to settle on the basic terms of two new global climate agreements. One would renew the commitments of countries bound by the Kyoto emissions limits; the other would rein in emissions of all countries to varying extents, depending on their wealth and emissions history. Given the many competing interests, and the reality that any big emissions shifts would have substantial economic impacts, the negotiations have been called one of the most complex diplomatic challenges ever.

Democratic leaders in the United States Senate continue to try to follow the lead of the House of Representatives by securing passage of a bill aiming to sharply cut greenhouse gas emissions by 2050. The chief mechanism would be a "cap and trade" system that sets a gradually declining ceiling for over all emissions. Companies and institutions could buy and sell credits from one another as a way to curb emissions at the lowest cost. Companies that made deeper cuts than required could sell credits to companies that fell short of their targets.

But a national preoccupation with the slow economy and competing issues, led by health care, threaten to delay or weaken such legislation. Another impediment is the shortage of money flowing to basic energy research and large-scale demonstrations of non-polluting energy technology. While the Obama administration and Congress directed some stimulus money toward such efforts, such spending comes only after decades of declining investment in these areas.

President Obama came into office vowing to take swift action on climate change, and under him, the Environmental Protection Agency has declared that it will regulate carbon dioxide emissions. But with the cap-and-trade bill facing an uncertain future in the Senate, his ability to take big steps on the issue has been severely constrained, and without significant actions by the United States, China and India had made it clear they would remain on the sidelines. Just weeks before the planned Copenhagen session, he and other leaders gathered for an Asian summit announced that no treaty would be reached in 2009. Instead, leaders will try to reach a political agreement that could be the basis for new treaty talks in 2010.

In the meantime, a recent dip in emissions caused by the global economic slowdown is almost certain to be followed by a rise, scientists warn, and with population and appetites for energy projected to rise through mid-century, they say the entwined challenges of climate and energy will only intensify.

Green House Effect

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

Have you ever seen a greenhouse? Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.
The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.

The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.

A Passion for Personal Flight

Meet the Puffin. It's an airplane concept conjured up by the mind of aerospace engineer Mark Moore. The unusual looking, vertical take-off and landing tailsitter is only an idea, but you'd never know that from the attention the Puffin has gotten on the Internet.

Moore came up with the design for the electric powered, 12-foot (3.7 m) long, 14.5-foot (4.4 m) wingspan personal air vehicle as part of the coursework for his doctoral degree. Then Langley's creativity and innovation and revolutionary technical challenges funds paid for much of the research. How the Puffin rocketed from esoteric erudition to web sensation is a classic case study in the power of the viral nature of the web.

The animation of the Puffin on YouTube has gotten more 648,000 hits in a week," said Moore. "Until the concept was mentioned in the media Jan. 19, the video had only been clicked on a couple of thousand times since it was uploaded to the NASAPAV channel last November."

It all started with an email from a reporter who was pursuing a story on electric aircraft propulsion for "a couple of websites associated with space.com." As the former manager of the former Vehicle System program's Personal Air Vehicle sector. Moore is a nationally recognized expert on that and other small aircraft systems.

Moore not only shared information about electric motor research for airplanes, but also the Puffin design that he and a team from Massachusetts Institute of Technology, the Georgia Institute of Technology, the National Institute of Aerospace (NIA), and M-DOT Aerospace planned to present to an American Helicopter Society conference on aeromechanics, Jan. 20. Combine NASA cachet with an intriguing technology concept, some compelling animation created by Analytical Mechanics Associates graphic designers and quotable quotes from Moore and the story of the Puffin lifted off.

First it appeared on the Scientific American website from the original interview on electric aircraft propulsion. There Moore was quoted as saying the team named the design the Puffin because, "If you've ever seen a puffin on the ground, it looks very awkward, with wings too small to fly, and that's exactly what our vehicle looks like," Moore says. "But it's also apparently called the most environmentally friendly bird, because it hides its poop. So the vehicle is environmentally friendly because it essentially has no emissions. Also, puffins tend to live in solitude, only ever coming together on land to mate, and ours is a one-person vehicle."

The pictures and video of the Puffin helped attract media attention too. It's not everyday that you see a design that's part plane, part helicopter that stands upright on the ground. Its tail splits into four "legs" that serve as landing gear. It lifts off like a helicopter, hovers and then leans forward to fly horizontally with the pilot lying down like in a hang-glider.

Even the technical details were pretty interesting. If ever built the proposed aircraft would be small and very lightweight -- about 300 pounds (136 kg) empty weight plus another 100 pounds (45 kg) of battery and 200 pounds (91 kg) for the pilot or payload. The design would be powered by a total of 60 horsepower through electric motors, which are designed to be able to fail any two powertrain components on either side and still produce the required power to hover. It has a cruising speed of 150 mph (241 kph), but cruises more efficiently at lower speeds The range with current battery technology would be about 50 miles (80 km).

The first web story snowballed until the Puffin garnered worldwide attention, capturing more than 10 news.google.com search pages in less than seven days with stories in media from Japan, Russia, Germany, Hungary, Poland, Italy, Romania, Turkey, Chile, Spain, Guatemala, Greece, Peru, Mexico, Norway, Argentina, Czechoslovakia, China, Korea, and others. A full "Google" search of "NASA Puffin" indicated there were more than 38,000 hits for the combined words. Moore and the NASA Langley News Media Team got inquiries from a New York Times blogger, Germany's biggest Sunday paper, a French men's magazine, ABC News and many more. Even the social media site "Twitter" has been all a-twitter with more than 1,200 tweets about the Puffin in a week.

For Moore the publicity was an added bonus, but it was the way the work was accomplished that really excited him. "I've been doing conceptual design studies for 25 years, and this is the first time that I have performed a six month conceptual design study that involved such detailed analyses performed right from the onset (that is viscous full Navier Stokes Overflow aero solutions feeding WopWop aeroacoustic analysis, along with MBDyn rotor dynamics, with detailed transition trajectory analysis)," said Moore. "So I think it is a poster child of higher-order methods being able to push themselves far forward to the front stages of design -- to avoid the nasty 'real world' surprises that higher-order analysis can bring at later stages. Getting systems analysis to work in closer collaboration with discipline experts is greatly needed as we progress towards greater multi-disciplinary coupling to solve highly complex problems."

The other thing the engineer says he looks forward to is sharing the technical results of the studies and "the depth of analysis that exists" with other researchers. He'd much rather do that, Moore says, than talk to reporters.

As for the Puffin media frenzy -- it's subsided some, but could start back up later this year when the NIA hopes to fly a remote control one-third size model to validate assumptions made in academic studies, with the specific intent of exploring the transition from hover to forward flight.

Jurassic Space: Ancient Galaxies Come Together after Billions of Years


Hickson Compact Group 31 is one of 100 compact galaxy groups catalogued by Canadian astronomer Paul Hickson. Credit: NASA, ESA, S. Gallagher (University of Western Ontario), and J. English (University of Manitoba). Photo No. STScI-PRC10-08a



Imagine finding a living dinosaur in your backyard. Astronomers have found the astronomical equivalent of prehistoric life in our intergalactic back yard: a group of small, ancient galaxies that has waited 10 billion years to come together. These "late bloomers" are on their way to building a large elliptical galaxy.

Such encounters between dwarf galaxies are normally seen billions of light-years away and therefore occurred billions of years ago. But these galaxies, members of Hickson Compact Group 31, are relatively nearby, only 166 million light-years away.

New images of these galaxies by NASA's Hubble Space Telescope offer a window into what commonly happened in the universe's formative years when large galaxies were created from smaller building blocks. The Hubble observations have added important clues to the story of this interacting foursome, allowing astronomers to determine when the encounter began and to predict a future merger.

Astronomers know the system has been around for a while because the oldest stars in a few of its ancient globular clusters are about 10 billion years old. The encounter, though, has been going on for about a few hundred million years, the blink of an eye in cosmic history. Everywhere the astronomers looked in this compact group they found batches of infant star clusters and regions brimming with star birth. Hubble reveals that the brightest clusters, hefty groups each holding at least 100,000 stars, are less than 10 million years old.

The entire system is rich in hydrogen gas, the stuff of which stars are made. Astronomers used Hubble's Advanced Camera for Surveys to resolve the youngest and brightest of those clusters, which allowed them to calculate the clusters' ages, trace the star-formation history, and determine that the galaxies are undergoing the final stages of galaxy assembly.

The composite image of Hickson Compact Group 31 shows the four galaxies mixing it up. The bright, distorted object at middle, left, is actually two colliding dwarf galaxies. The bluish star clusters have formed in the streamers of debris pulled from the galaxies and at the site of their head-on collision. The cigar-shaped object above the galaxy duo is another member of the group. A bridge of star clusters connects the trio. A longer rope of bright star clusters points to the fourth member of the group, at lower right. The bright object in the center is a foreground star. The image was composed from observations made by the Hubble Space Telescope's Advanced Camera for Surveys, NASA's Spitzer Space Telescope, and the Galaxy Evolution Explorer (GALEX).

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center manages the telescope. The Space Telescope Science Institute conducts Hubble science operations. The institute is operated for NASA by the Association of Universities for Research in Astronomy, Inc. in Washington, D.C.

3D Sun for the iPhone

Imagine holding the entire sun in the palm of your hand. Now you can. A new iPhone app developed by NASA-supported programmers delivers a live global view of the sun directly to your cell phone. Users can fly around the star, zoom in on active regions, and monitor solar activity.

"This is more than cool," says Dick Fisher, director of NASA's Heliophysics Division in Washington DC. "It's transformative. For the first time ever, we can monitor the sun as a living, breathing 3-dimensional sphere."


The name of the app is "3D Sun" and it may be downloaded free of charge at Apple's app store. Just enter "3D Sun" in the Store's search box or visithttp://3dsun.org for a direct link.

Realtime images used to construct the 3-dimensional sphere are beamed to Earth by the Solar-Terrestrial Relations Observatory (STEREO), a pair of spacecraft with a combined view of 87% of the solar surface. STEREO-A is stationed over the western side of the sun, while STEREO-B is stationed over the east. Together, they rarely miss a thing.

Telescopes onboard the two spacecraft monitor the sun in the extreme ultraviolet (EUV) portion of the electromagnetic spectrum. "That's why the 3D sun looks false-color green," explains Lika Guhathakurta, STEREO program scientist at NASA Headquarters. "These are not white-light images."

That's okay because EUV is where the action is. Solar flares and new sunspots shine brightly at these wavelengths. EUV images also reveal "coronal holes," vast dark openings in the sun's atmosphere that spew streams of solar wind into the solar system. Solar wind streams that hit Earth can spark intense displays of Northern Lights.

"With this app, you can spin the sun, zoom in on sunspots, inspect coronal holes--and when a solar flare erupts, your phone plays a little jingle to alert you!" says Guhathakurta.

Indeed, many users say that's their favorite part -- the alerts. The app comes alive on its own when the sun grows active or when interesting events are afoot. For example, a recent alert notified users that a comet just discovered by STEREO-A was approaching the sun. When the comet was destroyed by solar heating, the app played a movie of Comet STEREO's last hours.

Readius - Floppy Tech!


Don't be confused........
its not 5 1/4″ disks!

Ever wanted a device that has a screen much bigger than the actual device?

Impossible? Not any more! The Readius from Polymer Vision is set to be just that impossible device!

The screen in the picture above folds out from the main body of the device. That’s right, a fully functional FOLDABLE computer screen!! The technology is Electronic Ink inside a foldable, rollable polymer screen. As with most E-Ink screens, it is only black and white at the moment, but even so,I think it’s another amazing step forwards.

Samsung CL65


Price:$4oo

The Samsung CL65 features a 12.2 megapixel 1/2.33" CCD image sensor behind a Schneider Kreuznach Varioplan-branded 5x optical zoom lens. The CL65's lens has actual focal lengths of 6.3 - 31.5mm, and 35mm-equivalent focal lengths of 35mm - 175mm - a rather tight wide angle through to a useful telephoto. Maximum aperture varies from F3.6 to F4.8 across the zoom range. The CL65's lens includes optical image stabilization, which should help reduce the likelihood of blur caused by camera shake, as part of what Samsung terms "Dual Image Stabilization". The other part of the function is Digital Image Stabilization, which combats blur using the camera's firmware, automatically raising the camera's ISO sensitivity (and noise levels) as needed.

There's no optical viewfinder, with images being framed on a 3.5-inch wide screen LCD display with 1,152,000 dots of resolution, which equates to around 384,000 pixels (likely an 800 x 480 pixel array). This unusually high-res display dominates most of the camera's rear surface, and also features a touch panel through which most control is achieved. The Samsung CL65 offers what Samsung calls a "Smart Gesture" user interface; when specific gestures are traced with a fingertip on the touch panel, the camera recognizes and responds appropriately. For example, tracing your finger in a cross mark on the screen will delete the current photo, while tracing a circle will instead rotate it. To switch between photos, you simply drag your finger to one side across the panel. In addition, the Samsung CL65 include an orientation sensor, and allows switching between photos by tilting the camera body to one side or other. The LCD touch panel is also used in record mode, with a tap of the finger on your subject being all that's needed to manually set the focus point. Holding your finger over the subject for two seconds will set focus and then trigger the shutter; alternatively you can press the shutter button immediately after focus lock is achieved. In addition, the CL65's display offers haptic feedback, which uses a slight vibration of the display surface as a method of tactile confirmation when the user presses an on-screen control. This vibration is accompanied by a beeping sound as a further form of confirmation.

Despite its slim 0.7-inch thick body, the Samsung CL65 is unusually feature-rich, including a built-in GPS receiver, as well as both wireless LAN and Bluetooth connectivity. The GPS receiver is used to automatically tag images as they're captured, recording into the EXIF headers the location at which the photo was shot (or when indoors away from GPS reception, the last location at which a fix was obtained). This location information can then be displayed on the CL65's LCD display in playback mode, as well as being used by some geotagging-aware software and websites such as Google's Picasa to arrange and allow searching of images based on their capture location. The wireless LAN connectivity meanwhile allows the CL65 to connect to 802.11b/g networks, so long as they don't require verification using a web browser before data can be transferred. Once connected, CL65 users can send reduced-resolution versions of photos and movies by email, or upload them to certain websites including Facebook, Picasa and YouTube. Images transferred by WiFi are automatically resized to a reduced resolution of two megapixels - good for speed of transfer, but it would perhaps have been preferable to let the user decide whether to upload a full-res version as desired. Email addresses for recipients can be stored in the camera's address book, and new addresses can be entered using an on-screen QWERTY keyboard. Finally, the Bluetooth 2.0 connectivity allows for transfer of images wirelessly to other Bluetooth devices such as cellphones. The CL65 will apparently automatically resize images to match the resolution of the remote device's screen, although we don't have precise details on how this is determined.

The Samsung CL65 includes face detection capability with both smile and blink detection functions, which can be used to automatically capture a photo when everyone's smiling, and then retake the image if anybody blinks. There's also a "Beauty Shot" mode which smooths skin tones on detected faces, and offers three user-selected levels of smoothing. The face detection is also used to offer a Red-Eye Fix function which automatically locates and corrects for this common image defect. In addition, the CL65 includes Smart Face Recognition technology, which allows twenty individuals' faces to be registered in-camera and then recognized in subsequent shots. Once identified, those individuals' faces will be given priority over unrecognized faces in the scene when determining exposure variables, and can also be searched for in the Smart Album playback mode. The Samsung CL65 also has a generous selection of scene modes aimed at keeping things approachable for beginner photographers while still offering a degree of control over images, plus a Smart Auto mode which automatically selects one of 16 scene modes as appropriate to the current scene.

The Samsung CL65 has the ability to record standard or high definition movies with sound at 30 frames per second in H.264 format, with a maximum resolution of 720p (1280 x 720 pixels). Connectivity options include HDMI video via an optionally available adapter allowing the camera to be connected to the latest high-definition displays. Alternatively, the CL65 includes standard definition NTSC / PAL video output. Power comes courtesy of a proprietary SLB-11A Lithium Ion rechargeable battery. The Samsung CL65 stores images on the tiny MicroSD / MicroSDHC card format, or in 100MB of built-in memory.

The Samsung CL65 ships from September 2009, with pricing set at about $400.

LG EnV Touch (Verizon Wireless)





The LG EnV Touch was a surprise to us. We thought all of the EnV line of phones would be in the style of the LG EnV VX9900, the LG EnV2, and the more recent LG EnV3.Those phones had numeric keypads on the front, with QWERTY keyboards behind their flip designs. But it appears that the LG EnV Touch is actually a successor to the Voyager VX10000, due to its full touch screen-interface. Perhaps Verizon and LG are going back to the EnV name to reinforce its association with high-end messaging phones.

We gave the LG Voyager VX10000 an Editors' Choice award when it first launched, but it has been almost two years since then, so it's about time for an upgrade. The LG enV Touch definitely offers better design and features. Both the touch-screen and internal displays are bigger, the keyboard has a better layout, the 3.2-megapixel camera has more advanced settings, the 3.5mm headset jack accommodates your own headphones, EV-DO Rev. A offers faster Web browsing, and more. The EnV Touch doesn't have V Cast Mobile TV like the Voyager did, but that's about the only thing missing with this upgrade. Perhaps our only complaints were that the touch-screen interface and Web browsing could use some refinements, and the lack of Wi-Fi was disappointing.

The LG EnV Touch is available for $149.99 with a $70 mail-in rebate and a two-year service agreement, which isn't too expensive for what you're getting.

Design
When the LG Voyager came out two years ago, touch-screen phones were still relatively new. The market is now flooded with them, and the EnV Touch doesn't seem so unique now. However, that doesn't take away from the EnV Touch's design appeal. Measuring 4.52 inches long by 2.16 inches wide by 0.66 inch thick, the EnV Touch is slimmer than the Voyager, though at 4.92 ounces, it's a bit heavier. It has a sleek and stylish look similar to that of the LG Dare and the LG Versa, with a solid feel in the hand and a sturdy hinge construction.


Like the Voyager, the EnV Touch has a large touch-screen display dominating its entire front surface, except for three physical keys at the bottom; the Send, Clear, and End/Power keys. The Clear key doubles as the voice command key (with a short press) and the voice recorder key (with a long press). The touch screen is really stunning, measuring 3 inches diagonally, which is a hair larger than the 2.81-inch display on the Voyager. The display supports a whopping 1.6 million colors and is bright, sharp, and vibrant. You can adjust the screen's backlight time, the charging screen, (what shows on the display when the phone is charging), the menu fonts, and the dial fonts.

Along the bottom of the home screen are five shortcut icons that lead to the messaging menu, the virtual dial pad, the main menu, the phone book, and a Favorites page, where you can list your favorite contacts or group. You'll also find a small arrow to the far right of the display. Tap that, and you'll reveal a pull-out menu of application shortcuts and shortcuts to media files in the My Media library (Media files include photos, browser bookmarks, and videos). You can then drag and drop those shortcut icons directly to the home screen, which is similar to what you can do on the LG Dare. Some of the application shortcuts will just appear as simple icons, like the browser for example. For certain applications, like the calendar and the clock, they will appear as full-on widgets on the home screen. If you want to add a shortcut that's not listed on the pull-out menu, you can tap the Add button on the bottom right to select from your entire library of applications and media files. If you wish to remove the shortcut from your home screen, simple drag and drop the icon to the small arrow on the right.

On the whole, we found the touch-screen interface to be quite responsive. There's a touch calibration wizard that you can go through to help with your precision and sensitivity, and the haptic feedback makes the phone vibrate whenever your touch registers. You can even adjust the length and intensity of the vibration. Also helpful is a sound effect whenever your touch registers on the screen. Aside from just tapping, you can also scroll through menus and long Web pages by dragging your finger across the screen.

Despite all this, the touch-screen interface takes some acclimation. This is especially true with the Web browser, where you need to tap a particular icon just right for it to register. We had to tap links several times before it got through, for example. Also, when scrolling through menus, we would sometimes launch an application accidentally. We got used to it after awhile, but it was frustrating at first.

Instead of having to open up the phone to dial or text, you can do both via the touch-screen interface. We liked the virtual dial pad's large digits. Underneath the keypad are shortcuts to voice dialing, the recent calls list, and the contacts list. As for messaging, you can choose a few ways to enter text: handwriting recognition, multitap or T9 via an alphanumeric keypad, or via a landscape QWERTY keyboard.

The EnV Touch has an internal accelerometer, so you can activate the QWERTY keyboard by rotating the phone horizontally. When using the QWERTY keyboard, each key magnifies as you touch it to show that you selected it, much like the keyboard on the iPhone. All of these text entry methods work fine as far as touch-screen interfaces go, but we would definitely choose to use the actual physical keyboard over the touch screen for faster typing.

On the left spine of the EnV Touch are the dedicated camera key, the volume rocker, and the screen lock key. The charger jack is on the bottom, while the microSD card slot and 3.5 millimeter headset jack are on the right side. We're especially glad to see the 3.5 millimeter headset jack, as it's always good to have the option of using your existing headphones. On the back are the 3.2-megapixel camera lens and an LED flash.

The 3-inch internal display is just as large as the external display and just as attractive, with the same color support and pixel resolution. You can adjust the backlight time separately from the external display. You can also change the menu style interface. Do note that you need to open the phone all the way to 180 degrees to access the controls on the left spine.
