Duh...... Common sense dude.... Anyone who had a brain would realise one should consider all the options in business, and many of those projects have been well described/publicised eg Arnies recent HSR tour around the compeititors.

LOL, so just as I thought. You had no clue those mentioned in the report wanted at German and Japanese but chose China just because of 'budget'. Saying so was just wishful thinking on your part, no surprises there. :D

Its not that the other countries products are unrealistic, higher production costs, and very possibly better quality, adds to the cost

Having trains traveling along atspeeds up to 800KPH is not that far fetched for the future. China, Europe North Amarica are ideal continents for very long distance high speed rail of some sort. and are you suggesting Siemens sucked the Chinese in with the Maglev then?. Too get to speeds of 600-800kph to match airliner cruising speeds "Maglev" might be the only way. As Martin said earlier overheating of the wheels at extreme speeds is a problem.

Considering products from China were not known for their quality or reliability in the past,etc etc, while German stuff which in this case Siemens is, it then becomes a bit of a calculated gamble ............Chinas 6yrs experience which needed foreign help, .compared to decades for the others............... :coffee:

So you're agreeing China's HSR offers the best business proposition ?? You could have just said so instead of all these mumbo jumbo. :D

On second thoughts you are quite right, I should have paid more attention to zoom's post Being third world countries where business deals can be less than transparent, who knows what went on. Argentina and South Africa arent exactly rolling in the money, so as the saying goes " You cant have champange on a beer budget.

Futhermore, according to a article in the previous publication of the Economist, Siemens CEO has been implicating a policy of "No more contracts at all costs", thereby no more shonky deals:D:D

You were the one that had the issue with my statement that China's progresss in HSR owed a lot to Western Tech Transfar:nono:

So losing out on the deals means they were 'less than transparent' and 'shonky deals' were involved ? The tooth fairy told you this ?
If only they pay as much for sour grapes as they do for HSR tech, you would be laughing your way to the banks instead of whining here. :rofl:

Paper-Thin Screens With a Twist

"Paper-Thin Screens With a Twist
Gold Winner | Industrial Technology Research Institute
SEPTEMBER 26, 2010
By MICHAEL TOTTY

Lots of researchers have been trying to come up with a way to make flexible displays that work like computer screens but with a literal twist—they can be bent, rolled and folded like a sheet of paper.

The Taiwan-based Industrial Technology Research Institute, or ITRI, won the top prize in this year's Innovation Awards contest for a manufacturing technique that promises to clear the way for commercial development of high-quality displays on flexible materials.

Flexible displays are attractive for several reasons: They're lighter than glass displays, making it possible to build larger consumer devices, such as e-readers or tablet computers, that aren't too heavy. They can also be used in some novel applications, such as interactive newspapers that can be bent or rolled and be as portable as the paper-based versions.

"With a stable, viable and cost-effective flexible-display technology," says Barry H. Jaruzelski, an Innovation Awards judge and a partner at consulting firm Booz & Co., "the door is opened to a wide range of truly new applications in consumer electronics and device interfaces."

But producing flexible displays in commercial quantities has proved challenging. To understand why, and why ITRI's innovation has promise, requires a brief tutorial.

Making a flexible display as fully functional as the typical flat-panel computer screen requires layering thin-film transistors on a flexible substrate. Because the flexible material can curl or shift during this process, it's bonded temporarily to a rigid piece of glass. The completed flexible display then has to be detached from the glass without being damaged, which is difficult to do efficiently enough to make the displays on a commercial scale.

ITRI's solution—which it calls FlexUPD, for flexible universal panel for displays—is novel yet simple. It places a "debonding" layer of nonadhesive material between the flexible substrate and the glass. The substrate, which has an adhesive backing, is made slightly larger than the final flexible display and the debonding layer, so it stays steady on the glass. Once the transistors are layered on the substrate and enclosed, the display can be cut out from the excess substrate and easily lifted off the glass.

The idea for the debonding layer, says an ITRI spokeswoman, came from watching cooks prepare paper-thin Taiwanese pancakes, which can be easily peeled from a pan at high temperatures. Cheng-Chung Lee and Tzong-Ming Lee, ITRI division directors, are credited with the idea.

The technique, the institute says, can be used with a variety of displays, including current liquid-crystal-display, or LCD, screens and the next-generation displays made with organic light-emitting diodes, or OLEDs.

ITRI has demonstrated a prototype paper-thin display made with this process, and has licensed the technology to display maker AU Optronics Corp. of Taiwan. The first product using the technology, a flexible display for an e-reader, is planned for release by the end of the year, an ITRI spokeswoman says.

Other companies have demonstrated flexible-screen prototypes and plan to bring them to market using a different manufacturing technology. None, including ITRI's technology, have yet seen commercial success, but ITRI says its improvements make its entry more cost-effective than competing technologies. Also, it says, the technology is compatible with existing factories for fabricating displays, so it can be widely adopted by display makers.

Judges for the Innovation Awards, while noting that ITRI is still in the early stages of commercializing the technology, cited the possible benefits of flexible displays. "This looks like a simple and elegant solution to a manufacturing problem," says William Webb, director of technology resources for Ofcom in the U.K.

ITRI, a nonprofit organization, won an Innovation Award in 2009 for its FleXpeaker, a paper-thin loudspeaker system.

CHENGDU - The first subway in west China was launched on Monday afternoon in Chengdu, capital of Southwest China's Sichuan province.

Chengdu Subway Line One runs between northern and southern Chengdu over a distance of 18.5 km with 17 stations, said Yu Bo, chief engineer of Chengdu Metro Co, Ltd, builder and operator of the line.

The subway's construction began in 2005 with an investment of about 8 billion yuan ($1.19 billion).

The subway operates from 7 am to 9 pm with an interval of 10 minutes between trains. It is designed to carry 180,000 to 200,000 passengers per day.

Chengdu will accelerate its subway construction in the next few years. It plans to have a 298 km subway system, carrying more than three million passengers per day by 2020, Yu said.

It appears some people can't face the truth even when its staring them in the face. The fact that you can only resort to making "non related remarks" suggests that you dont have anything to offer in refuting my observation made in previous posts." Chinas HSR was done with foreign help which speeded up their expertise......etc

Fact. Technology transfers are an integral part of western companies being allowed to supply to China’s own massive rail development projects. If it hadnt taken place,China's progress in HSR would not have been as quick as it was. More than likely, under the technology transfer agreements, technology may not be then used in export contracts but it is entirely possible that a modification to a design or technique can circumvent such restrictions or that greater understanding of the technologies involved could allow Chinese designers to engineer alternative solutions that do not blatantly infringe upon any agreements.
This has enabled China to come from nowhere to become a serious challenger io Japan and the West in 6yrs in a field which they probably felt they would command for many yrs.

Sour grapes it may be, but in future the West or Japan should think twice before agreeing to transfer advanced technology China, just for the contract. Those things come back and bite you on the bum, as evidenced. THese are more jobs that the West and Japan has lost for its people.. ::nono:

It's swings and roundabouts.I don't believe any one country, or company for that matter,can claim 100% to have pioneered anything.We all learn from the world we live in,can't you just accept that instead of trying to claim one-upmanship for this that or another.It is very childlish and rather tedious to read these continuous comments on this forum.

Here is a guy credited to bringing Boeing's first financial success story( yes that's right i did say Boeing).Who should get the credit,China for producing and educating ,England for their part in his Vocational studies or USA for developing his skills ,or what about Taiwan?

Wong Tsu (1893 – 1965) was born in Beijing, China. At the age of 12, he was selected as a naval cadet, and at 16 he was sent to England to study naval engineering, then to the U.S. to study aeronautical engineering at the Massachusetts Institute of Technology.

Graduating in 1916, he learned to fly at the Curtiss Flying Boat School in Buffalo, New York. He was then hired by the fledgling Boeing aircraft company and designed its first product, the Boeing Model C (

), more than 50 of which were acquired by the U.S. Navy. In 1917, after two years at Boeing, he returned to China where he became chief secretary of the airline China National Aviation Corporation. When the Kuomintang government was defeated in the civil war, Wong went to Taiwan where he became professor of aviation at Cheng Kung University.

During his lifetime, Wong is believed to have had a hand in designing 30 aircraft. In 2004, at a time when it was hoping to increase its ties to the Chinese aviation industry, Boeing unveiled a plaque and exhibit at its Museum of Flight in Seattle, Washington, honoring his work as its first engineer.

In the U.S. his name is sometimes inverted to Tsu Wong, to put the family name last.

aah, so it was China who transferred technology to Boeing...i see and they claimed it an "all Boeing " design too.

Try telling that to Martin. One upsmanship seems to be the preserve of the more nationalistic orientated members, mean while claims for having the biggest can be quite embarassing. Members over at WAB were having a good old laugh at a Chinese newspaper claim that their 10000ton hospital ship was the biggest in the world.

No I disagree, China didnt provide anything other than a very capable person( Your source doesnt indicate that he was inclined towards designing aircraft at the time of leaving China), and as you said learn't and applied his skills outside his homeland. Meanwhile its not unusual, while working for a company, any product that a employee develops for that company, remains the property of that company, therefore Boeing has every right to claim it as theirs.

While your your example of how developments are the sum of many parts is true, surely there would have to be a dividing line, otherwise we will be tracking everything back to Adam and Eve

We live in a different world now, therefore any steps should be strongly considered, to maintain an advantage.
So in this instance had Siemens or any Japanese company, decided that the opportunity in China wasnt worth the tech transfer, whose ruling the HSR market could be different.
I stand to be corrected on this but when China called for a co development of an engine for their budding passenger aircraft market none of the big three have responded?

I'm not correcting you but i would like to point you to this excellent article that reveals the agony of the Company CEO's who have to confront this problem and how they think it through.

Researchers Make Paper-thin Stereo Speakers for LCD TVs, More

"Researchers Make Paper Stereo Speakers for LCD TVs, More
Dan Nystedt, IDG News
Apr 27, 2009 12:20 am

A Taiwanese research group has developed stereo speakers in paper, which will lead to low-cost speakers perfect for thin devices such as LCD TVs or even talking movie posters to be used as advertisements.

Engineers at Taiwan's Industrial Technology Research Institute (ITRI) have already produced rolls of paper stereo speakers and say they will be used in cars starting from next year. They are also planning a splash introduction of the new technology at a big exhibition in Taipei next year in which they will unroll a three-story high banner that can blare out tunes.

"A lot of companies are interested in this product," said Chen Ming-daw, a research director at ITRI. "We don't have enough people to handle all the attention right now."

They call it Flexpeaker because you can roll it up or fold it just like regular paper.

One cool way the technology will be used is on movie posters.

The goal for the researchers is to be able to mass produce standard poster-size speakers (A2, or 60centimeters by 44cm) costing just US$20 each. Movie makers could then put out posters with soundtrack music or movie highlights emanating from them as people walk by.

The special paper is made by sandwiching thin electrodes that receive audio signals and a prepolarized diaphragm into the paper structure. A special Flexpeaker adapter between the MP3 player and the speaker is used to play music through the paper. But in a year, ITRI hope to develop a chip that will do away with the adapter and allow people to plug a digital music player directly into the speaker.

They're also working on wireless technologies.

In July, the group will show off its first Bluetooth enabled paper speaker, which will eliminate the need for wires, said Liou Chang-ho, project manager of ITRI's Flexpeaker initiative.

One limitation with Flexpeaker is that while it's very good with sounds at frequencies between 500Hz to 20KHz, it doesn't handle low frequency sounds well.

That problem can be offset by adding a subwoofer to any system with the paper speakers, said Liou. That's the idea ITRI is working on for LCD TV makers. The paper speakers are so thin that they're perfect for the current push to ultra thin LCD TVs, a maker simply has to add a subwoofer to make a quality sound system.

ITRI is already working with a company to produce the speakers in rolls, like rolls of paper.

"Once it's being made in rolls, the cost will drop a lot," said Liou."
