U.S. researchers closer to creating new solar cells

LOS ANGELES, Nov. 29 (Xinhua) -- U.S. researchers have taken one step closer to creating high-efficiency solar cells using cheap plastic with a dash of silicon, it was announced on Saturday.

    The solar cells, being developed by researchers at the University of California in Los Angeles (UCLA), have significantly greater sunlight absorption and conversation than previous polymers, the university said in a press release on its website.

    The researchers want these easy-to-use plastic solar energy cells to be sold at local hardware stores, and then hung like posters on the wall, said the release.

    "We hope that solar cells will one day be as thin as paper and be attached to the surface of your choice," said co-author Hsiang-Yu Chen, a UCLA graduate student in engineering. "We'll also be able to create different colors to match different applications."

    The research team found that substituting a silicon atom for carbon atom in the backbone of the plastic markedly improved the material's photovoltaic properties, said the release.

    The new polymer solar cells use organic compounds to produce electricity from sunlight, are much easier to produce than traditional silicon-based solar cells and are also environmentally friendly, the release said.

    "Previously, the synthesizing process for the polymer was very complicated. We've been able to simplify the process and make it much easier to mass produce," said Jianhui Hou, UCLA postdoctoral researcher and co-author of the study.

    "Though this is a milestone achievement, we will continue to work on improving the materials," he said.

    "Ideally, we'd like to push the performance of the solar cell to higher than 10 percent efficiency. We know the potential is there," he added.

China to launch new remote sensing satellite

JIUQUAN, Gansu Province, Nov. 30 (Xinhua) -- China will launch a new remote sensing satellite "Yaogan " on Monday at the northwestern Jiuquan Satellite Launch Center in the northwestern province of Gansu, an official with the center said on Sunday.

    The satellite was to be aboard a Long March-2D carrier rocket into the space "at an appropriate time", the official said.

    At present, both the rocket and the satellite were in good condition and the preparation went on well.

    The satellite would be used for scientific research, land resources surveying, crop yield estimate and disaster prevention and relief. "It will play a positive role in the country's economic development," he said.

    Its predecessor "Yaogan III" was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province on Nov. 12, 2007.

    The "Yaogan I" satellite was launched from Taiyuan on April 27,2006, and the "Yaogan II" was launched on May 25, 2007 from Jiuquan.

Vodafone Eying €2.8 Billion Take-Over of German Cable TV Operator

Vodafone is reported to be in talks which could lead to a €2.8 billion take-over of the German cable TV operator, Kabel Deutschland (KDG). The company is currently owned by the private equity group, Providence - which brought the company three years ago.

KDG has around 11 million customers in Germany and would be a good fit with Vodafone's local landline subsidiary, Arcor which controls about 14% of the broadband market.

KDG announced increased second quarter revenues last week, by 15.4% to €339.3 million while EBITDA increased 30% to €142.9 million. The higher numbers are partly attributable to the networks acquired earlier this year from the Orion Cable Group.

The firm recently confirmed that it was taking another look at trying to acquire some smaller regional operators. In 2004 KDG tried to buy two cable operators serving regional areas, which would have given the company nationwide coverage, but the deal was blocked by the cartel office amid fears of the company gaining a dominant market position. Changes in the market place with the emergence of telcos providing TV services should make cartel fears easier to overcome.

“A nationwide cable operator would enhance competition vis-à-vis the large telephone incumbents which would also be in the best consumer interest. We want to play a leading role in any such market consolidation,” KDG's CEO, Adrian v. Hammerstein said when the company announced its financial results last week.

Kabel Deutschland was founded in January 1999 by Deutsche Telekom, after it was ordered to spin off its entire cable TV business as required by regulatory terms.

For historic reasons, Kabel Deutschland cannot offer its products directly to all are connected via Kabel Deutschland's network, since only one third of all viewers are direct customers. In the early 1980s, when the cable network was originally established, Kabel Deutschland's predecessor Deutsche Bundespost had to leave in-house cables to other companies or the house owners. This turned out to be a significant obstacle since Kabel Deutschland now has to make single contracts with hundreds of small cable operators.

Bangladeshi Confirms 3G Licenses by Next March

Bangladesh's telecoms regulator, the BTRC has confirmed that it plans to award 3G licenses in the country by March 2009 - a delay on earlier promises to offer the licenses by the end of this year. During the launch of a trial 3G network by Ericsson in August, BTRC chairman Maj Gen (retd.) Manzurul Alam put a valuation of US$200 million on the licenses.

"The 3G licences will be issued by March next year ... the licences would be awarded through an open auction," Alam told the Reuters news agency.

A couple of months ago, the regulator sold a tranch of additional radio spectrum for US$204 million. Three incumbent operators brought the spectrum which the regulator said was necessary to cope with their increasing subscriber base.

Grameenphone, Banglalink and Aktel bought 7.5, 5 and 5 megahertz frequency respectively, at the rate of Tk 80 crore per MHz - giving them 21.9MHz, 17.5MHz and 17.8MHz respectively. Three other operators did not bid for the spectrum. Teletalk has 15.2MHz, Warid has 15MHz and Citycell has 10MHz.

A report by the GSMA last year had called on the regulator to issue the licenses by the 3rd quarter of this year. The spectrum should be licensed in a way that reflects its economic value and ensures it is efficiently used, the GSMA report argued.

The launch of 3G services could also assist in closing the "digital divide" which results in Bangladesh being poorly served by broadband internet services. A recent ITU report on telecoms in the Asia-Pacific region found that the minimum advertised broadband speed in countries such as Hong Kong and Japan is faster than the maximum broadband speed available in Bangladesh.

The country currently has six operators - and according to figures from the Mobile World, ended the first half of this year with just under 43.7 million mobile subscribers - which is still a population penetration level of 28.5%. Also worth noting is that while the country has six operators, only four of them are of any significant scale, Grameenphone (20.3m), Banglalink (9.5m) and Aktel (7.8m) and finally, Warid Telecom (3.3m). The two remaining long term incumbents, Citycell and Teletalk add up to 2.7 million customers between them.

O2 UK Launches Low-Energy Phone Charger

UK mobile operator, Telefónica O2 has announced the launch of an energy efficient universal mobile phone charger, which the company says is amongst the most energy efficient in the UK cutting energy consumption by as much as 70 per cent compared to standard mobile phone chargers.

The O2 Universal Charger, which meets the strict energy efficient guidelines of the US Energy Star rating, contains a power control system. This system considerably reduces charge to the mobile phone once the battery is fully charged even if the charger is left switched on in a plug socket. O2 estimates that phones left on charge costs Brits over £30 million in wasted energy every year. Heat loss from the charger has also been eliminated, another source of significant energy loss from standard mobile chargers.

Recent research conducted by O2 has revealed that a typical mobile phone charger wastes over 2.8 KWh of energy per year. O2 estimates that by cutting off the unneeded charge to mobile phones, the Universal Charger could save the equivalent carbon emissions of over 36,000 cars per annum. In addition to being energy efficient, the base unit of the Universal Charger will be accompanied by an inter-changeable leads making the charger compatible with most leading brands of mobile phones and eliminating the need to use a different charger with each mobile.

Ronan Dunne, CEO, Telefónica O2 UK, comments: “People are becoming increasingly concerned about the impact products are having on the environment and with mobile the single biggest impact is the energy used in charging. The O2 Universal Charger offers customers a simple yet effective way of reducing the environmental impact of their phones and reduces the waste associated with charger disposal.”

Iraq to Fine All Three Mobile Networks Over License Breaches

Iraq's three mobile phone networks all face fines from the government for apparently failing to meet conditions in their network licenses - reports Middle East Economic Digest (MEED). All three networks have failed to meet QoS requirements, while Korek Telecom has been censured for failing to meet coverage requirements.

The smallest operator, Korek Telecom has a national license, but coverage which is limited to mainly the Northern region of the country. An expansion to national coverage would need the financial muscle of an outside partner - which has lead to recent rumours that Etisalat is in talks to take a stake in the firm.

"Asiacell is bad and Zain is very bad," Hayam al-Yasiri, an adviser to the Telecommunications Ministry told MEED. "Korek is breaching the licence because of the coverage and the service. Korek up to this moment does not cover many cities, although according to the licence they should cover them."

The decision on the fines is expected before the end of the year

Romania Grants WiMAX License

Romania's new telecoms regulator, ANC (which recently replaced ANRCTI) says that it has awarded a WiMAX 3.6Mhz license to Radiocommunications National Society (SNR) for a payment of €2 million.

SNR was granted the right to use the 3657-3685 MHz and 3757-3785 MHz frequency bands under the terms of the Government Emergency Ordinance no.18/2008. By observing the provisions of this Ordinance, SNR released the 3600–3657 MHz and 3700–3757 MHz radio frequency bands it held, thus receiving the right to implement BWA systems in the two remaining sub-bands. As regards the released bands, ANC is currently conducting a comparative selection procedure in view of granting two licences.

The minimum license conditions require the coverage of at least 50 cities and at least 20 towns. The coverage is defined in relation to the number of base stations installed and in operation in a certain locality, within a certain deadline.

The amount of the licence fee to be paid by SNR was calculated proportionally to the validity period of the right to use the radio spectrum. SNR is entitled to use these radio frequencies until 24 July, 2011.

"Dawning 6000" to use Chinese-made Loongson processor

The high-performance computer "Dawning 6000," which will have a computing speed over 1,000 trillion operations per second, will adopt the Chinese-made general processor Loongson for the first time as its core component. This is according to the Dawning Information Industry Company.

"Dawning 6000" is currently jointly developed by the Institute of Computing Technology under the Chinese Academy of Sciences and the Dawning Information Industry Company.

Li Guojie, chairman of Dawning Information Industry Company and director and academician of the Institute of Computing Technology, said research and development of the Dawning 6000 is expected to be completed in two years. By then, Chinese-made high-performance computers will achieve two major breakthroughs: first, adopting domestic-made central processing units (CPUs) will be technically obstacle-free; second, the existing cluster-based system structure of high-performance computers will be changed once the computing speed reaches 1,000 trillion operations per second.

In Courtroom Showdown, Bush Demands Amnesty for Spying Telecoms

Fort_gordon

SAN FRANCISCO — The Bush administration on Tuesday will try to convince a federal judge to let stand a law granting retroactive legal immunity to the nation's telecoms, which are accused of transmitting Americans' private communications to the National Security Agency without warrants.

At issue in the high-stakes showdown — set to begin at 10:00 a.m. PST — are the nearly four dozen lawsuits filed by civil liberties groups and class action attorneys against AT&T, Verizon, MCI, Sprint and other carriers who allegedly cooperated with the Bush administration's domestic surveillance program in the years following the Sept. 11 terror attacks. The lawsuits claim the cooperation violated federal wiretapping laws and the Constitution.

In July, as part of a wider domestic spying bill, Congress voted to kill the lawsuits and grant retroactive amnesty to any phone companies that helped with the surveillance; President-elect Barack Obama was among those who voted for the law in the Senate. On Tuesday, lawyers with the Electronic Frontier Foundation are set to urge the federal judge overseeing those lawsuits to reject immunity as unconstitutional. At stake, they say, is the very principle of the rule of law in America.

"I think it does set a very frightening precedent that it's okay for people to break the law because they can just have Congress bail them out later," says EFF legal director Cindy Cohn. "It's very troubling."

The judge presiding over the case, U.S. District Judge Vaughn Walker of San Francisco, announced late Monday he wanted to discuss 11 questions (.pdf) at Tuesday's hearing, one of which goes directly to the heart of the immunity legislation.

"Is there any precedent for this type of enactment that is analogous in all of these respects: retroactivity; immunity for constitutional violations; and delegation of broad discretion to the executive branch to determine whether to invoke the provision?," the judge asked.

Carl Tobias, a professor at the University of Richmond School of Law, says the immunity legislation, if upheld, "makes it possible to extend immunity to other areas of the law."

He agreed, for example, that it would not be far-fetched to imagine Congress immunizing ExxonMobil for the 1989 Valdez oil spill "for national security reasons." A jury awarded about $5 billion in punitive damages in that case, an amount the courts reduced to $500 million.

In the telecom immunity challenge, the government argues that the telecoms should not be punished, or suffer the threat of punishment, for a surveillance program that the Bush administration claims was designed only to fight terrorism. The government also denies the lawsuits' allegations that the surveillance was a broad dragnet that sucked down Americans' communications on a wholesale basis.

The administration also says the immunity is warranted because the lawsuits threaten to expose government secrets.

The EFF brought the original spying lawsuit in 2006 against AT&T, and has since been joined by dozens of others targeting the nation's telecommunications companies.

The EFF's case, which has been consolidated with the others in the U.S. District Court of San Francisco, includes so-called whistle-blower documents from a former AT&T technician. The EFF claims the documents describe a secret room in an AT&T building in San Francisco that is wired to share raw internet traffic with the NSA.

The government sought to dismiss the original EFF case, and others that followed, on the grounds that they threatened to expose state secrets. Judge Walker has ruled against the government, saying the case could proceed.

The government appealed. But before the appeal was decided, Congress on July 9 gave the president the power to grant immunity to the carriers.

The EFF is now challenging the immunity legislation on the grounds that it seeks to circumvent the Constitution's separation of powers clause, as well as Americans' Fourth Amendment rights against unreasonable searches and seizures.

"The legislation is an attempt to give the president the authority to terminate claims that the president has violated the people's Fourth Amendment rights," the EFF's Cohn says. "You can't do that."

Two weeks ago, the administration told Walker in a court filing (.pdf) that the immunity legislation "represents the considered judgment of our nation's political branches that, in the unique historical circumstances following the 9/11 attacks, telecommunications companies should not bear the burden of defending against claims that those companies assisted the government in its efforts to detect and prevent further terrorist attacks."

Congress, the government continued, "concluded that those companies should not face further litigation if they provided such assistance pursuant to a court order or a written certification, directive or request from a senior government official, or did not provide the alleged assistance."

The immunity law allows the government to file a classified brief with Judge Walker activating immunity for a particular communication company. Walker then has little power to deny the request, unless the judge finds the immunity legislation is itself unconstitutional.

Oral arguments in Walker's courtroom are scheduled for 10 a.m. PST on Tuesday. Threat Level will cover the proceedings live.

More Rumours of a Nokia Laptop Computer

Rumours that Nokia may start production of its own brand laptop computers have resurfaced after UBS analyst Maynard Um issued a research note saying that it was increasingly likely to happen

Ericsson Portable PC (credit Datasalen)

"Given the rise of net-books/dongles sales, convergence between high-end mobile phones and laptops, and forays by computer manufacturers (Apple, HP) into smartphones, we think it is only a matter of time before Nokia launches notebook type devices,” Um wrote in the note - warning that they he does not expect a product to hit the shops until Q3 2009 at the earliest.

"Our checks indicate Nokia may be working on a 9”-10” notebook/tablet PC with a second OLED display, touchpad, near field communication (NFC) capability, HDMI out, and Linux OS. Given its seemingly higher end functionality, we do not think it will compete in the traditional netbook (~US$400) market."

There were rumours around April this year that Nokia was looking at launching a range of computers - but this was firmly refuted at the time by Nokia’s global marketing VP, Anssi Vanjoki.

Vanjoki said: "I have heard the rumours and I can categorically say Nokia is not entering the laptop market." Although Apple is known for selling laptop computers, Vanjoki said: "They sell some Notebooks, but the growth is from iPods. I don’t think they’re having commercial success with Notebooks."

It is worth noting though that Nokia sold computers in the past.

In the mid 1980's Nokia had a PC division, and merged it with Ericsson Information Systems, whose origins lay in the purchase by Ericsson of the computer business of Saab. The merged company, Nokia Data was later sold to UK based ICL in 1991 - and later became part of the larger Fujitsu group.

Nokia Data's most notable computer was the MikroMikko 1 - which was sold around the world.

Ericsson for its part sold mainly IBM compatible computers - and even launched a laptop (by the standards of the time) in 1985.

Amazon's database service enters public testing

SimpleDB, one of Amazon.com's suite of online services that people can use to build Web sites or other computing operations, is out of private beta testing.

The service lets programmers store database records at Amazon and extract specific data from them. Along with the shift to public beta testing, Amazon cut the price for storing data from $1.50 to 25 cents per gigabyte per month.

SimpleDB, introduced nearly a year ago, is a newer arrival into the Amazon Web Services suite. Other services let customers process data, store raw data, distribute content, and store messages sent among different computers.

The company also announced basic level of use is free for at least six months--the first time the company has done so with one of its Web services. After various thresholds are met in data transfer and computer processing, customers must pay according to usage.

"We've made the business decision to go with SimpleDB even simpler than it was before. You can now get started for free. For at least the next six months, you can consume up to 500MB of storage, and you can use up to 25 machine-hours each month. You can transfer 1GB of data in, and another 1GB out," said AWS evangelist Jeff Barr in a blog posting Monday.

Among those using SimpleDB are Pluribo, Issuu, and MyMiniLife.com, Amazon said.

To make SimpleDB easier to use, Amazon said it plans to release a new interface similar to the SQL (Structured Query Language) widely used in databases today. It also plans a mechanism to let people more easily upload multiple items.

BenQ Joybook U101 launches, gives almost no joy

M
The BenQ Joybook Lite U101 we spied back when it was announced in September has just launched, and though there's nothing incredibly exciting here, we thought we'd give you a quick rundown, because we're just cool like that. The U101 boasts completely standard netbook fair -- an Atom N270 CPU, Intel 945GSE chipset, 1GB of DDR2 memory, with 80-160GB mechanical drives and 4-16GB SSD options. It's also got a 16:9 display with a 1024 x 576 resolution (rare for a netbook), a 1.3 megapixel webcam, and three USB 2.0 ports. The sassy little number comes in blue, pink, white and black, and it can be yours for €398 ($503) in Taiwan right now, but we've got no word on when it will be available elsewhere. Dip this puppy in gold or something and then maybe, just maybe we'll bite.

Firefox Surpassing 50% Market Share in More Regions

On top of today’s exceptional news about Firefox surpassing 20% worldwide market share during the month of November, we have further good news to share. After Firefox reached the 50% market share milestone in Indonesia back in July, we can now say the same about two more regions: Slovenia and Macedonia. Below you’ll find the November 2008 numbers according to Net Applications.

What’s the key takeaway here?

Our market share in the regions above has been growing like crazy. For example, since our July announcement about Indonesia, we’ve seen Firefox’s share in Indonesia pick up another 7%, Slovenia 4%, Slovakia 5%, and the Philippines an astounding 13%!

A tremendous amount of credit here goes to the Mozilla community. John Lilly summed it up best: “The open web is more vibrant than ever, and the thousands of Mozilla contributors around the world have played a major role in making it that way.”

Obama-Biden transition site Change.gov now under a Creative Commons license

Change.gov, the website of US president-elect Barack Obama’s transition team, has undergone some important and exciting changes over the past few days. Among them is the site’s new copyright notice, which expresses that the bulk of Change.gov is published under the most permissive of Creative Commons copyright licenses - CC BY.

Except where otherwise noted, content on this site is licensed under a Creative Commons Attribution 3.0 License. Content includes all materials posted by the Obama-Biden Transition project. Visitors to this website agree to grant a non-exclusive, irrevocable, royalty-free license to the rest of the world for their submissions to Change.gov under the Creative Commons Attribution 3.0 License.

This is great news and a encouraging sign that the new administration has a clear sense of the importance of openness in government and on the web (there’s a bit more on this over at Lessig’s blog). The embrace of Creative Commons licensing on Change.gov is consistent with earlier support by both Obama and McCain for the idea of “open debates.” (It’s also in line with Obama’s decision to publish the pictures in his Flickr Photostream under a Creative Commons BY-NC-SA license - pretty cool!)

Tim O’Reilly has written a smart post (which has elicited some very thoughtful reader comments) recommending that Change.gov use revision control as a way to further improve transparency and make it possible for the public to review any changes that occur on the site. Of course, licensing is just one component of openness, but getting licensing right is necessary for enabling people to truly take advantage of technologies that facilitate collaboration.

Update: Several people have pointed out that “works created by an agency of the United States government are public domain at the moment of creation” (see Wikipedia for more on this). Change.gov is not currently the project of a government agency, but a 501(c)(4) that has been set up to manage the Obama-Biden transition. Also, the public is being invited to contribute their own comments and works to the site, and it is important to have a clear marking of the permissions that other people have to this material.

SixApart Hires Pownce Founders, Closes Service


The team behind microblogging service Pownce announced on the company blog today that it is joining blog software company SixApart and closing Pownce in two weeks. Pownce left private beta with a big launch just 11 months ago but the service never grew beyond a core group of fans.

The Pownce team says it plans to "come back with something much better in 2009." We're excited to see what Pownce co-founders Leah Culver and Mike Malone do at SixApart; it should be a very good environment for them to innovate in.

This is the second move where well known innovators have taken their technology and brains to a bigger company and shuttered their startup that we've reported on in a week. Last week open source star Rael Dornfest sold his personal assistant startup Sandy to Twitter.

Though these startups were inspiring, we also think it quite noteworthy that even at a down time economically there are still jobs for super smart people. We covered the Pownce/SixApart deal in greater depth at our hire-tracking site Jobwire. See that coverage for more details about the technology that Pownce will bring to SixApart.

Open source hardware 2008 - The definitive guide to open source hardware projects in 2008

What is open source hardware? Briefly, these are projects that creators have decided to completely publish all the source, schematics, firmware, software, bill of materials, parts list, drawings and "board" files to recreate the hardware - they also allow any use, including commercial. Similar to open source hardware like Linux, but hardware centric.

This is one of the new and emerging trends we've seen really take off over the last few years. Each year we do a guide to all open source hardware and this year there are over 60 projects/kits - it's incredible! Many are familiar with Arduino (now shipping over 60,000 units) but there are many other projects just as exciting and filled with amazing communities - we think we've captured nearly all of them in this list. Some of these projects and kits are available from MAKE others from the makers themselves or other hardware manufacturers - but since it's open source hardware you can make any of these yourself, everything is available.

You can also call this guide... "The Open source hardware gift guide - The one and only, 3rd annual celebration of open source hardware!" - we think these are some of the best things to consider for the holidays and it supports an exciting development in hardware design.

So sit back and get ready to scroll through the list! Here we go!

Windows 7 allows DirectX 10 acceleration on the CPU

Windows 7’s new WARP system can run Direct3D 10 and 10.1 on the CPU, doing away with the need for a hardware 3D accelerator in some circumstances

DirectX CPU It turns out that Intel isn’t the only company that’s looking at performing Direct3D in software; Microsoft has just announced that it’s also planning to introduce a new feature called WARP in Windows 7 that allows you to run Direct3D 10 and 10.1 on the CPU.

In what could be seen as an easy answer to the Vista-capable debacle, where there was some confusion as to what 3D graphics hardware you specifically needed to run Windows Vista’s Aero interface, Microsoft has introduced what it calls a ‘fully conformant software rasterizer’ called WARP (Windows Advanced Rasterization Platform) 10, which does away with the need for a dedicated hardware 3D accelerator altogether.

Microsoft details the new feature in this document on MSDN, in which the company says that WARP 10 will support all the features and precision requirements of Direct3D 10 and 10.1. The feature also supports up to 8x multi-sampled anti-aliasing, anisotropic filtering and all optional texture formats. The minimum CPU spec needed is just a simple 800MHz CPU, and it doesn’t even need MMX or SSE, although Microsoft says that WARP 10 will work much quicker on multi-core CPUs with SSE 4.1.

Of course, software rendering on a single desktop CPU isn’t going to be able to compete with decent dedicated 3D graphics cards when it comes to high-end games, but Microsoft has released some interesting benchmarks that show the system to be quicker than Intel’s current integrated DirectX 10 graphics. Running Crysis at 800 x 600 with the lowest quality settings, an eight-core Core i7 system managed an average frame rate of 7.36fps, compared with 5.17fps from Intel’s DirectX 10 integrated graphics.

Of course, this low level of performance isn’t going to threaten ATI and Nvidia in the world of PC gaming, but it could mean that Windows 7’s 3D desktop interface will now be accessible to everyone, whatever graphics card they own.

Microsoft says that the technology is also targeted at casual games, explaining that ‘the majority of the best selling game titles for Windows are either simulations or casual games, neither of which requires high performance graphics, but both styles of games greatly benefit from modern shader based graphics and the ability to scale on hardware if present.’ Microsoft also points out that the technology could be useful for ‘emulators and virtual environments that are attempting to display advanced 3D graphics.’
