For all the remarkable power of the Internet, some journalists and scholars have worried that it is polarizing society because it’s so easy for Americans to confirm their prejudices by relying on Web sites that share their viewpoints.

“Ideological segregation on the Internet is low in absolute terms,” they conclude in a paper, “Ideological Segregation Online and Offline,” that challenges the work of some other scholars.

The economists do find ideological segregation online is greater than in broadcast and cable TV, magazines and local print newspapers, though they say it’s less than among readers of national print newspapers. From the available data, they find no evidence that the Internet is becoming more ideologically segregated over time.

“Most of the people who visit sites like drudgereport frequented by conservatives or huffingtonpost frequently by liberals , by contrast, are heavy Internet users with a strong interest in politics… who tend to consumer more of everything online ,” they add. “Their omnivorousness outweighs their ideological extremity, preventing their overall news diet from becoming too skewed.”

Then, borrowing a technique used to measure residential racial segregation, they classify sites by the percentage of users who are self-identified conservatives. What’s more, a significant number of people go to many sites.Foxnews scores 88%, meaning that percentage of its users are conservative. Huffingtonpost scores 30%.

Intel’s collaboration With TSMC Temporarily Stranded

Intel this week confirmed that, due to lack of customer demand, with TSMC’s collaboration is temporarily stranded. This means that the two sides will not be released shortly Atom chip jointly developed.

Intel Atom chip business head of the Robert Crucco (RobertCrooke) in an interview said, “I think we are from the cooperation with TSMC gained a lot of important experience for Sony PCGA-BP3T battery . We did not give up, such cooperation will not be quickly see results. ”

About a year ago Intel announced that the company will cooperate with TSMC, producing custom-made chips Ling move. The deal is considered to Intel chips for the growing popularity of custom ARM architecture’s response of Sony PCGA-BP3T battery. Intel and TSMC partnership will allow other companies to customize the chip for Atom.

Analysts pointed out that the on-chip systems market learning curve is very long. Market research firm In-Stat, chief technical strategist Jimumaige McGregor (JimMcGregor) said, “Intel into the system on a chip markets face many challenges, it must move quickly to complete custom design and manufacturing processes according to different products to be adjusted, Intel In this regard there is no advantage. “

Electric Vehicles Help Europe’s Many Factories

Electric vehicles will not only reduce emissions, but may also help to solve another big problem for Europe’s car industry: too many factories  . At least that was the assertion of Carlos Ghosn, chief executive of Renault and Nissan, in a discussion with journalists at the Geneva auto show on Wednesday.

Mr. Ghosn said that Renault and Nissan would be? ahead of the rest of the industry in mass-producing battery-powered vehicles next year and that the new vehicles could help keep the company’s European factories busy. Nissan is planning to produce the battery-powered Leaf at its factory in Smyrna, Tenn.

“In 2011, I’m going to be the only one on the market,” Mr. Ghosn said, dismissing other companies’ electric vehicles as mostly for show. “The numbers are big. I think there’s going to be a need for new capacity”Renault has more factories than it needs  . But Mr. Ghosn said it would be easier to produce components like electric motors and batteries in Europe competitively than it would be to produce conventional vehicles.

He said the French government had already ordered 100,000 battery-powered cars, and the start-up Better Place had ordered another 100,000 over several years. Better Place plans to allow users to swap in freshly charged batteries at a network of stations in Israel and Denmark.Battery last raised a fund in 2007, a $750 million effort , . With the new fund under its wing, Battery has raised nearly $4 billion since its inception.

Mr. Ghosn conceded that true demand for electric vehicles won’t be known until they are on the market. But he said surveys showed that more than 8 percent of car owners in the United States, Europe and Japan said they want their next vehicles to be electric.At various points in its history , Battery’s portfolio has included a litany of companies that have since been acquired or gone public.

the ISuppli Corporation,which thin-film solar cells are quickly captured in market share in Crystal Technology, until 2013, the PV-part well be more than twice as many watts. By 2013, solar panels on the global market will be increased from 14% to 31%.

“First Solar is a strong proof of the viability of thin-film market, the company grew this year, the world’s largest manufacturer of solar cells, more than one billion watts .” ISuppli GregSheppard research director, said: “At the same time, the company has already per-watt, the cost of production is less than 90 cents a silicon crystal is about half of the engine manufacturer.”

Most solar cells made from crystalline silicon, polysilicon, with 180-230 microns. On the contrary, thin-film panels by the deposition of multi-layer substrate made of other materials, the thickness of a few micrometers . The main difference between the two technologies lies in the efficiency and the cost of electricity per watt. Thin-film panels in the sunlight into electricity less efficiently, but the production costs are significantly lower.

It is remarkable that the film is limited in space at a disadvantage, such as residential roofing. Film installation may require more space for 15-40% of crystalline silicon account in order to reach it with the overall system performance . This tends to limit its activities to make certain applications to more attractive.

Thin-film modules are expected next year, the average price drop to $ 1.40, $ 1.70 lower than in 2009. In 2010, the average price of crystalline silicon panels are expected to be $ 2.00, falling $ 2.50 this year.ISuppli Corporation predicts that by the end of 2012, made from crystalline silicon to a certain extent, reduce the price because the providers are financially strong, they stay in investment, technological development and has invested heavily in improving production processes.

Beijing is planning a battery-leasing company specifically engaged by it prepared for the battery, it’s like-for-home cylinders, the user, where it is going to change  , and only charge rent, so within three five minutes you can remove the original battery to replace the battery for a good one.

It is understood that this lease is not only the battery can be easily and quickly replaced, but also for motorists, and also significantly reduce costs.It is the time for the procurement of vehicles, not including the value , I just the cost of procurement of vehicles, you can be even cheaper than conventional car, because it is not the driving force.

According to the report by the Beijing Automotive R & D is of pure electric vehicles in the first half of this year, the first taxi and government officials, and launchers, until the end of 2010 is expected to be launched 30 Cikuan pure electric cars  , as an opportunity , electric car production capacity will be developed quickly.

In April this year we will launch the first-replaceable battery electric cars, like cars, we plan to start by the end of the 30, and later expand it gradually and expects its production by 2015, to our new energy company’s production capacity to 150,000 fulfill.

We insist on Dell’s commitment to cooperate fully with the practice of reducing the emissions of some , but also hope that other companies and organizations can provide a model for this world-class learning environment. “

When you open the computer ,suddenly found much noise from the tractor .Is it bad ? No, the winter came, and the computer is in a warm private.Guessed it, then my friends in these days and is estimated by searching for a busy winter clothing, is it? Yes, people want to spend the winter, today, then how is the notebook of VGP-BPS13?

Cold temperatures for our beloved laptops represent a particular threat. Then, piercing winds, large Xue Piaopiao the arrival of winter, even in the cold winter months, as we should beloved notebook computer  ? In winter, the note of the work, the use of laptop computers?

Laptops are very afraid of the cold. This is the first notebook screens are hurt low-temperature, the notebook LCD screens generally the best use of the temperature of 40 degrees Celsius to 10 degrees Celsius (computer self-temperature) in this temperature range for Dell latitude d600 battery , unusual color TFT screen, it the aging process is accelerated when too low a temperature range from the use of TFT screen can dead pixels, re-TFT screen is displayed, causing permanent damage.

Followed by the low temperature Laptop Batteries injured. Most notebook computers now with lithium batteries, the battery has the advantage of large capacity, but also brought the shortcomings of this very cool. General Civil Li-ion battery like Dell latitude d610 battery, to be at zero degrees Celsius, if the capacity would be reduced by 20%, if the capacity can reach minus 10 degrees Celsius, only about half.

The North’s friends all know that if cell phone can be placed without electricity in winter and warm in a warm arms that are used for a period of time for VGP-BPS13, because the battery is too low because of the temperature caused by an electrical discharge with no success is.
