Google is hoping to dissuade the Department of Justice from bringing an antitrust case.


Increasing scrutiny of corporate behavior, Google is hoping to dissuade the Department of Justice from bringing an antitrust case.
For several months, Google has been explaining to regulators and journalists that, contrary to the predatory image painted by competitors, the company is fragile. It has made its case in Washington, D.C., New York, and Brussels, hoping to dissuade the U.S. Department of Justice and European regulators from bringing an antitrust case against the company.

After the lax regulatory atmosphere of the Bush administration, the Obama administration appears to be increasing its scrutiny of corporate behavior. The new head of the Justice Department's antitrust division said in a recent speech that the department would be taking a more aggressive approach with companies that use their dominant position to stifle competition. In a speech last year, before her appointment to the Justice Department, she said that Google had acquired a monopoly in online advertising.
Google also faces Justice Department scrutiny over its proposed settlement with book publishers and authors, Federal Trade Commission scrutiny over board members who also serve on Apple's board, and a Justice Department inquiry into the possibility that Silicon Valley companies such as Google and Apple colluded to avoid poaching employees from one another. Last year, Google abandoned a planned advertising deal with Yahoo to avoid an antitrust showdown with the Justice Department.

During the Google presentation, Adam Kovacevich, the company's senior manager of global communications and public affairs, acknowledged that the company's success has brought increased scrutiny. But he insisted that Yahoo (NSDQ: YHOO) was in a similar position a decade ago, citing a 1998 Fortune article that declared, "Yahoo has won the search engine wars."

"We also know our position is fragile," he said.
In keeping with Google's emphasis on data and metrics, Google legal counsel Dana Wagner, who coincidentally used to work in the antitrust division of the Justice Department, offered an anecdote in support of this claim.

Microsoft is adding a "Windows XP Mode" to Windows 7


Now Windows 7 gets built in XP mode..
Microsoft is adding a "Windows XP Mode" to Windows 7, in a move to encourage users to make the switch to the software vendor's forthcoming operating system.

The firm has built its XP mode into Windows 7 by using the Windows Virtual PC technology Microsoft acquired in 2003, to make the OS compatible to run apps designed for Vista's predecessor.
Redmond was keen to emphasise in a blog post late on Friday that it's hoping to woo small businesses to move to Windows 7 by bigging up the XP mode feature.

"Windows XP Mode is specifically designed to help small businesses move to Windows 7," said Microsoft. "Windows XP Mode provides you with the flexibility to run many older productivity applications on a Windows 7 based PC."

Users can install apps directly into the virtualised XP environment. The applications are then published to the Windows 7 desktop and they can be run from within that OS.

Microsoft said it will release a beta of Windows XP mode and Windows Virtual PC for Windows 7 Professional and Windows 7 Ultimate "soon" but wasn't more specific about when the test builds will land.

When Microsoft released Vista over two years ago, many businesses and individuals complained about compatibility snafus with applications that simply wouldn't work within the new OS

Apple unveiled the new iPod Shuffle


Apple iPod Shuffle....
Apple unveiled the new iPod Shuffle, which is only half the volume of the previous iPod Shuffle, which itself was about the size of a quarter. The new one looks like a sleek aluminum tie clip, or maybe a slightly elongated stick of Trident gum; a AA battery hides it completely. There's just enough room on the back for a mirror-finish spring clip for fastening to your clothes. (If you order from apple.com, you can get a custom message laser-etched onto the clip.)
Apple's third-generation iPod Shuffle MP3 player ($79) is the smallest MP3 player you can buy. Its unique size and uncommon, remote-controlled design won't suit every purpose, but people looking for the next best thing to an invisible iPod will appreciate the player's minimal approach.

Design

At first glance, the iPod Shuffle looks almost like a practical joke--as if someone is trying to convince you that their tie clip plays MP3s. The aluminum-encased hardware measures just a few hairs larger than a paper clip (0.7 inch by 1.8 inches by 0.3 inch) and includes not a hint of button, knob, or screen. The headphone jack sits on the top edge of the Shuffle along with a switch that controls playback mode (shuffle playback/consecutive playback) and power.

Fortunately, Apple doesn't expect you to control the Shuffle's volume and playback using mind control (not yet, at least). The earbud-style headphones bundled with the Shuffle include a remote control on the cable, just below the right ear. The remote offers three buttons: two for volume control (up/down); and a central button with multiple functions. You press the center button once to pause music playback, twice to skip forward, and three times to skip back. Of course, the downside to this headphone-controlled design is if you lose your headphones, you also lose control of your iPod. Apple's own replacement earbuds for the Shuffle run $29, but it's possible to grab third-party headphones and adapters for less.
The headphone cable reaches 3 feet, which should be more than enough length considering that the Shuffle is meant to be clipped to your clothing. A hinged chromed metal clip runs the length of the Shuffle on one side and includes a slot for attaching a lanyard or keychain. An Apple logo is engraved on the clip, and custom engraving is offered on orders placed through Apple's online store.

Features

The Shuffle is purely a digital audio player. There's no FM radio, no voice recording, and--obviously--no photo or video playback. Audio formats supported include MP3, AAC, Audible, WAV, AIF, and Apple Lossless, but no hope for WMA or FLAC.

The third-generation version of the iPod Shuffle offers a few new features over previous models, though. For one, this is the first Shuffle that tells you what you're listening to, which is no small accomplishment considering the player doesn't have a screen. The Shuffle uses a synthesized voice to announce artist and song title information whenever you hold the headphone clicker down. Apple is calling this feature VoiceOver and offers support for 14 languages, with voice quality hinging on what type of computer and operating system you're using.

First robotics contest Makes Science chill!

Robot No. 219 was designed and built by Warren Hills Regional High School students in six weeks.

High School students participate in FIRST robotics competition.
Blair Robot Project competes at Washington, D.C.
regional.Blair team already preparing for tough future competitions.The Blair Robot Project placed 23rd among 65 participating teams at the 2009 FIRST FRC (For Inspiration and Recognition of Science and Technology Robotics Competition) Washington, D.C. regional in the Walter E. Washington Convention Center on Feb.

The FRC challenges students around the country with a game design from which teams have six weeks to assimilate their engineering, programming and constructing skills into a robot to accomplish the game's objectives. This year's game, "Lunacy," required team robots to work in alliances to score balls into baskets attached to opposing robots while driving around on a slick arena track.

With four wins and three losses in the qualification matches at the D.C. regional, Blair was not picked to move on to elimination matches, the next step of the competition. Problems attributed to the camera sensor detecting for the robot's shooter hindered the team from scoring. The shooter ended up calculating the distance and power needed to score too slowly at the competition since all targets were moving, according to senior member William Shepherdson.

The team plans to participate again at the Chesapeake regional on March 19. "We can bring 40 pounds of parts and things we build to modify our robot for Chesapeake," Shepherdson said. "We want to retweak the code a bit and are thinking about redoing our scoring mechanism." Teams from the winning alliance of each regional competition move on to the national championship in Atlanta, Ga. on April 16.

The Blair Robot Project, sponsored by physics teacher Joseph Boettcher and computer science teacher Mary McManus, began the build season on Jan. 3 by dividing and conquering their task through smaller groups - electronics, programming, drive, specialty and public relations. Three thousand dollars in parts, $9,000 in prototyping and hundreds of hours of work later was a 119-pound, five-foot tall robot complete with an automated-camera controlled turret shooter and a smooth drive system. "Some of the most dedicated members put in over 200 hours over build season," junior vice president Eric Van Albert said

Universal Music Group & Google to create a joint music video venture.



Universal, Google in talks about music video partnership..Google Inc. and Universal Music Group are in talks to enter a partnership that would create a new music video hub powered by YouTube, according to a report in The Wall Street Journal .
Under the partnership, Universal would use YouTube technology and ad sales to distribute content around the Web.

when Google-owned YouTube is searching for ways to monetize its vast amounts of video content and Internet traffic. The major record labels have also been exploring a number of online strategies for monetizing their music content as compact disc sales continue their steep decline.

Google (Nasdaq: GOOG) paid $1.65 billion for YouTube a few years ago.
Google's stock was down 4 percent to US$306.10 per share in mid-day trading on Thursday.
No deal has been officially announced by YouTube or Universal Music Group yet.


YouTube and Universal Music are reportedly trying to hash out a deal to create a premium music video site. Currently, many music videos can be found on YouTube, but a deal with one or more major record companies could create a more easily monetized and managed music video portal. YouTube may be looking at the model followed by Hulu, which pairs professional TV content with video advertisements.
Moving away from the current model of labels receiving licensing fees or a share of ad revenue for their videos, Universal wants a new relationship in which music videos are displayed in "high-quality" and are ad-supported. The site would be separate from YouTube's main site.

Google has also notified Warner Music Group, Sony and EMI about the plans but they are not part of the current negotiations.

The talks are still in their preliminary stages, despite beginning in January.

Universal CEO Doug Morris is said to be at the head of the talks and the move makes sense being that Universal's licensing agreement with YouTube is set to expire on March 31st.

The Universal Music Group channel on YouTube is by far its most popular, generating 3.6 billion views so far.

Nokia announced the new Nokia 5800 Xpress Music's availability in the United States


Challenging the iPhone is apparently easier said than done. RIM’s Blackberry Storm has plenty of software and interface issues, SonyEricsson’s Xperia X1 is way too expensive and those who hoped that Nokia’s 5800 phone would provide a contract-free alternative may be disappointed as well. The phone came with faulty earpiece speakers and cannot find AT&T’s 3G network, prompting Nokia to remove the phone from store shelves again.

Technical problems with the U.S. version of the newly launched Nokia 5800 music mobile phone have led flagship stores in New York and Chicago to pull the model, according to PC World. For now, U.S. customers have to settle for a European version instead.
Positioned as a rival to Apple's iPhone, the phone is a music device with a touch-screen interface, priced at $399 before taxes and subsidies in the U.S.
But according to PC World, the U.S. launch has been interrupted by consumer complaints that the earpiece is not properly protected against moisture, which ruins the speaker. Users have also reported difficulties connecting to AT&T's 3G network, and many customers have reportedly already returned their phones.

Following its introduction in October 2008, the Nokia 5800 Xpress Music has seen successful sales in a number of markets, including Hong Kong and Moscow, where the device sold out within hours of the sales kickoff, Nokia said.

Many consumers have returned their 5800s to the Nokia stores in Chicago and New York, which eventually convinced Nokia to stop selling the phone for now. Nokia did not say how many 5800s have been sold in the U.S.

Meanwhile there is also talk about Nokia’s Comes with Music service, a major selling point of the 5800, which was promised to allow users unlimited access to the service’s entire music library one year free of charge.
U.S. launch likelihood: Very Strong.

U.S. consumers are already watching broadcast TV shows on free websites such as Hulu.com,



"OnDemand Online" will be available free to Comcast cable TV subscribers, Business Insider reports. That means only customers inside Comcast's cable zone can sign up, but the service itself is available anywhere. For example, a user could still watch on demand videos away from home (the company is working on a way to verify subscriptions). Also of note, the service would count against Comcast's 250 GB monthly bandwidth cap.

The major difference between this service and Hulu is content. While Hulu's videos come from NBC, Fox and their cable channels like FX, Comcast is inking deals with other cable networks, possibly providing a streaming opportunity for channels like the Food Network and Discovery. In other words, Comcast is going to focus on content that isn't already online.

Because Comcast and other cable providers pay fees that account for roughly half of cable channels' revenue, it's in the channels' best interests to keep providers healthy, Business Insider notes. By comparison, hardly any money comes in through online viewing, so its more likely for a channel to give its content to Comcast than to an online-only service like Hulu.
U.S. cable, programmers set for Web TV by summer,,,
Cable and satellite TV providers are working on a free online video service to deliver up-to-date cable shows to computers and mobile phones, but the industry is worried the project could cannibalize pay-TV's long-standing revenue model.
cable network programing is available primarily on cable and satellite TV services, such as Comcast Corp (CMCSA.O) and DirecTV Group Inc (DTV.O), or nascent video services from phone companies.
This is about bringing new amounts of content to the Internet in a business model that continues to support the creation of that content," said Sam Schwartz, executive vice president of Comcast Interactive Media.

Comcast is leading talks with programmers like Viacom Inc (VIAb.N) and Discovery Communications Inc (DISCA.O), with Time Warner Cable (TWC.N), DirecTV and others involved. Their plans are at different stages, and cable operators will likely discuss putting cable programing online at an industry meeting this week according to people familiar with the plans.

The project would let cable and satellite TV subscribers watch up-to-date cable shows on the Web, and possibly on mobile phones, for free possibly as soon as this summer, the sources said.

The idea is to give customers added flexibility to view their favorite shows. It is also seen as a preemptive strike against possible 'cord-cutting' of video services, particularly by younger subscribers used to watching other programs online.

But the project presents a number of business and technology challenges to both operators and programmers.

Cable programmers like Viacom's MTV Networks make money from advertising sales, as well as affiliate fees that cable and satellite TV service providers pay.

TECHNOLOGICAL ISSUES

Whatever business models are agreed upon will depend to some extent on overcoming technological challenges.

One involves identifying which customers have the right to view a show, and managing digital rights to avoid over-wide distribution. There is also the need to accurately 'time' the content so it is available to users for a restricted period -- so as not to jeopardize other media content distribution systems such as video on demand and DVD releases.

Yet executives also acknowledge the risk of ignoring the Web, as seen by the music and newspaper industries that have suffered as consumers change their media consumption habits.

Comcast sees the project, which it calls On Demand Online, as a natural progression from digital video recorders and video-on-demand channels.

It is working on technology to authenticate subscribers who go to Comcast's Fancast and Comcast.net websites for video. This would effectively create a "wall" behind which programmers might feel comfortable keeping some of their premium shows.

Offline web applications allow people to store data on their own computer


Working offline can come with an unexpected risk
A security expert has sounded a warning on features that allow offline access to websites. so that they can use services like web-based e-mail when not online.
Be cautious when you get an email that says "there's a problem with your password, click on this link and we'll fix it"
But sites with poor security that use the feature put their visitors at risk of being robbed of their data.

Michael Sutton disclosed the threat at the Black Hat security conference in Washington, DC.

Offline web applications are taking off because of services such as Gears, developed by Google, and HTML 5, a new HTML specification that is still in draft form.

It was introduced to many web users in January, when Gmail introduced a Gears-powered offline mode. Offline Gmail lets users read and write e-mail when they're not connected to the internet.

Mr Sutton stressed that Gmail, Gears and HTML 5 are considered secure, but websites that implement offline features without proper security could put users at risk.

"You can take this great, cool secure technology, but if you implement it on an insecure website, you're exposing it. And then all that security is for naught."

Mr Sutton found that websites which suffer from a well-known security vulnerability known as cross-site scripting are at risk.

A hacker could direct a victim to a vulnerable website and then cause the user's own browser to grab data from their offline database.
Unlike phishing, the whole attack could take place on a reputable site, which makes it harder to detect.

As a proof of concept, Mr Sutton was able to swipe information from the offline version of a time-tracking website called Paymo. Mr Sutton alerted Paymo and it fixed the vulnerability immediately.

Web developers must ensure that their sites are secure before implementing offline applications, said Mr Sutton.

"Gears is fantastic and Google has done a great job of making it a secure technology. But if you slap that technology into an already vulnerable site, you're leaving your customers at risk," he explained.

Security expert Craig Balding agreed that it was up to developers to secure their sites, as the line between desktop applications and web applications becomes more blurred.

"Every website wants to keep up in terms of features, but when developers turn to technologies like this they need to understand the pros and cons," he told BBC News.

cybercrime is rising sharply, experts have warned at the World Economic Forum in Davos.


Cybercrime threat rising stridently.
The threat of cybercrime is rising sharply, experts have warned at the World Economic Forum in Davos.

They called for a new system to tackle well-organised gangs of cybercriminals.

Online theft costs $1 trillion a year, the number of attacks is rising sharply and too many people do not know how to protect themselves, they said.

The internet was vulnerable, they said, but as it was now part of society's central nervous system, attacks could threaten whole economies.

The past year had seen "more vulnerabilities, more cybercrime, more malicious software than ever before", more than had been seen in the past five years combined, one of the experts reported.

But does that really put "the internet at risk?", was the topic of session at the annual Davos meeting.

On the panel discussing the issue were Mozilla chairwoman Mitchell Baker (makers of the Firefox browser), McAfee chief executive Dave Dewalt, Harvard law professor and leading internet expert Jonathan Zittrain, Andre Kudelski of Kudelski group, which provides digital security solutions, and Tom Ilube, the boss of Garlik, a firm working on online web identity protection.

They were also joined by Microsoft's chief research officer, Craig Mundie.

To encourage frank debate, Davos rules do not allow the attribution of comments to individual panellists

Threat #1: Crime

The experts on the panel outlined a wide range of threats facing the internet.
There was traditional cybercrime: committing fraud or theft by stealing somebody's identity, their credit card details and other data, or tricking them into paying for services or goods that do not exist.

The majority of these crimes, one participant said, were not being committed by a youngster sitting in a basement at their computer.

Rather, they were executed by very large and very well-organised criminal gangs.

One panellist described the case of a lawyer who had realised that he could make more money though cybercrime.

He went on to assemble a gang of about 300 people with specialised roles - computer experts, lawyers, people harvesting the data etc.

Such criminals use viruses to take control of computers, combine thousands of them into so-called "botnets" that are used for concerted cyber attacks.

In the United States, a "virtual" group had managed to hijack and redirect the details of 25 million credit card transactions to Ukraine. The group used the data to buy a large number of goods, which were then sold on eBay.

This suggested organisation on a huge scale.

"This is not vandalism anymore, but organised criminality," a panellist said, while another added that "this is it is not about technology, but our economy".

Threat #2: the system

A much larger problem, though, are flaws in the set-up of the web itself.

It is organised around the principle of trust, which can have unexpected knock-on effects.

Nearly a year ago, Pakistan tried to ban a YouTube video that it deemed to be offensive to Islam.

The country's internet service providers (ISPs) were ordered to stop all YouTube traffic within Pakistan.
However, one ISP inadvertently managed to make YouTube inaccessible from anywhere in the world.

But in cyberspace, nobody is responsible for dealing with such incidents.

It fell to a loose group of volunteers to analyse the problem and distribute a patch globally within 90 minutes.

"Fortunately there was no Star Trek convention and they were all around," a panellist joked.

Threat #3: cyber warfare

Design flaws are one thing, cyber warfare is another.

Two years ago, a political dispute between Russia and Estonia escalated when the small Baltic country came under a sustained denial-of-service attack which disabled the country's banking industry and its utilities like the electricity network.
This was repeated last year, when Georgia's web infrastructure was brought down on its knees during its conflict with Russia.

"2008 was the year when cyber warfare began.. it showed that you can bring down a country within minutes," one panellist said.

"It was like cyber riot, Russia started it and then many hackers jumped on the bandwagon," said another.

This threat was now getting even greater because of the "multiplication of web-enabled devices" - from cars to fridges, from environmental sensors to digital television networks.

The panel discussed methods that terrorists could use to attack or undermine the whole internet, and posed the question whether the web would be able to survive such an assault.

The real problem, concluded one of the experts, was not the individual loss.

It was the systemic risk, where fraud and attacks undermine either trust in or the functionality of the system, to the point where it becomes unusable.



What solution?

"The problems are daunting, and it's getting worse," said one of the experts. "Do we need a true disaster to bring people together?," asked another.

One panellist noted that unlike the real world - where we know whether a certain neighbourhood is safe or not - cyberspace was still too new for most of us to make such judgements. This uncertainty created fear.

And as "the internet is a global network, it doesn't obey traditional boundaries, and traditional ways of policing don't work," one expert said.

Comparing virus-infected computers to people carrying highly infectious diseases like Sars, he proposed the creation of a World Health Organisation for the internet.

"If you have a highly communicable disease, you don't have any civil liberties at that point. We quarantine people."

"We can identify the machines that have been co-opted, that provide the energy to botnets, but right now we have no way to sequester them."

But several panellists worried about the heavy hand of government. The internet's strength was its open nature. Centralising it would be a huge threat to innovation, evolution and growth of the web.

"The amount of control required [to exclude all risk] is quite totalitarian," one of them warned.

Instead they suggested to foster the civic spirit of the web, similar to the open source software movement and the team that had sorted the YouTube problem.

"Would a formalised internet police following protocols have been able to find the [internet service provider] in Pakistan as quickly and deployed a fix that quickly?" one of them asked.

How Soon Will Cybercrimes Be Punished?
In criminal offenses, there would be no crime when there is no law punishing it. That explains why various crimes done through the internet still persist these days. In cases where the offenders are caught, court proceedings won't go so well because only the part of the offense which is governed by the Revised Penal Code (RPC) is being litigated. The main bulk of the offense, the cybercrime, is usually left untouched. This is the main issue; yet, the current RPC is still inadequate to deal with such matter. Hence, the government's highest monitoring body for the conditions and status of Information Technology in the Philippines is now putting pressure on the legislature to propose a bill against cybercrimes.
The Commission on Information and Communication Technology (CICT) define cybercrimes as those offenses done in the realm of the internet which, just like usual offenses, have grave and concrete effects to the ones who are affronted. The crimes identified are hacking, identity theft, phishing, spamming, website defacement, denial-of-service (DoS) attacks, malware or viruses, child pornography, and cyber prostitution. Such crimes are not yet punishable under the country's criminal law. That is why there is a need for a legislative action to eventually make each of the aforementioned offenses become a felony in order for perpetrators to be punished in accordance with the law.
CICT is very hopeful that increased awareness and support will push the Congress to finally pass a bill against cybercrimes. The commission endorsed the "Cybercrime Prevention Act of 2008" wherein four cyber-related bills authored by different lawmakers are consolidated. A representative from the Council of Europe, an organ of the European Council, also joined the technical working group in refining the bill a year prior to the endorsement. Such representation is meant to "harmonize" the bill with European standards on cybersecurity. It has to be considered that such crimes are not solely confined to one nation but rather that they traverse territorial boundaries considering that the crimes are committed in the World Wide Web..
Currently, CICT feels that there is an increasing support from private sector groups. The Business Process Association of the Philippines (B/PAP) which represents the outsourcing industry is an example. The said umbrella organization supports such bill because it infers that once the country is secured from different forms of cybercrimes through existing and enforceable laws, it would be easier to sell the services that are done in the country to foreign investors. The bill would ensure that the clients are well covered when we speak of cybersecurity in the Philippines.
With these, it can be said that the current conditions the country is facing calls for progressive and up-to-date legislations. Neighboring countries like Singapore and Malaysia have already adopted such measure. Unluckily though, the bill is hampered by the other so called "more important" considerations discussed in both Lower and Upper House of the Congress in the Philippines. It is already five years since the bill was endorsed, yet, the Congress still fails to accommodate it. While increased support and awareness regarding cybercrimes becomes more apparent, hopefully ,the legislature will finally act on this issue.

Solar power a ventilation system that can cool the car without help from the engine.


Solar cars still a way off

Toyota's third-generation Prius, due at dealerships this spring, will have an optional solar panel on its roof. The panel will power a ventilation system that can cool the car without help from the engine, Toyota says.
But it's a long way from the 2010 Prius to a solar-powered car, experts told CNN. Most agree that there just isn't enough space on a production car to get full power from solar panels.

"Being able to power a car entirely with solar is a pretty far-reaching goal," said Tony Markel, a senior engineer at the federal government's National Renewable Energy Lab in Golden, Colorado.


In the new Prius, the solar panel will provide energy for a ventilation fan that will help cool the parked car on sunny, hot days. The driver can start the fan remotely before stepping into the car. Once the car is started, the air conditioning won't need as much energy from a battery to do the rest of the cooling.


"The best thing about using solar is that regardless of what you end up using it for, you're trying to use it to displace gasoline," added Markel.


The question is, how much gasoline can solar power offset? Markel said his lab has modified a Prius to use electricity from the grid for its main batteries and a solar panel for the auxiliary systems. He believes the car gets an additional 5 miles of electric range from the panel.
According to recent articles in Japan's Nikkei newspaper, Toyota has bigger plans for harnessing power from the sun. Nikkei reports that Toyota hopes to develop a vehicle powered entirely by solar panels. The project will take years, the paper reported.


When contacted by CNN, however, a Toyota spokeswoman denied the existence of the project.


"At this time there are no plans that we know of to produce a concept or production version of a solar-powered car," said Amy K. Taylor, a communications administrator in Toyota's Environmental, Safety & Quality division.


Motorists don't have to wait for a 2010 Prius to drive a solar-enhanced car, however. Greg Johanson, president of Solar Electric Vehicles in Westlake Village, California, said his company makes a roof-mounted panel for a standard Prius that enables the car to travel up to 15 additional miles a day.


The system costs $3,500, and it takes about a week to make one, Johanson said. Billy Bautista, a project coordinator at the company, said Solar Electric Vehicles gets so many requests for the system that there is a backlog of several months.


The company's Web site says motorists can install the panels themselves, although it recommends finding a "qualified technician."


The system delivers about 165 watts of power per hour to an added battery, which helps powers the electric motor, Johanson said.


But others said it would take a lot more power than that to replace an internal combustion engine.


Eric Leonhardt, director of the Vehicle Research Institute at Western Washington University, said that even if solar cells worked far better than they do today, they wouldn't generate enough power for driving substantial distances. The best cells operate at about 33 percent efficiency, but the ones used on vehicles are only about 18 percent efficient, he said.


Leonhardt said it would be more practical to use solar power to help charge a car's battery and use the more efficient panels mounted on a roof or over a parking area to supply the rest of the electricity needed to drive the engine.


"Solar panels really need a lot of area," he said.


Leonhardt thinks Toyota's new Prius is a good first step toward using renewable energy. Some cars get hotter than 150 degrees inside when parked in the sun, so reducing the temperature could mean Toyota could use a smaller AC unit, he added.


Johanson of Solar Electric Vehicles said he'd like to see Toyota bring the weight of a Prius down from 3,000 pounds to 2,000. He also hopes for a small gasoline engine and a larger electric motor. That will probably come in the future, when Toyota unveils a plug-in engine.


In the meantime, Solar Electric Vehicles sells its version of a plug-in Prius, with a solar panel installed, for $25,000, Bautista said.


Toyota is the largest automaker to incorporate solar power into a mass-produced car. But its solar panel is not the first for a car company. Audi uses one on its upscale A8 model, and Mazda tried one on its 929 in the 1990s.


In addition, a French motor company, Venturi, has produced an electric-solar hybrid. The Eclectic model costs $30,000, looks like a souped-up golf cart and uses roof-mounted solar panels to help power an electric engine. It has a range of about 30 miles and has a top speed of about 30 mph.



ABOUT Solar vehicle


Borealis III leads the way during the 2005 North American Solar Challenge passing by Lake Benton, Minnesota.A solar vehicle is an electric vehicle powered by a type of renewable energy, by solar energy obtained from solar panels on the surface (generally, the roof) of the vehicle. Photovoltaic (PV) cells convert the Sun's energy directly into electrical energy. Solar vehicles are not practical day-to-day transportation devices at present, but are primarily demonstration vehicles and engineering exercises, often sponsored by government agencies.


Solar cars
Solar cars combine technology typically used in the aerospace, bicycle, alternative energy and automotive industries. The design of a solar vehicle is severely limited by the energy input into the car (batteries and power from the sun). Virtually all solar cars ever built have been for the purpose of solar car races (with notable exceptions).


Like many race cars, the driver's cockpit usually only contains room for one person, although a few cars do contain room for a second passenger. They contain some of the features available to drivers of traditional vehicles such as brakes, accelerator, turn signals, rear view mirrors (or camera), ventilation, and sometimes cruise control. A radio for communication with their support crews is almost always included.


Solar cars are often fitted with gauges as seen in conventional cars. Aside from keeping the car on the road, the driver's main priority is to keep an eye on these gauges to spot possible problems. Cars without gauges available for the driver will almost always feature wireless telemetry. Wireless telemetry allows the driver's team to monitor the car's energy consumption, solar energy capture and other parameters and free the driver to concentrate on just driving.


Electrical and mechanical systems
The electrical system is the most important part of the car's systems as it controls all of the power that comes into and leaves the system. The battery pack plays the same role in a solar car that a petrol tank plays in a normal car in storing power for future use. Solar cars use a range of batteries including lead-acid batteries, nickel-metal hydride batteries (NiMH), Nickel-Cadmium batteries (NiCd), Lithium ion batteries and Lithium polymer batteries.


Many solar race cars have complex data acquisition systems that monitor the whole electrical system while even the most basic cars have systems that provide information on battery voltage and current to the driver.


The mechanical systems of a solar car are designed to keep friction and weight to a minimum while maintaining strength. Designers normally use titanium and composites to ensure a good strength-to-weight ratio.


Solar cars usually have three wheels, but some have four. Three wheelers usually have two front wheels and one rear wheel: the front wheels steer and the rear wheel follows. Four wheel vehicles are set up like normal cars or similarly to three wheeled vehicles with the two rear wheels close together.

Internet Explorer 8 Focuses on better Security and Privacy

Some of the features of liberate Candidate 1, now existing to the public, are similar to functionality that’s already included in Firefox 3.
Microsoft's updated browser, Internet Explorer 8, promises an assortment of new features designed to help make Web browsing with IE safer, easier, and more compatible with Internet standards. We looked at the first release candidate of the new browser released to the public today, Release Candidate 1 (RC1). On the surface, IE 8 seems to be a lot like IE 7, but Microsoft has made a number of changes under the hood. You may have seen some of these new features already, however, in IE's no-longer-upstart competitor, Mozilla Firefox 3.
Tabbed Browsing

If you accidentally close a browser window in IE 8, you can opt to restore it when you reopen the program (just as you can in Firefox). IE 8 will use color coding to group related tabs together. If you open a link from pcworld.com in a new tab, for example, it will open adjacent to the original tab, and the tabs themselves will have a matching color. You can move tabs from one group to another, but if you have three unrelated pages open, you cannot create a group out of them.
Perhaps the most novel addition in IE 8 is what Microsoft calls tab isolation. The feature is designed to prevent a buggy Web site from causing the entire Web browsing program to crash. Instead, only the tab displaying the problematic page will close, so you can continue browsing.
Of course, IE 8 RC1 retains some of the features introduced in the first beta, including WebSlices and accelerators; see "Updated Web Browsers: Which One Works Best?" for more details.
Searching

IE 8 can use multiple search engines besides Windows Live Search, and you can add other search engines to the mix. Also, IE 8 will give you search suggestions as you type. For example, I can type in 'PC World' into the search field, and IE 8 RC1 will give me Live Search suggestions such as 'pc world magazine' or 'pc world reviews'. In addition, IE 8 lets you switch between search engines on the fly by clicking an icon at the bottom of the search field's drop-down menu. IE 8 can search Yahoo and Ask.com, and you can install add-ins that give IE 8 the capability to search Wikipedia, Amazon, and the New York Times, among other sites.
Improved Security
Microsoft touts IE 8 as its most secure browser to date, and Microsoft has indeed added a good number of security features to the mix, ranging from phishing detection to private browsing, plus a new feature to prevent clickjacking, an emerging data theft threat.
IE 8 RC1 includes two security features under the 'InPrivate' label: InPrivate Browsing and InPrivate Filtering. Both existed in earlier prerelease versions of IE 8, but IE 8 RC1 lets you use the two features separately, whereas before each relied on the other.
If you enable IE 8's InPrivate Browsing feature, the browser will not save any sensitive data--passwords, log-in info, history, and the like. Afterward it will be as if your browsing session had never happened. This feature is very similar to Private Browsing in Apple's Safari browser, except that an icon in IE's address bar makes InPrivate Browsing's active status more obvious.
InPrivate Filtering--called InPrivate Blocking in earlier IE 8 builds--prevents sites from being able to collect information about other Web sites you visit. This feature existed in IE 8 Beta 2, but you could use it only while using InPrivate Browsing. In RC1, you can use InPrivate Browsing at any time.
The browser's phishing filter--called SmartScreen--improves on its predecessor's filter with such features as more-thorough scrutiny of a Web page's address (to protect you from sites named something like paypal.iamascammer.com) and a full-window warning when you stumble upon a suspected phishing site. SmartScreen relies largely on a database of known phishing sites, so new, unknown phishing sites may slip through the cracks.
IE 8 displays sites' domains in a darker text color, so you can more readily see whether you're visiting a genuine ebay.com page, say, or a page simulating an eBay page on some site you've never heard of. Microsoft could still put a little more emphasis on the domain name (using a different color background, for example), but the highlighting is a welcome addition.
Finally, IE 8 RC1 includes a feature designed to prevent clickjacking, a method in which Web developers insert a snippet of HTML code into their Web page code to steal information from Web page visitors. When you use IE 8 to view such a page, IE 8 can identify an attempted clickjacking and will warn you of the attempt.
Web Compatibility
Creating a site that looks identical in Internet Explorer, Firefox, and Safari can be a challenge. IE 8 Beta 2 offers better support for W3 Web standards--a set of guidelines developed to ensure that a Web page appears the same in all browsers. The downside is that IE 8 will break some pages designed for earlier Internet Explorer versions.
To counteract this problem, Microsoft has added a compatibility mode: Click a button in the toolbar, and IE 8 will display a page in the same way that IE 7 does. In my testing, I found that most pages worked fine with the standard (new) mode, and that most errors were minor cosmetic ones. Unfortunately, the Compatibility Mode toggle button may not be obvious to most users, because it's pretty small; a text label would have helped.
Though it probably won't convince many Firefox users to jump ship, Internet Explorer 8 Release Candidate 1 shows promise, and may be worth considering for people who have not yet solidified their browser loyalties. (Keep an eye out for our report on the final release of IE 8.)

Microsoft on Monday released a near-final "release candidate" version of Internet Explorer 8, the next version of its Web browser.
The software maker plans to say more on its Web site around noon, but, as noted by enthusiast site Neowin, the code is already available from Microsoft's download center.


With IE 8, Microsoft is hoping to regain some lost ground by adding features such as private browsing, improved security, and a new type of add-ons, called accelerators.
On the security front, Microsoft is adding a cross-site scripting filter, as well as protections against a type of attack known as clickjacking.
In an interview, IE General Manager Dean Hachamovitch said there will be little change between the release candidate and the final version, though he declined to say when the final version will be released.
"The ecosystem should expect the final candidate to behave like the release candidate," Hachamovitch said.
Internet Explorer 8 will work with Windows XP (Service Pack 2 or later) and Windows Vista. A version of IE 8 is also being built into Windows 7.
However, the IE code in Windows 7 is a pre-release candidate version.
"Windows 7 enables unique features and functionality in Internet Explorer 8 including Windows Touch and Jump Lists which require additional product tests to ensure we are providing the best Windows experience for our customers," the software maker said in a statement. "Microsoft will continue to update the version of Internet Explorer 8 running on Windows 7 as the development cycles of Windows 7 progress.
