100 Miles Per Gallon Car In Conception


NICK BUNKLEY

The race is on to develop a commercially viable car that can travel 100 miles on a gallon of gasoline.

The same group that awarded $10 million to a team that built the first private spacecraft to leave the earth’s atmosphere is expected to announce today the rules for its automotive competition.

The group, the X Prize Foundation, says that the automotive contest, expected to carry a prize of more than $10 million, could have a significant effect on the automobile industry by speeding up efforts to use alternative fuels and reduce consumption. The average fuel economy of vehicles sold in the United States has remained nearly stagnant — around 20 miles a gallon — for decades.

“The industry is stuck, and we think a prize is perfect to disrupt that dynamic,” said Mark Goodstein, executive director of the Automotive X Prize. “Failure is frowned upon in this industry, and that doesn’t make for big advances. It makes for incrementalism.”

Even before it began publicizing a draft of the rules for the competition, the foundation had fielded inquiries from more than 1,000 potential contestants and institutions willing to participate. Many major automakers have also expressed interest in monitoring the contest, including some that are considering competing themselves.

Ideally, Mr. Goodstein said, some of the top teams would see their designs purchased and used in some form by automakers.

A General Motors spokeswoman, Susan Garavaglia, said the company had not determined its level of participation in the contest but would pay close attention to it.

“G.M. is always looking for new innovative technology to improve fuel economy and performance and reduce emissions of our vehicles,” Ms. Garavaglia said. “The key is whether or not it can be provided to the customer in a way that’s affordable to them and in a way that we can make it in a high-volume application.”

Indeed, the organizers want to ensure that vehicles entered in the contest, which will compete in races in 2009 to determine the winner, are commercially viable. Entries must be production-ready, unlike many of the fantastical concept cars that are presented at auto shows. Each team must prepare a business plan for building at least 10,000 of the vehicles at a cost comparable to that of cars available now.

In fact, several cars have been built that could travel more than 100 miles on a gallon, but they were expensive and were used only for demonstration.

“Building a one-off that can go 100 miles per gallon, I think any of the automakers could do that,” said James A. Croce, chief executive of NextEnergy, a nonprofit organization in Detroit that promotes alternative energy. “It’s mass-producing them that’s the problem.”

But if the Automotive X Prize works as intended, that problem could be resolved much faster than the industry might on its own.

“This is not a question of curing cancer,” Mr. Goodstein said. “The technologies to build superefficient vehicles exist. It’s just a matter of convincing manufacturers to build them.”

Software Filters Spam And Junk Using Human Eyes

The news-aggregation site Topix has developed software for filtering out spam and other junk from its message forums. To filter in the good postings, however, the site has turned to human volunteers.

Topix LLC is soliciting editors to oversee the forums covering every U.S. town and city. One or more volunteers from each of 32,500 localities will be in charge of marking the best messages and news items and perhaps writing their own articles on community happenings.

The idea is to tap the power of citizen journalists - everyday Internet users who may write a quick message on a corner traffic accident or complain about delays in garbage collection. Some of that is happening in the forums now, but those posts get buried among the more mundane writeups.

That's where the volunteer editors will come in. After undergoing an application process and screening by Topix staff, editors will be able to handpick their favorite items and move them to a blog-like section. All the other posts will remain elsewhere on the site, should someone really want to sift through them.

"We have 35,000 posts a day," said Rich Skrenta, Topix' co-founder and chief executive. "Let's find the best of them here and let that person promote that to the news stream for the rest of us."

He acknowledged user-generated news "is not fact-checked (or) edited and tends to be raw, in the words of the people posting it, but it comes in great quantity and it's very current."

Software will still try to identify the most relevant news items for areas without a volunteer editor.

Topix began as an aggregation site for news stories and represents one of several efforts aimed at helping people assemble news items from a variety of sources online rather than rely on a single media outlet, as was the case with the printed newspaper or a TV network's evening news.

It currently collects news from 50,000 traditional news sites and blogs. Readers can browse through them by topic as well as by their city or ZIP code.

About a year ago, Topix began to allow visitors to post comments as well, and Skrenta said that feature has become a large traffic driver and has led to postings of original news - not just commentary of news reported elsewhere.

That led Topix to begin thinking about ways to highlight the best, he said.

Rival sites like Digg and Time Warner Inc.'s Netscape let readers vote on what they like best, and news items receiving the most votes rise to the top. But Skrenta said that approach works primarily for national sites - there aren't enough readers in most communities to make that approach worthwhile.

Topix is a Palo Alto, Calif.-based company 75 percent controlled by Gannett Co., McClatchy Co. and Tribune Co.

Press A Botton To Change The Colour Of Your Sunglasses

Sunglasses which change colour at the touch of a button could go on sale within a year.

A small switch on the frame will allow the user to turn the lenses red, green or blue.

The technology uses "smart" plastics that change colour when an electric current flows through them.

Power is supplied by a tiny watch battery.

Scientists at the University of Washington in Seattle have so far only produced a prototype pair of lab goggles which switch between transparent and light or dark blue.

They expect a full-scale version of the "chameleon" glasses to go on sale within one to two years.

The team's leader, Chunye Xu, said: "Through polymer chemistry, we've developed lenses that aren't like anything else on the market.

"This could be the fashion statement of the future."

There are also practical advantages to having a choice of colours.

Yellow lenses, for instance, are said to enhance contrasts and improve depth perception, while a rosy colour brightens low-light scenes.

If a protective coating is applied, the lenses could also block UV radiation as effectively as traditional sunglasses.

Microsoft Windows OS Patches Released Faster Than Usual

Microsoft has decided to rush out a fix for a flaw in its Windows operating system, saying that the problem has become too serious to ignore.

The flaw, which will be patched on Tuesday, was originally disclosed to Microsoft in December, but it was not publicly reported until Wednesday of last week. The bug lies in the way Windows processes .ani Animated Cursor files, which are used to create cartoon-like cursors in Windows.

Since the first attacks based on this flaw were reported, security experts say that more than 100 Web sites are now serving up malicious Web pages that take advantage of the bug, and a new worm , has begun spreading in China, according to by Symantec Corp.

On Saturday, hackers posted sample code that could be used to exploit the flaw, and shortly after that, Microsoft decided to rush out the emergency patch instead of waiting for its next regularly scheduled set of security updates, due April 10.

"Over this weekend attacks against this vulnerability have increased somewhat," Microsoft Program Manager Christopher Budd wrote Sunday on the company's Security Response Center blog. "Additionally, we are aware of public disclosure of proof-of-concept code. In light of these points, and based on customer feedback, we have been working around the clock to test this update and are currently planning to release the security update that addresses this issue on Tuesday."

Such early patches are not unprecedented. Microsoft released similar "out-of-cycle" fixes in January and September last year.

For those who cannot wait until Tuesday, two unofficial patches for the problem are now available: The first is from eEye Digital Security Inc., the second was released on Sunday by a volunteer group called the Zeroday Emergency Response Team.

Microsoft's patch has been in the works since security vendor Determina Inc. brought the flaw to Microsoft's attention late last year, Budd wrote. "We've been working on our investigation and a security update since then."

Google Increasing Gmail Storage To Infinity Plus One Soon

Google announced today that soon customers of their Gmail service will have their storage size increased to "infinity plus one." The announcement comes shortly after Yahoo's announcement that their Yahoo mail customers would be given unlimited storage.

Greg Tomkins, an engineer at Google, is credited with coming up with the "infinity plus one" idea. "I was out in the yard when my kids ran up to me yelling at each other. My son said to my daughter, 'I hate you to infinity.' She replied, 'I hate you to infinity plus one.' And right then I knew I had the solution to competing with unlimited storage," said Tomkins.

He continued saying that his son's idea about putting "dragons and Pokémon" on the Gmail pages didn't go over as well with management.

Tomkins also said that they would be using new RAID technologies which allow them to store copies of e-mail in parallel universes. This means that if their servers crash they will be able to recover your data from another universe where they haven't.

"Once your Yahoo e-mail box is full, you'll be able to transfer it to Gmail and add one more message," said Tomkins. "Those Yahoos will have a hard time beating that."

When contacted about the Google announcement, a Yahoo representative said, "We will be making an announcement shortly about our million-trillion-billion infinity storage," and added, "Neener, neener, neener."

Not to be left out of the storage bonanza, a Hotmail representative said that while they "can't offer unlimited storage, they can delete all your e-mail at random intervals in conjunction with their Live OneCare service, to make sure you never run out of space."
