The energy of activation can sometimes be a very significant energy cost and catalysts can reduce that. Wikipedia may not be the best source in the world, but what I read seems consistent with what they taught in school.
Thermodynamics are unaffected as there is still wasted energy in catalyzed reactions - just less of it. It is still far from a perfect reaction in which only enough energy is put into the system to allow for the disassociation of hydrogen from oxygen.
slight clarification on your use of catalyst. Catalysts are by definition unconsumed in the reaction and do not provide energy for the reaction - the reaction would need energy from an alternative source - solar, electric, other chemical reaction. In this model, it is understood there is an energy cost associated with it, and that this cost is likely more expensive than directly burning fuel in the car; however, this still seems the most plausible explanation.
well,
it is quite possible that the press release is a bit over dramatic and it is not an "only on water" style design
what if it is powered at home through an electric powered catalyst that works as so:
2H2O + energy --catalysed reaction--> 2H2 + O2
now the H2 is stored and in the car you go 2H2 + O2 --> 2H2O + energy
if they can find a good catalyst that brings the cost of the first reaction down, then this isn't such a poor deal after all. it in essence provides a way to store electrical energy using hydrogen, but to the laymen, it uses "water" as its fuel after being charged up.

recycled oh's? RECYCLED OH'S?! I knew you were lying about just ones and zeros! you had it all.... just ones and zeros my ass... you had recycled oh's! how I long for the old days where you could recycle oh's and no one would care. These days everything is a bunch of ones and zeros disguised as real options... These days a third option is as useless as a third candidate in the presidential election.
well, seeings how the '~' came after the '.', it is clear that you absolutely hate this guy and you said nothing in a sarcastic manner. This new scheme will work wonders~
When the EEE came out, Windows wasn't an option. Unfortunately I don't have the citation at hand and am feeling a bit lazy, but wasn't the great sales of the Linux version of the Eee the reason MS decided to make sure Windows worked? ASUS providing both options isn't a bad thing - I would say its great.
It isn't fear, it's love - of money and sales.
The thing is, there was a fear of MS. A fear of retribution for daring to sell a non MS machine. It was in there license. From the old Caldera case, one would see that it was difficult to sell a non MS product without paying MS anyways, or having the rugs pulled out from under you. There would not have been an Eee in the old days because it was not an MS approved product.
ASUS is not in the business of shooting itself in the foot. No they most definitely are not the EEE is a great machine and we already know that ASUS can not dare put Linux on there other machines.
of course these are desktop systems... Yes, this is a different market, but I don't think people (manufacturers) are as afraid of MS as they used to be.
by selectively modifying html pages, are the ISPs at risk of losing common carrier status and more importantly, is this any form of copyright violation? Are the owners of websites that have ads placed entitled to compensation?
if these assignments are to be graded and the grade on the assignment will go as part of the assessment of the student, then yes this is cheating. On the flip side, if the sole purpose of homework is to learn, and credit is given based on the completion of an assignment, then no this is not "cheating" as the purpose is exercise. If you didn't get the answer correct, it was not going to count against you, and if you go to a forum, then all you have done is speed up the process (you don't have to wait until lecture).
So if your homework is not a "take home open book quiz" then I can not see this as cheating. 10% of a grade can be huge depending on the mean test score and grading curve. Keep in mind I didhn't read the article (just skimmed it), so I don't know how it applies here.
as long as there is an underclass that does not have equal access to the public wealth of information. We may not have as many people with kwashiorkor in this nation, but it doesn't mean we don't have an underclass that would benefit from a public house of information. An underclass with respect to information is critical in a society where access to food is not a concern. Having a means to sidestep class barriers has been the single greatest strength of this nation. People at an economic disadvantage have been able to progress in society. Do we need a government funded body to equalize access to information? I think that as long as the government interferes in the free market to prevent the propogation of ideas and science by putting in place patents and copyrights, we do indeed need it.
2) no where in my post did I ever make a claim that something was bad. only that libraries are being hurt. This forum was about methods to improve libraries, so I used the methods of this private corporation as a guiding light. As a member of the "public" it is definitely in my best interest to see that my money is put to good use. This has nothing to do with communism. While you may wish to shift the debate to whether or not libraries should receive funding from the state, that is not where we started from. By your conclusions, everyone wishing to see improvements in the services there town provides would be a communist.
As another who has spent a considerable amount of time in a library, I do find that there is room for improvement. I don't think that they will be gone anytime soon, but I think that a large part of the problem has to do with financing. My university library (undergrad) was only a place for me to study. I NEVER USED IT TO DO RESEARCH. Furthermore, in medical school, the library served the exact same purpose. On the flip side, as a medical resident, I used the hospital library extensively. Why? I am not going to pay to get access to articles my library can get me. That is the only reason I used it. I was doing research and it required me to get access to things I couldn't otherwise pay for.
Growing up, I used the library to be able to freely read books.
I think this remains the fundamental and most important role of a library. Equalizing access to information that the public could not otherwise get to. Sure, as a professional, I can afford to pay for things, but it seems that costs are proportional. The specialized texts I want now are considerably more expensive than the texts I had wanted earlier.
As long as there is an underclass, the role of a library will remain important. Given trends in society, the underclass is growing and the divide between those with access to information will only further it. Granted most people with access to resources don't use it, but every now and then it will make a huge difference.
Furthermore, one has to consider the library in question. A community library serves a very different purpose than a university library. I think that a community library would be better off avoiding trying to provide large amounts of space towards computers. Should they have them? Yes, its important to provide a complete set of services for those who may not otherwise be able to have them.
What needs to be done to ensure the relevance of libraries? How about longer hours? With changing work schedules, knowing that the library will be open would be useful. I hate having to leave an hour after arrival because the place is going to close. How about an in library mirror of the Gutenberg free text collection to ensure availability despite loss of internet connectivity. Libraries have been known as warehouses of information; just because the data is digital, this should not change.
Printing services for this information. How about being able to select a text from the Gutenberg (or other) online collection and paying X dollars to have a copy printed and bound in some fashion for pickup. This can be both a revenue generating and role preserving improvement to a library.
A coffee shop. I think that Barnes n' Noble have done more to "hurt" libraries than any other place. They're open longer and I can drink some coffee.... Its a huge improvement.
Club meetings - chess, reading - local competitions for the kids. There are many services that can be provided through a library that many libraries have already adopted.
My main request would be that they mirror important literary texts locally. Given the questionable and temporary quality of electronic media, its important to have as many copies distributed as widely as possible.
done ranting... need to find another task to avoid reading.
well, that's only true if you consider their successes. I think people are thinking of broadbased standard wars. of the ones you speak of, a walkman is a new style of device not a format/media standard. Hi8 was never complete media dominance in its class. No arguments with 3.5" discs, but how funny would my comment be if I mentioned it? There is no arguing with Sony's success (playstation versus pretty much anything else in its generation), but can we please refrain from mentioning strengths of international conglomerates? Slashdot requires that you route for David. Goliath is the enemy.
Video games develop a set of skills just as reading a literary work improves comprehension. Problem solving skills are often best learned by being tasks to complete. Video games if properly utilized can be used to develop problem solving skills along with motor skills. The appeal of educational video games (which were already around when I was in elementary school) may wear off, but I highly doubt they will disappear. Just as there are sports that some people don't enjoy during PE, there will be games given in school that some kids won't like.
The real question is whether people will be tested in there game playing skills. Are people expecting a rise of gaming to the point that people will expect competency at it? Will it be considered appropriate that a fifth grader can properly solve certain tasks presented in a virtual environment that has been deemed appropriate for them?
The thing is, people who play RPGs do learn certain skill sets whether they intended it or not. People playing a FPS develop certain skills. Finding a way to translate these skills to the real world (robotic surgery or engineering) is a task for the next generation of teachers. Using examples from pop culture has always been a teaching modality - it depends on the quality and capabilities of the educator to show the relationship between things done in the classroom and how they can help in daily life.
I am sure someone much smarter than me will one day show the great wisdom gained by being a WOW farmer (couldn't come up with a better example, I don't play video games much - I spent my childhood writing and hacking cheesy games instead of playing them - but that is because I suck at them).
Wasn't Sony on the wrong side of all these battles? What gives? Sony may actually win a standards war? What's next, other companies will use memory stick?
from what I have heard, it has to do with reclaiming used memory. if you have a a bunch of small allocations between larger page allocations, what will happen is that when memory is freed (to prevent a leak), you end up with small wholes in the memory that are not large enough for another page allocation or to return the block of memory back to the system as unused - ie only 1k of a 4k block is being used. This leads to large amounts of RAM usage. I have heard that opening a new window (not a tab) and closing old windows will occasionally alleviate part of the problem
if MS wanted to roll out an "evil" patch - they would merely embed it as part of a much needed security update. Don't include the evil patch and your system will remain compromised. Works a lot better than trying to kill this project. but I do agree with the control issue, just don't think that this takes away as much control as it lets on (except bypassing WGA?)
you know, I was rereading my post and thought I was doing well until a few sentences in. Normally, I wouldn't respond to a post like yours, but you see that is an assumption. I haven't had a grammar nazi attack me thus far... damn, you made me go Godwin on you!... If I am to be attacked on my misuse of words, then I hope that the person doing it would at least try to maintain proper grammar in their criticism. You see, English isn't my first language; however, I assure you that I know better than to use a conjunction to begin a sentence - though I may do so myself, not claiming to be a formal writer. You may rebut this by saying that the post is not a formal writing, but misuse of the proper {"there", "they're", "their"} may lead to confusion; however, I contest that by saying that the flow of the sentence would correct any misconception, and it is the flaws of the English language that pose the problem. Also, I would like to suggest that you include a subject and verb in your sentences.
A solution that may appease both of use would be a fundamental change to the English language that leads to much of the confusion in it's written form. For one, the use of the letter 'c' is entirely unessassary as a 'k' or 's' kan be used as eqwivalent substatutes. U may have also notised my use of "kw" instead of the ugly "qu". This is bekuz of my opposition to the letter 'q' beeng used in the langwidg. so, plees help me eliminate the c and q from the language and I will then make sure I double read every post for the korrekt use of {"there", "they're", "their"}. Until that time, I will continue to be human and go more for the content of the post than ensuring I comply with the silliness of the language. I know there are many rooms for misinterpretation, but I already try to avoid those.
well, the problem is about how you define who MS's client base is... it certainly is not the consumers who end up buying their machines - those are just annoyances that they must deal with. Their clientbase is system builders and more recently content developers. They will cater to those making the content that moves the boxes. They are essentially no different than ASUS or any other component provider (except for their monopoly and willingness to abuse it). These companies do things according to what there clients (the computer builders) want so long as it fits there goals. The fact that these eventually move on is not there problems.
if people want MS to lose there monopoly, pressure needs to be put on companies like Dell and HP to push pressure upstream for better hardware support in alternative operating systems. Right now, the lockin ability that MS provides these people is important (i.e. Dell software that ships with there systems isn't so portable thanks to measures taken by MS).
This is also why they can push adware on one hand while simultaneously sell software that takes other peoples adware off your system.

Sure they can,

How is Darl?

didn't sun buy star office and give us the OPEN SOURCE - openoffice.org?
given the size and nature of this move, I don't begrudge sun anything in its commitment to open source.

http://www.ucsusa.org/ssi/archive/ozone-climate-connection.html seems like a decent read on this. I don't think the GP was too far off base. perhaps not the most significant thing, but still the GP was correct.
well, you made two points, so here is my response
1) about the underclass.
as long as there is an underclass that does not have equal access to the public wealth of information. We may not have as many people with kwashiorkor in this nation, but it doesn't mean we don't have an underclass that would benefit from a public house of information.
