Well, you can scratch Antarctica and Siberia as places you can't use this notebook, if the liquid coolant freezes in very low external temperatures.

With the amount of heat the P4 generates, you might be able to cook pizza, replace home central heating, ...
Water-cooled? That's boring.
Now what I want is an Ice-Cream-Cooled Laptop. Like an electronic Klondike bar. Mmmm...

Someday far in the future, I'll be up very late in my office, listening to the silence, and thinking "Man it sure was alot less lonely when we had those fans going."
My handle breaks slashcode, what does your handle do?
Kind of like Honda shipping riced up Civics by default, it's pretty funny that the industry is following the overclockers. To take a look at the roots of water cooling, check out the definitive hobbyist on the subject, complete with alternate designs, plans, technical faq - the works.
Personally, I'll buy it when it's packaged and done for me, and not until then.

If a p4 needs water cooling, something is fscked up.
Imageine the future of "changing the water" every so often in your laptop. Thanks, but no thanks.
According to the specs, the unit will produce 0.3 oz of 140 degree-F. water per minute. Therefore, it should only take 15 minutes to brew one Standard 5 Oz. Cup of coffee. Now, if they can only get the CD-ROM drive to double as a cupholder....
point taken. It was not a dig at the P4 directly, more at how hot those processors can get.
You can already buy water cooling kits for your PC. (This company is accepting backorders.)
Like a liquid that doesn't conduct electricity, isn't caustic, and isn't extremely sticky when dried? It would seem to me that would make for easier repairs in the future and make for a safer investment in an unproven application of cooling technology.
People expect reliability out of their performance laptops, afterall.
With the power consumption on a P4 you wont even be able to keep the thing alive(on battery) long enough to over heat the processor.
I know I'm going to hell, I'm just trying to get good seats.
If you want a water cooling system but don't have a notebook, http://www.agaweb.com/coolcpu/ is a good place to start. I tried it out once and overclocked my system by over 50%.
Water has a much higher calorific capacity than air. I believe it's around 4.19J/g*Celsius which is very high.
It is the logical choice for cooling, being less noisy, parts have to move slower, etc etc... But why does the article say this is for garage hobbyists? Water cooling has been around for a while and at least 5 relatively large cies offer it. Tomshardware and Anandtech have had quite a few reviews of the different brands.
Another plus is you can plug everything on the same circuit, Northbridge, CPU, GPU, hell, even the power supply. All you have to do is increase the pipe size by a relatively small factor.
The temperature is maintained around ambient too, so the cooling is MUCH more efficient than air.
The next step is nanocooling. There was an article in Nature a way back about nanofans (more like oscillating piezoelectric thingys), that dissipate heat at an astounding rate (although I don't recall how exactly since they throw it at the air which doesn't have such a good calorific capacity...). Anyways, the point is that this isn't really revolutionary because it has been used in home computers (by more than garage hobbyists) for at least 3 years. And before that there was Kryotech...

Look if I have to lug around a water tank and pump then what's the use of having a laptop.

Chalk it up to a publicity stunt. Laptops already are starved for power. You start adding a water pump to the mix, and you drop your usable time by at least a 1/2 hour I estimate. In any event, if your processing so much with a laptop that you need a water cooler, you should be on a desktop.
I does not add up.
As cool as it sounds, someone else thought of it already :)

As one who has done considerable research into watercooled stuff, the cooling gains are pretty good as compared to air cooling. This is multilied by the fact that the active cooling system on a notebook is limited to a tiny 60MM fan, and a heatsink that is about a half inch high. If you can keep the system closed, it won't be too bad, however this will add considerable weight to the unit, taking into account the resevoir, pump, waterblock, stuff like that.
The source of new water can be the output of your methanol fuel-cell batteries :)

Dell has cooled its laptops via water for at least a year now. Take apart any Latitude or Inspiron over 800MHZ and look at the small copper pipes that sit in front of the cooling fan. Those pipes circulate water over the CPU, helping to cool it.
No, really, I didn't wet my pants!! My laptop leaked!

Water cooled laptops are nothing new at all. Check out these water cooling laptop articles, produced from a quick google search:
Toshiba
IBM
I know there are others, but I can't seem to find them at the moment. It's certainly my underestanding that there have been water cooled laptops in production for quite a while.
What happens if you add water cooling to your cray, and you start a level 1 hurricane over your processor?
Isn't this really just more evidence that a P4 is inappropriate for laptops? Intel is making a good attempt at targeting a specific market (P4 is "primarily" a server chip), but their insistence on cramming every processor into a small box just for shits and giggles is silly.
We could use the natural thermal properties of a closed system to circulate the water, by having it rise to exchangers in the screen-backing area...
We could then start adding turbines to reclaim some of the energy lost as heat from the unit, and use that to help prolong the time between charges on the unit! Just think! The more hard number crunching you do, the hotter the processor gets, and the longer your laptop runs! It'd be a reason for EVERYONE to run seti@home!
IBM had PL/1, with syntax worse than JOSS,
And everywhere the language went, it was a total loss...

First of all, I'm not sure your laptop will last long operating at freezing temperatures anyway. Plus, it would take longer for the wanter coolant to freeze (even without an addative) since the computer produces heat. Why was this insightful? Funny, maybe.

I thought that for atleast the last 10 years that supercomputers (well, crays atleast) have been using flurinert, and I don't think that they ever used water for the job.
honestly, isnt a P4 in a notebook a complete and total waste? The main performance bottleneck in a notebook anymore is the harddrive, not the CPU. The whole idea of a laptop is to be able take it to various places and be able to run it for a few hours on the battery. With the kind of power the P4 sucks down, you can kiss that goodbye. Add in fans to cool down the processor and/or water, and more of your battery goes bye bye. You'd need DDR to get the most out of the P4 as well, sdram + P4 is horribly slow and Rambus generates huge amounts of heat, which we all know is a no no in a notebook. I'm sorry Intel, but not everyone wants or needs a Marketing Processor (which is what the P4 really is, marketing over engineering) in a notebook. Give me a cool running low power Mobile P3 any day of the week.

Maybe I'm being silly, but is this really neccessary? I'm sure it will sell. I work in Government, particularly law enforcement, and the purchasing decisions are made totally backwards. Recently, all of the agents (cops) in our department got new laptops. It was considered important that they be able to transport these things so that they can be more flexible or dynamic or something... Anyway, the guy in charge of ordering bought the Dell "desktop replacement" laptop, which weighs about 8 pounds! The result? We have a bunch of overpriced desktops with LCD displays and laptop keyboards. The agents never take them ANYWHERE.
To get back on topic, I can see how this is going to be a "It's more expensive, so it must be better," or, a, "Finally, I can get the computing power that I need in a laptop!" I've had a Pentium III 850 for almost a year now and I just can't see how that isn't going to be sufficient processing power to drive my applications for a long time. Up until a few weeks ago I was using a PII 300 at work, and it was great with Windows 2000 and office XP.
The gist of my comment: In 90% (or more) of the instances customers who buy these machines will not need the processing power that is provided by the advanced cooling. My problem is when it's public sector buyers that are misinformed and willing to spend public dollars on gimmicky stuff.
Wait, never mind, maybe you do need that Pentium 4 to do email...sorry!

I already have this 8 months a year. I live in Seattle.
Personally, I'd have engineered the water tank to the bottom of the unit or as another drive bay. Gravity would force the water from a broken unit outside the laptop.
The change in pressure won't effect the volume of the coolant (assuming it is water.) Only a gas coolant would be effected. This does however effect the boots used by the Canadian military. Their winder boots have a pocket of air to help insulate them. They have a little air valve on their side that needs to be opened so that the boots don't explode during air transport.
By the way, if anyone ever needs some very warm, durable boots - check out an army surplus store. The only commercial boots that even come close are in the $300 range and aren't as durable. The military has some damn nice equipment...
Watercooling requires a way to move that water, ie, a pump. Moving parts that require power, and the problem is that you still have to get x watts of heat out of the water at the other end. I think the current use of a heat pipe is much better than watercooling. The only "movement" is the phase change powered by the heat itself, and so there is less chance of failure.
--------
It's OK to be social, just don't tell anyone about it.
With current tech, we could create a 486 based word processing machine, thinner, cheaper, lighter, and with a week's worth of power, rather than just a few hours.
Why they insist on forcing desktop replacements on the market is beyond me. (Actually, it isn't beyond me, it's all about keeping those profit margins high.)
As a writer, dealing with these noisy, overheating, overpriced, heavy machines is distasteful. As a programmer, I'm gonna use my laptop as a terminal, not a server, so all those extra CPU cycles are wasted.
I wonder how long the battery will last... like, 30 minutes?
The Powerbook G4 has 3 liquid cooling channels in the latest models. If I recall, the earlier Powerbook G4s had only one liquid cooling channel.
My dad has a pair of surplus US airforce boots with the same design - air surround and a little pressure relief valve. Quite Neat.

(I figure if they can make a P4 run four hours, the P1 should be good for at least four times longer!)

I can't see any downsides. More computrons, faster brewing. Everyone's happy.
As I was reading the article, I noticed an interesting sentence:
Although the water-cooling system is more efficient and less noisy, the bottlenecks to commercialization have been that the water-based solution tends to degrade and evaporate during operation.
Maybe it is just me, but the idea of fueling my laptop with water instead of electricity sounds great! I can't wait until I can say "Hold on a sec... I have to refill my CPU with this bottle of Evian..."
Now I'll have to worry about my computer overheating when I forget to check the water.

Here's something helpful for everybody:
(Oh those watercooled notebooks are somethng else)
How to lie 101:
First off, make sure you're white... it makes it much easier to justify why you're such a cracker.
Second, it takes lots of practice to make a really solid lie, so if you want a good lie, you'll need to work on your excuses... which kind of defeats the purpose so f%4k it.
Third be a complete dick about everything... never justify lying, it takes too much energy.
If you ever wake up and think to yourself that life is perfect, it's possibly not for somebody else, so watch your ass... which of course is impossible if you want to lie.
If you wake up with a perfect body, lots of money, a nice car, a family, a beautiful wife/husband, an easy job that makes lots of money, you might be in for a rude awakening. Why? Once again you're living a lie. Don't ask me how it happens... all I know is that it does.
Fifth, always have a good spellchecker... if you don't you can end up looking like an idiot. This can really hurt.
Oh, never tell the truth to the opposite sex no matter how much since it makes to do or even if they already know it. Why? The f$#king truth hurts. Then you'll be straight out of a girlfriend/boyfriend... not to mention you'll have to settle with a girl who knows the truth. What a bitch. Literally. This means for all you guys you can't tell them you're dating them for their looks and for all you women you're dating them for their money.
Oh... putting up a "front" is "mas importante"... that's Spanish for important. So I've been told anyway.
Oh... get really good at lying to yourself. It's the best... Never tell yourself the truth because the sh%t hurts...
For you really good liars out there, everything, and I mean everything about the truth hurts to the point of being ridiculous. Why? Because just like you liars, "truth tellers" are just like you except they have been put in a position that they are forced to "put out", so everything is tweaked for them to get the most out of it. So if you really want to get the most out of lying to someone, you must, and I repeat must, be a complete dick. Now the BEST liars do this with out consciously knowing it... thus getting more "bang for the buck" out of their lies. This is because truly could give a f%$k about anyone else. It's the best! I have to say, try it for yourself and see what I mean... it's great!
Oh... and if you get caught... Being naturally stupid really helps the situation. Why? You forget faster than average and thus get back to your main objective that much faster. It also really helps not to have a conscience also in this situation. So if you can see about finding a doctor stupid enough to get that part of your brain removed as soon as possible. If not, it could take years of training or tons and tons of time around "truth tellers" to get it finally right. Oh... you must also sometimes pretend you're a truth teller also in this situation . It's good to have "studied" the enemy. And surprisingly, there are a lot of them. Also, if you are not stupid, but your opponent thinks you are, use that, it works great! I hope I'm not boring you more intelligent people with this rudimentary knowledge. See how I just played to your ego? It works perfectly with those who, deep down, know they are God, and everybody else is simply crazy. Wow!
Oh... go to Church or Temple or whatever it is you're supposed to do... you'll hit "pay-dirt" with tons of idiots practicing stuff like "self-sacrifice". If you find one of those guys, you're SFL baby!
Being around massive quantities of women always helps your chances as well. Thet naturally excel as liars. The evidence is in asking them... they'll say no! Don't worry if you did not catch on to the last part...
Being in numbers also helps... sometimes you'll be in the midst of a liar So good that he can say a lie that will cover you at the same time... now that's a bonus!!! Just pretend you're with them... you might not want to tell them that you've said this though or they might call you out of it... after all, they're lying also.
Oh... make sure you have plenty of money... for where your lies fail, your money will smooth things over... it's really a necessity.
Also, competition in lying... there is tons once people figure out the need to lie. If you find yourself in the midst of a better liar, sometimes it can be tough to keep your spirits up... but do! You see, you can learn from their lies, and then get better at them yourself! Sometimes you can get the "hang" out of a particular lie without taking tons and tons of time to learn it (like that person might have), so you in essence, steal their lies! It's really great!
Getting back to that Church thing... If you go to Church you can learn about miracles and thus blame all your really bad lies on the fact that they were part of a bigger plan. It works perfectly. At least it works good for me. Remember, "Everything happens for a reason!" I can't tell you how good this one works! First off for those stupid enough to believe it, they fall for it almost every time as long as you don't use it back to back, and for those who know better, they're so pissed at how you judged their intellect, they'll be stunned! (but only for a few seconds, so be quick to come up with something to take their mind off it and distract them from the fact your playing them)
Make sure you have plenty of excuses. The best excuses look self-evident. For example, walk into work with a fake broke leg. You get the point.
Situational Lying: This is where it gets advanced. Any given situation can turn into a "lie detector test". Make sure you can either bully your way out if caught, or you can put your lie out quick enough as the truth. Being naturally paranoid helps this situation as well. Remember, people conspire behind your back so always have a good lie ready. Furthermore, the more conspiracies you're in on, the better. They show what situations work best, given the strategy. If you suspect yourself the victim of a conspiracy, this is when your true lying skills really come into play the most. If you can't find your way out quickly, it's best to become part of your own conspiracy. This will confuse the stupider of your enemies and will give you time to get out scot-free. Remember, the deeper your lie the higher the probability you'll get caught. So start off small. (Just like weight training)
If you get caught: Keep your enemy happy. Distraction is key... especially if they have drugs to tell you the truth or a lie detector. It's survival of the best liar. Women once again have the best advantage here. They use sex as... and get this: weapon, I dare say AND a means to get out. Almost unbeatable, really. This is the very driver of most men's existence and so it works almost %100 percent of the time! Joy. This is proven by the small amount of women that make it into prison and very few are killed. Smart men know to use a woman as a means of defense, hence the phrase: "Take my wife, please!" If a woman catches you in a lie, tell them you learned it from them and then proceed to get very juvenile or senile. Then tell them they should be proud to know such a liar. (Remember, if you're a woman you should work on your looks more than your lie as it will help you facilitate any of the fore mentioned situations... you might find yourself at the command of your victim!!!)
Being physically fit can also help your lying in that it will keep you from getting caught. Also, people tend to be less harsh on these types of liars since they have a weapon.
Extremely advanced lying: Once again, I can't tell you how much material I have given you is true. After all, I myself am a liar and when in full practice I'm very deadly if I do say so myself. It is true possibly that my lying behavior has become too much of a "component" of my personality in that it affects everything I do, including this paper. Furthermore, a lot my lies are still "in the works", so some of this advice might work out your particular situation.... All I can say is if it's true, that's too bad for you. Also, remember the expiration date on the milk carton... you have to change up your lies in order to keep your lying a tool for survival.
Some of the consequences of lying: First and foremost is Hell. A mere possibility, but watch your back! Second, mental behavior facilities... believe you me, you don't want to end up there. So, if you have already started lying, watch your back because the people who work in these places tend to be liars themselves and love to play with their victim's minds and anything else that comes to light. What's worse is you become a victim of some stupid experiment. In this case you should behave as if you're the victim of a conspiracy, (but don't tell anyone). Experiments tend to behave exactly the same as conspiracies. Remember, once you've started lying, there's really no going back. This is proven once you tell somebody that you've lied to them. They will not treat you as an equal anymore and you will have lost all respect for you. (and in most cases, they'll let you know it... if they are smart anyway.) You can lose your job, your family, your life, and your money. Your entire life will be watched and analyzed, thus becoming part of some crazy freak show that people can look at, poke fun at, and feel generally better about themselves due to your getting caught. Wow! Suddenly you've made other people friends and have them come together as a click all due to your stupidity! And believe you me, clicks can hurt if you're not "in".
Some benefits of lying: Monetary growth. There's a lot of money to be made of being the best liar. Just look at the movie industry! Millions of dollars on what people have made up and at best a bunch of half-truths to keep you happy. Remember "fake it to you make it!" Women! Women love a good liar. (Actually, women fall in love with a good liar only to be disappointed... I can't tell you how many times I've been personally a disappointment.) Being a good liar is a sign of true stability in your life. I can't tell you how may women I've got simply by being a good liar! A happy outlook on life. Once your convinced you've made a lie big enough. To fool everybody you need to, you can relax and laugh at all the suckers you've made!
Remember, right or wrong, people love to abuse other people. They'll even accuse you of abusing so they can further abuse you! It can get confusing so use every spare moment to "keep score". This is justification for lying enough! People will hit you for cursing! Does that help their outlook from your perspective? No! I've seen people really get an ass-kick from this situation. Remember, win people over with your money, looks and other seemingly quality aspects. When in a bad situation, always have dirt on somebody. This goes out of the bounds of being just a liar, but it's a great defense, so it would be selfish not to share it with you. It's a great defense. Just talk about their problems and you've got instant defense! This defense works on those smart enough to know what you're talking about, however, remember: Size up your opponent! Otherwise, you'll end up looking stupid. This works best with a lot of people around... make a crack on them that's so funny that it causes everybody to laugh uncontrollably and you've got instant success! Once again, this goes out of the bounds of merely lying, but is an excellent defense that not only wins friends with your humor, but hurts your enemy... all at the same time! Man! Now that's a bonus!

He's right, mod him up to get the facts out.
Have you considered a 14" 600MHz 6lb iBook for your needs?
Word, Office, bash, sips at the battery, and comes with a fairly hefty 55W battery too. It runs, what, at a rated 6hours on a single battery? I suspect it runs lower, of course, but still, 4.5 hours isn't horrible.
GPL Deconstructed
Perhaps this could be used with a steam turbine to recycle some energy. It would almost be like turning your mobile into a perpetum mobile.
It'll work until the magic liquid leaks?
Antti S. Brax - Old school - http://www.iki.fi/asb/
...it consumes way too much power. Come on, this is a laptop, it is supposed to run of a battery.
i think it is *hilarious* that some processors (ahem) need water-cooling. (why is it that i always think of Rube Goldberg when it comes to an Intel, et al, chip? DOH! ) they are, by defintion, inefficient... watt-suckers that could heat your home. PPC chips, on the other hand, run nice and cool in comparison even when overclocked a tad. and they suck much fewer watts. but i digress... LOL.
If I want a water heater I buy a coffe machine - not a notebook.
-- Contradictions only exist in thought - not in reality.
The Armada series of laptops had a water cooled processor.
... the only new thing about this may be in the details. The idea is old.
The basic structure was a copper pipe arragement with a reservoir over the cpu. As the water heated up it set up a convection current to the end of the pipe (think thermometer action) moving the warm water away from the processor and cool water back to the cpu. If the system began to get too hot even then the pipe end was aided in the heat dissipation by having been run in front of a general purpose cooling fan (that ran only if necessary).
All in all
Heat pipes are an old idea - they were used in the Apollo program. IBM's key addition to the technology is developing a hinge that efficiently transfers heat between the laptop's body (the heat source) and the display (the heat radiator). There isn't much info in the article referenced in the original post to figure out just what Hitachi thinks is original.
So... they don't make any extra profit (probably less for an identical retail price), there's no extended battery life (so how is this "more efficient"?), and the only benefit is that it (apparently) lives longer than an air cooled system, a fairly intangible benefit even for a corporate purchaser, given that by the time the air cooling system is likekly to give out, the laptop will have moved so far down the corporate food chain that it will probably have long since been "recycled" by a sticky fingered employee.
Some problems with this.
Technology for technology's sake? This is a demo unit, and is smells to me like some R&D czar trying to garner some media interest in a dying project. It's nice technology, but it seems largely pointless.
If you were blocking sigs, you wouldn't have to read this.
Two obvious ones:
1) And you thought MEMORY leaks killed programs...
and
2) Going into that super important customer meeting after the water coolant just let go leaving a huge wet spot on the front of your pants: "No, really, it was my laptop!"
--- I wish I could hear the soundtrack to my life. That way I'd know when to duck.
Isn't water relatively dense? I believe it weighs about 33 pounds per cubic foot if I'm not mistaken. Even a cupful would significantly add to the weight of a portable I would think.
Don't think that a small group of dedicated individuals can't change the world. It's the only thing that ever has.
Is there such a thing as a corporate user? Do corporations still buy anything when the economy is being driven by consumers?
Dell Latitude laptops have had basically a radiator for the past 2 years or so. It is completely sealed of so most people don't even know there is water in it. It was added the same year they added the big rubber bump on the bottom as a shock absorber.
I live in Norway, and for about 4 months or so we have temperatures below freezing. What happends if i carry my laptop home one of thies days. Will the pipes burst when the water freez?? what about using spirits instead of water? does spirits conduct heat as good as water? We already use a mixture of spirits and water to cool our cars in the winter.
Your post, corrected: "Dull attitude slapslops have had basically a radiator for the past 2 years or so. They are completely worthless sacks of shit that barely work so most people don't even know there is a CPU in it that is so damned inefficient, such a watt-hog, that it requires liquid-cooling."
And I basically had a cow when I read your post. Everyone I know that has bought a Dull slapslop has hated it. Dull should only go bankrupt. NOW.
I see a new franchise of "Super Soaker Laptops" being created.
You're claiming that overclockers invented water-cooled computers? What about, for example, the Cray 1? And there's almost certainly earlier examples. This is really old industry tech, not some crazy idea the hotrodder kids dreamed up.
Surely it would be a good ideato develop
this idea so that the heat lost by the processor
could be regenerated back into electricity.
This would beparticularly useful in laptops
in conserving as much battery power as
possible.
Gez every 2nd laptop currently being made has a heatpipe - its no big deal
"Heatpipes" are nothing new.
Although heatpipes are mainly utilised where things are cramped arround the heatsource, to move the heat to another spot where there's more room for a heatsink (hence its popularity in laptops, where they move the heat from the CPU to behind the screen, where there's room for a wide albit flat heatsink), there are a couple of Socket 7/370/A heatsinks that utilise the heatpipe effect. The "Zen Radiator", which uses the heatpipe as the core of a radiator like arrangement; & the "Coolermaster HHC-001 Heatpipe Copper Cooler", which has long (as in high) fins & uses heatpipes to help conduct heat to the top of the fins.
All this article shows is that PC World employs a laptop reviewer who doesn't know what he's talking about in regards to laptops.
Really if a tech mag is going to have someone write a blurb about laptop cooling they should employ someone who actually knows something about laptop cooling.
For years and years (and years and years) Denon has used refrigerants (freon and such, unfortunately...) running in a tube directly through the cooling fins of the home amps they produce.
Why not on PCs?

Instead of duct-taping a horribly designed chip in with water-cooling and refridgeration units, why not just use a more efficient chip architecture? It's not like they aren't available. And the market's large enough to support more.
Lies about crimes
And I thought it was bad when the water pump died on my car!

Water cooled notebooks.
I recently heard a presentation which indicated just how difficult the situation is getting with respect to power density. IIRC, in terms of W/cm, todays chips are surpassing the output of hotplates, moving towards the realm of nuclear reactors.
I'd heard the switch from bi-polar to CMOS in the 1990s helped to avert a similar imminent meltdown.
At these extremes, there have to be some research efforts into finding some way out of this mess.
But maybe there's little need for laptop computers to have a faster CPU. What are you going to do with it, type your email faster? Once you can show videos in Powerpoint, why is there any more need for speed in these things?
"Provided by the management for your protection."
If only notebooks would allow you to easily underclock, then you run at lower power and not bake your lap or boil water.
What is dissolved in the water?
