Well, I posted this in the other PB G5 thread, but strangely no one seemed to care. Doesn't anyone read the AI mainpage anymore?
AI predicts Powerbook G5s with liquid cooling system. 17" model could arrive by next summer.
"AppleInsider has received slightly more detailed information -- albeit via unconfirmed reports -- on the PowerBook G5.
One of the major obstacles facing PowerBook engineers is the intense heat emitted by the PowerPC G5 processor. (While a single processor Power Mac G4 (QuickSilver) draws 338 watts, a single processor Power Mac G5 requires 450 watts.) To help combat the problem, sources say the company is experimenting with liquid cooling systems in early prototypes of the portables.
Liquid cooling essentially functions as a radiator for the CPU inside of a computer. Just like a typical radiator, a liquid cooling system circulates liquid through small pipes in a heat sink attached to the processor module. As the liquid passes through the heat sink, heat from the hot processor is transfered to the cooler liquid. The warmed liquid is then cycled to a radiator on the side or rear of the casing where it is released into the ambient air outside of the unit. The cooled liquid then travels back through the system to the CPU to continue the process.
IBM, manufacturer of the PowerPC G5, has been using their own liquid cooling system in ThinkPad laptops since the late 90's. Referred to as the "thermal hinge," the design made its way into ThinkPad prototypes in 1999. However, with wattage of CPUs on the rise, the company was already designing a more effective, cost efficient, and easier to manufacture solution two years later. Last year, Hitatchi unveiled its "FLORA 270W Silent Models" which were equipped with silent water cooling systems consisting of a water storage tank.
In January, a researcher at Sandia National Laboratories announced that he had created technology to disperse the heat generated within laptop computers more efficiently than the current cooling systems. The new process uses heat from the CPU to convert methanol into a vapor with the aid of a heat pipe "wick" created out of finely etched lines. The vapor then releases the heat it is carrying in a specified area, where it turns back to liquid and returns to collect more heat.
At the time, the technology was being licensed to an upstart company, but no further information was made available.
While Jobs says Apple has hopes of producing a G5 PowerBook by the end of next year, sources expect -- with the aid of such a cooling system -- the company to be able to deploy a 17-inch PowerBook G5 by next summer. Due to its extra size, the 17-inch model currently provides the most leeway for implementing a liquid cooling system. However, a liquid cooling system is said to increase the manufacturing cost of each unit.
Apple is also said to be experimenting with newer lithium ion batteries that will be required to sustain sufficient battery-life on a portable G5 unit."
I disagree. Apple has done real well with the G5. IBM released the 970 chip out to the public, and then 2 -3 months later, the G5 Tower was released. In all honesty, I think Apple will continue with this trend with the Powerbook.
Theorize as you might about what Apple and IBM are capable of doing, I think it's clear that the comments that we've heard first from Greg Jozwiak, and now from Steve Jobs, that Apple is trying to prepare us for a long wait for G5 PowerBooks.
Perhaps you have an very optimistic view that "end of next year" means anything after June 30, or you think these comments are deliberate misdirection so that Apple can spring an early G5 surprise on us and sell more of the current product in the meantime.
Me, I'm inclined to take what I hear at face value in this case. While Apple certainly works hard to keep its secrets, and while they've overhyped in the past now and then ("Way beyond the rumor sites!"), I don't recall Apple ever being deliberately deceptive about how late a product would arrive.

I agree that Apple has never deliberatily been deceptive. I think that with the information that they both knew at the time, they were quite accurate. Actually, this was more commenting on IBM's stellar performance as of recent. They have said that things are progressing much faster than they anticipated with the 970+.
Also, I was commenting about how Apple as of recent has wanted to get its products out into the public, instead of waiting for an expo, or something of that kind.
Honestly, I don't think we will see them until August of 2004. However, I do wonder if that timetable might be pushed forward with IBM's recent advances, to more of a April - May timeframe.
You know what? Just seeing how things go in general (the time between updates and Apple's reputation for letting LOTS of time go by), I have to say that I'll be shocked - absolutely SHOCKED - to see any sort of G5-based PowerBook before next summer.
I am officially going on record in saying that I believe the 2004 summer Expo (whatever/whenever/wherever the hell it is) will be the absolute earliest we'll seen one.
Frisco in January? Sorry, I just don't see it. I can't imagine...this past update took SO long. I can't see these PowerBooks released on Tuesday just hanging around for 4 months.

I see MWSF '04 coming and going (and everyone here bitching when no G5 PB appears) and on into the spring. I figure around March or April, all the usual suspects will start their "sources confirmed that..." and "we have received word that the..." stuff, which will basically volley back and forth for 3-7 months, enjoying varying degrees of wrongness.
We'll get built up (WWDC?) then let down (bastards!). Then when we're about to choke each other and least expect it, Jobs will roll them out with a splashy debut and the joint will go nuts. And you won't be able to get one for less than $2199.
And the usual round of pissing and moaning will begin THE DAY OF, lamenting the lack of this, the exclusion of that, the price of this, the weight of that, etc.
Think I'm wrong? Look me up next summer and test me...
I really hope that they are working on them right now. IBM or Moto will have to come out with another processor, because @ 2.0Ghz, the thing is too hot. But I'm sure by then they will have the process perfected for cooler speeds, less wattage.

cooler wattage, heh heh, alllllright.
-walloo.
