We'll see it at an Apple hosted special event...within 4 months. I'm just pretty confident that a company that had hadwriting recognition on a PDA in 1993 can also muster the engineering required to dissipate heat inside a Powerbook....The Cube, the flat iMac, the iPod mini....this is what these freaking people do...if Apple gets a challenge they find ways to solve it, being the brilliant people they are.

I think trying to adjust cooling technologies to the heat of a real desktop processor, just to make such a processor usable in a notebook, is the wrong approach. Assume you achieve that point, what is your upgrade strategy after that? How do you manage the even hotter processor at higher frequencies?
Apple needs now a new family of 64-bit processors, specially designed for the Powerbooks. IBM tried to say something back in the introduction of the G5 (embedded mutli giga-hertz SIMD enhanced 64-bit PPC processors), but since then we heard really nothing on this. Nothing. This tells something to me.
My housemate was in the apple design centre and saw graphic prototypes of a black powerbook. More than likely it was a designer daydreaming, but a black G5 powerbook...
Holy friggin' voltron, that'd rule!!!! add a red apple to the back of screen and you'd have the most evil mother of a lappie to ever grace the earth!
and they finish the shell with teflon so we can bake eggs with bacon on it
If you take a look at the seven (7) fans blowing across the new G5 Xserve processors, you will realize it will be a little while longer before the technology will make it into a 1 inch thick notebook.
But it will happen, no doubt.
Does anyone actually know how much heat the new 90nm chips produce or are we all just assuming it is a lot simply because the XServe has eight fans?
We know the older 130nm chips are hot because they are in the PM G5s. However, there are a number of reasons why XServes need lots of fans even if the 90nm G5s are not as nearly as hot as we think:
1. The PB G5 is likely to debut with a 1.6GHz chip (or thereabouts) and not 2.0GHz as currently in the XServe;
2. Those blowers need to keep TWO 2.0GHz processors cool, not ONE (as will be in a PB G5);
3. The blowers are designed to be redundant so that if one or two fail the others compensate;
4. The blowers must not just keep the processors cool when the XServe is surrounded by cool circulating air, but also when the XServe is packed into a rack with 25 other XServes all puffing away crunching numbers at full power; and
5. The XServe is likely to have been designed with upgrades in mind so those fans may be keeping two 3.0GHz chips cool by the end of 2004 (thanks neumac for that one)
Your average powerbook with one 1.6Ghz G5 surrounded by cool air and gently surfing the net or playing music (with a fan for when it has to push itself encoding a DVD or processing film transition effects) can presumbly cope with the (less) heat generated without multiple noisy fans.
I seem to remember everyone saying how difficult it would be to put a G5 in a laptop because of the heat generated. Well chips get smaller and cooler.
I beleive that the cooligy thing is a red herring. If heat is generated you still have to move it to somewhere else, you cannot make it disappear unless you can do something REALLY clever like turn it back into battery power. Cooling systems only move heat away from the chip faster and pump more of that heat into your already roasting lap!

If things like that were efficient, our universe would be much different than we know it!
Since chups are getting smaller, technology like Cooligy would fir in the sapace formerly occupied by the larger ship and used in conjunction with current cooling technologies. Effictively making a g5 in to a chip with the heat of a g3!
If things like that were efficient, our universe would be much different than we know it!
Obviously it wouldn't turn back into as much battery power as it started.
Does anyone know approximately what proportion of a laptop's battery's energy currently turns into heat (rather than more useful things like lighting LCDs or spinning HDs)?

Well stated.

when can we see the new pbooks?
stop teasing

Then it WOULD be perfect!!
