Some interseting topics and ideas about future powerbooks and cooling etc...


Apple's PowerBook roadmap is very uncertain, according to an AppleInsider source, who states that plans for further revisions are still up in the air. "A dual processor G4 powerbook may see the light of day if the engineering challenges of shoehorning a G5 into a 1 inch thick enclosure cannot be resolved in a timely fashion."

Rumors of a dual PowerBook G4 were widespread on the internet several months ago, but saw now official announcement from Apple. The computer maker has reportedly developed prototypes of the dual processor laptop -- based around the G4 processor -- as a precautionary measure.

Meanwhile, Apple is said to be working with a company called Cooligy to try and attain their goal of deploying a PowerBook G5 by May of 2004. Cooligy, which was founded last year by several members of Stanford University’s mechanical engineering department, has developed a cooling method that uses common materials to produce a noiseless closed-loop active cooling system for CPUs, ASICS, graphics chips, and the large programmable gate arrays. According to its Web site, the company plans to sell the technology to "large electronics manufacturers."

The cooling technology is apparently ready to go but it is awaiting safety approval from Underwriter's Laboratories, and other safety bodies in foreign countries, due to the potential for leakage of very hot liquids. AppleInsider first reported on the use of liquid cooling in PowerBook G5 prototypes back in September.

interesting eh? found this at another website..cheers, Mark

imactheknife (which is one of the top 10 best names here in ehMacLand), I see your point re the possibility of this new PB. However, why would it have to be one-inch thick? A 17" PB is quickly becoming a mobile desktop replacement. If there is no specific need for constant mobility, as might be seen in a 12/15" PB, might the 17" model have 1 3/4" thickness if this allowed the Apple designers to put more of the G5 cooling requirements inside this sort of enclosure? I read about the Cooligy technology and the potential it holds for advanced cooling systems.
