Word on the net is that Apple is working on some cooling related patents, specifically related to venting via the USB and firewire ports. In a way it makes sense, but there’s definitely a potential for disaster. What if all your USB ports are filled up with novelty devices?
Apple Insider actually found four different patents currently processing from Apple; one regarding cooling via the USB and Firewire ports, two regarding a laptop’s ability to sense airflow and make adjustments automatically, and then finally (and most interestingly) a plan to use heat conductive hinge assemblies. While to some this may not seem interesting, the concept of using the lid as a giant heat-pipe definitely shows potential.
