    Here's my attempt:

    Due to the laws of physics (and several other sciences), as processor manufacturing technology shrinks, more energy escapes the processor as "leakage current" and is wasted. Technologies like SOI (Silicon-on-Insulator) and SSOI (Strained Silicon-on-Insulator) help to keep the energy flowing instead of getting stuck somewhere and escaping. It follows that if more energy escapes instead of doing useful work, more energy will be consumed to compensate.

    And I thought I was smart because I actually understand most of Ars Technica. Now I feel stupid again. Pretty much all I got was, "processor hot!"

    That seems to be a PhD. in duh on the subject of the G5 "processor being hot". When molecules move rapidly in rubbing electrons then heat is produced. So now in our 2.5 model, Apple has a fix with the "water cooling".
