Microsoft has been bragging about the energy saving features of its new operating system. But this article explains how Microsoft’s lack of concern for energy saving features led their XP operating system to waste $25 billion in energy of the past five years.

The working assumption of a hundred computers per human being was given a safety margin, and the final estimate to be used in developing an addressing specification was 1 quadrillion (1015) computers connected by 1 trillion (1012) networks. The designers took into account the inefficiencies in address assignment and came to the conclusion that new addresses should be somewhere between 57 and 68 bits in size. Source

Meanwhile, Apple is bragging about being green, but it stands in the way of progress on some fronts. I bought some expensive solar power equipment so I could power my laptop and a few other things on the sun, but I find that I’m obliged to convert from DC->AC->DC in order to power a MacBookPro because Apple is not permitting anyone to make a 12V adapter with the patented MagSafe plug. This means losing energy to heat in the conversion process.

Before Apple gets too cocky about it’s heat generating 85W Mac Book Pro, Apple engineers may want to have a look at the Beagleboard, which can run on solar power.
