Comment Power factor? (Score 2, Insightful) 400

I wonder if this analysis took into account CFL's poor power factor. Cheap CFLs usually have a power factor of around 0.5, which causes substantial electrical losses compared to Incandescent bulbs, which are purely resistive (and therefore have a power factor of 1.0). LEDs, on the other hand, have a pretty good power factor. http://www.theengineer.co.uk/opinion/led-is-the-answer/299821.article

A couple years ago we discussed Benjamin Heckendorn's modification which turned the Xbox 360 into a laptop. Now, he's completed a new, revamped design which includes a removable Xbox 360 hard drive, an internal Wi-fi module and a new button layout. It looks a lot nicer, too. He's also posted a description of how he did it.

"Human-rights groups say that more than 3,000 villages have been destroyed in an effort to crush opposition to the junta. Civil unrest in Myanmar has created 1.5 million refugees and 500,000 internally displaced people, and 1,300 political prisoners are in jail, according to human-rights reports.""
