The Null Device

The SUV of the living room

Surprise of the day: large-screen TVs use more current than the smaller ones. Wal-Mart America's love affair with the jumbo plasma screen has resulted in massive increases in electricity consumption, calling on some to compare the TVs to that other emblem of the divinely-sanctioned and non-negotiable American lifestyle, the SUV. The fact that a lot of people leave the TV on 24 hours a day as a psychological security blanket probably doesn't help.

(Though is anybody really surprised that large TVs use a lot more current? Electricity consumption would, I imagine, be a function of the square of the screen size, meaning that even small increases in size result in large increases in power consumption. Which, also, is probably one of the reasons why small, wimpy-looking laptops have about twice the battery life of the larger, more-impressive-looking ones.)

Is that why small wimpy looking youths have twice the brainpower of their more athletic looking peers?

Actually, I think you may be on to something there...

Actually, I'm wondering how flat-screen monitors compare with CRTs, in terms of power consumption.

They consume a lot less, apparently. (Doubly so if you need air conditioning to get rid of the heat a CRT puts out.)
