New Computer Powered By PoE
BlakeCaldwell writes "BBC News is reporting about a new PC that's powered via a network cable rather than through a wall socket. The computer only requires 12 watts, lower than the upper limit of 15.4 watts that power over ethernet (PoE) can supply. FTA: 'PoE could end up being a universal power supply system as the cables and connectors for it are the same all over the world. By contrast power sockets and plugs differ by country.'"
I know you were kidding, but wireless power Does exist. T
is 35 watts enough to run most laptops?
Considering that my iBook uses a 65 watt charger, I'd say that 35 is probably sufficient for anything short of the "Desktop Replacement Laptops" (relly more of a portable desktop). My guess is that the laptop will most often run below 35 watts, then trickle-charge the excess to the battery. If the computer needs extra power in the short term, the battery will provide it.

I work for a public university. The people who are accountable for the equipment budget and the people who pay the light bill never talk.
As a student, I worked at several of the computer labs at a large university (40,000 students). One late night when I was closing down, I thought to myself how silly it was to keep the CRT monitors powered on. This was before things automatically shut-off. So I went around to about 200 computers and shut-off the monitors. The next day I got in trouble by my manager...they didn't like my idea at all and didn't care about the heat or electricity savings. Apparently going around to turn them back on in the morning was too much work! I figure for about 6 years (before the advent of auto-shutoff CRTs and LCDs), this university ran > 1000 CRTs 24/7. Anybody care to guestimate how much electricity they could have saved over this time period?
