Single-chip servers with flash storage could be > powered by flashlight batteries. :) Funny you should mention that. I was thinking about this as I read this thread. A while back (about a year ago, now) I did this. We built a AMD powered server with flash drive and a battery-backed power supply. It worked pretty well and had a tiny power draw. We used these ATX-style power supplies with a built in battery backup. They were rated to run a 'normal' server (with hard drive AND monitor) for like an hour. On our machines they ran much longer. They had a Serial interface so you could tell when they switched to battery and when they were likely to run out of juice. Very neat. They ran great... and I don't think we had an outage that lasted longer than the batteries... I think about 4 hours was the top I saw. I don't work there any more, but I managed to dig up the info... so here it is if you are interested: http://ipps.amsdell.com/ 877-267-3355 IPPSCommander - part number IPAM-002 Ours was customised a bit (different power connector) but they have a 'standard' version.
