Well, not quite yet --
We've had about 5 short term power loss episodes so far; those of you in the Northeast may understand when I say... we're on the verge of an ice storm. Temps in the low 30a, rain/sleet/snow ... and the birch and pine trees trees are drooping and bending under the weight of the ice. That means we've got a real good shot of losing power for real when one of the birch trees breaks onto a powerline. We *do* have about 5 UPS around here, mostly charged, so we could carry on computer wise with laptops if need be...
But, I'm ought here for the moment.

2004-12-11 06:59 (UTC)I'm at least looking at getting an inverter -- one of our neighbors managed to save a refrigerator and a big freezer's worth of food throughout the big ice storm we had by running a line from his truck and running them a few hours a day....
What we do have is something I picked up at VIP Auto -- it's essentially an undedicated battery-back-up that can also be used to hot-shot cars. We also have a big pile of batteries; once or twice a year I take a hike through local discount stores looking for battery sales and buy a dozen or two. Right now I'm low on AAA batteries, and probably need to get in some D cells, but we're good for the moment.

2004-12-11 08:37 (UTC)Compared to a consumer UPS, you can run stuff for a long long time on a car battery.
Also, if you have a big solid 12VDC source, you can run DC-DC voltage modifiers which are usually more efficient than an inverter plus a transformer block (as long as the final output is DC)
I know this more from running accessories off (the) battery power on my buses than power outages here (infrequent but massive[1]). At home when the power is out, I don't try to run the computers (very power inefficient setup), and everything else can survive with not power. At night, I dig into my camping gear for an LED headlamp (100+ hours on 2 AAs), and a 12LED camp lantern for area lighting (runs on 4 Ds for a long long time[2]).
Good luck with the ice storm, those pretty much sucked when I was growning up in NC.
[1] Last major power outages: earthquake, human error[3] and human error [4].
[2] In the process of modifying one so that it runs off 4 AAs and fits under 4oz for back packing.
[3] For safety reasons, when you are doing work on a substation, you isolate it from the grid and ground it out. When you put it back online, it is a good idea to disconnect the grounding cables...blew fuses all up and down the Peninsula.
[4] Fire alarms do no good if they are ignored or turned off. A small smouldering fire at the unattended Mission substation (40% of SF) was disregarded by remote operators until the smoke got so bad that there was massive arcing and damage at the substation.
