If you don't have Huge UPS needs but much bigger than a big expensive ups, have a look at this: http://tripplite.com/whatsnew/powerverter_aps.cfm The folks at tripplite tell me that this little guy has the same electronics that their ups units designed specifically for computers have. The nifty thing is that you can hook as many 12 volt car batteries onto it as you like, giving you as much backup time as you like. You just need a separate location for the batteries to live (sulfuric acid fumes not to great for computers). Not to mention, a couple of solar pannels hooked up to those batteries, and you've got power for as long as there is sun.

Off of fuel-cell for a moment - as part of this thread was concerned with generator backup. A site to check is www.onan.com Onan has been in power-generation forever - so it seems. They were in use in broadcast - two careers ago for me - and had been around forever when I came across them. Generation available from 2000 watts to 2 million watts, in various fueling environments, gas, LP and diesel. At one time - the BEST UPS had systems paired with Onan generators for a complete package. Not cheap but rugged and reliable.
