: For that long of a time you may want to look into some sort of backup
: generator. You can get ones that run off natural gas for a few thousand
: dollars.

A generator (with all the attendant noise, fumes, $$$$, &c.)  may be
overkill if the machine is drawing less than a KW.  (I'm not familiar
with the machine.)

You can go to GI Joe's (here in the U.S.A.) and buy a 1 KW
12V DC --> 120V AC inverter for $150.  You can then go to Sears
and buy a "deep-charge" 12V  Rec. Vehicle battery for another $100 or so.
This will give you a substantial (don't know exactly how much) number
of minutes of high quality AC to run your computer.  Another N × $100 or
so buys N more batteries which can be hooked in parallel to 
multiply your original time by (N+1).

The only incomplete parts of this is the switch-over mechanism and the
auto shutdown.  They make swithover devices for generators so the same
device shd. be able to be used here, I suppose.
