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. Dean
