I did ramble on somewhat in a couple of posts here, but bottom line is everyone needs to look at their own system and determine what can get their livestock through an extended power outage. Really depends on your particluar set up. Anything from a battery operated air pump to a 5KW generator and everything in between (batteries, inverters, UPSs, combinations thereof) can work. No one can predict when an outage will occur and how long it will last. You buys your gear and takes your chances. How valuable are your critters to you? While I personally don't have one yet, I still believe a generator is your best insurance and bang for your buck for any situation that may arise.
