I remember the post that someone asked if T-bolts could run on batteries (and I know the answer is no) but someone came up with the idea of Generators, but then somebdy shot that idea down with the answer of "But think about having to go around starting those things up"
Well, isn't there small generators (not the big ones used on buldings that provide like 10 Kilowatts) but a small somewhat portable generator that starts itself in a matter of second after the power goes out? I think I saw one up at Lowes one day, it was a house generator but it wasn't something big or provided a whole butt load of power and started itself in about 3 seconds after the main power failed and it adjusted the engine speed to match the power demand. Wouldn't something like that work on a T-bolt? (assuming the T-bolt is single phase 240 volt)
