How big is such a generator?Have I missed something here?, it would cost too much to run electricity to the property (fair enough), but it's viable to run gas to the property?, or are you talking about trucking gas (or indeed diesel) to the property long term.
A friend of mine bought a fairly big generator from an auction a number of years back, I can't remember the size but it was pretty substantial, and was a two stroke diesel. It came from an American Airforce base in the UK - and was presumably sized to power the entire base?. I remember at the time we decided it was big enough to power the town we were in, about 15,000 people.
He sold it quite easily, and made a decent profit.
