Well yes,, It is definitely a consideration. I have thought about this option long and hard. Have picked the brains of people who know about this stuff (handy blokes), and it would seem a good move. I was thinking about just getting one to run the water pump, .. an external plug-in, which would supply water.
Then, the question of powering the fridge arose. Could I get a generator to power the 'fridge'... on a long lead, and only switch the lead over to the water pump when i need to use water.
Hmmmm? Still pondering. I have been advised tho, that I'd have to wire up my house differently if I wanted the whole shebang going, AND, that if I choose to go with a smallish generator, the main concern is that if it doesn't get used, by the time I need it, it may be no use, because, once up, you need to use them regularly. So hmm yes, still trying to work out best option.
As for the copper network.. these grey boxes leeching the copper are being installed in my general area at the moment.

They are along roads..

.. can you imagine ?? a drunk driver.. oh oh.. ooops DOWN it goes.
