where is this going in the short term?, page-24

"I dont want to be doomsayer but surely you can immagine a scenario when national power grids cannot operate because of solar flares or one hundred other reasons and these standalone systems favour those who seek independance."

Topdad - without stating what I see as obvious (and someone can correct me if I am wrong) but if the power grid is out - how do they pump gas into houses? Aren't the pumps need power to work? Or is it all pressure driven?

I apologise if I'm wrong, but do not think they can work if no Gas to the houses.
