What puzzles me is that I remember an American alternative energy mag that I came across in the '70s. It was full of clever ways of providing electricity and heating needs from natural resources. It was written simple enough so that even I could understand what to do! Your website caters for people with real engineering/technological skills, and as a simple plumber I think I would be out of my depth. Your photos of the lake were great, and you are very fortunate to live in such a beautiful country. Here in England everything is a whole lot smaller, and we don't have the same conditions that encourage the resourcefulness shown by the Aussies and you Yanks. If I knew how to include pics on this site I would show you some of the area where we live here! Best wishes John Winlow [ Parent ]
