I'm going to design a house with a wind(mill) on top - something that looks a bit like this but its purpose is generating electricity for the house. A modern version of a classic design. Then I'm going to find an architect to do it properly, then I'm going to patent the idea and make a fortune...ooops - did I let out my great idea? It's such a beautiful thing and so obviously of our past that surely no-one can object?
