Steve, I don't think you're going soft, just a little silly in the head! Steve said, "For example, the building I work in has a fountain powered by solar energy. During a cloudless summer day you get a pretty good fountain. By about 6 or 7 PM it is hardly going at all, and once the sun has set all you have is a calm pool". Don't know about everybody else, Steve, but I'd say that the most "use" you could get out of a fountain would be during the day!! What's the point in running it during the night? (or at all?!) In fact this rule will apply to other energy uses. O.K. so solar power might not be able to supply all needs at all times but we could start by powering buildings etc. which are used mainly in the daytime (i.e. business/industry buildings) especially as industry could probably better bear the initial capital costs. So there, you nasty man!
