[QUOTE="HB13DISH, post: 635379, member: 262829"] Just an idea for heating water in a sunny country. Supposing you have a container of a size which is normally used for solar water heating systems ~120 liters, sitting on the roof top. The container is totally transparent and for the sake of argument let us say it is made of glass (change it later for a less breakable material). How long would it take for the water inside to get to a reasonable shower temperature of 40-50 degrees C? After it gets to this temperature, cover it with an insulating material so that the temperature remains high for as longer time as possible. I could try this with an empty plastic mineral water, which is reasonably transparent. A bank of 60 empty bottles of 2.0 liters would get you 120 liters and would cost you nothing. At least save on the environment as you will be using them instead of throwing them. A normal shower per person can be a lot less than this, but let us say this is for a couple with one child.
