on ebay at the moment is an evacuated tube mini oven. It can apparently bake bread and looks like it probably holds about 20 fluid ounces, or a pint. You tube has a video of some-one using a double glass walled tea infuser filled with water and stainless steel wool to boil water in seconds using a fresnel lens with a steel beam, and the cleanrepublic video has 6 foot long lidless glass thermos flasks boiling water on a house wall. The inside of the inner glass wall has a coating that is dark on the outside and reflective on the inside. I would only use one or two of these tube-fuls of hot water in a day, and presumably with lids on the water would stay hot until it was needed. I hope you can buy these in Europe soon, without paying twice the item's worth in postage. It's a Chinese invention from centuries ago, improved on by modern scientists.
I am hoping boiled rainwater is drinkable, with or without the addition of a uv filter, but I've read it has scary things growing in it that can't be got rid of so easily.
