Solar Water Distiller

This nifty devise produces up to 5l/day. Might not be bad to have as a back up.

Milan-based designer Gabriele Diamanti's "Eliodomestico" solar-powered eco-distiller was recently selected as one of 12 finalists for the Prix Émile Hermès 2011. The small, vat-like still is made entirely from terracotta and zinc-plated metal sheets, and, in keeping with the Italian designer's intention for "Eliodomestico" to be completely open source, "it's designed to be produced (and eventually repaired) by local craftsmen."
