Salt water is provided to a hydrophilic evaporating support surface, preferably of woven cotton or fine wire mesh placed to receive heat from the heat source preferably solar energy, and release water vapour. Water vapour condenses on a cooled condensation surface located within the container. Fresh water is collected from the condensing surface as it condenses.

Why it's free to use
- Filed May 11, 2001 and granted December 24, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 11, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 11, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
