Solar Stills

Solar stills can provide the extraction of potable water from contaminated or brackish sources through solar / thermal action. Knowledge in their use provides a vital tool to use in certain situations where a solar still would be beneficial. From extracting potable water from non-poisonous plants to removing salt from seawater, solar stills have been in use for many years and have saved many lives. But remember, there is a cost-benefit analysis that must be done if the energy required to build a solar still outweighs the potential water that can be accrued depending on the location of the still and other factors. Know their proper use to make informed decisions about using a solar still.
