[Excerpt from Wikipedia… ‘…Drinking water has been distilled from sea water since at least about AD 200, when the process was clearly described by Alexander of Aphrodisias. Its history predates this, as a passage in Aristotle’s Meteorologica refers to the distillation of water. Captain Israel Williams of the Friendship (1797) improvised a way to distill water, which he described in his journal.
In chemical and biological laboratories, as well as in industry, cheaper alternatives such as deionised water are preferred to distilled water. But if these alternatives are not pure enough, distilled water is used. If exceptionally high-purity water is required, double distilled water is used. In general, non-purified water could cause or interfere with chemical reactions as well as leave mineral deposits after boiling away. One method of removing impurities from water and other fluids is distillation. For example, ions commonly found in tap water would drastically reduce lifespans of lead–acid batteries used in cars and trucks. These ions are not acceptable in automotive cooling systems because they corrode internal engine components and deplete typical antifreeze anti-corrosion additives…..’ ]
