One look at our Planet shows that more than 70% of the global surface is covered by Water.
97.2 % of Earths total Water Reserves are covered by Oceanic saltwater and therefore mostly inappropriate for Human consumption and use. The remaining 2.7% of freshwater is equally unavailable to Man as it is confined to the Ice of the Polar Caps and Mountain Glaciers. Only Ground Water (0.625 % of Earths total Water Reserves) and the Water from Rivers and Lakes (0.017%) remain easily accessible to Man.

For ecological, economical, geographical and / or political reasons, 40% (2.5 Billion) of the World`s population has no access to Clean Water!

Oral Rehydration Salts (ORS) is a WHO (World Health Organization) recommended compound of salts and minerals which are added to the condensed water. If salts and minerals are not readily available, one can add 1 -1.5 % of sea water to the condensed water to reach the desirable level of minerals and salts. Evidently, one should ensure that the sea water used be unpolluted
