Water, Water Everywhere, But Not A Drop To Drink

Humans need water to live, plain and simple.

The Rule of 3's survival: Humans can live:
. . . 3 minutes without air,
. . . 3 hours without shelter(In a harsh environment)
. . . 3 days without water,
. . . 3 weeks without food(but you won't be happy)

130 years ago, Louis Pasteur discovered that,
. . . heat of boiling is very effective at killing all microbes,
. . . which cause disease in water.

In Peru, the Ministry of Health urged all residents,
. . . to boil drinking water for 10 minutes.
. . . The cost of doing this would amount to,
. . . . . . 29% of the average poor household income.
. . . . . . 11% of the income of a family in the lowest quartile, in Bangladesh.
. . . The homeless have little. in the way of boiling water in any country.
Yet, heating water to 66o C in a solar cooker,
. . . will provide enough heat to pasteurise the water and
. . . kill all disease causing microbes.

We use water in many things we consume every day:
. . . . . . coffee,
. . . . . . tea,
. . . . . . soup,
. . . . . . cooking, baking, microwaving(just add water).
