The government recommends that you storing at least a three days supply of water for each person residing in your primary dwelling; but 7-14 is a better preparedness practice. Having water on hand is excellent but knowing how to collect water from the environment is a necessary preparedness/survival skills as water can become scares after a disaster hits and clean water may be hard to find in a wilderness survival situation.
On the 6th we talked about various water collection techniques including plans for more somestic/semi-perminante systems such as using a Water BOB, constructing a Gutterless Rain Barrel (because we don't have gutters), and Driving Your Own Fresh Water Well; we also researched wilderness survival collection techniques to include a Transpiration Bag, which we tried on the 7th.
www.biology-online.org defines transpiration as (botany) The loss of water by evaporation in terrestrial plants, especially through the stomata (leaf pores), accompanied by a corresponding water uptake from the roots; a process in which the water vapor escapes through the plant via its stomata and lenticels (a loosely-packed mass of cells in the bark of a woody plant) into its external environment (atmosphere).
www.dictionary.com defines it more simply as: (Botany) the passage of water through a plant from the roots through the vascular system to the atmosphere.
Even more rudimentary put, by the eldest son, "So, essentially, we are gathering plant sweat in order to drink it". Ummm... yeah, that's about right.
So, a Transpiration Bag is simply the collection of the evaporated water from foliage. How do you accomplish this exactly? Like this: Transpiration Bags for Water Collection.
