荒野求生 - 如何收集乾淨純水

迷失於荒野，最棘手的情況莫過於你有足夠的水源，但這些水卻是未過濾的。我們都知道就算看似再乾淨的水都必須過濾材能飲用，否則將會對你已疲憊的身軀帶來更多的麻煩、甚至死亡。

今天介紹的是蒸餾集水法，這種方法雖然緩慢但是卻可以達到一定的效果。 且最適合用於亞熱帶地區，當氣溫雨水都相對足夠的時候。

首先你需準備兩個杯子或碗，一大一小。

So you have no potable water, no filter, and the big thirst is starting to kick in. Drinking untreated water may give rise to more problems than you already have, but you can distill your own pure water with only a pot, a cup and a clear plastic bag (or maybe a part of your groundsheet). The objective is to encourage water to evaporate from the pot, condense on the plastic and then collect in the cup. Find a sunny spot where your still won’t be disturbed. Place the cup in the centre of the pot and fill the bottom of the pot with untreated water, but not so much that the cup floats.

再來你必須找些石頭與一塊乾淨不透氣的帆布(危急時可用帳篷外帳代替)，如上圖，將小杯至於大杯內，並於帆布四周用石頭固定，最後於小背上方的帆布以一塊石頭壓住。

Cover the pot with the clear plastic. Use a stone to weigh down the centre of the plastic so an inverted cone forms, pointing down toward the cup. 

再來炎熱的太陽與大杯內的水將會因蒸發作用凝結於帆布上，最後將會順勢流向小杯內。屆時就會產生一杯乾淨的蒸餾水。

As the pot warms in the sun the untreated water will evaporate, condense on the plastic, roll down to the centre and drip into the cup. Given sunny conditions, you’ll produce enough water to keep yourself alive while you search for a twist of lemon to liven things up.
