Hannah Gelbart: 我主持了这个关于雾气收集的播客节目，讨论了这项技术如何帮助缓解世界上一些最干燥地区的缺水问题，特别是智利阿塔卡马沙漠。这项技术通过利用网捕获雾气中的水滴，然后将水收集起来用于饮用和灌溉等用途。
Vic Gill: 我是BBC的科学记者，我解释了雾气收集器的工作原理，以及这项技术在世界各地，特别是南美洲沿海地区和摩洛哥的一些农村地区是如何使用的。雾气收集器的工作原理很简单，它利用一个细密的网来捕获雾气中的水滴，然后将水滴收集起来储存在水箱中。这项技术可以根据需要进行调整，以满足不同社区的需求。
Monica Denemy: 我来自Water Foundation，我们主要在非洲和拉丁美洲工作，我们设计了一种名为“云鱼”的雾气收集器，它采用3D网，比平面织物更有效地捕获水滴，设计灵活，能够承受风压，经久耐用，无需电力，几乎无需维护，可以为附近的社区提供饮用水。
Arturo Vittori: 我是Walker Water的创始人，我们主要在埃塞俄比亚、坦桑尼亚和海地等地的农村社区工作，我们建造水塔来捕获雾气和露水。水塔是一种轻型垂直结构，由竹子等当地生物可降解材料制成，通过凝结被动收集空气中的水分，无需电力或完整的基础设施，完全离网运行。

Vic Gill: 'It's actually really simple. It's a net to catch fog fundamentally.'
Monica Denemy: 'Cloudfishes are installed in locations where there is regular fog and wind.'
Arturo Vittori: 'The tower is a lightweight vertical structure made from biodegradable and local material such as bamboo, natural fibers and it functions by passively collecting moisture from the air through condensation.'
Deep Dive
Fog catchers, giant nets trapping fog for water collection, are being explored as a solution to water scarcity, particularly in arid regions like the Atacama Desert in Chile. Research suggests scaling up this technology could meet the water demands of entire cities, offering a potential game-changer for communities lacking access to clean water. The method's efficiency and the water's purity are discussed.
- Fog catchers are giant nets that trap fog droplets and collect freshwater.
- A study in Chile suggests fog catchers could meet the water needs of Alto Hospicio, a city with extremely low rainfall.
- The collected water is clean and drinkable, suitable for drinking, irrigation, and even urban agriculture.
