On today’s program, we’ll explore the fascinating science behind atmospheric water generation technology, which generates clean drinking water from the air, and could be an emerging alternative to tackle the global water crisis. The Israeli company Watergen has developed an atmospheric drinking water machine that creates water from the air. The company’s device is a great solution to drinking water scarcity and has gained global attention. It brings clean water to any location at any time and also helps to reduce the carbon created by transportation and environmentally harmful plastic waste. “We actually pull it from the air. There’s humidity, there’s water in the atmosphere all around us and we pull it through our machines.” In the United States, retired veteran Moses West, with his Paladin Water Technology, has worked with the Water Rescue Foundation to bring free clean water to Flint, Michigan, Puerto Rico, and the Bahamas. His AWG units can produce up to 8,400 liters or 2,200 gallons of clean water a day, thus benefiting thousands of people who have no access to clean drinking water. Next, we’ll learn how researchers at the University of California, Berkeley have developed a solar-powered device that can pull water straight from the desert air using the Metal-Organic Framework. “In our latest work, we have the next-generation water harvester. This can work out in the desert where there’s no supply of energy aside from sunlight.” “The key component of this device is this powder. We call it Metal Organic Framework (MOF). It is composed of organic molecules and metals. We leave it overnight because during the night, we have a lot of water content in the atmosphere so the water molecules get inside the framework and stay there.” “We’re going to put the lid on the top of the box to make sure none of the water vapor coming out of the powder can escape from the box. We put the shade on top of the lid to direct the sunlight right on top of the MOF to heat the MOF.” “When this powder heats up, the water molecules come out of the framework, and we can collect them as liquid water.” 今天的節目中，我們將會探索大氣水生成技術背後的迷人科學，它可以從大氣中產生乾淨的飲用水，並可能成為一個新興的替代方案來解決全球水危機。 以色列「沃特金」公司，已開發出一種大氣飲水機，能從空氣中製造水。該公司的設備對飲用水匱乏問題是很棒的解決方案，並已獲得全球關注。它能隨時隨地帶來純淨水，並且有助減少運輸過程中產生的碳及對環境有害的塑膠垃圾。「事實上我們從空氣中提取。圍繞在我們的潮濕大氣中有水分，我們透過設備萃取它。」 美國退役老兵摩西韋斯特，他的帕拉丁水技術公司和水救援基金會合作，提供免費的清潔水至密西根州的弗林特、波多黎各以及巴哈馬。其「大氣水生成器」每天生產多達八千四百公升，或兩千兩百加侖清潔用水，從而嘉惠成千上萬無法取得乾淨飲水的民眾。 接下來，我們將了解加州大學柏克萊分校的研究人員，如何應用「金屬有機框架」開發出太陽能驅動裝置，該裝置可直接從沙漠的空氣中汲取水。「我們最新的研究中，已研發出新一代水採集器。它能在沙漠中，除陽光外無其他能源的地方運作。」 「這個設備的關鍵部分是這種粉末。我們稱之為『金屬有機框架』。它由有機分子和金屬組成。我們讓其在夜間運作，因為夜晚大氣中水含量高，所以水分子進入框架中並被保留下來。」「我們在箱子頂部放上蓋子，確保粉末中散發的水蒸氣無法從箱子中溢出。將遮蔽罩放在蓋子頂部，讓陽光直接照射在『金屬有機框架』上，並加熱它們。」「當這種粉末受熱時，水分子會從框架釋放，我們就能收集成液態水。」 ... https://www.youtube.com/watch?v=KNvbSuf3wL4
