从空气中产生饮用水的智能广告牌

有人说，下一次世界大战将是为了争夺水资源。水资源正在以惊人的速度枯竭，科学家们正在努力寻找解决这一困境的办法。在他们继续努力的同时，我们在秘鲁取得了突破。研究人员与一家广告公司合作，为利马饮用水短缺提供可行的解决方案。让你回忆一下，它是世界上第二大城市。饮用水短缺问题是一个严重的问题，需要紧急重视。经过一番认真的工作，研究人员找到了一个可行的解决方案，这个方案非常聪明，而且非常简单;一种能将空气湿度转化为饮用水的广告牌。让我们上一堂地理课;利马市位于世界上最干燥的沙漠阿塔卡马的北部边缘，它周围的村庄每年的降水量几乎不到0.51英寸。 The capital city relied for a long time on runoff from glaciers and drainage from the Andes Mountains. However, climate change has made supply from both sources even scarcer. Here are statistical values for you to comprehend how bad the condition is; out of 8.5 million people who are residents of Lima, 1.2 million are faced with zero availability of running water. Their only options include drawing water out of wells- that water is polluted and it is a known fact- or turn to unregulated private water companies that distribute water via water trucks and charge as high as almost 20 times the normal price of tap water. Quite aware of this problem and its severity, Lima’s University of Engineering and Technology started looking for a way to find a solution to this dire problem. The fact that the city’s average air humidity is 83% because of where its located- along the Southern Pacific Ocean, UTEC joined hands with an advertising agency, Mayo DraftFCB, resulting in the creation and installation of a billboard that produces water out of air- literally. The billboard is first of its kind. Let’s take a look at how it works.

这个惊人的发明是由五个部件组成的反渗透系统。第一步是收集潮湿的空气，第二步是让空气通过空气过滤器进入冷凝器，从而产生水，然后水通过碳过滤器进入中央水箱。人们只需打开安装在广告牌底部的水龙头，就可以得到可以饮用的冷水供应。梅奥发布的视频称，这项创新每天可以生产多达100升的饮用水。在3个月的时间里，该广告牌为利马居民提供了9450升的饮用水。

广告牌也是吸引更多学生来港大学习的一个工具。Mayo DraftFCB的创意总监亚历杭德罗·阿蓬特(Alejandro Aponte)说:“我们希望未来的学生看到工程师如何在日常情况下解决社会需求。”到目前为止，在泛美高速公路89.5公里处只安装了一个这样的广告牌，但想象一下，十几个这样的广告牌会有什么效果!
