This device makes sea water drinkable 使海水可以饮用的装置

孙静

馬来西亚的三名学生发明了一种可以使海水变成饮用水的装置。这个装置名叫“水吊舱”（WaterPod），它的模块化设计为创建WaterPod网络提供了便利，该网络可以为整个社区提供饮用水。

Humans have flown to the moon andmay even make it to Mars. But providingclean water to all remains a challenge. TheWorld Health Organization estimates thatone in three people globally still do not haveeasy access to clean water.Whiledesalinat-ing（淡化） ocean water is an obvious solu-tion， the current process is both expensive and harmful to the environment. Now，someMalaysian students may have found a cheaper and more sustainable way to transform seawater into drinkable water.

Bennie Beh Hue May，Loo Xin Yang， and Yap Chun Yoon of the Asia Pacific Uni-versity of Technology & Innovation came up with the idea of WaterPod after observingthe hardships of ethnic groups likethe Sama-Bajau. They live in the shallow waters offthe coast of the Philippines， Malaysia and Indonesia. While the ocean provides the leg-endary divers with plenty of food， they often have to exchange goods with nearby communities to obtain fresh water.

Made of recycled plastic waste，WaterPod is designed to draw water from the sea with minimal salt intake. The salt that remains is filtered （过滤） through a process in the clear plastic-covered， dome-shaped container at the top. The sustainable，self-cleaning device can work as an individual unit of sea water desalination.However，its modular design also allows for the creation of a network of WaterPod that could provide water for entire communities.

The clever device beat 120 entries to winthe national James Dyson Award in Malaysia on August 25，2021. The team then competed with 84 finalists worldwide for the international 2021 James Dyson Award. The annual contest aims to encourage stu- dents to develop unconventional ideas to solve real-world problems. The winners，an- nounced by the end of 2021， had received a cash prize of $38，167 and an additional $6，440 for their university.
