以色列Watergen公司生產了一种可以利用空气生产干净的饮用水的设备。
1 Israeli company Watergen has made a device(设备) that produces clean, drinkable water out of air. The device called GENNY is small enough to be used in a home or office but can generate up to 30 liters of water a day. The water that GENNY produces is not only clean enough to drink, but also often cleaner than tap water.
2 GENNY takes air in and passes it through a filter(过滤器) to remove dust and dirt. The filter is powerful enough to work even in areas with high air pollution. The air then passes through a chamber where heating and cooling cause water vapor(水蒸气) in the air to change into water. This water is then passed through several more filters and minerals (矿物质) are added to make it healthier and taste better. Finally, the water is stored in a tank where it is continually circulated to keep it fresh.
3 A larger model, called the GEN 350, can produce up to 900 liters of water per day. The GEN 350 is now being used in hospitals that previously did not have a reliable source of fresh and clean water. Watergen has also developed an emergency response vehicle (ERV) that can carry a GEN 350 unit wherever it is needed. In addition to the GEN 350, the ERV carries a generator that supplies electricity for the GEN 350.
4 Watergen s ERV is designed to bring water to people who are suffering from the effects of a serious earthquake, fire, flood or other situations. Once such incident occurred in Northern California in 2018. A fire started at a camp site and spread quickly over a wide area, destroying many thousands of acres of trees and many homes. The town of Paradise, California, was hit particularly hard. One of Watergen s ERVs was driven to Paradise, where it provided water for its citizens and rescue workers.
