1Israeli 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.

2GENNY 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.

3A 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.
