Amazing water technologies
An Israeli (以色列的) water technology company makes machines that create drinking water from air. The machine takes in humid air and cools it, turning the water vapour (水蒸气) into liquid. The water is then cleaned until it is safe to drink. These machines run on electricity and can be used anywhere to provide clean water — without needing rivers or other water sources. Small units for homes or offices can make up to 30 litres of water each day, while larger machines can produce up to 6,000 litres.

There are other smart ideas for getting clean water. Back in the 1990s, Dr David Manz from Canada made a bio-sand filter (过滤器) for family use — a container filled with layers of sand and gravel (石子). It uses good microbes (微生物) to fight and destroy bad ones, removes heavy metals and other harmful things, and also makes the water taste better. Now, the method is used in many places, especially in Africa, Asia and Latin America, where there is not enough water. People can build such filters at home by following step-by-step guides online.

Another popular water filter is a special straw (吸管) made by a Swiss company. It can remove 99.9% of bacteria (细菌) from water. It was originally made for places with water problems, but is now used by many for camping. You can take it anywhere you go, and it’s easy to use — just fill a bottle with any water you can find, put the straw in, drink, and stay safe!
Clean water is really important for staying healthy. Thanks to these cool ideas, more and more people in the driest parts of the world are getting clean water to drink.
