Another alternative is to use simpler cooling technology but reduce the cost of it. My team and I have been developing a water-from-air system using old fridges and freezers, in addition to other recycled components such as an old computer fan and a mobile phone charger.

We hope to create a low-cost system for developing countries that also reduces waste in developed countries, particularly when solar panels are used to power the system. Future work in this area would include using special surface coatings to provide a non-stick surface such as the surface of waterlilies for water droplets to be easily collected to create a more efficient system, in addition to ongoing metal-organic frameworks research.

Another challenge is air pollution. In some parts of the world, special filtering and treatment might be needed to make the captured water safe to drink. But this technology is moving fast. Who knows, in the future we might not have to travel to Tatooine to see a Star Wars vaporator in action.

Active cooling Then there are active cooling technologies such as a refrigeration cycle similar to the one we use in air conditioning systems and refrigerators.

The technology, described in the journal Science , uses a network of metal and organic molecules that can easily trap water vapour, which is then released using heat captured from the sun. It has been reported that one kilogram of this material can harvest 2.

This makes it a particualrly promising technology for harvesting water in arid or desert regions of the world. Another alternative is to use simpler cooling technology but reduce the cost of it.
