We all know the world is facing a water crisis, but a new invention could revolutionize how we collect and store water. Scientists have developed a salty gel that can be used to harvest air humidity and store it for later use. The gel, developed at the University of California, Los Angeles (UCLA), is made up of salt, water, and a few other components. When exposed to air, the gel absorbs the humidity and stores it until it is needed. This could provide a valuable source of water for areas that are prone to drought or lack access to potable water. The gel can even be used to collect dew in the morning. This could be revolutionary for farmers in dry climates, or for anyone living off the grid. The technology is still in its early stages, but the potential applications of this salty gel are exciting.
