A Bengaluru-based start-up Uravu Labs has made a device to capture water from the air. They, however, have taken a different approach. They have used an air-water extraction system based on desiccation where a saltwater solution called brine is used to remove moisture from the air. Air passes over the brine, and as it absorbs moisture, the brine becomes saturated. The brine is then heated with solar energy to evaporate the water, and the resulting water vapour is collected.
