Sponsh develops temperature-triggered smart materials, which produces water from thin air using the natural daily temperature cycles. At night, when temperatures are low, the material absorbs water from air and swells up. During the day, when the sun comes our and temperatures go up, the material autonomously releases the collected water. This water can be used to irrigate trees, make drinking water or even dehumidify.
