In many parts of the world there may not be much precipitation, but there is a fair amount of water vapor in the air – particularly at night. An experimental new device draws in that vapor, then uses it to irrigate edible plants.
Known as the SmartFarm, the small-scale prototype was designed by a team at the National University of Singapore, led by Asst. Prof. Tan Swee Ching. It s essentially a transparent acrylic box that has kangkong vegetable plants growing in soil on the bottom – on top, a hydrogel panel lies beneath a solar-powered motorized cover.
The copper-based hydrogel is very absorbent, readily drawing water vapor from the cool night air while the cover is open. An integrated timer closes it at dawn, with the sun s rays subsequently heating the hydrogel through the clear cover material. The gel responds by releasing its stored water in the form of vapor, which condenses into liquid on the inside of the cover.
