Water From Air Without Energy

Water shortage:
The Next Global

Water is life’s first necessity. Without water, everything stops. However, water supply is becoming a larger problem every year.  According to the World Health Organisation, water shortages already affect 2.1 billion people around the world. Worse still, by 2050, the United Nations expect that half of the world’s population will experience water shortage. Therefore, many people call water shortage one of the next global challenges.

Looking at nature to
retrieve water from air

Nature has learned over millions of years how to survive in dry, warm areas. The atmosphere contains large amounts of water vapour. In particular in coastal regions. Desert animals and plants absorb this water to survive. Inspired by these animals and plants, researchers have developed a smart material that absorbs water during the night and releases it during the day.

Self-Watering Tree Guards
Collect water from air
to irrigate young trees

Sponsh is scaling up this smart textile for real-life use. The first application is integrating the material into a tree protector (or stem guard), for application in forestation or orchards. This self-watering tree protector absorbs water from air at night. During the day, the protector autonomously releases the water to irrigate the young tree. Ensuring the tree can survive the first harsh summers and grow into a self-sustained large tree.

No infrastructure, water or
electricity lines are required. The material performs stand-alone.

No Energy Needed

Temperature differences drive
absorption and release of water. No electricity or other energy is needed


No large investment required. One square meter already provides daily water.
