Using the principles of biomimicry, the Groasis Waterboxx  enables plants to establish themselves and survive even in the most arid regions of the world, just the way nature does it. Pieter Hoff, founder of AquaPro  and inventor of the product, hopes to use the new device to combat hunger, desertification, and climate change.
Hoff has developed a round, 20-inch-wide container crafted from polypropylene that is placed over a two small seedlings. The container is a resevoir for enough water for a full year of micro-drip irrigation. The chamber, which is designed to prevent evaportation, collects rainwater but also maximizes the formation of dew droplets. In some climates dew may be the only frequent source of plant moisture. The Waterboxx design effectively capatures and tranfers condensation into the water reservoir. A wick goes into the ground beneath the box, slowly dripping 50 ml of water to the plant’s root system everyday.
As the plant grows, its roots reach deeper and deeper in the ground, eventually finding their own water source. If all goes well the box can be removed after one year.
Popular Science selected The Groasis Waterboxx as as one of the top 10 inventions of 2010 .
