Peter Hoff has designed the ultimate device to combat problems like global warming and soil erosion- the ‘Groasis Waterboxx’. It is a 20-inch wide container made from polypropylene having a very simple working. Rainwater and condensation get trapped inside this container. A wick goes from the bottom of this container into the ground through which water drips on to the roots of the plants, supporting their growth till they reach deep enough to get their own water source. After the plant has crossed this stage the box can be removed. While testing his invention in the Sahara desert, Hoff observed that 90% of the plants grown using the Waterboxx survived even after removing it.
The Waterboxx is a great example of a very simple yet extremely useful green innovation. Hoff also plans to make a biodegradable Waterboxx which will gradually decompose releasing nutrients into the soil.
