The river water in the farming region of Bujama in Lima, Peru, is so
heavily polluted with metals such as lead, arsenic and cadmium, that
growing vegetables in the area have become heavily contaminated.
Due to this crisis, engineering students at Lima's University of
Engineering and Technology (UTEC) have created a revolutionary
invention that sucks the water from the air to grow vegetables.
students have dubbed their invention the "air orchard".
This ingenious device is fitted with 10 de-humidifiers that filter
water from the air into a drip irrigation system connected to an
urban farm on the ground below.
