The Kumulus-1 generator draws drinking water from the air without the need for electricity. Sized like a compact washing machine, this device can yield up to 30 liters of potable water each day. It represents a promising advance for producing drinking water in places where resources are scarce.
Created by a team of Tunisian engineers, the invention focuses on converting air humidity into drinkable water. While other devices perform a similar feat, Kumulus-1 achieves a level of efficiency that stands out in the field.
The system offers a clean, reliable source of water in regions prone to drought, including parts of North Africa. It proves particularly useful for schools and towns without reliable access to potable water, and it also suits factories, offices, and hotels seeking to reduce groundwater or bottled water usage to limit plastic waste.
The working principle is straightforward: it mirrors the morning dew process inside. The device extracts moisture from the air, cools it, and condenses it into water stored in an internal tank. A top-mounted filter removes contaminants to ensure the water is fit for drinking.
The first unit was installed at a rural school in El Bayadha, a community where water access is limited. The installation was welcomed with joy as the system supplied about 30 liters of water daily to the school.
The machine’s standout quality lies in its fully autonomous operation, requiring no connection to a power grid. It runs on a photovoltaic solar panel that generates the electricity needed for the process, enabling placement in diverse settings.
The company notes on its site that roughly 1.0 billion people worldwide lack access to drinking water, and about 31 percent of the world’s schools face the same challenge.
Kumulus-1 suggests a practical approach to a daily global problem, potentially reducing the risks associated with poor water quality for millions of people.
