A young Cameroonian engineer has developed an air-cooling system made largely from clay, designed to provide an alternative cooling solution in regions where temperatures are high and access to reliable electricity can be limited.
Didier Dinamou, a graduate of the École Nationale Supérieure Polytechnique de Maroua, developed the concept as his final university project. The system was designed in response to cooling challenges faced in parts of the Sahel and other hot regions.
The technology uses evaporative cooling, a process in which hot air passes through moist clay. As water evaporates, it absorbs heat from the surrounding air, reducing the air temperature without relying on a conventional compressor or refrigerant gas.
The use of terracotta is central to the design. Clay is widely available in many parts of the region and can potentially provide a lower-cost alternative to conventional air-conditioning components.
According to descriptions of the project, the system can also support functions such as LED lighting and mobile-phone charging, making it potentially useful in communities where access to electricity is limited.
Dinamou’s project reportedly received a score of 18.5 out of 20 at university and attracted attention for its focus on sustainable design. A final commercial price has not yet been announced.
The engineer’s stated objective is to develop the technology at a cost that could make it accessible to ordinary households rather than limiting it to high-end consumers.
The project highlights a broader challenge in regions experiencing extreme heat: developing cooling technologies that are not only effective, but also affordable, energy-efficient and suited to local conditions.
While a clay-based evaporative cooler is unlikely to replace conventional air-conditioning in every setting, the approach demonstrates how established physical principles and locally available materials can be adapted to address modern cooling and energy challenges.
