Converting air to water, a futuristic invention of Tunisian engineers – zimo news


While global warming is depleting drinking water resources, Tunisian engineers have showcased a machine capable of converting dry air into water at the French technology innovation fair Vivatech.

When entering the Vivatech fair at the Porte de Versailles in Paris on June 17, 2022, visitors immediately see an interesting object reminiscent of the robotic therapist from Star Wars or the famous Pixar movie Wall-E .

An egg-shaped, all-white one with a tap and a small touchscreen. At the top is a small chimney that hums slightly. One of the two founders of the Kumulus company, Iheb Triki, smiled and waited next to his creation. It is a dew generator: an object capable of converting dry air into water.

filter sequence

easy to use. It is a series of filters, specifying Iheb. ” First filter particles in the air. After that, this air enters the refrigerator compartment. This is where the dew phenomenon occurs. Then the air moves on. Water produced through the phenomenon of dew passes through one filter to filter particles and a second filter to filter bacteria before being mineralized and then stored. »

Appliances are mainly made of easily recyclable materials: stainless steel and aluminium. The fuel tank keeps filling up. In Dubai, the machine can produce an average of 40 to 50 liters per day. Deep in the Tunisian desert, ten liters.

Thus, one unit of this innovation can supply water to about 10 or even 30 people depending on the location. So many people will therefore consume less plastic, have their own water source even in the desert, and avoid transporting plastic bottles.

Subscription system

However, the price is not communicated because the machine cannot be bought, it is rented. Iheb clarifies: We are not selling machines, we are selling water. So all of a sudden, when we give you the machine, you pay us through our web app for the service behind it, the filter replacement, the maintenance, the monitoring, but most importantly the water quality tests we do daily and monthly . » According to the company, the price per liter is 10% to 20% cheaper than water mineral in a bottle.

Therefore, the present invention is not directed to individuals, but to groups. Kumulus targets NGOs, companies, local authorities and even the construction industry…and sometimes with surprising results. ” We tested it next to a chemical plant. Pollution is invisible, but it is in the air. Water is fine.The reason is simple: there are adequate filters, but condensation means that certain particles, especially heavy metals, are naturally filtered ‘ said Iheb Triki.

With a machine inspired by vintage jars, Kumulus hopes to attract customers from the African continent and the Middle East despite the subscription system.
