INNOVATION. Mostiglass, a revolutionary mosquito net that refreshes the air

The invention of this couple of scientists from Bordeaux has nothing to do with conventional mosquito nets. These are transparent perforated plates that naturally cool very hot air. Thanks to a venturi effect. explanations. (article published on 03/06/2022)

It was a friend who told me about it and since mosquitoes invade me in summer, I was very interested” David, a medical intern, entrusts us, who today receives the pair of captains who have come to ask him for their ” Mostiglass“.

The transparent panel will not obscure your apartment located on the ground floor. It is pierced with horizontally arranged oval holes, tapered in depth.

They are big enough to let air through and small enough to keep mosquitoes away.explains François Capitaine who assures that his invention is 100% effective against the tiger mosquito, ” this has been validated by a WHO accredited laboratory“.

What does not happen either, and this is where all the innovation is, is the heat. The holes are shaped in such a way as to produce a venturi effect.

“It’s a well-known process in physics.” specifies Nathalie Captain. ” The air is accelerated in the hole and the pressure decreases, which lowers the temperature. At 20 degrees the temperature remains the same.

But at 29 degrees there will be a drop of 4°, that is, the air that will enter the interior will be at 25° and the hotter it is outside, the greater the temperature difference. Important”.

The couple, she a physicist, he a materials chemist, spent a few years developing the product. With the support of the start-up incubator Unitec and from the Region of Aquitaine, they obtained a grant of 20,000 euros to manufacture their prototypes.

The engineering school where they graduated, the ENSCBPagreed to organize his first workshop.

They launched the commercialization in 2020, just at the beginning of the health crisis after investing in a machine that allows them to drill holes very precisely. They won’t tell us which one for fear of being copied.

What we lack today is notoriety. We need to make ourselves known in order to develop in France and internationally.“François Capitaine is confident. He sells to individuals, but also a lot to local authorities.

They are interested in nurseries, nursing homes, collective kitchens for health reasons but also for safety reasons because they are extremely solid walls designed in polycarbonate, a material 800 times more resistant than glass. This is the material used for aircraft cabins or eyeglass lenses.“.

Nathalie and François offer all kinds of models, fixed doors, sliding doors,…

Mine it cost me a little less than 200 euros“reveals David, the intern doctor.

The pair of inventors should not have too much difficulty entering the market. In fact, the scourge of the tiger mosquito is not ready to disappear…
