<p>“What we are trying to do is <mark>to make the droplets inside the clouds big enough so that when they fall</mark> out of the cloud, they survive down to the surface,” explained Keri Nicoll, one of the core investigators on the project.</p>
<p>The technique has successfully created rain over Dubai and has even resulted in safety warnings for drivers over slippery roads.</p>

<p>Suite de mes réflexions vis-à-vis de l’eau, des <a href="/david/2021/06/27/" title="Sécheresse">sécheresses</a> et de sa <a href="/david/2021/07/10/" title="Eau virtuelle">virtualité</a>. Ici, on arrive tout de même à une technologie qui permettrait à une localité de récupérer l’eau avant qu’elle arrive «&nbsp;naturellement&nbsp;» à un autre lieu. Ça augure de nouvelles tensions géo-politiques. C’est un peu équivalent aux conflits diplomatiques qui existent — dès à présent — avec des fleuves parcourant plusieurs états et des retenues/consommations d’eau en amont qui créent des sécheresses en aval.</p>
