Cloud Seeding
The crystalline structure of β-AgI is similar to that of ice, allowing it to induce freezing by the process known as heterogeneous nucleation. Approximately 50,000 kg/year are used for cloud seeding annually, each seeding experiment consuming 10-50 grams.

Famous quotes containing the words cloud and/or seeding:
“When I from black and he from white cloud free,
And round the tent of Godlike lambs we joy,
I’ll shade him from the heat till he can bear
To lean in joy upon our father’s knee;
And then I’ll stand and stroke his silver hair,
And be like him, and he will then love me.”
—William Blake (1757–1827)
“Propaganda has a bad name, but its root meaning is simply to disseminate through a medium, and all writing therefore is propaganda for something. It’s a seeding of the self in the consciousness of others.”
—Elizabeth Drew (1887–1965)
