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:
“On a cloud I saw a child,
And he laughing said to me,
“Pipe a song about a Lamb”;
So I piped with merry chear.
“Piper pipe that song again”—
So I piped, he wept to hear.
“Drop thy pipe thy happy pipe
Sing thy songs of happy chear”;
So I sung the same again
While he wept with joy to hear.”
—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)
