"It was my preferred entertainment when I was a kid, so when I set out to be a writer, it was perfectly natural that I should write the sort of stories that I used to enjoy reading."

| Molecular Sieve | ||
| A device that can extract any element from seawater. |
Clarke begins the story by pointing out that a cubic mile of sea water contains millions of tons of dissolved minerals - how best to get at them, when there are only about fifty pounds of gold per cubic mile?
| I put some of my young men to work and they have made what we call a 'molecular sieve.' ... It depends on very advanced wave-mechanical theories for its operation, but what it actually does is absurdly simple. We can choose any component of sea water we like, and get the sieve to take it out. With several units, working in series, we can take out one element after another. The efficiency's quite high, and the power consumption negligible. |

'But the stars are only atoms in larger space, and in that larger space the star-atoms could combine to form living matter, thinking matter, couldn't they?'
'...to build up a video picture would require, say, ten million decisions every second. Mike, you're so fast I can't even think about it. But you aren't that fast.'
'The area affected was five hundred kilometres across, and perfectly circular.'
'Hasan always pitched a Gauzy - a one-molecule-layer tent, opaque, feather-light, and very tough.'
