"I was driving a dynamite truck when I was 14 years old in North Carolina."

| 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. |
