The Longest, Thinnest
Country on Earth
A curious traveller, two wise mentors, and a ribbon of a country four thousand three hundred kilometres long and barely a hundred wide — with the driest desert on Earth at one end, walls of blue ice at the other, the world's clearest night sky above it, and a quarter of the planet's copper underneath.
The Country That Would Not Fit on the Desk
Charlie's question for this whole book: One country holds the driest desert on Earth, walls of glacier ice, the clearest night sky anyone has found, and about a quarter of the world's copper. It also sits on the seam where the sea floor dives under a continent, so the ground shakes harder here than almost anywhere. What do you build when your luck arrives in such strange pieces — and how do you keep it from being only luck?
MISSION ➊ How is a DESERT and a GLACIER the same country? ➋ Why copper? ➌ Charlie left a coil of wire on my desk like a clue. ➍ Norway had one big lucky thing. This place has FOUR. Does that make it easier or harder? 🤔
Mountains at the End of Every Street
The shape is the first fact about this country: about 4,300 km from top to bottom and only 177 km wide on average. Nineteen and a half million people live along it, and roughly four in ten of them live in and around one city — a valley cupped between a mountain wall and the sea.
Day one. 🏔️ Mountains at the end of EVERY street. Painted staircases 🎨. 4,300 km long and 177 km wide — it's a corridor! Nearly HALF the country lives in one valley. Valentina says the mountains explain everything. We'll see.
The Place Where It Does Not Rain
Here is why it is so dry. A cold ocean current runs up this coast from the far south, and cold water makes fog, not rain. Behind that, the Andes block every cloud coming from the east. Parts of this desert average under 1 mm of rain a year, some spots have gone decades without measurable rain, and it has been arid for millions of years. The same clear dry air gives this desert the strongest sunlight measured anywhere on Earth.
🏜️ NO RAIN. Some weather stations have never measured any. Cold sea = fog not rain, and the Andes eat the clouds. AND the same dryness = the strongest sunshine on the planet ☀️. Nature gave them a problem and the answer to it in the SAME parcel. (Bangladesh: the flood brought the soil. SAME TRICK.)
The Other End of the Ribbon
This ribbon is stretched across a seam. Just off the coast, the Pacific sea floor slides beneath South America — which is why the country has more than 2,000 volcanoes with about 90 of them active, why the highest volcano on Earth (6,893 m) stands on its border, and why the ice fields of the far south are the largest ice outside the polar regions in the southern half of the world, about 12,000 square kilometres. One process built the mountains, the volcanoes, the earthquakes and the copper.
🧊 The far south gets ALL the rain the desert never sees. Ice fields the size of a small country. 🌋 2,000+ volcanoes. And it's all ONE machine: the sea floor diving under the land. Mountains, volcanoes, earthquakes, copper — same engine, four different bills.
The Desert That Was Worth More Than Gold
Mapuche and other peoples farm, weave and trade; the Inca push south and are halted.
Spanish rule in the centre; the Mapuche keep their land south of the Biobío for 300 years.
Independence.
Atacama nitrate boom: taxes on saltpetre pay for around half of the government.
German chemists learn to make nitrogen fertiliser from air. The desert's monopoly ends.
The nitrate towns empty. Copper becomes the country's income instead.
Congress votes unanimously to make the great copper mines national property.
A coup, then seventeen years of dictatorship.
Fifty-six people in every hundred vote 'No', and the country changes hands with pencils.
Fruit, salmon, wine, telescopes, solar and lithium — and copper still about half of exports.
For forty years this desert had a world monopoly. Nitrate — saltpetre — made fertiliser and explosives, and taxes on it paid roughly half of all government revenue around 1900. Then between 1909 and 1913 chemists in Germany worked out how to make nitrogen fertiliser out of thin air, and the monopoly simply evaporated. The towns were abandoned; two of them are now World Heritage sites. A single invention somewhere else can close an industry here.
💰 They got RICH on desert rock (nitrate) — half the government's money! Then GERMANY (my Book 13!) learned to make it out of AIR and the towns emptied. Someone else's laboratory ended their boom. ⚠️ Nobody in those towns could have seen it coming. Write that down twice.
Copper, and a Country Changed With Pencils
This is the honest beat of the book. From 1973 to 1990 the country was ruled by a dictatorship; later truth commissions recorded more than 3,000 people killed or made to disappear and tens of thousands imprisoned. In 1988 the country was asked to vote yes or no on continuing, and 56% voted No. Power changed hands, peacefully, on counted ballots. Democracy was not returned to them — they went and got it, with pencils.
🪨 Copper replaced nitrate — and in 1971 EVERY member of congress voted to make the mines the country's own. 💔 Then 17 years of dictatorship; a wall of 3,000+ names. ✏️ And in 1988 they ended it by VOTING. 56 to 44. Estonia sang their way out. They pencilled their way out.
Why the World Needs This Rock
Copper conducts electricity better than any common metal except silver, and it does not care how often you bend it — so the electric world is wired with it. This country mines about a quarter of the world's copper and holds the largest known reserves; the biggest copper mine on Earth is here, and the biggest open pit ever dug is here. An ordinary car carries roughly 20 kg of copper; an electric one carries three to four times that.
🧲 Wire + nail + battery = MAGNET. That's the whole secret: copper CARRIES electricity better than nearly anything. ¼ of the world's copper is from here. An electric car needs 3-4× the copper of a normal one. ⛏️ 2010: 33 miners, 700 m down, 69 days, ALL came up. And the mines drink the SEA now, pumped uphill.
How to Live on a Floor That Moves
In 1960 this coast produced the strongest earthquake ever recorded anywhere: magnitude 9.5. Its wave crossed the whole Pacific and reached Japan a day later. Engineers studied what stood and what did not, and the building rules were rewritten — again and again. In 2010 a magnitude 8.8 struck: it released around 500 times more energy than the magnitude 7.0 that hit Haiti the same year, and it killed 525 people, while that smaller quake killed well over a hundred thousand. The difference was not the ground — it was the rules.
🌍 1960: magnitude 9.5 — the biggest earthquake EVER MEASURED. 2010: 8.8 — 500× the energy of Haiti's 7.0 the same year, and 525 deaths instead of a hundred thousand+. Same planet. Different BUILDING RULES + drills. ← Bangladesh's cyclone shelters ALL OVER AGAIN. Ordinary boring rules beat the Earth.
The Best Sky in the World
Telescopes need dry, still, dark, cloud-free air, and this desert has more of it than anywhere. So the world came: an array of 66 dishes at 5,000 m, four 8.2-metre mirrors on a coastal peak, and a telescope with a 39-metre mirror under construction — the largest optical eye ever made. By around 2030, roughly 70% of the world's big-telescope power will be standing in this one desert, along with the engineers, universities and students that follow it.
🔭 THE SKY IS A RESOURCE. Nobody dug it up or planted it — it's just DRY, HIGH, STILL and DARK, and that turns out to be worth billions. ~70% of the world's big telescopes will be here. 🌌 I saw the Milky Way as a RIVER. Villages point their lamps DOWNWARD to protect it. Best rule ever.
Summer in the Middle of Winter
Being in the southern half of the world used to mean being far from everything — now it is a delivery date. This country is the world's largest exporter of cherries — more than half a million tonnes in a good season, with roughly nine in ten going to China — plus grapes, blueberries and wine (a top-five wine exporter). Salmon are not even native here: farming them was learned from Norway in the 1980s, and this is now the world's second-largest producer. None of that is in the ground: it is a calendar plus a cold chain.
🍒 THE SEASONS ARE UPSIDE DOWN AND THAT IS THE PRODUCT. Their summer = our winter, so their cherries arrive when nobody else has any. Biggest cherry exporter on Earth, ~90% to China. 🐟 And the salmon came from NORWAY (last book!) — not native at all. They imported an industry and made it their own.
Sun, Salt and Batteries
The two things the electric world needs most are copper and lithium, and this desert has both. The country holds the largest known lithium reserves on Earth and produces roughly a quarter of the world's supply, evaporated by sunshine in ponds. That same sunshine, the strongest measured anywhere, has taken solar and wind from almost nothing in 2013 to more than a third of the country's electricity, and the old coal plants are closing. The emptiest land in the country turned out to be the most useful.
☀️ The desert is a POWER STATION. Solar+wind: nearly zero in 2013 → over a third of electricity now. 🔋 Biggest lithium reserves on Earth, dried out by the sun for free. Copper + lithium = every battery and motor in the world. The 'useless' end of the country is now the valuable end. 😳
What Could Switch It Off
Read the chain slowly. A diving sea floor built mountains, volcanoes, earthquakes and copper; a cold current and a rain shadow made the driest desert and the clearest sky; nitrate made a fortune until a foreign laboratory ended it; copper replaced it; a dictatorship was voted out with pencils; earthquake rules turned a 9.5 country into a place where towers stand; and the upside-down calendar, the sun, the salt and the sky each became an industry. Every single step was a decision about what to do with an accident of geology.
⚠️ THE CRACKS: the longest drought in ~1,000 years · mines, farms and cities all want the SAME water · copper and its products are about HALF of exports · plantation fires every summer. Charlie: what would SWITCH IT OFF? Water. And one-metal-itis — which is Ireland's potato problem AND the nitrate towns. Third time!
A Ribbon, and What Was Done With It
🪨 A quarter of the world's copper, and the reserves to follow
The biggest copper mine and the largest known reserves on Earth, plus a state company and a hundred years of mining engineers. The rock cannot be moved to a rival country.
🏗️ Buildings and children who expect to shake
Sixty-five years of rewriting the code after every big earthquake, plus drills everybody has walked. In 2010 a magnitude 8.8 killed 525 people while a far smaller quake elsewhere killed over a hundred thousand.
🔭 A sky no amount of money can buy
Dry, still, dark air above the cloud line. By about 2030 roughly seventy percent of the world's big-telescope power will stand here — and the scientists, universities and students follow the telescopes.
🍒 Summer delivered in the northern winter
The seasons are upside down, so cherries, grapes and blueberries arrive when the rich half of the world has none. Add cold stores, ports and inspectors and geography becomes a delivery date.
⚠️ THE CRACKS: one metal, and not enough water
Copper and its products are about half of all exports — exactly the fragility that ended the nitrate towns when a German laboratory made their rock obsolete. The country is in its longest drought in a thousand years; mines, orchards and cities draw on the same rivers; and the plantations burn hotter every summer.
No president made this country and no mine did it alone. A diving slab of sea floor, a cold current, a rain shadow, sacks of desert crystals, a foreign laboratory that ended them, a unanimous vote, a wall of names, a pencil in 1988, building codes rewritten after every earthquake, a tilted planet, cold stores, telescope mirrors and evaporating ponds all leaned on each other. Nothing is ever just one cause — and nothing on your desk is just a thing.
➊ Luck is only worth what your rules make it worth. ➋ Boring rules — building codes, drills — save more lives than heroes do. ➌ Someone else's invention can end your best industry, so never depend on one thing. ➍ A problem and its answer often arrive in the same parcel (no rain = huge sun). ➎ You can own a resource nobody can dig up: the dark, dry sky. ➏ People can take their country back by counting. ➐ No single hero. A chain. Again.
EVERY COUNTRY HIDES A STORY.
Japan had nothing. America had everything. An island had a doorway. A continent had the ground. Nepal had height. Switzerland had empty mountains. A peninsula had only its people. A delta had no ground at all. A dry country kept its head. A green island called its children home. One sent its soldiers away. One changed a single rule and fed the world. One sold the machines that build the factories. One built itself out of code. One was given up on and did the fastest good in history. One found oil and saved almost all of it. And this one was a ribbon between a desert and the ice, and turned four odd pieces of luck into rules that hold. But every country in this book so far has had banks, branches, cashiers, queues — the plumbing of money, built over centuries out of stone and paper. So now the compass swings to East Africa, to a country of highlands, tea, rift valleys and long-distance runners, where most people in 2005 had no bank account at all and no branch within a day's walk. Instead of building thousands of banks, they put the whole economy onto the plainest mobile phone you have ever seen — and the rest of the world is still trying to catch up. What happens when a country skips a step everybody else thought was compulsory?
