WhkdfsElhHk 0:00–1:03 — A converted World War Two oil tanker called the Ideal-X sits low in the water, and something is wrong with the way she looks.
WhkdfsElhHk 1:05–2:09 — The dockworkers who watched her leave Newark did not know it yet, but they had just watched the beginning of the end of their entire trade.
WhkdfsElhHk 2:11–3:22 — Shanghai alone now moves something like forty-nine million of these boxes a year, more than any port on the planet, for fourteen years running.
WhkdfsElhHk 3:24–4:36 — A ship might spend as long tied up in port, loading and unloading, as it spent actually crossing the ocean.
WhkdfsElhHk 4:38–5:41 — Longshoremen were skilled workers, in the truest sense, artists of tight spaces and awkward weights, and their skill was exactly the problem.
WhkdfsElhHk 5:42–6:47 — And McLean, driving that business, kept running into the same maddening bottleneck, over and over: his trucks, loaded with cargo, would arrive at a port to have their freight shipp…
w1Loz8IG73I 0:00–1:16 — Precisely 5 minutes after the homeowner leaves for work in the morning, a package is gently delivered to their doorstep containing an impulse purchase from the night before.
w1Loz8IG73I 1:23–2:42 — This is particularly impressive since the permanent population of the outpost is actually less than a few hundred people.
w1Loz8IG73I 2:47–3:52 — shore without a dedicated deep water port, and those are expensive. The port only handles two particular products in bulk.
w1Loz8IG73I 3:58–5:08 — If you ever did an electrolysis experiment in science class, separating out hydrogen and oxygen, the process is almost the same.

字幕依据：Shanghai alone now moves something like forty-nine million of these boxes a year, more than any port on the planet, for fourteen years running. Singapore is close behind, at roughly thirty-nine million. Nine of the ten busiest container ports on earth are now in Asia. WhkdfsElhHk@2:11
字幕依据：A ship might spend as long tied up in port, loading and unloading, as it spent actually crossing the ocean. Every item that passed through a longshoreman's hands was an item that could be dropped, crushed, or simply walk off the dock in someone's pocket, a habit so common on the waterfront that workers had a name for it: the five-finger discount. WhkdfsElhHk@3:24
字幕依据：Longshoremen were skilled workers, in the truest sense, artists of tight spaces and awkward weights, and their skill was exactly the problem. Loading a ship well took judgment, took time, took a small army of specialized hands, and every one of those hands had to be paid whether the ship was earning money at sea or simply sitting, dead weight, tied to a pier. WhkdfsElhHk@4:38
字幕依据：And McLean, driving that business, kept running into the same maddening bottleneck, over and over: his trucks, loaded with cargo, would arrive at a port to have their freight shipped onward by sea, and then simply sit there, sometimes for days, while longshoremen unloaded them crate by crate, sack by sack, and hand-stacked the contents into a ship's hold. WhkdfsElhHk@5:42
字幕依据：Precisely 5 minutes after the homeowner leaves for work in the morning, a package is gently delivered to their doorstep containing an impulse purchase from the night before. This box is just one of 36 million that will be delivered across America over the next 10 hours, serving a growing appetite for home delivered consumption. w1Loz8IG73I@0:00
字幕依据：shore without a dedicated deep water port, and those are expensive. The port only handles two particular products in bulk. Ships take out raw aluminina and bring in heavy fuel oil, which is used in a self-contained electrical plant to power both the industrial mine site and the local township. w1Loz8IG73I@2:47
字幕依据：This industrial city center across the bay from Hong Kong and Shenzhen has become a trade hub for raw materials like copper, steel, and aluminium. Vendors like Henan Aluminium Industrial Company will buy these ingots directly from smelting plants and then ship them to their warehouses across the river. w1Loz8IG73I@5:13
字幕依据：parts that make the products you interact with every day. Once the beams are unloaded into the factory warehouse, they're loaded into grinding machines to etch out a basic spoke pattern, and then they're sliced lengthwise to produce hundreds of basic standardized gears. w1Loz8IG73I@6:36
