I run across this article yesterday. I enjoyed reading it. Plenty of interesting info. And this guy sure knows how to write a catchy first sentence in an essay!!
Ever wondered what kind of ships transport goods from one side of the world to the other?
https://www.economist.com/blogs/banyan/2 ... balisationSo almost everything about the Eleonora, which was built in the mid-2000s, is quite simply—The Biggest in the World, Ever. It is not just the biggest kind of container ship, but the biggest ship of any sort in service. To move its load through the water, it boasts the largest combustion engine ever built—generating horse power equivalent to 1,000 family-sized cars. The 14-cylinder engine turns the longest propeller shaft (130 metres) ever built, at the end of which is the largest propeller, weighing in at 130 tonnes. Yet so efficient is the engine, says the Danish chief engineer, that cruising at an average of 17 knots the ship consumes just 3 grams of fuel per tonne per nautical mile—which certainly sounds low. This sort of calculation, above all, makes a sophisticated laptop or iPad made in China affordable in Copenhagen.
This is “economy of scale” made steel…and the reason why the retailer Primark will be able to sell me a Chinese-made T-shirt for just a pound or two on my local high-street in Britain, just inside a month.
