Wouldn't it be cheaper and better for the environment to buy some land off Germany or Sweden? Once the deal is sealed, they could start building the city the very next day.

There is plenty of space in Denmark for its existing population (and for millions more, for that sake). The issue is that there is not that much space in Copenhagen.

I don't really understand why expansion towards West is not an option.

Someone born in the late 1990s might expect to retire around 2070. Given the population structure in wealthy countries, early retirement at 65 is no longer feasible for most people in the younger generations.

Calling 65 years old early retirement is insulting...

Not sure if joking but that’s generally the age where pension kicks in/an individual can start pulling from tax advantaged retirement accounts.

A square mile is pretty big, especially for an artificial island. It’s 640 acres (or something like 2,400 suburban homes). Sure it’s not the size of Japan or something, but it’s not tiny.

The Dutch artificial island 'Flevopolder' is ~970 square km. So, I wouldn't say giant when there is an artificial island that has a 373x larger surface area. https://en.wikipedia.org/wiki/Flevopolder It is still a very nice project nonetheless!

But that’s a polder made mostly by building dykes and draining the land rather than raising up the ground level across 970 square km. Flevopolder is about 4m below sea level.

I think the plan here is different and will not be done by building up dykes and draining the area inside.

> The approval by Denmark's parliament paves the way for the 1 sq mile (2.6 sq km) project to begin later this year. That's not a giant island.

These kind of numbers are not intuitive. Don't forget that you are working in volume of material. Making something only 1m high across 1 sq mile is around 2.5 million cubic metres.

This is some remarkably long-term planning: "If construction goes ahead as planned, the majority of the foundations for the island off Denmark's capital should be in place by 2035, with an aim to fully complete the project by 2070." I can't recall ever seeing the year 2070 or later in print, in the context of some definite project or plan. Are there other examples?

Seems reasonable. Maasvlakte is a comparable project: an artificial island (20 km2 while this island is "only" 2.8km2) outside Rotterdam harbor and it was built over 25 years (1974-1997) https://en.wikipedia.org/wiki/Maasvlakte (Dutch wiki has much more info: https://nl.wikipedia.org/wiki/Maasvlakte ) Another comparable project is the new Strandeiland in Amsterdam https://www.amsterdam.nl/projecten/ijburg/deelproject…

China buit several artificial islands in just a few years - and not near shores (but some on reefs).

It can be done faster if enough resources are allocated... Denmark doesn't seem to be in a hurry.

Closest I can think of is the Chuo Maglev in Japan, approved in 2011 with a completion target of 2045. https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen

Japan also has many artificial islands, I wonder how long some of those projects took.

Most of those are a continuous project. The islands are the ultimate destination for incinerator ash and large garbage. The occasional tunneling project will dump the dirt etc.

You can see from goog maps how there are a couple outline online islands under "construction" and once those are filled they'll outline more.

In the US you can start pulling from retirement accounts in your 40’s as long as it’s even distributions for the rest of your life.

It will be good to see how many Y2038 issues they run into over such a duration and certainly be a good project that will touch upon that issue more than most due to planning dates.

Y2038 issue for those that don't know https://en.wikipedia.org/wiki/Year_2038_problem

My most favorite fact about Strandeiland is how it looks on google maps plan view. Apparently google already extracted streets from the satellite imagery, but didn’t yet updated the shape of island itself. So you see streets on IJ surface. https://goo.gl/maps/wrL42MHhBvPf1Ben9

Oh and of course in this country cycling paths are built before any houses.
