It's relatively easy to construct underground, and it does not require
building
a foundation. Exit from the underground habitats may also be quite simple
via elevators, that pop up right in the middle of woods, that could work as
parks.
As far as I am aware of, the world doesn't have a single
city without
overground buildings. Just because standard cities are boring.

I'm not sure it's *that* easy to construct underground.
Assuming most of your depth is bedrock, it will need some
serious excavation work. Might be simpler to build above
ground and then infill/overfill with soil to turn your city into a
hill. |
|
| |
I'm with [Max] on this one, with a small adjustment,
excavate the topsoil (leave it in a handy pile nearby) build
then cover over & plant is probably the easiest way to go
about it. |
|
| |

My brother used to be a council building inspector with
trees as part of his remit (hence my awareness of the
following), tree root systems can be pretty extensive &
depending on the tree can do substantial damage to
structures they're planted too close too. |
|
| |
So if your only 'opencast' building & want woodlands above
you're probably going to have to leave unbuilt in
underground strips or avenues to allow for their roots. |
|
| |
Rule of thumb: For most species you need to go deeper
than the tree species height before you don't need to worry
about the roots, for width mirror it's branches. |
|
| |
But
for some species
it can be a lot deeper & wider. |
|
| |
Can I suggest a selection of fruit trees to attract Eloi & keep
them well fed & happy, always a good idea to keep your herds
close. |
|
| |
Is still above ground, just with a more viscous 'atmosphere',
not
the same thing at all. |

Hiroshima, 6 August 1945 ? |
|
| |
No, little boy wasn't that good, not at ground zero anyway
[linky]. |
|
| |
It wasn't bad for a first attempt, though. |
|
| |
Maybe time to try again ... |
|
| |
Hmm, there was a recent study by a bloke on
where did Hiroshima city go...unlike Nagasaki
Hiroshima is surround by hills. So when the
bomb was dropped it literally melted the city
into drops of glass and the city is in the beach,
on the hills etc. Nagasaki got off lightly
because the shockwave could expand. |
|
| |
We think you may have got those two the wrong way round; Hiroshima (the name translates as "Reed-island Castle") is on a flat area of river delta (hence the existence of the Aioi bridge) and Nagasaki is in a valley, which contained and deflected the blast. |
|
| |
You may find it helpful to consult the USAAF SBS after-action reports and the post-war investigation committee documents. |
|
| |
Given that Little Boy was only about 25kt point-zero yield, and was an airburst, the incident energy wouldn't be enough to "vapourize" structures as you imply, although there would be an immense amount of superficial heating and damage near the hypocentre; the majorty of the destruction was caused by the blast wave, and the bulk of the subsequent debris transport by the numerous secondary fires and consequent convection. |
|
| |
Not sure if the bombarded cities wold qualify. |
|
| |
Did Hiroshima / Nagasaki have an underground city before the
bombardment? Did these cities lose all the overground buildings as a
result of bombardment, leaving only the underground part livable? |
|
| |
Now you're changing the rules ... |
|
| |
And besides, "underground" cities do need foundations - in fact, they're pretty much all foundations. |
|
| |
Are you proposing a Moloch-like existance for the residents ? |
|
| |
Both Hiroshima and Nagasaki had some hardened below-ground structures before the bombings, but nothing particularly extensive; military command posts, air raud shelters, and a couple of telephone exchanges. But nothing extensive, like an underground rail system for example. |
|

Hmmm ... Caananite God of Fire, to whom children were sacrificed (allegedly), vs. H. G. Wells' troglodytic monsters ... |
|
| |
The second was intended, but thanks to the unsolicited intervention of the inline spellchecker, the former appeared. |
|
| |
Both are not without merit; a revision of the annotation is being considered. |
|
| |
Oh noes. Sudden realization -- this concept has been baked in some of
the science fiction, like
the movie Stargate's series. So, the idea totally not new, but, not baked in
real life. |
|
| |
In the movie The Shape Of Things To Come, your planet is shown towards the end as having been superficially restored to a "parkland" state, with all the industry still present, but underground. |
|
| |
//Both are not without merit/// |
|
| |
God like power & being worshipped or living underground &
feasting on the flesh of people.. |
|
| |
I think the former holds more
attraction for me, though I think my first devine
proclamation
is going to have to be to stop wasting potential future
resources by sacrificing them to me, they can keep
sacrificing
the infidels though, but only the adults, the children have
potential for conversion. |
|
| |
In real life there's Coober Pedy, which is a small opal mining
town in Australia. People there often live in caves dug into
hills to escape the heat. |
|
| |
Actually, they're trying to escape being in Australia. Digging escape tunnels makes perfect sense. |
|
| |
//Actually, they're trying to escape being in Australia.

|
| |
Yeah. Similarly, the bunker in Burlington was the
government trying to escape Britain, and the Catacombs of
Paris is the dead trying to escape France. |
|
| |
Of course ... paris is so horrible even the dead try to flee ... |
|
| |
As per normal, I am probably partially right - see What happened, physically, to the city of Hiroshima".linky - it is a most erudite study I have seen in quite a while. |
|

// Hobbiton New Zealand // |
|
| |
Cute! But are those miniature houses hobitable? |
|
| |
Sure. The insides are bigger than the outsides like the Tardis, but then the structures are dwarfed by an extensive interconnected subsurface mining operation. |
|
| |
// it is a most erudite study // |
|
| |
It is indeed; we are currently analysing it. |
|
| |
The science is very good, and the data is copious and well-presented. However, we may have grounds to dispute some of the conclusions, based on the hydrodynamics of the device and the way material is inducted into the "stalk" by convection as the cloud rises, plus the rate of cooling of the cloud - which is surprisingly rapid as the components of the device disperse. |
|
| |
Dammit, do we have to nuke Hiroshima again? |
|
| |
To validate the protocol, it should really be executed three times to demonstrate consistency and repeatability. |

A transparent observation window onto an oil/gas field?. |
|
| |
Just make sure your sleeping quarters aren't too close to the expansion/ resource processing sector. |
