This is New Albion on Mars
00:36
Everything is underground at New Albion!

For colonists, "underground" usually
refers to what's below their feet.

The ground level of Compartments is in fact
a deck over vital services running below.
00:54
Electricity and data cables, water, sewerage
and air-conditioning ducts run below the deck.
01:04
Electricity and data cables are
01:07
gas-tight, the others need their own
seals for depressurisation emergencies.
01:14
In minor emergencies the main ducts
can operate in a pass-through mode
01:19
with just local services sealed off.
01:23
In more severe emergencies a Compartment's
ducts can be completely sealed off.
01:30
This causes adjacent Compartments to
become effectively parts of separate Ways,
01:36
with services being pumped back and
forth rather than flowing through.
01:43
Some commercial utility equipment
is located below-deck -
01:47
laundry is commonly sited
next to mains services.
01:52
There are also storage lockers
01:55
which some colonists call 'garages' or
'sheds' and decorate accordingly.

'Going underground' at New Albion isn't
that different to being on top!
