3
00:28:21,850 --> 00:28:25,620
We think that our blue cities will first just grow
4
00:28:25,620 --> 00:28:29,390
From beyond to the waterfront but still be part of our city,
5
00:28:29,390 --> 00:28:31,790
And maybe in the near future the first communities
6
00:28:31,790 --> 00:28:35,830
Will be created on the middle of the ocean.

It borrows technology from oil platforms.
12
00:28:53,920 --> 00:28:55,680
It's called the jack-up system.
13
00:28:55,680 --> 00:28:59,650
It's made of four hydraulic legs
14
00:28:15,310 --> 00:28:17,580
Narrator: The ultimate vision is the construction
15
00:29:02,860 --> 00:29:04,620
And touch the sea bottom,
16
00:29:04,630 --> 00:29:08,230
In our case up to 20, 25 feet of water.
17
00:29:08,230 --> 00:29:10,930
That enables us to completely stabilize the boat
18
00:29:10,930 --> 00:29:15,400
And even lift it out of the water.
19
00:29:15,400 --> 00:29:18,040
One of the most advanced features on this prototype
20
00:29:18,040 --> 00:29:19,940
Is it doesn't need to be towed.
21
00:29:19,940 --> 00:29:24,340
It can move under its own power.
22
00:29:24,350 --> 00:29:26,210
Derouin: They're completely solar electric,
23
00:29:26,210 --> 00:29:28,080
So the... (speaks indistinctly)
24
00:29:28,080 --> 00:29:31,120
Is equipped with two electric thrusters
25
00:29:31,120 --> 00:29:34,620
That allow it to move at speeds up to seven knots.
26
00:29:34,620 --> 00:29:37,490
It's completely sustainable and self-sustained,
27
00:27:36,000 --> 00:27:38,910
Gets hit by some of the most vicious hurricanes,
28
00:26:59,330 --> 00:27:02,300
And it seeps into our pipes.
29
00:27:02,300 --> 00:27:03,700
Narrator: Downtown fort lauderdale
30
00:27:03,710 --> 00:27:05,140
Would regularly flood
31
00:27:05,140 --> 00:27:07,170
If it weren't for these storm stations
32
00:27:07,180 --> 00:27:10,280
And another genius solution.
33
00:27:10,280 --> 00:27:15,620
The city has installed 162 of these one-way valves.
34
00:27:15,620 --> 00:27:17,750
We call them "tidal valves."
35
00:27:17,750 --> 00:27:22,020
And the idea is that while water cannot move in this direction --
36
00:27:22,020 --> 00:27:25,660
If I put my hand in I can't make it go anywhere,
37
00:27:25,660 --> 00:27:29,700
But if there's water from the sky it can then open up
38
00:27:29,700 --> 00:27:34,670
And allow the water out.
39
00:27:34,670 --> 00:27:36,000
Narrator: This part of the u.S.
40
00:29:37,490 --> 00:29:40,790
So it gives a lot of freedom
41
00:27:38,910 --> 00:27:43,180
Leaving architects to explore the idea of "aquatecture"
42
00:27:43,180 --> 00:27:46,750
Or floating buildings.
43
00:27:46,750 --> 00:27:50,820
Building underwater is one way to make the city
44
00:27:50,820 --> 00:27:56,490
More resilient for the future and to adapt to rising seas.
45
00:27:56,490 --> 00:27:58,790
So what we do, we call this aquatecture,
46
00:27:58,790 --> 00:28:03,130
And you can compare it with architecture on land
47
00:28:03,130 --> 00:28:05,670
But then with floating foundations.
48
00:28:05,670 --> 00:28:08,070
So the buildings, the look and feel --
49
00:28:08,070 --> 00:28:10,440
It's almost the same as the structures on land,
50
00:28:10,440 --> 00:28:12,770
But it has the ability to cope with climate change,
51
00:28:12,770 --> 00:28:15,310
Sea level rise, and with floods.
52
00:31:30,110 --> 00:31:32,110
To make sure that these kind of neighborhoods
53
00:31:03,510 --> 00:31:04,940
But we need these kind of clients.
54
00:31:04,950 --> 00:31:06,310
We need these kind of companies
55
00:31:06,310 --> 00:31:08,480
To bring this kind of engineering
56
00:31:08,480 --> 00:31:10,820
Because the innovation is being paid by the rich.
57
00:31:10,820 --> 00:31:13,750
But then we can bring it to more vulnerable
58
00:31:13,760 --> 00:31:15,260
And more poor countries.
59
00:31:15,260 --> 00:31:16,790
So, you see, for instance, in bangladesh
60
00:31:16,790 --> 00:31:19,560
Where there are so many slums around the water
61
00:31:19,560 --> 00:31:22,560
And they are being threatened by every sea level rise
62
00:31:22,560 --> 00:31:24,030
And every water rise.
63
00:31:24,030 --> 00:31:26,700
We can bring there very small floating schools,
64
00:31:26,700 --> 00:31:30,100
Floating hospitals, floating energy plants
65
00:31:00,210 --> 00:31:03,510
So it's not for everybody.
66
00:31:32,110 --> 00:31:33,510
Are being treated well
67

And being upgraded from the situation they're in now.

00:31:37,880 --> 00:31:39,810
Narrator: A passion for profit

May be driving innovation in florida.
70
00:31:42,580 --> 00:31:44,420
But in the waterlogged netherlands,
71
00:31:44,420 --> 00:31:47,650
There's another kind of passion at work.

Who love to live on the water.
75
00:32:01,140 --> 00:32:04,540

You can change your neighbors if you want.

They wouldn't need to get their water from underground.

That ground water comes through what is a very porous geology,

Is making life on the water more dangerous.

Water that sits in the spaces between the grains of sediment
412
00:06:41,990 --> 00:06:46,620
Provides enough pressure to hold up the ground above it.
413

When the ground water is removed
414

To be used for homes and factories,
415
00:06:50,930 --> 00:06:54,300
The sediment gradually compacts.
416
00:06:54,300 --> 00:06:57,230
That compaction causes the land's surface

And that subsidence becomes significant.
426
00:07:24,990 --> 00:07:26,860
Narrator: Part of the problem is that the rivers
427
00:07:26,860 --> 00:07:32,070
That used to feed the lagoon were diverted in the 1500s.
