00:00At the heart of the wild and wild mountains, we built something massive, so huge that it could shine from
00:06space.
00:08So, we should call it the New Grande Muraille of Chine.
00:11If the ancient muraille falls on thousands of kilometers,
00:15this bridge concentrates all the resources in one single block rocker of more than 335 meters high.
00:21In this moment, thousands of workers and giant machines build one of the most crazy projects of the planet,
00:27the barrage of Rogoun.
00:29Some questions have been asked.
00:31Why?
00:32Why to do it?
00:33And for how much?
00:35And above all, with the floods of land who constantly arrive,
00:38is it really going to happen?
00:40Or is it just a phantasm to several billions of dollars waiting to fall?
00:44To have a view of an ensemble, we need to understand the wild landscape of Tajikistan.
00:49We are not at all on the agricultural land.
00:51Around 90% of the country is covered by wild mountains and déchiquetées.
00:55It's one of the most mountainous countries in the world.
00:58These sommets are covered by sea glaciers and lourdes calottes of snow all the year.
01:03But these beautiful mountains cachent a gigantic power, redoubtable power.
01:08Every springtime and every summer, when the sun ends at point the bottom of its nez,
01:12all this snow and this glace begin to fall at a crazy pace.
01:15The water is going to fall on the mountains,
01:18taking a speed and a incredible force to become the powerful Vaxch.
01:23It's millions of liters of glass and water glaciers,
01:26falling through deep valleys.
01:29Since generations, this massive volume of water is controlled
01:31represents a terrifying problem for the inhabitants.
01:34Without anything to slow down,
01:36the river déchaînée caused an inondation seasonally devastating.
01:40And we don't talk about some floods by there.
01:43The bad years, these murs d'eau and de boue
01:45had destroyed hundreds of thousands of villages in a few hours.
01:50Thousands of people were displaced
01:51and the deaths were counted in tens of millions of dollars.
01:55It was a force of the wild and indomptive nature
01:57who had desperately needed an enormous pan-stop
02:00or to be put in the air.
02:03It can surprise me,
02:05but the river of Rogoun is not a new idea.
02:07In fact, the dream of building a mega-barrage
02:10to this precise place exists for decades.
02:14The construction started very long,
02:16but because of an instability severe
02:18and of a sudden loss of funding,
02:21the huge project had to be completely abandoned.
02:26It remained there for years,
02:27a dream inachevé,
02:28taking the dirt and bad herbs in the mountains.
02:32At the beginning of the 1990s,
02:34the situation had gone from bad to catastrophic
02:36and not only because of the meteor.
02:39At a moment, the region was struck by extreme poverty
02:42and the political situation was very unstable.
02:45Between 1992 and 1997,
02:48a large number of people had gone by the country,
02:50afraid of their lives because of confies locaux.
02:55This was not only a social and economic chaos.
02:57A violent and inondation and inattend
02:59a felled in the valley,
03:00destroying the first buildings of construction.
03:03The eau déchaînée has practically
03:05effaced the years of dur labor
03:07in a clin d'œil.
03:08Most people would have simply
03:10plied the baggage
03:11and abandoned the land.
03:12But the inhabitants of Tajikistan,
03:14obstinate and resilient,
03:16have simply refused to forget
03:17the village of Rogoun.
03:20After decades of economic struggles,
03:22the country finally managed to
03:24take the work of continually.
03:27But every mega-project
03:28creates a huge number
03:29and here it is the same.
03:31It was not just a national triumph.
03:35To fill a large reserve,
03:37the entire valley
03:38had to be inundated.
03:39Which means to force
03:41up to 60 000 people
03:43to quit their foyer.
03:44The experts
03:45also inquiètent
03:45the risks environmental
03:46for the provision
03:47in eau of the region.
03:49But the Tajik
03:50did not simply
03:50have wanted to leave the affair.
03:52The barrage
03:53is growing,
03:53but the facture
03:54could be afraid.
03:56Let's talk about
03:57numbers now,
03:57because the size
03:58of this thing is difficult
03:59to conceive.
04:01Once finished,
04:02the barrage
04:03of Rogoun
04:03will reach a record
04:04of about 335 meters.
04:07You need
04:07a more talk?
04:09If we took
04:10the Eiffel
04:10and placed it next to this barrage,
04:12the barrage
04:13would still surpass it.
04:15Once finished,
04:16he will gladly
04:17the title
04:18of the highest
04:19of the planet.
04:20This extreme
04:21is absolutely necessary.
04:24The specific
04:24the barrage
04:25where the barrage
04:25is built
04:26is incredibly deep
04:27and deep
04:28in shape of a giant V.
04:31For creating
04:32a large reserve
04:32to contain
04:33hundreds of thousands
04:34of meters
04:35of water,
04:35the barrage
04:36has no other choice
04:38that to be
04:38very high
04:39in the sky.
04:40During the months
04:41of the winter,
04:42it will act like
04:43a giant
04:43of the sea
04:43of the sea
04:45and completely
04:47the dangerous
04:48of the sea.
04:49But
04:50there is another
04:51crucial reason
04:51to this
04:52high altitude.
04:53In Tadjikistan,
04:54the rivers
04:54are glaciers.
04:57The river
04:58is completely
04:58and the country
04:59has suffered厚ice.
05:02Not really
05:03the best way
05:04to pass
05:04the river.
05:05In construisant
05:06the barrage
05:06too high,
05:08they can stock
05:08an artificial
05:09massive
05:10of water
05:10during the summer,
05:11then relaxes
05:12slowly
05:13to turn the turbines
05:15in continue.
05:16But wait,
05:17it's not so simple.
05:19The barrage
05:20of Rogoon
05:20is one of the most
05:23dangerous zones
05:23in the planet.
05:25It means
05:25of the sea.
05:26that of the sea
05:26are a very real
05:29and frequent threat.
05:30If the engineers
05:31had simply
05:32a giant giant
05:33of rigid stone
05:34a sea
05:35could easily
05:36easily
05:36imagine
05:37take a biscuit
05:38and try to
05:39plier.
05:40It's immediately
05:41how to build
05:43the high altitude
05:44of the world
05:45in the middle zone
05:46of the sea?
05:46To solve this
05:48of the sea,
05:49the engineers
05:49have opted
05:50for what we call
05:51a barrage
05:51in remblay.
05:52In place
05:53of the sea,
05:54they build
05:55essentially
05:55an artificial mountain
05:56with millions
05:58of tons
05:58of rock compact
05:59of gravier
06:00and earth.
06:02The number
06:03of big boats
06:03that work on this
06:05day and night
06:06is just
06:07enormous.
06:08But the real
06:08magic of the engineering
06:09is happening
06:10in the center.
06:11Caché
06:12at the core
06:12of this mountain
06:13of rock,
06:14there is a special
06:15incredibly heavy
06:16made of steel.
06:18Why?
06:19You remember
06:20you can change
06:22the shape
06:23without
06:23breaking
06:24the same way.
06:27Because
06:27the steel
06:27is very compacted
06:28and naturally
06:29impermable
06:30and very flexible,
06:31this structure
06:31acts exactly like
06:33a gigantic
06:33amortisseur.
06:34When a
06:35tremblement
06:35of earth
06:35hits,
06:37the bridge
06:38doesn't
06:38fall.
06:39The rocks
06:40move
06:40slightly
06:40the
06:41rock
06:41and the
06:42is
06:42the
06:43and the
06:43rock
06:44is
06:44a
06:45rock
06:57and the
06:58rock
07:09is
07:11The answer is yes!
07:13When it will be fully operational, the bridge of Rogoun will be a real central power.
07:19At the heart of the roche mountain, the workers install meticulously six massive turbines.
07:24When the stocking of the eau will grow up through them, they will produce 3600 MW of electricity.
07:31It is enough of a clean and renewable energy to completely change the destiny of a nation,
07:36because this country is facing a very clear contrast.
07:39If some cities of Duchambé, the capital, are impressive,
07:43with their big modern buildings brilliantly clear and their current non-stop,
07:47the situation in the reculages of mountains is very different.
07:52For the inhabitants of the Tadjikistan rural,
07:54this mega-barrage means the end of these winter courants exasperates,
07:58where families must still have to count on clouds and heavy coverings just to survive the cold.
08:04But the advantages do not stop there.
08:07The bridge will produce so much energy that the Tadjikistan will not be able to use everything.
08:12They will have a massive massive surplus of energy propres,
08:15which means to export electricity and create a very new source of national revenue.
08:20We can talk about a real turn.
08:22It will bring, without effort, new jobs passionately,
08:25better infrastructures and a huge boost for the future of all the country.
08:30Now, you know that the village of Rogoun is much more than a simple tas of stones
08:34which block a river.
08:36D'ici the end of the work,
08:37the workers will have replaced more than 75 millions of m3 of terre and pierre,
08:43what remplir about 30 great pyramids of Gizeh.
08:46The project is so massive,
08:48that we can really see the journey from space.
08:51See you next time!
08:51you
