depends on energy
00:01:41
today we will take you into a new field
00:01:44
to reveal how energy is driving the

the Gobi Desert in northwest China
00:02:17
a group of engineers are searching for
00:02:19
the enormous energy buried beneath the

desert sand yuan hood Zhang is a veteran
00:02:30
blasting engineer with 37 years of
00:02:32
experience
00:02:33
today he and his team will use 1418 tons
00:02:38
of explosives to blow to smithereens a
00:02:40
38 meter thick layer of rock in an area
00:02:43
the size of five football fields at the
00:02:46
same time they must make sure that what
00:02:48
goes up comes down in all the right
00:02:50
places
00:03:07
the charges cannot be set off
00:03:09
simultaneously which would result in

mr. Tom that approaches the wooby dog
00:03:20
it's cheaper - are you a teacher katana
00:03:24
activate we can further contain yogacara
00:03:28
the solution is to detonate the
00:03:31
explosives in batches
00:03:38
there are 781 blasting holes divided
00:03:42
into 12 groups each group will be
00:03:45
detonated less than one hundredth of a
00:03:47
second after the previous group to make
00:03:55
this work the blasting team needs
00:03:57
electronic detonators
00:04:09
with an encoder the operator can
00:04:11
accurately control the ignition of
00:04:13
thousands of electronic detonators in
00:04:15
milliseconds the blasting interval is
00:04:19
set to eight milliseconds the blast time
00:04:22
is set for just after 4:00 p.m. in the

[Music]
00:04:32
the Chinese have invested billions of
00:04:34
dollars to build facilities in this arid
00:04:36
inland area beside the desert to produce
00:04:39
this the coal found here is of superior
00:04:47
quality while having a very high heat
00:04:49
value it contains less sulfur and is
00:04:52
therefore less damaging to the
00:04:53
environment today coal is still the main
00:05:02
energy that drives more than half of
00:05:04
China's economy this is one of the
00:05:09
opencast mines operating in China the
00:05:14
coal is of quality and the seams are
00:05:15
very thick coal seams of over 15 meters
00:05:20
in thickness are regarded as super-high
00:05:22
seams across the world and the seams
00:05:24
here are up to 30 meters thick of course
00:05:32
in order to mine this precious coal the
00:05:34
upper layer of rock needs to be removed
00:05:48
funnier
00:05:54
before receiving the formal command of
00:05:56
detonation the blasting team has carried
00:05:58
out the final checks on their electronic
00:06:00
detonators through an encoder by 4:00
00:06:04
p.m. the billions of dollars worth of
00:06:06
equipment in the mining area have
00:06:08
already been moved to safety
00:06:25
[Music]
00:07:00
as usual UN as own to the blasting area

try this show quick no I didn't um yeah
00:07:20
20 sir
00:07:22
it seems yuan is quite satisfied with
00:07:24
the result of today's blasting
00:07:32
after removing the gravel a new coal
00:07:34
seam reveals itself half an hour later
00:07:37
the smoke is cleared then the mining

00:08:04
the daily output of coal from this
00:08:06
man-made Canyon is over 100,000 tons it
00:08:10
could generate enough power to supply
00:08:11
one modern family for 10,000 years
00:08:16
[Music]
00:08:21
but it's just one percent of the daily
00:08:24
output of China Cola is the primary
00:08:35
position in China's energy structure
00:08:39
because of that it is particularly
00:08:41
important to use coal efficiently one of
00:08:47
the most efficient ways is to build
00:08:48
large power plants near to the coal
00:08:50
fields this reduces transportation costs
00:08:53
and keeps pollution to the remote areas
00:08:55
far from the cities the West of China
00:08:59
has a substantial coal reserves but it
00:09:01
is very short of water and that is a big
00:09:03
issue when it comes to cooling these
00:09:05
power plants
00:09:22
done one long head of maintenance is
00:09:25
going to carry out a special project
00:09:26
today to build a thermal power plant in
00:09:39
a desert was impossible in the past
00:09:41
because a traditional thermal power
00:09:43
plant needs so much water for cooling
00:09:46
the boiler cannot operate without it
00:09:50
[Music]
00:10:03
however China has begun to build large
00:10:05
thermal power plants in the desert
00:10:07
because it has found a solution
00:10:16
the secret lies in these passive cooling
00:10:18
towers which do not use water as the hot
00:10:22
air rises from the top of the tower
00:10:24
cooler air is drawn in at its base over
00:10:27
an array of radiators
00:10:36
someone Long's job is to keep the
00:10:38
radiators clean he has to clean nearly 1
00:10:41
million square meters of radiators with
00:10:43
the least amount of water he can
00:10:45
[Music]
00:10:52
to achieve a better cooling effect the
00:10:55
132 radiators are distributed in a
00:10:57
v-shape
00:11:06
as this type of passive cooling tower is
00:11:10
not directly need large quantities of
00:11:12
water it is possible to build them in
00:11:14
the desert
00:11:15
[Music]
00:11:28
the East of China is home to just under
00:11:31
seventy percent of the country's
00:11:33
population and over 80 percent of its
00:11:35
economy however most of the new energy
00:11:39
resources are in the West thousands of
00:11:41
kilometers away the energy
00:11:45
transportation has been a problem for
00:11:47
the country for quite a long time
00:11:53
china plans to build more large power
00:11:55
plants around the coal fields of western
00:11:57
china convert coal into electricity and
00:12:00
then let the power grid carry it to the
00:12:02
east it is the largest energy
00:12:05
transmission project in human history
00:12:14
[Music]
00:12:17
today the project begins a new phase the
00:12:20
installation of the conductors at the
00:12:31
foot of pylon number 323 the linesman
00:12:34
are getting ready to join the conductors
00:12:36
high up in the air
00:12:45
[Music]
00:12:55
[Music]
00:13:03
this is the world's longest and highest
00:13:06
voltage power transmission line it
00:13:10
starts in the jungle basin in the Far
00:13:12
West of China and runs for three
00:13:14
thousand three hundred twenty four
00:13:16
kilometers across deserts mountains
00:13:18
canyons to the densely populated East in
00:13:28
eight years China has built more than
00:13:30
thirty thousand kilometres of
00:13:31
high-voltage lines to establish the
00:13:34
world's largest energy transmission
00:13:36
network
00:13:41
to increase the system's efficiency the
00:13:44
voltage needs to be raised
00:13:54
the 1.1 mega volt high-voltage line is
00:13:58
the highest in the world at present it
00:14:04
can transmit the energy generated by 80
00:14:07
thousand tons of coal over a distance of
00:14:09
three thousand kilometers in a day
00:14:14
to ensure the transmission runs smoothly
00:14:17
and efficiently the 20,000 conductor
00:14:20
joints have to be connected perfectly
00:14:30
the cables are connected by intense
00:14:32
pressure first the outer aluminum wires
00:14:36
are stripped back to expose the steel
00:14:38
core then the two ends of steel core are
00:14:49
inserted into a metal sleeve
00:15:03
a hydraulic clamp presses hard on the
00:15:06
sleeve to hold the two sections of steel
00:15:08
cable firmly together
00:15:16
after the steel core is joined a larger
00:15:19
sleeve is used to connect the outer
00:15:20
aluminum wires
00:15:28
the procedure seems simple enough but
00:15:30
it's quite another thing to do it 100
00:15:32
metres up in the air with everything
00:15:34
swaying in the breeze the workers need
00:15:40
to hold two ends of the cables carefully
00:15:42
and avoid damaging the conductor's while
00:15:45
dealing with the five tonne tensile drag
00:15:47
on the cable to manage this they must
00:15:53
use a special cable
00:16:25
combining the eyeball
00:16:43
the job not only requires concentration
00:16:46
but also a head for Heights
00:16:52
[Music]
00:16:56
it will take six months to complete the
00:16:59
new 3324 kilometer line and this is just
00:17:07
the beginning
00:17:08
several more are being planned to follow

early November a deep-sea engineering
00:17:25
vessel is anchored off the coast of
00:17:27
South China the sea is calm but captain
00:17:33
Jin region is not
00:17:38
he needs a storm and he has already been
00:17:41
waiting for three days
00:17:53
the new ship has been built at a cost of
00:17:56
two hundred million dollars the waters
00:18:01
around China are greatly affected by the
00:18:03
western Pacific ocean currents these
00:18:06
prevent divers from conducting deep-sea
00:18:09
seabed operations this ship has been
00:18:13
built to deal with that challenge thus
00:18:18
to test the new ship's ability to work
00:18:20
in rough sea conditions captain Jin's
00:18:23
crew must wait for some strong waves
00:18:29
historically it has been very difficult
00:18:31
for China to develop deep-sea oil and
00:18:33
natural gas resources hopefully this
00:18:36
will change if this new ship tests
00:18:38
successfully it depends on whether the
00:18:41
advanced equipment on board function is
00:18:43
intended the expected wind and waves do
00:18:49
not arrive captain jian has to look for
00:18:52
another storm
00:18:59
and the teacher kind of thinking that
00:19:03
mean
00:19:04
only the worst Dow new latest weather
00:19:15
forecast leads the captain in the
00:19:16
Navigator to choose a new test area
00:19:19
[Music]
00:19:34
after a night sailing the ship reaches
00:19:36
its destination as the sea gets up the
00:19:42
test commences
00:19:48
the key requirement for accurate
00:19:51
underwater operations is that the
00:19:53
equipment is stable even ooh verd in
00:19:59
order to achieve this the engineering
00:20:00
ship has to remain in a fixed
00:20:02
geographical position against the
00:20:04
flowing currents and heavy seas this is
00:20:11
done by the approach power compensator
00:20:13
system when waves drive the ship off
00:20:19
position the compensator system
00:20:21
instantly starts the corresponding
00:20:23
thruster to offset the force of the sea
00:20:26
this keeps the ship in a steady position
00:20:33
however when the ship rolls or is lifted
00:20:36
by the waves the thrusters alone are not
00:20:38
sufficient
00:20:47
but this new ship has another piece of
00:20:49
special equipment the world's largest
00:20:52
crane with an automatic height
00:20:53
compensation system
00:21:06
[Music]
00:21:09
the high power crane is able to lift up
00:21:12
to 400 tons
00:21:19
as the ship rises and falls in the swell
00:21:21
the crane automatically detects the
00:21:23
speed and direction of the movement it
00:21:28
then reacts instantly to compensate for
00:21:30
this by retracting or paying out its
00:21:32
cable lines or by turning its lifting
00:21:35
arm
00:21:43
oh my gosh oh yeah
00:21:50
all right you take a poncho y'all bad
00:21:51
will go to make full use of this right
00:21:56
see conditions the test must continue

the sea floor
00:24:26
fire ice also called combustible ice is
00:24:30
a common name for methane hydrate it
00:24:34
exists as a flammable solid in which
00:24:36
methane is trapped in a crystal
00:24:37
structure of water originally it was
00:24:42
assumed only to exist in the outer
00:24:44
reaches of space but it has been found
00:24:46
to exist in extraordinary quantities on
00:24:48
earth below the seabed it forms the
00:24:52
largest reserve of fossil fuel on the

00:24:54
however extracting it is no simple
00:24:57
matter to date reliable mining
00:25:00
techniques have yet to be developed a

previous mining test only lasted for 12
00:25:07

00:28:03
are planning to cast a seamless concrete
00:28:06
dam across the world concrete fracture
00:28:09
is a recognized technical bottleneck the
00:28:13
larger the project the more serious the
00:28:15
problem there's an engineer saying that
00:28:19
every Dam has fractures
00:28:25
it will take 2.91 million cubic meters
00:28:28
of concrete to cast the wudong Dam the
00:28:33
plan calls for a wall 275 meters high
00:28:37
and between 12 and 51 meters thick
00:28:40
[Music]
00:28:43
to withstand the pressure from up to 270
00:28:47
meters depth of water the dam cannot
00:28:49
have even the slightest fracture the key
00:28:52
to building a seamless dam lies in the
00:28:55
continuous control system the casting
00:28:57
process has to go on continuously for 33
00:29:00
months without interruption Jung must
00:29:03
find a way to avoid the operation being
00:29:05
blighted by rain as soon as possible
00:29:13
young faces a dilemma if they cast in
00:29:17
the rain the rain could alter the
00:29:19
composition of concrete
00:29:24
if the casting stops the concrete
00:29:27
components cast before and after the
00:29:29
rain will not marry properly
00:29:40
to work through the rain or wait for it
00:29:43
to clear up a decision has to be made
00:29:53
lorraine is forecast to have cleared the
00:29:56
area by the 29th youngling decides to
00:30:02
start the operation as soon as it stops
00:30:06
by 8:00 in the morning the wet weather
00:30:09
has passed 30 minutes later the

temperature controlled concrete arrives
00:30:21
on site
00:30:37
well Monsanto goshawk change in saying
00:30:40
you change or to be poor
00:30:42
- that's haunted shares a bottle
00:30:51
woman who knew the heat generated as the
00:30:57
concrete sets is the main cause of
00:30:59
cracking as the concrete has almost no
00:31:06
malleability and the internal and
00:31:08
external cooling speeds are different
00:31:10
this uneven thermal distribution is what
00:31:13
can lead to cracks
00:31:18
to build a seamless dam the key is to
00:31:21
achieve precise temperature control
00:31:23
during the continuous casting process
00:31:35
Jung has made a timely decision and has
00:31:37
successfully avoided the bad weather
00:31:53
when the plant is completed the mighty
00:31:56
river waters will be harnessed to the
00:31:58
grid however rich water resources are
00:32:02
not found everywhere
00:32:13
the town of dulling ha in the west of
00:32:15
China is short of water but has plenty
00:32:18
of sunshine
00:32:23
the power of the sunlight and the number
00:32:25
of hours the Sun shines makes it an
00:32:27
ideal site for solar arrays
00:32:35
the maintenance engineers have to get to
00:32:37
work early in the day the key components
00:32:57
of the array are these mirrors
00:33:04
when Sun rises over the Gobi Desert at
00:33:07
7:00 in the morning more than 20
00:33:09
thousand mirrors bounce the light with
00:33:10
great precision to the top of a tower
00:33:19
the heat generated there is absorbed by
00:33:22
molten salt which takes the heat down
00:33:24
into the plant where water is heated
00:33:26
into steam which drives the turbines to
00:33:28
generate electricity
00:33:36
this way of generating electricity does
00:33:38
not consume any fuel or discharged any
00:33:40
emissions it is an ideal way of
00:33:43
utilizing solar energy there is one
00:33:49
catch though the Sun keeps changing its
00:33:53
position if the alignment of the mirrors
00:33:57
is slightly off there will not be enough
00:33:59
energy to heat the salt atop the tower
00:34:01
sufficiently to solve this problem China
00:34:10
has developed a precise sunlight
00:34:11
tracking system for this tower type of
00:34:14
photo thermal power plant controlled by
00:34:17
a computer the 20,000 mirrors reflect
00:34:19
the sunlight to the top of the tower
00:34:21
when the nearing accuracy
00:34:29
the conditions of the region lend
00:34:31
themselves to solar power general but
00:34:34
there's more than one ways to turn rays
00:34:36
into vaults not far away another solar
00:34:42
power plant ten times of its size is
00:34:44
under construction it is a trough type
00:34:49
photothermal power plant
00:34:56
unlike the tower type power plant it
00:34:59
collects the heat of sunlight through
00:35:00
curved mirrors
00:35:01
[Music]
00:35:08
however both systems rely on precise
00:35:11
solar tracking therefore quality control
00:35:18
manager gülen's wit monitors the
00:35:20
installation of every trough
00:35:21
concentrator
00:35:24
a trough concentrator is made up of
00:35:29
perfectly curved mirrors they track the
00:35:32
Sun under the control of computer if a
00:35:38
parabolic solar trough is not smooth the
00:35:40
reflected light will not be accurately
00:35:42
focused the installation must again be
00:35:45
done to very precise tolerances so what
00:35:55
is happen in Hawaii hum the area of each
00:36:01
parabolic trough is 69 square meters
00:36:07
[Music]
00:36:09
after installation is completed the
00:36:12
mirrors will be aligned to within less
00:36:14
than one millimeter this plant will have
00:36:25
9120 solar troughs generating 50,000
00:36:29
kilowatts per hour
00:36:36
China's currently installed solar power
00:36:38
capacity exceeds 70 million kilowatts
00:36:41
accounting for one-fifth of the world's
00:36:43
solar generation capacity more and more
00:36:46
ways to utilize solar energy will
00:36:48
revolutionize China's supply of clean
00:36:50
energy it's rapid development shows
00:36:56
China's genuine determination to change
00:36:58
its energy structure
00:37:06
but there are other emission-free energy
00:37:09
sources to be tapped into China is one
00:37:12
of the nations that have taken the lead
00:37:14
in seeking renewable energy from the
00:37:16
wind giant turbines are a common feature
00:37:19
of the landscape in many locations wind
00:37:25
energy is often harvested more reliably
00:37:27
at sea but the harsh environment has
00:37:29
posed serious challenges to the
00:37:31
installation and maintenance of the
00:37:33
turbines
00:37:42
previously when turbine generators were
00:37:45
assembled on land and then ferried to
00:37:47
their operating sites by semi
00:37:49
submersible vessels for final erection
00:37:51
the process was costly slow and resource
00:37:55
intensive
00:38:03
today offshore wind is looking more and
00:38:06
more like the future of wind power
00:38:11
breakthroughs and installation
00:38:13
technology will greatly reduce the cost
00:38:17
on the eastern coast of China one of
00:38:21
these new installation methods is still
00:38:23
being trialed to ensure tomorrow's trial
00:38:30
runs smoothly Operations Director is
00:38:33
working late checking all the
00:38:55
the new method depends on this newly
00:38:57
developed tool it can accurately set the
00:39:04
angle of a blade at a height of nearly
00:39:05
100 meters so that it is perfectly
00:39:08
aligned to the rotor hub
00:39:16
if the machine works as it should the
00:39:19
cost of installing offshore wind
00:39:21
turbines will have by 11:00 at night the
00:39:30
engineers have finished tweaking their
00:39:32
setup the following day the crucial test
00:39:41
will begin at 7:00 in the morning
00:39:47
Oh Toronto Toronto rental idea
00:39:58
two hours later a 50 meter long 20 ton
00:40:02
blade is lifted to the hub
00:40:12
now comes the tricky part
00:40:21
the crew needs to marry the blades
00:40:23
fastening bolts to the rotor hub 100
00:40:26
meter up in the air where the slightest
00:40:28
breeze can push everything out of
00:40:29
alignment
00:40:37
this is when the new clamping system
00:40:39
comes into its own it allows the
00:40:44
operator precise control over the blades
00:40:46
position and connected to the hub with
00:40:49
pinpoint accuracy
00:40:55
naughty naughty
00:40:57
three hours later the rotor blade is
00:41:00
successfully installed
00:41:07
this new method of installation will
00:41:10
dramatically reduce installation costs
00:41:12
and put new wind in the sails of the
00:41:15
offshore power generation industry in
00:41:22
China the progress of science and
00:41:24
technology drives energy development and
00:41:27
a mixed source energy policy is the

00:41:38
be put into operation the nuclear
00:41:42
reaction releases enormous heat this is
00:41:49
used to turn water into high-pressure
00:41:51
steam which drives the generators to
00:41:53
generate electricity
00:42:01
the core of a nuclear power plant is the
00:42:03
reactor unit this nuclear power unit is
00:42:09
built to the world's highest safety
00:42:11
standards before it starts operations
00:42:14
many and repeated safety inspections
00:42:17
have to be completed
00:42:25
the engineers test a three-story high
00:42:28
safety door it is made of special metals
00:42:31
and manufactured with aerospace
00:42:33
technologies like the safety door nearly
00:42:41

nuclear fusion with none of this
00:46:05
radioactive waste scientists have long
00:46:08
dreamed of being able to emulate this on
00:46:13
July 5th 2017 Chinese scientists
00:46:17
released a 100 seconds of video which
00:46:19
amazed the world's scientific community
00:46:23
the video shows an experiment in which
00:46:26
Chinese researchers managed to achieve a
00:46:28
temperature of 50 million degrees
00:46:30
sufficient to overcome the barriers to
00:46:32
fusion reaction but no known material on
00:46:41
the earth can handle even one ten
00:46:42
thousandth of such a temperature what
00:46:47
kind of vessel could contain such a high
00:46:49
temperature reaction the answer is a
00:46:53
magnetic field
00:46:59
the coil enters a superconducting state
00:47:02
at low temperatures producing the
00:47:04
strongest magnetic field on the earth in
00:47:08
this can float the materials for a
