China’s Mega Projects: Energy

What powers our vehicles and heats our rooms and our cold winters What keeps huge factories running incessantly at high speeds It all depends on

energy

Today we will take it to a new field to reveal how

energy

is driving the rapid development of the economy of China and the Challenges that must be overcome to keep the country's wheels turning under the pressure of the ever-increasing need for environmental protection. The Gobi Desert in northwest China. A group of engineers is searching for the enormous energy buried under the desert sand. Zhang is a veteran. blasting engineer with 37 years of experience today he and his team will use 1418 tons of explosives to blow up a 38 meter thick layer of rock in an area the size of five football fields at the same time they must make sure that what Rises Falls in all the right places The charges cannot be activated simultaneously, which would result in destructive seismic sr waves.

Tom, let him approach the wooby dog, it's cheaper: are you a teacher? Activate katana, we can contain even more yogacara. The solution is to detonate the explosives in batches. There are 781 blast holes divided into 12 groups. Each cluster will detonate in less than a hundredth of a second. After the previous group, for this job to work, the blasting team needs electronic detonators with an encoder. The operator can precisely control the ignition of thousands of electronic detonators in milliseconds. The blasting interval is set to eight milliseconds. The blast time is set just after 4:00. p.m. In the afternoon, the Chinese have invested billions of dollars to build facilities in this arid inland area next to the desert to produce this.

The coal found here is of superior quality and has a very high calorific value, contains less sulfur and is therefore less harmful to the environment. Environment Today coal remains the main energy powering more than half of China's economy. This is one of the open pit mines operating in China. The charcoal is quality and the veins are very thick. Coal seams more than 15 meters thick are considered super high seams around the world and the seams here are up to 30 meters thick, of course, to extract this precious coal, it is necessary to remove the top layer of rock before After receiving the formal order to detonate, the blasting team has carried out the final checks. into their electronic detonators via an encoder at 4:00 p.m.

Equipment worth billions of dollars in the mining area has already been moved to a safe place, as usual, the UN as its own to the blasting area to verify the results. Try this program quickly, no I didn't, yes 20 sir, it seems that Yuan is quite satisfied. With the result of today's blasting, after removing the gravel, a new coal seam is revealed half an hour later, the smoke dissipates, and then mining operations resume. The daily coal production of this artificial canyon is more than 100,000 tons and could generate enough energy to supply a modern family for 10,000 years, but it is only one percent of China's daily production.

Cola is the leading position in the China's energy structure, so it is particularly important to use coal efficiently. One of the most efficient ways is to build large power plants. near coal fields, this reduces transportation costs and keeps pollution in remote areas away from cities. Western China has significant coal reserves, but it has very little water and that is a big problem when it comes to cooling these power plants. fact a long maintenance manager is going to carry out a special project today to build a thermal power plant in a desert was impossible in the past because a traditional thermal power plant needs so much water to cool the boiler that it cannot function without it, however, China has started building large thermal power plants in the desert because it has found a solution, the secret is in these passive cooling towers that do not use water since the hot air rises from the top of the tower, the colder air is sucked in.

At its base across a set of radiators someone Long's job is to keep the radiators clean. He has to clean almost 1 million square meters of radiators with as little water as possible to achieve a better cooling effect. The 132 radiators are arranged in a V shape like this type. Passive cooling towers do not directly need large amounts of water, it is possible to build them in the desert. Eastern China is home to just under seventy percent of the country's population and more than 80 percent of its economy, yet most of the new energy resources are in the west, thousands of kilometers away, the Energy transportation has been a problem for the country for quite some time.

China plans to build more large power plants around western China's coal fields. Convert coal into electricity and then let the electrical grid transport it. to the east is the largest energy transmission project in the history of humanity today the project begins a new phase the installation of the conductors at the foot of pylon number 323 the linesman is preparing to join the conductors at the top of the air this is the world's project The longest and highest voltage power transmission line begins in the jungle basin of Far West China and runs three thousand three hundred twenty-four kilometers through deserts, mountains, canyons to the densely populated east.

In eight years, China has built more than thirty thousand kilometers of high-voltage lines to establish the world's largest power transmission network. To increase the efficiency of the system, it is necessary to increase the voltage of the 1.1

mega

high-voltage line. volts is the highest in the world at present can transmit the energy generated by 80 thousand tons of coal over a distance of three thousand kilometers in one day to ensure that the transmission runs smoothly and efficiently the 20,000 conductive joints must be connected Perfectly the cables are connected by intense pressure first the outer aluminum wires are removed to expose the steel core and then the two ends of the steel core are inserted into a metal sleeve.

A hydraulic clamp presses the sheath tightly to keep the two steel cable sections firmly together after the steel core is joined. A larger sleeve is used to connect the outer aluminum cables. The procedure seems simple. enough, but it's another thing to do it at 100 meters high with everything swaying in the breeze. Workers must hold two ends of the cables carefully and avoid damaging the conductors while dealing with the five-ton tensile strength of the cable to manage it. To do this, they must use a special cable that combines the eyeball. The work not only requires concentration but also a head towards heights.

It will take six months to complete the new 3,324 kilometer line and this is just the beginning. Several more are planned to follow in early November. A deep-sea engineering ship is anchored off the coast of southern China. The sea is calm, but Captain Jin doesn't need a storm and has already been waiting for three days. A new ship was built that cost two hundred million dollars. The waters around China are greatly affected by the currents of the western Pacific Ocean, which prevent divers from conducting operations on the seabed. This boat has been built to meet that challenge and thus test the new boat's ability to work in rough sea conditions.

Captain Jin's crew should expect some strong waves. Historically, it has been very difficult for China to develop deepwater oil and natural gas resources. Hopefully this will change if this new ship is successfully tested, it depends on whether the advanced equipment on board works to withstand the expected wind and waves. doesn't arrive captain jian has to look for another storm and the teacher thinks it only means the worst Dow's latest new weather forecast leads the captain in the Navigator to choose a new test area after a night of sailing the ship arrives at his destiny as the sea rises, the test begins.

The key requirement for precise underwater operations is that the equipment is stable even in green. To achieve this, the engineering ship must remain in a fixed geographical position against flowing currents and rough seas. This is done by the Approach Power Compensator System when the waves push the ship out of its position, the compensator system instantly activates the corresponding thruster to compensate for the force of the sea, this keeps the ship in a stable position; However, when the ship turns or is lifted by waves, the thrusters alone do not activate. enough but this new ship has other special equipment the largest crane in the world with an automatic height compensation system the high-powered crane is capable of lifting up to 400 tons as the ship rises and falls in the waves the crane automatically detects the speed and direction of movement then react instantly to compensate for this by retracting or extending your cable lines or rotating your lifting arm oh my goodness oh yeah okay grab a poncho you all will be bad you will make full use of this, TRUE? conditions the test must continue well into the night the images from the underwater camera show that the 400 ton test box only moves slightly although the waves are within the control range everyone is very satisfied with the result with the progress of deep sea engineering technology humanity has taken another step in acquiring resources from the oceans the energy stored in the depths of the sea is beyond imagination a research team leaves by helicopter for an offshore platform two hours later the team has reached its destination blue whale one of the deepest maritime operations platform in the world has been at sea for several months now the flames show that it is hard at work below the surface the fire may seem quite normal but in fact represents a world first China has become the first country to successfully extract fire ice from beneath the seabed.

Fire ice, also called fuel ice, is a common name for methane hydrate. It exists as a flammable solid in which methane is trapped in a crystalline structure of water. It was originally supposed to only exist in the outer reaches of the sea. space, but it has been discovered to exist in extraordinary quantities on Earth beneath the seabed. It forms the largest reserve of fossil fuel on the planet. However, extracting it is not a simple matter to date. Reliable mining techniques have not yet been developed. A previous mining test only lasted for 12 days before failing, the Chinese research team achieving a key breakthrough in the continuous and controllable mining of burning ice.

The pilot natural gas hydrate production team has been extracting a new world record for 60 days. After having collected a lot of data, the team decided to stop the test how you are: we don't end when you tweet, you engage in your own way, which Shambaugh doesn't, haha, can't you watch the horses go by, time does You will do well by making money, the engineers close the valves, their advancement and mining. The technology could have a profound impact on the future of energy production The rapid development of China's economy demands more energy The use of traditional fossil fuels will cause enormous environmental damage China's conscious efforts to increase the share of clean energy in its energy mix hydropower make an important contribution this is the construction site of the wooden dong the hydropower plant is one of the four cascade hydropower plants in the upper reaches of the Yangtze River excavation work has been completed to build a huge installation on the mountainside to take the giant hydraulic turbines workers are now pouring concrete to build the dam at the end of June the usually hot and dry weather turns into continuous rains this is bad news for foundry chief engineer Yong Yong Yong the papad in the free shi Shan changes to the difference charger generally, although it will not be imported, oh, in Charles Roger, that's what engineers are planning to build a seamless concrete dam around the world.

Concrete fracture is a recognized technical bottleneck, the larger the project the more serious the problem. There is an engineer who says that. Each dam has fractures, 2.91 million cubic meters of concrete will be needed to build the Wudong Dam. The plan calls for a wall 275 meters high and between 12 and 51 meters thick to withstand the pressure of up to 270 meters deep of water that the dam cannot withstand. even the slightest fracture the key to building a seamless dam lies inthe continuous control system the smelting process has to continue continuously for 33 months without interruption Jung must find a way to prevent the operation from being ruined by rain as soon as possible the young man faces a dilemma if he is cast out in the rain rain could alter the composition of the concrete if pouring is stopped the concrete components thrown before and after the rain will not mate properly to function in the rain or will wait for it to clear a decision must be made Lorraine is forecast to have cleared the area on the 29th.

Youngling decides to begin the operation as soon as it stops at 8:00 in the morning. The wet weather has passed 30 minutes later. Temperature-controlled concrete arrives on site. Monsanto goshawk changes when saying. change or you are poor - that is haunted shares a bottle woman who knew that the heat generated when concrete sets is the main cause of cracking since concrete has almost no malleability and the internal and external cooling rates are different, this distribution Uneven thermal is what can cause cracks to build a seamless dam the key is to achieve precise temperature control during the continuous casting process Jung has made a timely decision and has successfully avoided bad weather when the plant is completed powerful river waters will be channeled into the network.

However, rich water resources are not found everywhere. The city of Dulling Ha in western China is water-scarce but has plenty of sunlight. The power of sunlight and the number of hours the sun shines make it an ideal site for solar panel maintenance. Engineers have to get to work early in the day. The key components of the set are these mirrors. When the sun rises over the Gobi Desert at 7:00 in the morning, more than 20 thousand mirrors bounce the light with great precision to the top of a tower. The heat generated there is absorbed by the molten salt, which carries the heat to the plant where the water is heated until it turns into steam, which drives the turbines to generate electricity.

This way of generating electricity does not consume fuel or discharge emissions. It is an ideal way to use solar energy. However, there is a drawback. The sun keeps changing its position if the alignment of the mirrors is slightly off, there will not be enough energy to heat the salt at the top of the tower enough to solve this problem. China has developed a precise sunlight tracking system for this type of controlled photothermal power plant tower. Using a computer, the 20,000 mirrors reflect sunlight to the top of the tower when, more precisely, the region's conditions lend themselves to solar energy in general, but there is more than one way to convert the rays into vaults. , not far away, another solar power plant ten times over. of its size is under construction is a trough type photothermal power plant, unlike the tower type power plant, it collects heat from sunlight through curved mirrors, however, both systems depend on solar tracking Precise, therefore, the ingenuity of quality control manager Gülen monitors the installation of each trough concentrator.

A channel concentrator is made up of perfectly curved mirrors that track the Sun under the control of a computer. If a parabolic solar trough is not smooth, the reflected light will not be precisely focused. The installation must be done again with very precise tolerances, so what happens in Hawaii hums the area of ​​each parabolic trough is 69 square meters once the installation is completed the mirrors will be aligned with an accuracy of less than a millimeter this plant will have 9120 solar cylinders that will generate 50,000 kilowatts per hour China's currently installed solar power capacity exceeds 70 million kilowatts accounting for one-fifth of the world's solar generating capacity, more and more ways to use solar energy will revolutionize the supply of China's clean energy.

Its rapid development shows China's genuine determination to change its energy structure, but there are other emission-free energy sources that can be harnessed. China is one of the nations that has taken the lead in the search for renewable energy from the wind giant. Turbines are a common landscape feature in many places. Wind energy is often collected more reliably at sea, but the harsh environment has posed serious challenges for installation. and turbine maintenance Previously, when turbine generators were assembled on land and then transported to their operating sites by semi-submersible vessels for final assembly, the process was expensive, time-consuming and resource-intensive.

Today, offshore wind energy is increasingly looking like the future of wind energy advancements. and the installation technology will greatly reduce the cost on the east coast of China. One of these new installation methods is still being tested to ensure that tomorrow's test goes smoothly. The Director of Operations is working late to verify that the entire new method depends on this newly developed tool. He can do it precisely. adjust the angle of a blade at a height of almost 100 meters so that it is perfectly aligned with the rotor hub if the machine works as it should the installation cost of the offshore wind turbines will be finished by 11:00 at night the engineers They will have finished adjusting their settings the next day, the crucial test will begin at 7:00 in the morning.

Oh, Toronto. Rental idea in Toronto. Two hours later, a 50-meter-long, 20-ton shovel is lifted into the center. Now comes the complicated part that the team needs to join the blades together. bolts to the rotor hub 100 meters up in the air, where the slightest breeze can throw everything out of alignment. This is when the new clamping system comes into action and allows the operator precise control over the position of the blades and is connected to the hub with millimeter precision. naughty naughty three hours later the rotor blade is successfully installed this new installation method will dramatically reduce installation costs and give new impetus to the marine power generation industry in China progress in science and technology drives energy development and a mixed source of political energy is the result on a remote peninsula in eastern China the world's most advanced nuclear power unit is being prepared for commissioning the nuclear reaction releases enormous heat that is used to convert water in high pressure steam that drives generators to generate electricity the core of a nuclear power plant is the reactor unit this nuclear power unit is built to the highest safety standards in the world before it begins operating it must complete many and repeated safety inspections engineers test a three-story high security door is Made of special metals and manufactured with aerospace technologies such as the security door.

Nearly a third of the plant's components are built with the ultimate goal of safety. This 10 meter deep pool and the reaction chamber next to it are at the business end of it all. Superman created unitary years with a honey hole in the Milky Way tired of not seeing the duty you receive with Allah in due time the pool will be filled with pure desalinated water the installation and replacement of fuel rods will take place here chat about Chauvin ah, maybe yes, listen to the device ID, the inner heart of Jonathan Davies only in them, yes, we are the ones who really use it, the latest round of inspections will soon be completed, the nuclear fuel has been ready for long time in the fuel container before loading, they are stored at the highest level.

For safety reasons, more than 100 units of fuel sufficient to power the plant are already in the fuel container beneath this floor and are stored the most powerful energy source that humanity has yet been able to adequately harness its energy density. It is 2.5 million times greater than that of coal, hallelujah, the mechanical arm. captures the nuclear fuel assembly each is made up of 264 metal tubes filled with nuclear fuel before start-up they are not radioactive the operation is rehearsed repeatedly for four hours a day to ensure that when the plant begins to really operate everything will work like a nuclear clock plants run on nuclear fission the energy released by splitting atomic particles the energy released is extremely powerful but also creates dangerous radioactive waste The Sun, on the other hand, generates energy through nuclear fusion without any of this waste radioactive that scientists have long dreamed of being able to emulate this On July 5, 2017, Chinese scientists released a 100-second video that amazed the global scientific community.

The video shows an experiment in which Chinese researchers managed to reach a temperature of 50 million degrees, enough to overcome the barriers of the fusion reaction, but no material is known about it. The earth can withstand even one ten-thousandth of that temperature. What kind of container could contain such a high temperature reaction? the answer is a magnetic field the coil enters a superconducting state at low temperatures producing the strongest magnetic field on earth in this the materials can float for a fusion reaction suspended in the air judge a woman can go to other objectives Portugal all in 2008 they border very well and everything Charlie I'm Leo you do it Sonali don't take the whole window sorry friend intensity so I took your feet, eh, to decide kikuna anemia, then you go down to the generalizer, afraid of that in a Yeomans.

I realize it's Diwali here today. Titania vomits HIV loves it. Omicron's granddaughter. Hello ginger, what a mutation. Woman, don't worry. Nuclear John. -Power, although controversial, is still in its various forms, the great hope for an infinite, reliable and clean source of energy, natural renewable energies will also have their place in meeting the demands of tomorrow, while the problems of today are They drive ingeniously in the sparsely populated deserts of the world. In the West the search for a better future in which needs are met and waste is eliminated will continue. It is a green and clean future to which China is committed with all its energy.
