Hand rubbing nuclear fusion live in the wilderness

Chapter 287 The Second Surprise for Hua
Won doesn't know if his speculation is correct, but if Huaguo really wants to remove the fuel attribute from oil.

Then there will definitely be big moves in the future, such as laying photovoltaic power plants on a large scale or increasing domestic hydropower stations.

Under the premise of de-carbon neutralization, thermal power generation is no longer suitable for Huaguo. Not only the consumption is high, the emission is high, but also the coal is easily restricted by foreign countries.

In 20 years, Huaguo imported more than [-] million tons of various coals alone.

And a large part of this comes from Australia, a country that likes to go back on its word.

Of course, [-] million tons, although this number sounds huge, is less than one-tenth of the domestically produced coal.

Every year, the domestic self-produced coal exceeds 30 billion tons, which is a proper coal-producing country.

As for why we still have to import such a high output, the main reason is that several provinces that produce coal are in the interior.

Not to mention the high mining cost, the transportation cost is also very high.

In many cases, the cost of importing coal from overseas and transporting it by sea to the eastern coast of China is even lower than the price of coal mines in the West, Inner Mongolia and other places transported to the coastal areas by land.

The coastal provinces also have to settle accounts and develop their economies, so they will naturally choose to import.

As for hydropower, nuclear power, wind power, etc., there are conditions and restrictions.

For example, hydropower, although there are places in Huaguo that are suitable for building hydropower, there are not many.

Compared with the uninhabited environment in the northwest region, which is extremely suitable for laying photovoltaic power plants, hydropower does not have many advantages.

Moreover, hydropower will greatly damage the surrounding ecological environment to a certain extent and prevent fish from migrating.

Both wind power and nuclear power have their own disadvantages.

In contrast, photovoltaic power generation is more suitable.

"If such a layout is really going to be done, then there will be another surprise."

Han Yuan thought, a smile appeared on the corner of his mouth.

If so, it would be interesting.

After he finished upgrading the chip, the next thing to deal with was the preparation of the aircraft itself.

And this includes the high-efficiency solar power generation panel 'lanthanum gallium silicon thin film solar film' that he can currently prepare.

The energy consumed by an aircraft is extremely large, and even a lithium-sulfur battery with high energy storage cannot supply it for a long time.

At the time of design, Han Yuan naturally considered and calculated this problem.

He calculated it accurately, and used the 'lanthanum gallium silicon thin film solar film' with a conversion rate of [-]% to convert and generate electricity.

When the coverage area of ​​this kind of power generation board reaches 32.16% of the area of ​​the upper half of the aircraft, as long as the energy source continuously receives light, it can completely satisfy the normal operation of the four electric propulsion engines.

Four electric propulsion engines are completely enough to fly the Relo triangular aircraft.

However, even if the power generation board covers the entire upper part of the aircraft, its conversion rate cannot provide power to the six electric propulsion engines.

There is no way, only those places can receive light.

Moreover, it is impossible to cover the entire upper half of the 'lanthanum gallium silicon thin film solar film'.

Because there are still some places that need to be used to deal with electric propulsion engines and other equipment.

According to his calculations, the maximum utilization area of ​​the aircraft is only 46.3%, which can provide operating power for five electric propulsion engines.

In fact, only one bottom-up engine is needed, plus an engine to control the direction is enough to make the aircraft fly.

After all, the total weight of the entire aircraft he designed was only [-] tons on the design drawing.

An electric propulsion engine with a thrust of up to 150KN is enough to send a modern fighter jet weighing more than ten tons into the sky.

The thrust of the F22 engine in the United States is only this data, and the maximum take-off weight of the F22 exceeds 27 tons.

Of course, this requires a certain slide rail to support.

Because thrust isn't everything, there are many other factors that need to be considered in the design of an aircraft.

Like thrust-to-weight ratio or something.

"The ratio of the maximum thrust of the jet engine used by the aircraft on the horizontal plane to the net weight of the engine is called the thrust-to-weight ratio of the aircraft engine."

The thrust of 150KN seems to be great, but it is not enough to allow the 'Leroy triangle aircraft' he designed to achieve vertical take-off and landing.

To achieve vertical take-off and landing, at least two electric propulsion engines must work simultaneously.

Resistance and area are directly proportional.

Modern means of transportation, whether it is low-level cars, ships, trains, or high-end aircraft, fighter jets, aviation rockets, etc.

The main reason for the continuous design and optimization of the shape is to reduce the resistance and thus increase the speed.

Especially for fighter jets, the application of aerodynamics on it is simply incisive and vivid.

If South Korea designed the aircraft to look like a modern fighter jet, there would be no need for six electric propulsion engines.

One is enough.

Even if it is to prevent problems such as engine failure, adding one or two is enough.

But he can't, he can't fly
And you have to fly the aircraft around the entire simulated planet to get extra rewards for the mission.

So South Korea can only make the aircraft like this, which can realize the function of vertical take-off and landing.

After all, the vast majority of aircraft accidents occur during takeoff and landing.

If vertical take-off and landing can be realized, the danger will be greatly reduced.

Of course, these are his next jobs.

What Han Yuan thinks is that those "lanthanum gallium silicon thin-film solar films" with a conversion rate of [-]% that are applied to aircraft will bring a huge surprise to his motherland.

With the ability of Huaguo, the nickname of infrastructure madman.

When this photovoltaic power generation technology is fully mature, I am afraid that all places in Northwest China that are suitable for building 'photovoltaic power plants' will be covered with 'lanthanum gallium silicon thin film solar film'.

Although both lanthanum and gallium are relatively expensive, the proportion of lanthanum and gallium in the "lanthanum gallium silicon thin film solar film" is very small, and the total proportion of the two is less than [-]%.

Relatively speaking, the cost is not very high.

If the proportion is high, it is naturally not worth it.

Large quantities of 'photovoltaic power plants' will be laid, and domestic electricity prices will be quickly brought down.

Not to mention the extent to which civilian electricity will be reduced, even if the industrial electricity consumption is reduced by a dime, the enterprise will save countless costs.

And these costs can be fed back to research and development. Such a virtuous circle will naturally lead to a better path.

Although it is unavoidable that some unscrupulous bosses will swallow all these benefits, such a road is destined to not last long.

Without the competitiveness of core products, the wheels of history will ruthlessly crush them.

Before nuclear fusion is developed, this will be the most beautiful way of power supply.

Shaking his head, Han Yuan recovered from his imagination and continued to process the materials in his hand.

'Chemical Vapor Deposition - Silicon Core Epitaxy' has a total of seven steps.

The first five steps take a relatively short time, but the sixth step is relatively time-consuming to form single crystal silicon on the sacrificial layer.

According to the sacrificial layer he currently sets and the thickness that needs to be generated, it will take at least six hours or more.

The higher the thickness that needs to be generated, the longer the corresponding time will be.

Of course, this is not a shortcoming of the 'chemical vapor deposition-silicon core epitaxy method', it can only be said that it takes a long time.

Even with the single crystal furnace Czochralski method, it takes more than five hours to smelt the single crystal silicon he needs.

But don't forget, 'Chemical Vapor Deposition-Silicon Core Epitaxy' can produce single crystal silicon in batches controlled by computer.

Especially in the sixth step, the epitaxial method with silane gas as the core only needs to control the input speed of silane gas.

This step requires no human supervision at all.

However, this is based on the supervision of intelligent computer programs. As far as Won is concerned, he still cannot do without manual supervision.

It took more than six hours, from the busy afternoon to more than eight o'clock in the evening, before the single crystal silicon in the preparation equipment was extended to the thickness he needed.

At this point, the extended preparation of single crystal silicon has been completed.

The rest is to wait for the single crystal silicon in the instrument to cool down naturally and slowly, then separate the connection between the single crystal silicon layer and the sacrificial layer and the substrate, and then slice it, and then it can be used.

The whole process is not complicated for someone like Han Yuan who is cheating, especially after more than two years of development of genetic enhancement drugs, the body has long been able to adapt to various machine operations.

After processing the monocrystalline silicon, Han Yuan glanced at the time, greeted the audience, and then went live.

It was past eight o'clock, and it would take about two or three hours for the monocrystalline silicon in the preparation equipment to completely cool down.

At that time, there is no time to continue to deal with it, so it is better to order some delicious food early and have a good rest.

After all, this period of time is almost crazy, and the iron robot needs some lubricating oil, let alone a mortal one.

Under the moonlight, Han Yuan set up a table of meals, drank monkey wine and petted the big cat, enjoying the rare leisure.

Over the past few days, it has been proved that the human body develops medicines that can strengthen the body in a targeted manner along with the body's own activities.

From the beginning of the test, he obviously felt that the effect was on the third day, and the sleep of about four hours was not enough at first.

But after three days, on the fourth day, Han Yuan felt that the sleepiness during the day gradually decreased.

There is a strengthening effect of manipulating the human body's own activities, but the onset time and effect do not seem to be as fast as the autonomous ones.

And the strengthening effect seems to have a limit.

After knowing the effect, Han Yuan began to try to further reduce his sleep time, and wanted to see if he could not sleep 24 hours a day.

But in the end until now, he can compress his sleep time to four hours at most.

Four hours of sleep time is the limit, and if it is shortened, it will not be able to guarantee the energy for activities during the day.

Although it is a bit regretful that I can't sleep all day, I am very satisfied that the sleep time can be reduced to four hours.

This represented an additional two or three hours in the time he could spend on the task.
