"Oh? Lawrence also used the Stirling heat engine?"

Catherine thought it was quite funny that Lawrence actually used the Stirling heat engine for solar generators.--(

"Stirling heat engine? What is that?" Elsa asked strangely.

"An older heat engine."

What is a Stirling heat engine?

The ideal thermodynamic cycle of a hot gas engine (i.e. Stirling engine). It is a reversible cycle composed of two constant volume heat absorption processes and two constant temperature expansion processes, and the heat released by the constant volume heat release process is exactly the constant volume heat absorption process.

Absorbed by the process. The heat engine absorbs heat from the high-temperature heat source during the expansion process at constant temperature t1, and releases heat to the low-temperature heat source during the compression process at constant temperature t2.

Stirling cycle can be divided into 4 processes:

1. Constant temperature compression process: the valve piston stays near the top dead center, and the power piston compresses the working fluid upward from its bottom dead center. When the working fluid flows through the cooler, the heat generated by the compression is dissipated. When the power piston reaches its

The compression process ends at top dead center.

2. Constant volume regeneration process: the power piston still stays near its top dead center, and the valve piston moves downward, forcing the working fluid in the cold chamber to flow into the hot chamber above the valve piston through the regenerator, and the low-temperature working fluid flows through

The regenerator absorbs heat and raises the temperature.

3. Constant temperature expansion process: the valve piston continues to move downward, the working fluid is heated by the heater, expands in the hot chamber, pushes the power piston downward and performs work externally.

4. Constant volume heat storage process: the power piston remains near the bottom dead center, the valve piston moves upward, and the working fluid returns from the hot chamber to the cold chamber through the regenerator. The regenerator absorbs the heat of the working fluid, and the temperature of the working fluid drops to the cold chamber.

temperature.

The theoretical energy conversion efficiency of the Stirling heat engine can be infinitely close to 100%. If it can be used, it will definitely be a weapon that can block and kill gods. Historically, it was banned for a long time because it killed too many steam engines instantly. Later,

When people turn their heads again, the internal combustion engine is already 100 years ahead, and it is naturally impossible for the Stirling heat engine to catch up.

——But Catherine does know one thing, that is, in the 21st century, this kind of heat machine has been proposed again.

"But there should be some in Japan now...?"

Catherine remembered that the Japanese seemed to have done it before, but failed. She remembered that this seemed to be last year.

——Nonsense, it’s ridiculous that technology that has been stagnant for 100 years can still be easily applied.

However, this external combustion engine technology, which has been rarely mentioned in 100 years, is already close to that of diesel engines.**--*

The main advantage of a gas heater is that it can use a variety of energy sources. Whether it is liquid, gaseous or solid fuel, when indirectly heated using a heat transfer system (such as a heat pipe), almost any high-temperature heat source (solar energy, radioactive isotopes and nuclear reactions) can be used

etc.), and the engine itself (except the heater) does not require any changes.

For Catherine, the external combustion engine is very stable and has minimal vibration. This is a technology that Catherine cares about infinitely.

The actual cycle efficiency of the hot gas engine is higher, and there are fewer harmful components in the exhaust gas. The noise is lower. Because the fuel is continuously burned under more excess air, the hot gas engine does not require a valve mechanism, and there is no explosive combustion. The operation is smooth and the vibration is small——

Isn't this what Catherine has always wanted to pursue?

Compared to the motor, the heat gas machine has good torque characteristics within a very wide speed range. It is suitable for vehicle use. The torque of each rotation of the crankshaft is not uniform, and the consumption of lubricating oil is also small.

Not suitable for climbing, it can only be used in the city.

"Oh ... I all want such an external machine ..."

Catherine pondered that since the Japanese are studying this technology, they just buy it.

Anyway, Catherine has never heard in the 21st century. What an external combustion machine is very good.

The main problems and disadvantages of heat -gas machine external combustion machines are that the manufacturing cost is high, the technique of quality sealing is difficult, the reliability and life of sealing parts still have problems, the power adjustment control system is more complicated, and the machine is relatively bulky.

But for Catherine, these are not problems. It is enough to use tempered carbon nanotuba fiber.

Although this kind of carbon nanotuba fiber is very troublesome, it is a very easy -to -use "thousands of gold oil" products, because the chemical properties are extremely stable, can resist high temperature, low temperature resistance, and high hardness.

If you run, there is no place that cannot be applied.

To the extreme, this kind of steel carbon nanotherapy fiber can even build a whole city!

"This technology of the external combustion machine can be available ... Elsa, you see, there seems to be applications in Japan. When we look at, we will get their patents."

Although this technology has been more than a hundred years, the development of so many years must have related new technologies.

"Hmm ... by the way, this technology of making hydrogen energy is also good, using plant extract glucose ... but why do I feel that it is no different from that of making alcohol for vineyle?"

What do you think, this seems to be almost the same plan. Lawrence dug too many pits for himself. As a result, he had to be sick and applied for medical treatment. In Catherine, although these technologies were a bit bullish, they were indeed ... uh ... uh ... uh ... uh ... uh ... uh ... uh ...

There is no different.

"But if it is new energy, development is worthy of affirmation ..."

Although Lawrence made things bad, in the end, Catherine still agreed with the other party's actions.

The development of new energy is necessary.

For Catherine, the only purpose of developing green energy is not for environmental protection.

—— but to break the energy monopoly.

Using new energy to break the energy monopoly based on oil based on the old world, this is what Catherine wants to do.

Catherine's ultimate goal is to dominate and transform the world.

Well, is this goal that can be achieved? It is still two sayings, but with this purpose, Catherine is also a motivation for his own development.

It is not the end point, but the mood of the journey. This sentence is used to describe Catherine the best.

Everything in the old world can be said to be based on oil and coal.

Without coal, there is no thermal power, and most of the worlds in the world will lose electricity. The so -called electronic products will also become a pile of jokes.

Without oil, almost all traffic will break -even the aspiration road will be gone, it is even more terrible world.

The best and only way to challenge this world fundamentally is to control energy.

In the traditional energy industry, Catherine does not want to involve it.

In that case, maybe I can become a flag-bearer in the end, but that's not the best.

Just like Han Miemen is best at flipping the chessboard, what Catherine is best at is opening a new game - you play yours, we play ours, and when everyone likes us, we will go over and give your chessboard to you.

Flying.

We are not interested in the traditional oil chessboard, so we played a chess game, and the name of this chess game is: green energy.

What's more, the rules of the current chess game were set by Catherine.

"Green" energy has two meanings: one is to use modern technology to develop clean, pollution-free new energy, such as solar energy, wind energy, tidal energy, etc.; the other is to turn harm into benefit, combine it with improving the environment, and make full use of urban garbage, sludge, etc.

The energy contained in waste. At the same time, a large number of automation control technologies and equipment have been popularized to improve energy utilization.

In the past, since 1987, industrialized countries have used solar energy, water power, wind power and plant energy to obtain electricity equivalent to the energy of 9 million tons of standard coal, and this increase will be an average of 15% per year during this century.

Growth rate of 19%. From 1981 to 1991, the turnover of industrialized countries in wind and solar power generation equipment alone reached 12 billion US dollars. Among them, the United States, Germany, Japan, Sweden and the Netherlands made the fastest progress.

In the foreseeable future, it is difficult to change human energy demand habits, and oil and coal will still be the main sources of primary energy consumption. However, with the continuous technological research on renewable energy in the future and the development of the market, the structure of human energy consumption has begun to change.

There have been significant changes, and the development path of green energy has gradually become a consensus.

And for Catherine, the world is the least lacking.

Maybe the oil at this time is still enough, but... what about 100 years from now?

Maybe other people won't care about the technology 100 years from now, but for Catherine, the technology from the future is not an illusory thing.

Ordinary companies rarely have long-term strategies, and even century-old companies will inevitably decline at some point.

This is due to their own limitations. Perhaps the original strategy makers had an excellent vision, but they still did not imagine what the world would be like a hundred years later, and what their technology would be able to do.

To what extent.

A flourishing century-type enterprise may be able to prosper for a hundred years, but after a hundred years, the advantages accumulated by its predecessors will be gone. And if they do not have a leader with an overall view, the enterprise will not be able to survive for a hundred years.

It is difficult to continue to develop.

But Catherine is different. Her natural advantage gives Catherine a time advantage. She can jump out and see everything in the world from a longer perspective, so she can also make longer-term plans for her business.

Just like now.

While every company is formulating their strategies for the next few years or more than ten years, Catherine can think of a more distant tomorrow. Catherine's current preparations are all made for the development of that distant tomorrow.

Her technology and skills are the stars of tomorrow!
