At the beginning of the large-scale expansion and investment, because many children and even teenagers were in the process of cultural make-up classes and even selection and training, they did not see any revolutionary mechanical inventions until Chongzhen's twenty-five years. The failure of countless common sense in the field of batteries and capacitors and steam engines has even begun to shake the confidence of many people. However, in the field of petroleum distillation and even delysis, which seems to be far away from the steam age, it has achieved considerable results. The "internal combustion engine" powered by heavy oil, diesel, gas and other fuels was first successfully trial-produced in the laboratory of the Central College.

With a lot of accumulation in the field of metal processing and smelting in the past ten years, at least in today's Central College, the processing and production of cylinders and pistons still have a very high technical level. Especially when the first batch of senior engineers began to take shape.

Of course, this is obviously still a long way from large-scale promotion and application, and even the manufacture of barely usable cars and power boats under the condition of subsidies. Obviously, the research laboratory and affiliated workshops of the Central Academy are to a large extent similar to the chip industry at some time on the eve of the reopening, belonging to the "lack of equipment and skillful hands", relying on the concentration of a large number of skilled people in the field of handicrafts and even manual machine tools to make up for the lack of production equipment, and entered the technical level of the era of the second industrial revolution in advance. However, in the wider public sector, it is clearly still at the level of technology that existed before the steam revolution.

Although there have been many revolutionary innovations in the institutional mechanism and even culture of the whole society, the whole Ming Dynasty today is still to a large extent more similar to a certain industry-university-research mechanism in China in the era of the Soviet Union or the planned economy. In the case of model engineering manufacturing and small batch trial production, the engineering ability is good, and there is a huge gap in promotion. It is clear: this is the result of the failure of the production equipment to effectively break through in some places.

In history, from the Renaissance era to many key breakthroughs in the eighteenth century and even many improvements in the nineteenth century, the other dimension of world history has a long accumulation in the field of machine tools, obviously not in the large-scale investment in science and education can be fundamentally improved in just a few years after the rollout.

However, unlike engines, which require advanced technology and accumulation, many new consumer products, such as kerosene lamps and kerosene, new stoves, central heating, and running water and water towers, may cost a certain amount, but new consumer products that do not require too much skill or even craftsmanship are gradually spreading in the central governor's district, centered on Onten. After all, compared with Britain in the era of the early industrial revolution, the accumulation of high-level skilled craftsmen and even the accumulation of national cultural level in the whole society today provides a large number of high-quality labor force, which in many respects still makes up for the limitations of industrial production equipment.

Probably from the winter of the twenty-seventh year of Chongzhen, when the large-scale investment in science and education was rolled out for about four or five years, some problems that had long plagued many experts and scholars in the Central Academy gradually revealed the mystery, and Xiao Xuan also seemed to have a sense of enlightenment.

Obviously, after the coverage of education has expanded to the level of millions of people, the scientific research and education mechanism and even the selection mechanism and the academic atmosphere have not been greatly ill, and some geniuses who have historically belonged to the century level have also begun to gradually become prominent at this time. After all, after many years in history, the real universal education was only rolled out in the range of hundreds of thousands, and it was not until the late nineteenth century that there was really a decent universal education.

After the improvement of several geniuses, the steam engine is no longer just a symbolic "jet", and when some technical bottlenecks have just been broken, the thermal efficiency of the estimated 10% has been reached in the laboratory of the Central Academy. Unlike many Western inventions in history, which were "launched by local law" under the condition of simplicity or limited human capital, this plane with more planned economic colors, although many inventions and breakthroughs are relatively "difficult to deliver" under the mention, but once they break through, they will have a high level of quality and even excessive application. For example, when the reciprocating steam engine could be applied at the beginning, there were reliable rubber products and steel. In the following two years, in order to process pipes quickly and at low cost, the machine tool also quickly made many breakthroughs and improvements

Cylinder boring machines, thread cutting lathes, tool holders and guide rails, machine tools that can turn threads of different pitches, cast iron beds, idler pulleys with exchange gears, gantry lathes, hydraulic and even steam-driven lathes, gear hobbing machines and length measuring machines, turret hexagonal lathes, and many other practical technologies that Xiao Xuan had never heard of before began to spring up like mushrooms under the suitable soil in the following years. Of course, it all started with a strict system of parts standards, lengths and definitions of various units. Compared with the West in the era of the industrial revolution in history, there is no doubt that many detours have been avoided.

After a series of changes and even innovations in the field of machine tools, many technologies that had previously only appeared in the experimental field of the Central Academy began to spread and spread. What Xiao Xuan didn't expect was that not only did the usable steam engine appear not long after it reached a thermal efficiency of more than 10% in the environment of "everything is ready only for the east wind", and the cylinder chamber pressure reached twenty or thirty atmospheres, and even the two-stroke or four-stroke diesel, gas, and gasoline engines had just appeared, and after several years of testing and investment, the efficiency of the piston engine began to reach the level of about 70 kilograms and 20 horsepower. T-sized automobiles and even early-class aircraft began to appear widely at this time. Airships began to mature soon after they appeared.

Seemingly simple, but in fact not simple bicycles also began to enter the stage of practical use at this time, but the field of electricity and electronics, which was once highly anticipated, does not seem to have exploded rapidly, and technologies such as photography, which appeared in similar eras, have not appeared.

For a long time in history, the so-called science and technology were in fact just a hobby of the upper class. Its role in promoting society as a whole was gradually recognized in the long period of the nineteenth century, which lasted nearly half a century. However, from the 25th year of Chongzhen to the 30th year of Chongzhen, in just a few years, a large number of amazing technologies appeared rapidly and were quickly promoted, which finally made many people once question the huge investment in science and education, and even the extremely radical social changes, and even the price paid for it, more or less began to have a trace of understanding.
