"Your Majesty, the number of tungsten filament incandescent lamps produced by the Academy of Sciences exceeds 2,000. Are they installed in the main streets of Chang'an City with the help of power provided by Chang'an Electric Power Company?"

"Have the vacuum properties of incandescent lamps and the smelting problems of tungsten wire been solved?"

"The Academy of Sciences adopts the method of filling the interior of the light bulb with nitrogen and smelting tungsten metal by electrolysis, which basically solves the problem of vacuum in incandescent lamps and the cost of smelting tungsten metal. The current cost of making an incandescent lamp has been shortened from 10.7 Chinese yuan to 5.2 Chinese yuan.

, it is initially possible to install it on the main street of Chang'an City."

The production cost of light bulbs and the cost of electricity are two major problems that limit the widespread use of incandescent lamps. The cost of 6.2 Chinese yuan per lamp and 2.4 Chinese yuan per month for electricity is still a price unacceptable to ordinary people. Therefore, the current tungsten filament incandescent lamps

It can only be used in the main urban area of ​​Chang'an, the capital city.

"For the time being, 600 incandescent lamps will be installed in six streets in the main urban area of ​​Chang'an. At 6 o'clock every evening, electricity will be delivered by the power company regularly."

"Yes, Your Majesty."

The Director-General of the Ministry of Industry took note of Li Mingyuan's order and asked thoughtfully, "Is the V-type twin-steel gasoline engine developed by Mr. Daimler also included in the announcement?"

"No, gasoline internal combustion engines do not yet have the ability to be widely used. In the next five years, local research on gasoline internal combustion engines will focus on technology reserves, and implement a three-generation technology replacement system of open commercial generation, technology reserve generation, and research and development generation.

To put it bluntly, it means that the internal combustion engine technology that has the same or slightly superior scientific and technological performance as that of the Western powers will be put into commercial production, which will lead the commercial field, and the internal combustion engine technology that has been basically mastered will be kept secret, which will far exceed the current technical level and is not yet available.

The internal combustion engine technology put into market production will be included in the key research and development list, and major scientific researchers will be centralized for research and development."

Having a prophetic vision in the field of science and technology can save Han researchers from many detours. For example, in the field of internal combustion engines, when the internal combustion engine project was initially established in 1876, the development direction of gas-type internal combustion engines was rejected, which made the relevant scientific research of the Academy of Sciences

The staff can focus on the gasoline-type internal combustion engine from beginning to end.

"The overall level of domestic scientific research is still far behind that of Western countries. Electric lights and hydropower station projects are put into commercial use and cannot be hidden from the eyes of Western countries. There is no harm in making them public. However, research and development projects related to the core interests of the country, such as internal combustion engines, submarines, and airships, must not be leaked.

Every bit of information!"

"Yes, Your Majesty!"

More than a dozen officials sitting on palace chairs stood up and said seriously.

"The United States, France, the United Kingdom, and Germany are all conducting research on the technical performance of submarines. Although Holland, an American, rejected the invitation from the local government, the main strategic uses of underwater submarines, including the application of periscopes on submarines and other details,

I have also made many suggestions to the R&D personnel of the Academy of Sciences. The Han country cannot rely too much on Westerners for its local scientific research technology. Without Huo Lan, the Han country will still have to develop super-first-class underwater submarines!

Minister Liu, please give an order to the Navy. There is no need to rush the submarine research and development project. I can afford to wait for ten or twenty years. However, if the submarine project has not broken through the practical technical difficulties in offshore operations before 1900, I will pursue the case.

They failed in their duty!”
