Ang Lee installed a variety of light bulbs in Li Longji's bedroom. There were warm and romantic pink light bulbs, warm orange light bulbs, dreamy blue light bulbs, and even more amazing colored light bulbs.
The so-called colored light bulbs were small boxes made of thin copper wire, small wooden edges, and translucent silk with beautiful patterns. They were hung from the top of the head and had a relatively large surface area. They were actually transformed palace lanterns. The principle was very similar to palace lanterns, but the surface area was larger and the thickness was flatter. In the future, they were called ceiling lamps.
This kind of ceiling lamp would become extremely beautiful when the light bulb was lit at night. The light would illuminate the pattern on the silk. Moreover, it would be more beautiful than usual. Especially when lying on the bed, one would see the beautiful bright pattern as soon as he opened his eyes. How comfortable and cozy that feeling would be.
After the various lamps were installed, Ang Lee had the eunuchs draw all the curtains. He wanted to see the effects of the lighting arrangement.
After all the curtains were drawn, Ang Lee began to test the effects of the lighting one by one.
When all the pink light bulbs were turned on, the entire room was filled with a romantic and warm pink. When the orange light bulbs were turned on, the entire room became brighter. When the blue light bulbs were turned on, standing in the room was like standing by the sea. The mood was calm and comfortable. After the colored light bulbs were turned on, the room became even more beautiful.
When all the light bulbs were turned on at once, the room was as bright as daytime.
"Assistant Minister Li, the effect of the lighting is so good. His Majesty will definitely be happy. When the time comes, there will be no shortage of rewards."
Seeing the results of their labor so splendid, the craftsmen were very happy.
"This official has never lacked rewards. It's you guys who are always thinking about rewards! Don't worry, as long as you work hard, there will be no shortage of rewards in the future. This time, this official will also report to His Majesty and help you ask for rewards. "
Ang Lee promised, encouraging the craftsmen to continue working so that they could do their work perfectly.
When these craftsmen heard that there was a reward, they worked even harder. After all, the better they did, the more rewards they would get. If they didn't do a good job and made Li Longji unhappy, the reward might be gone.
In addition to supervising the craftsmen, Ang Lee also found many eunuchs to teach them how to use and change the light bulbs. He also let them do it on the spot so that they could learn this very low-level technology.
Ang Lee insisted on letting the eunuchs learn how to change light bulbs because light bulbs had a lifespan. If they broke, they definitely needed to be replaced. It was obviously not appropriate to let the craftsmen go to the emperor's bedroom to change light bulbs. However, there was no such problem with letting the eunuchs change light bulbs. Moreover, the eunuchs only had slight physical disabilities. Their brains and intelligence were not much of a problem. Learning how to change light bulbs was absolutely appropriate.
In addition, in addition to letting the eunuchs learn how to change light bulbs, Ang Lee also wanted to set up an electrician team made up entirely of eunuchs. If there were any abnormal problems with the circuit system, these eunuchs would be responsible for repairing and inspecting it. This way, it would avoid a lot of inconveniences caused by the craftsmen entering the palace.
The electrician team made up of eunuchs would naturally belong to the Internal Servants Province. After all, they were eunuchs. Only belonging to the Internal Servants Province was the most appropriate.
After having this idea, Ang Lee only mentioned it to Gao Lishi. In the end, Gao Lishi immediately agreed. He wouldn't bother Li Longji with such trivial matters. He had the authority to make the decision. Moreover, he was the highest-ranking official of the Internal Servants Province. The eunuchs' electrician team would be a department under his command. It was naturally a good thing to have more departments under his command.
After all the installation work was completed, Ang Lee carried out a detailed inspection of the overall situation and had the craftsmen do the same. After confirming that there were no problems, he brought the craftsmen and some of the eunuchs back to the research and development center.
After returning to the research and development center, Ang Lee continued to do research. He had a few craftsmen teach the eunuchs the simplest knowledge so that they could grasp the most basic knowledge of electricity as soon as possible. As long as they knew how to deal with small problems, there wouldn't be many opportunities to really encounter major problems. When the time came, they could just let the technical personnel handle it.
That night, when Li Longji and Yang Yuhuan moved back to the bedroom, they saw that the lighting in the bedroom was much better than in the courtyard in the south. Naturally, they were very happy. Under the guidance of the eunuchs, they began to familiarize themselves with the various lighting and lighting effects. In the end, they chose the warm and romantic pink lighting and enjoyed a good time inside.
The technology of manufacturing generators was gradually maturing. It was very simple to make electric light bulbs. As for the spotlight, it was even simpler. They only needed to put a bowl-shaped reflecting surface in the position of the bulb and put a convex lens in front of it to realize the convergence and transmission of light. It could be used to make searchlights.
As the electric light was extremely important to the future development and prosperity of Chang 'an, the research and development center carried out an emergency mobilization to speed up the construction of power generation equipment in batches and immediately deployed it everywhere in the capital.
Daming Palace, Taiji Palace, and Xingqing Palace were the first to deploy power generation equipment. Following them were the East City and West City, then the important streets and squares in the northern half of the capital, and finally the squares in the southern half of the capital.
Due to the different importance, the density of the deployment of power generation equipment was different. The Imperial Palace, East City, and West City had more power generation equipment, so the density of the lights was very high. However, the squares in the southern part of the capital only had one power generation equipment installed in two or three squares. Moreover, they had to pay for the needs of the surrounding street lights, so they looked relatively dark.
In addition, the deployment of the street lights adhered to the principle of deploying more in the important areas and less in the secondary areas. The Vermilion Bird Avenue in the central axis of the capital and a street in the southern part of the Imperial City had the most street lights. At night, the street lights could illuminate the road as if it was daytime. As for the smaller streets, the number of street lights deployed was relatively less. As long as the street lights could be seen clearly, it was enough to ensure that the ordinary people could walk.
In order to create the prosperity and luxury of Chang 'an, many light bulbs were also installed on the city wall of the capital. Moreover, the spotlights shone on the wall, illuminating the city wall as if it were daytime.
At night, standing not far from the city wall, one would feel very comfortable to see the very bright city wall. This was especially true for the people from the small countries. When they saw this scene, they would be deeply shocked and sincerely admire the prosperity and power of the Tang Empire. Thus, they would not dare to covet and invade it.
Sets of power generation systems, while meeting the needs of the capital, were also installed in the research and development center and many workshops outside the city. Of course, the very important railway station was also installed to meet the needs of these areas.
After some time, the power generation carriage developed by Ang Lee was also completed. It was soon mass-produced. In this way, the trains could be connected to electricity. When running at night, each carriage no longer needed candles. Instead, it was directly replaced by light bulbs. A number of high-power searchlights with strong light gathering were installed at the front of the carriage, which greatly enhanced the safety of driving at night.
Of course, the number of electric lights installed in each carriage was different. The best soft sleeper carriage had two light bulbs installed in each small compartment. There were also eight light bulbs installed in the aisles. In this way, the entire carriage was installed with 20 light bulbs.
There were only 10 light bulbs in the soft sleeper carriage. There were 12 light bulbs in the hard sleeper carriage. There were only six light bulbs in the hard seat carriage. The stable carriage at the back only needed three light bulbs. Moreover, it did not need to be turned on often.
In fact, the dining carriage was equipped with the most light bulbs. Because the dining carriage was a place for eating and cooking, it needed to be seen more clearly. The entire dining carriage was equipped with more than 30 light bulbs. At night, the entire carriage could be illuminated as if it were daytime.
Due to the large number of trains and the heavy responsibility of the R&D Center, it was impossible to connect all the trains with electricity in a short period of time. It would take at least three to five months for all the trains to be popularized.
In addition, batches of steam-powered seagoing ships had been gradually launched and assembled. There were even five or six ships that had begun sea trials. Therefore, Ang Lee had to speed up the development of a power system suitable for large steam-powered seagoing ships so that these ships could use searchlights to observe their surroundings at night. In addition, with the addition of electric light bulbs, the cabins would be cleaner and brighter. This would greatly improve the comfort of the crew.
Due to the same principle, a generator suitable for large steam-powered seagoing ships was created in just a few days. It immediately began mass production to meet the needs of the steam-powered seagoing ships of the Grand Imperial Residence.
"Alang, the canned food you made last time has been stored for three months. Can you open it now? It's probably gone bad."
Zhao Liu walked to Ang Lee's side and said.
"Canned food? If you didn't mention it, I would have almost forgotten. Quick, bring the canned food over. Let me have a good taste and see if it has gone bad."
Ang Lee was very curious about whether the ceramic canned food he made could still be eaten after three months. If it couldn't be eaten, his experiment could be considered a complete failure.
"Alang, do you want to open it now?"
Zhao Lu brought out six cans of food. The contents and locations of these six cans were all different, so the time they could be preserved was definitely not small.
"Open it, open it all."
Ang Lee ordered and opened a can himself.
"Not bad, it's still fresh. It's edible."
Ang Lee smelled the aroma of the mutton and put a piece into his mouth. It was quite delicious.
"Alang, it's really fresh. The taste of the celery is still the same as when it was freshly made."
"Alang, pork is also good. It's edible."
Zhao Lu opened many cans of food, grabbed the food inside, and began to gobble it up.
"It's been three months and it hasn't gone bad. Even the mutton placed in a hot and humid environment is still fresh. This is enough to show that the canned food technology is reliable."
Ang Lee said happily and immediately asked Zhao Liu to set up a canned food factory to produce canned food.
Zhao Liu was naturally very happy. He began to arrange for the male and female servants under his command to set up this profitable project.
For the canned food, Ang Lee originally planned to use glass materials. After all, the cost of glass materials and pottery materials was not much different. Moreover, glass could clearly see the food inside. It was much better than pottery.
But at present, Ang Lee is strictly confidential about the manufacturing method of glass. The price is often dozens of times or even hundreds of times the cost. If canned food is still sold at such a high price, the price of the glass bottle is already very terrible. Ordinary people can't afford it at all.
If he were to lower the price and sell it at a normal price, then the true cost of the medicinal jade would be doubted. In this way, the most profitable industry that Li An relied on would collapse. Many people would even secretly curse Li An for being black-hearted, actually selling something that cost a few hundred times the original price.
After thinking about it again and again, Ang Lee decided to develop ceramic canned food and achieved great success. Anyway, ceramic products are cheaper and the price of the finished product can be more affordable.
Of course, since ceramic products have been successful, canned food made of glass will definitely not be a problem. Ang Lee's canned food factory can make a small number of canned food and package it in beautiful packaging boxes as a high-end gift. In this way, many rich businessmen will buy some canned medicine jade bottles and then give them to the people they need to curry favor and maintain.
As for the entire canned food industry, Ang Lee decided to hand it over to Zhao Liu and his wives to take care of it. The previous medicinal jade industry will also be handed over to them. Zhao Liu is responsible for taking care of it outside, while Ang Lee's wives are responsible for calculating the property at home and doing the logistics work. This can also make their lives more fulfilling and not too boring.
The canned food factory was started immediately. It was done in a few days because the houses were ready-made. They were in the processing plant next to Ang Lee's courtyard. Moreover, electricity has now been connected. They can work in shifts day and night.
Because people in this era are more able to endure hardships, the demand for entertainment is relatively less, and there is no supporting labor protection law. Therefore, as long as it is work, they basically have to work overtime. The working time in a day is at least twelve hours, which is twelve hours in the future.
Ang Lee was a wage earner who was exploited in the future, but at this time, he chose to exploit the working class very black-hearted. Moreover, for his own workshop, he had to implement a very inhumane two-shift system. One shift during the day and one shift at night. There is no rest and holidays. If there is something that can't be done at work, you need to ask for leave in advance. Otherwise, it will be considered absenteeism, and your salary will be deducted.
