“Your Majesty, Your Majesty… ..”
Qin Mu was listening to Li Xiangjun reading a memorial when he heard Han Zanzhou's voice from outside the Jianjia Palace. Qin Mu heard the excitement in his voice and knew that he must have good news to report.
"Old Han, come in, what's the good news?"
Han Zanzhou walked into the hall quickly, bowed and said, "Your Majesty, Huang Sheng, it's Huang Sheng again. He made the generator and the electric light cannon. I saw it, it lights up, the electric light cannon really lights up..."
"Really?" Qin Mu couldn't help but stood up.
"Your Majesty, please go and have a look. The light bulb is really bright. This is the most magical thing I have ever seen in my life. The filament can actually light up..."
Han Zanzhou was a little incoherent, obviously overly excited.
Last year, the Internal Supervision Research and Development Department invested more than 800,000 dragon coins as funding for more than a dozen scientific research projects, including steam engine improvement, generators, tungsten filament development, aluminum alloy smelting, oil refining, and rubber refining.
However, the same scientific research results were not produced as last year. When Qin Mu just returned to Nanjing, he asked Han Zanzhou about this matter.
One can imagine the tremendous pressure Han Zanzhou was under. No one would be happy to have invested so much money but produced no tangible results.
Now, there has finally been a breakthrough. He rushed over and reported to Qin Mu immediately.
Qin Mu left the palace without saying a word and came to the Internal Supervision Research and Development Department on the west side of the Meridian Gate.
A separate small courtyard was filled with scientific researchers from the R&D Department.
As soon as Qin Mu arrived, he immediately prostrated himself on the ground. He just waved his hand, not bothering to answer them at all, and went straight into the courtyard.
"Where's Huang Sheng? Huang Sheng!"
"Your Majesty, I, Huang Sheng, am here to see you."
"Get up and take me to see your light."
"Yes, Your Majesty."
Huang Sheng himself was also very excited. He took Qin Mu to a spacious room with a long table filled with various tools and equipment.
On the left side of the room, near the window, there is a small steam engine with a belt on the steam engine wheel. The other end of the belt is connected to a simple generator. The reason why it is simple is that even the outer shell is very rough, and some copper coils can be seen from the outside.
The generator's structural diagram was originally drawn by Qin Mu for the Internal Supervision R&D Department. The structure of the generator is not complicated. The main components are copper wire and magnets.
The copper coil is fixed on a stator, and the magnet is fixed on a rotor. The rotation of the rotor means the rotation of the magnetic field, and the stator coil cuts the magnetic lines of force, generating alternating current in the stator coil.
With Daqin's current technology, it is probably difficult to produce generators on a large scale, but knowing the principle, it is possible to develop a small number for testing. Didn't Huang Sheng do it
Because there is no battery, the current generated by Huang Sheng's generator is directly transmitted to the light bulb.
He explained excitedly: "Your Majesty, I have used the heavy stone from Da Geng, refined it, and then made it into fine threads. Your Majesty, please take a look."
It would have been better if Qin Mu hadn't looked at it. He wanted to laugh as soon as he saw it. Not only was the generator ugly, but even the light bulb was so ugly. He didn't know what he used to seal the top of the glass cover. It didn't have an aluminum base like the later light bulbs. It looked like it was sealed with countless fly feces.
But no matter what, the filament inside looked like a real thing. Qin Mu finally figured it out. The heavy stone the Ministry of Industry was talking about should be tungsten ore, and the hard tungsten steel they used in the crucible to make the lathe drill should be hard tungsten steel.
And now, Huang Sheng also uses this heavy stone to extract tungsten wire.
Qin Mu didn't want to hear him explain the principles. He knew those principles as well as Huang Sheng. He wanted to see the results. "Huang Qing, come on, try it for me."
"Yes, Your Majesty."
Huang Sheng's assistants immediately took action. They first started the steam engine. The large wheel of the steam engine drove the small wheel of the generator. As the fire in the boiler became stronger and stronger, the speed of the steam engine became faster and faster, driving the shaft of the generator to rotate rapidly.
At this time, Huang Sheng went up and connected the copper wire of the light bulb with the copper wire of the generator. Qin Mu stood five steps away, staring at the light bulb closely. He saw that the light bulb first turned red, then bright, and scattered a slightly yellow light.
Watching this scene, Qin Mu's heartbeat quickened inexplicably. Electricity, Daqin could really generate electricity artificially, and even successfully lit up the light bulb.
This is a miracle, an exciting miracle!
"Hurry, close the doors and windows and lower the curtains." Huang Sheng shouted anxiously.
Several assistants immediately ran to close the doors and windows, blocking out the light from outside. The only light in the room was the light bulb, which emitted a yellow light. The light bulb was a little brighter than before and a little bit dazzling.
"Good, good, good, it really worked. Our Great Qin really has electric lights. Huang Sheng, this is an amazing invention. Your name will go down in history forever."
"Your Majesty, I dare not take credit for it. I just followed your instructions and turned your idea into reality. If you want to talk about this invention, it should belong to your Majesty."
"Hahaha... Huang Qing, there's no need to be modest. The distance between conception and reality may be only a thin line, or may be out of reach. Whoever can turn the concept into reality will own the invention."
Qin Mu kept circling around the glowing light bulb, as if he couldn't see enough.
In later generations, televisions, computers, and neon lights are so dazzling and bizarre that only a fool would stare at a light bulb.
But this is Daqin, where there are electric lights to see. Even though it is so ugly, it makes people want to hug it and kiss it.
About a cup of tea later, when Qin Mu was about to reward Huang Sheng profusely, the light suddenly flickered and went dark.
"What's going on? Hurry, open the doors and windows." The house was plunged into darkness. Huang Sheng was anxious, very anxious. He couldn't wait for others, so he ran to open the door himself, and then hurried back to check everywhere.
Qin Mu also walked up. As all the doors opened, the room was bright again. Qin Mu clearly saw a wisp of faint white smoke coming out of the glass light bulb, and the tungsten filament inside was broken.
"This... ... ... Your Majesty, I deserve to die..."
When this happened, Huang Sheng was anxious and embarrassed, and didn't know how to explain it for a while.
Qin Mu comforted him, "Huang Qing, don't worry. I want to ask you, have you pumped out the air from the light bulb and then sealed it?"
"Your Majesty, it has been drawn."
"Come, take out the filament inside and have a look."
"Yes, Your Majesty."
Huang Sheng asked his assistant to stop the steam engine, then used pliers to open the seal on the muzzle of the glass lamp and took out the filament. Qin Mu took the filament and went to the door to look at it carefully in the light.
"Huang Qing, you need to be more careful when processing the filament in the future. As far as I know, the biggest problem with light bulbs is the sublimation of the filament, because the slight difference in resistance on the filament will cause different temperatures. In places with high resistance, the temperature rises faster and the filament sublimates faster, resulting in a cycle of thinning the tungsten filament and further increasing resistance, which eventually causes the tungsten filament to burn out."
In fact, Qin Mu also knew that replacing vacuum with inert gas could slow down the sublimation of tungsten filament. In later generations, inert gases such as nitrogen, argon or krypton were injected into light bulbs to greatly increase the life of the filament.
However, no one has been able to separate inert gases yet, so more research is needed in this area.
Huang Sheng bowed quickly and said, "Thank you very much for your guidance, Your Majesty. I will definitely make improvements in the future."
Huang Sheng was filled with shame. After all, the emperor had put aside his military affairs and rushed to watch the event in person, but it ended up being smashed in front of the emperor. This made him feel very uncomfortable.
Qin Mu remained excited and comforted him, "Huang Qing, don't blame yourself. I saw that the lightbulb was on. This is more important than anything else. Everything is difficult at the beginning. You have successfully taken the first step. You just need to improve in all aspects in the future. I believe that it won't be long before I will hear good news from you again."
"I would like to thank Your Majesty for not punishing me. Thank you, Your Majesty..."
"Alright." Qin Mu heaved a long sigh, suppressed his excitement and said, "Old Han, come on, give Huang Qing a thousand gold coins..."
"Your Majesty, Your Majesty..." Huang Sheng bowed and said sincerely, "Your Majesty, as the saying goes, no merit without reward. This time, I dare not accept the reward. Your Majesty, after I improve the light bulbs and make them practical, if Your Majesty has any gift, I will accept it at any time."
"Hahaha... Fine, I like your spirit of not admitting defeat. I will keep your reward for now and double it in the future."
"Thank you, Your Majesty."
Qin Mu carefully checked his generator and light bulbs before happily leaving the Internal Supervision Research and Development Department. No matter what, today is a good day. Daqin has electricity and lights.
