The emperor thought to himself, reached into his purse and pinched out a silver coin, handed it to Fan Xiaohui, and said, "Go buy two bottles of thirst water, there are people selling it over there."
"Master, please wait a moment." Fan Xiaohui happily took the silver coins, trotted to the roadside stall, and brought back two bottles of thirsty water in a short while.
Zhu Youxiao had to admire the businessmen's shrewdness. When they were thirsty, they no longer had to drink from a bowl at the stall. Instead, they made some ceramic bottles that looked like small wine jugs.
You can either throw away the bottle of thirsty water after drinking it, or buy more at a thirsty water stall and refill it. Of course, bottled thirsty water is more expensive, but there is still a market for it.
"This bottle is interesting." Zhu Youxiao looked at the bottle and took a sip. It was a sweet water with a citrus flavor, not bad.
Fan Xiaohui held it like a small vase and said with a smile: "Master, I can put some flowers in it when I take it back."
Zhu Youxiao chuckled and heard the sound of copper coins in the maid's waist bag. The errand fee was in her pocket. No wonder she was happy!
The Academy of Sciences remained in its old location, but a new branch was built in Huangzhuang, just outside the city. This was mainly because some of the work required more space, and the noise from manufacturing equipment within the city was a bit disturbing to the residents.
For example, the improvement of hot air balloons was moved outside the city, and some crop planting experiments were also moved to the imperial farm outside the city.
Even so, when the emperor and others arrived at the gate of the Academy of Sciences, they still heard clanging sounds from inside.
Inside, there weren't many people coming and going, probably because of the diversion. Zhu Youxiao and the others followed the sound to a courtyard, where they saw Xu Fuyuan and Wang Jizhong directing craftsmen to build something.
"The key is motivation." Wang Jizhong said with a bitter expression, "You can't keep going for long just by cranking with your hands and pedaling with your feet."
Xu Fuyuan nodded in agreement and said, "It's really tiring. I did it once and my legs were sore for several days."
Zhu Youxiao saw that there was another device next to it, which was driven by a belt and had a propeller-like object on it.
It should be a power device that can be installed on a hot air balloon to allow it to move in the air according to the control direction, right?
Zhu Youxiao felt that the goal could be achieved to some extent, but as Wang Jizhong and Xu Fuyuan said, it would be difficult to sustain it by human power.
Unfortunately, there was no immediate solution. Steam engines were nowhere to be found, let alone anything smaller.
"Brother Chen." Xu Fuyuan suddenly widened his eyes, and after being stunned, he looked surprised and ran over quickly.
Haha, I put on a fake beard, can you recognize it?
Zhu Youxiao quickly bowed and said with a smile, "Brother Xu, how are you?"
"I'm fine, I'm fine." Xu Fuyuan ran up to him, cupped his hands, and said with a hint of dissatisfaction: "Brother Chen, why are you so busy? It's been half a year since you came, right?"
Wang Jizhong also ran over, bowed and saluted, saying with a smile: "We all look forward to Brother Shen's guidance every day, but you are like a mysterious dragon that can only be seen from head to tail!"
Zhu Youxiao looked apologetic and explained, "I'm so busy with worldly affairs. I'm really sorry." After a pause, he added, "But I've been writing to you all the time. Seeing your letter is like seeing your face. Please forgive me."
"Just the letters..." Xu Fuyuan shook his head, looking confused and speechless.
Wang Jizhong gave a wry smile and said, "Just a few words of guidance won't get us the point. Experimenting by trial and error is a waste of time and energy!"
I want you to study and practice it yourself, that's the most impressive thing! Besides, I'm not a scientist, so I'm just describing it based on my impressions.
Zhu Youxiao smiled apologetically, turned around and walked to the belt-driven propeller, observed it for a moment, and said, "I think it would be more efficient if it were changed to a chain drive."
Xu Fuyuan and Wang Jizhong followed over. After hearing "Shen Lang's" instructions, they looked at each other and nodded at the same time.
Wang Jizhong said, "The chain drive is also under development and testing. If it succeeds, it should be used first on the bicycle that Brother Shen drew."
Bicycles are good. Although they don't have the cushioning of tires, they can greatly increase the speed of travel.
You should know that it was not until two hundred years later in history that wooden two-wheeled bicycles with handlebars appeared.
Moreover, this type of bicycle, which only moves forward by pedaling, still caused a sensation. Hundreds of them first appeared on the streets of Paris and were equipped to postmen.
Zhu Youxiao smiled and nodded, full of confidence in the advent of the bicycle.
Looking at the propeller, he stroked his chin and thought, thinking about the propeller of a boat. If the propeller was changed in direction, enlarged, and turned, could it become a helicopter?
