After water is converted into air internal energy. If it erupts from a vent.
Then the effect it produces is just the reverse thrust in the air. This is a huge waste of steam. It will be a huge waste of energy.
Everyone is in a dilemma on this issue. They don't have an open mind for the time being, and they are all thinking about how to use a vent to release a large amount of steam densely and generate greater reverse thrust.
For the time being, I have no ability to think of reusing steam in another form or device. The second energy conversion is to improve the power by leaps and bounds.
They just entered a misunderstanding and forgot that increasing steam emissions is to increase power. And mistakenly fell into the thought corner of 'increasing steam emissions and increasing reverse thrust can improve power'.
After Li Zhen's suggestion, everyone suddenly realized.
Divergent thinking was born from here.
Soon, someone asked: "Master Li. If the movement of the piston can be feasible, then another important problem has arisen."
Li Zhen's eyes lit up. Has anyone thought of it? "Please tell me."
"It is known that the container and the evacuation pipe are all closed spaces. Then as it continues to heat up, the air inside will continue to expand. If the blockage is movable, then it will only spray out. If the pipe is infinitely long, the piston can only spray infinitely. It Under the influence of pressure, it can only spray out, but cannot shrink back."
"My explanation may not be detailed and accurate, and it is difficult to explain what I mean exactly. What I want to say is... This is not true. Unless we set up extra-long pipes and extra-long transmission rods. As the steam erupts out, Pushing the piston to continuously spray out, prompting the connecting rod to continuously push outward. Then doesn't it require a wall behind it? Only with a wall can the transmission rod push the wall and move the car or boat forward? "
Everyone was a little confused, but Li Zhen actually understood.
To be honest, he was temporarily stuck on this problem.
He understood the principle of a steam engine, but he had never seen a steam engine. He only vaguely remembered hearing someone describe it.
He has also been stuck on this problem for several days, and this problem is. The movement of the piston must be able to push it out, then withdraw it, push it out again, and withdraw it again. Only when it moves back and forth can it be called sustained power.
However, the internal energy of the air in a closed space will continue to expand, and the piston can only be sprayed out if it is continuously squeezed. But can't shrink back. This is a big problem.
There must be a solution. But Li Zhen didn't think about it for the time being. I feel like I should have thought of it almost, but I just can’t grasp that point.
Soon, other students also reacted. I found a pipe and inserted a branch into the pipe: "If the pushing force of my hand represents the pushing force of the steam. Then my hand inserted the branch into the pipe, and I could only insert it. , but can't pull it out... Because if my hand is powered by steam, the steam will not shrink. In this way, a reciprocating cycle cannot be achieved, and a reciprocating cycle cannot be achieved. This can only generate instantaneous power, but sustained force is not established. "
This classmate used branches and pipes to represent steam and pistons. Everyone immediately understood what the problem was.
Steam can only push the piston forward, but because of its constant expansion, it cannot push back. Repeated cycles cannot be achieved. This is contrary to the principle.
The piston requires at least two actions to complete the conversion of mechanical capabilities. These two movements are to push forward and retract. Push forward again, then retract.
But students from Kyushu Institute of Physics finally discovered that the problem of steam engines is as difficult as a chasm. It is simply a chasm. All they could think of was that this piston could only make one move... and that was to move forward.
"We have to cross the river by feeling the stones, solve problems when we encounter them. Everyone must have divergent thinking."
Li Zhen said loudly.
Everyone returned to their seats thoughtfully and took out their notebooks to write and record.
Then the design started again.
The road to steam engines is long and not that simple.
Its principle is not complicated, but there are too many problems to be solved.
Li Zhen walked out of the laboratory and strolled through the streets of Quancheng County. I have been feeling a bit bored after staying in the laboratory for this period of time. Going out to relax and relax my brain is more effective than working behind closed doors, right
"I've been in Quancheng County for so long, but I really haven't taken a good look around the main city of Dongzhou."
Qi Lengzi followed behind and said with a silly smile: "As the saying goes, if you want to understand the customs and customs of a place, you must first understand the women of this place."
Li Zhen rolled his eyes: "Don't expect me to take you to the brothel."
Qi Lengzi said sullenly: "I won't go to that kind of place. I just... Do you have any female classmates you can introduce to me?"
Li Zhen smiled, and his opinion of Qi Lunzi improved to another dimension. This guy's hands were quite long.
But you don't need to think about it to know that there will definitely be no female classmates in Fuxing University who can fall in love with him. This has nothing to do with charisma.
Those who entered Fuxing University all considered themselves scholars and intellectuals. They all look down on illiterates. Even if Qi Lengzi had unrivaled martial arts skills and looked like Pan An, he would not be recognized by those female intellectuals at all.
When it comes to their views on marriage, college students in Kyushu are very stubborn and conservative. It is said that it is free to marry and fall in love, but in fact it is not free either...
Qi Lengzi followed behind and kept saying, "It's true. I like a female classmate. Can you introduce me to her?"
Li Zhen asked curiously: "Which female classmate?"
"A girl from the Physics Department who is in her fifth year has now joined your Kyushu Institute of Physics. You and she have been meeting each other for the whole day. Please introduce her to me."
"There are many girls in the fifth year, and there are also many girls in my Kyushu Institute of Physics. How do I know which one you are talking about?"
"That's it... that... oops."
Qi Lengzi suddenly became arrogant. The burly man blushed and said awkwardly: "That one is quite tall and likes to wear thick glasses."
Li Zhen thought for a while and exclaimed: "You are not talking about Hou Qiang, are you?"
"Well... that's her."
Li Zhen was shocked. He originally thought that Qi Lengzi liked the weak and coquettish style of Jiangnan women, but he didn't expect that he actually liked this tone.
Hou Qiang, although her name is Qiangwei Qiang. But the first thing I think of when I read it is 'Hou Qiang', a very masculine-sounding name.
In fact, this girl is very manly, a head taller than Li Zhen. About 1.85 meters tall. A tiger's back and a bear's waist. She likes to have short hair that doesn't even cover her eyebrows, and wears a pair of glasses with lenses as thick as the bottom of a glass bottle.
Qi Lengzi said shyly: "Her hometown is Xizhou. I like that figure very much, very healthy. And she also wears glasses, and she looks like a scholar at first glance. My biggest dream in this life is to marry an intellectual as my wife. That wears If you wear glasses, others will know you are an intellectual."
Li Zhen looked at Qi Lengzi's muscular figure with a strange look on his face, and murmured: "You are indeed a good match..."
