"Don't be frustrated, it's pretty good that you can do this." Lawrence and Viscount Surrey comforted at the same time looking at the engineer who was now a little frustrated after talking about the shortcomings of briquettes.

"It's a good idea to have this idea of ​​turning waste into treasure, and putting them into practice is a very, very powerful thing." Lawrence said to the engineer.

"Seriously, it can be said that you have this kind of thinking is very pioneering, but also very valuable" Lawrence clapped his hands after throwing the briquettes into the coal pile nearby.

"On the basis of your invention, I have come up with a good solution that can solve most of the defects in your current invention."

After seeing these briquettes, Lawrence immediately thought of something like briquettes. Although in his previous life as a post-90s living in a city, he used heating instead of briquettes in his home, but this kind of thing is not uncommon for him.

Especially after he went to college, because he read a lot of novels about crossing and all used briquettes as the starting point for entrepreneurship, so he also checked some knowledge about briquettes production for this purpose.

Although he can't understand the pictures of the machines that make briquettes because of his professionalism, the small machines used to make briquettes by hand can still be understood and written down for simple reasons.

So Lawrence soon took out a pen and drew a machine for making briquettes by hand on a piece of paper, and then handed it to the engineer.

"Is this a tool to change the shape of briquettes?" As a professionally educated engineer, he quickly saw the structure and usage of this small tool.

"Yes, I think your idea should be correct. However, such a loose but solid existence is naturally not so good when it is burned, and it is easy to fall into a ball after it is burned." Lawrence pointed to the pile. Said the pile of briquettes in the corner of the room.

"However, if it is pressed into such a hollow shape, it will not be easy to have the problem of insufficient firepower or incomplete combustion and smell of burning briquettes with a passage that allows the flame to pass through." Lawrence pointed to the drawing. The three views of briquettes said.

"More importantly, it is different from the shaken briquettes. This kind of briquettes has a squeezing process during the manufacturing process. This way, the problem of this artificial fuel being burned and scattered all over the ground can be avoided. ."

Although there are not many machines in this coal mine now, there are not many kinds of tools. So naturally there is a small workshop for repairing and processing some simple tools or tool parts.

For such a professional small-scale mechanical manufacturing plant, the simple briquette making tools on Lawrence's drawings are very simple for them to make, as long as they have raw materials, they can be easily manufactured.

So after only waiting for less than half an hour, a few workers wearing leather aprons and goggles gave Lawrence and the others a few samples, and then Lawrence and the others went to the factory producing briquettes to start experimenting with this new tool. .

After making the briquettes, they immediately dried the briquettes with magic, and burned them on a table.

"There is still some smell, but ordinary people should not be able to smell it." Viscount Surrey said after sniffing.

As an extraordinary person, he is naturally much better than ordinary people in sense of smell. But even so, he could only smell a very faint scent of soot. This also means that the briquettes have solved the original problem of peculiar smell when burning briquettes.

Over time, the briquettes changed from black to khaki. But unlike before, the whole briquette combustion process did not have the problem of burning and dispersing like briquettes burning.

As a result, the original coal ash that was flying around during incineration was naturally less, and the surrounding area was much cleaner.

"In addition to burning this kind of briquettes as ordinary coals, you can also use some matching coal stoves." With that, Lawrence drew a few sketches of the stove in his rural home when he was burning briquettes just now.

In these pictures, in addition to a pipe for the exhaust gas to the outdoors, the stove also has a vent cover for different container sizes and a simple adjustment of the amount of air entering the furnace, as well as a kettle attached to the stove.

"I have checked the information before. Almost all cities in this generation rely on geothermal to maintain their temperature." Lawrence said, pointing to the briquettes he drew.

"But these cities alone cannot sustain the people's requirements for opening up on this island, or after occupying the key points with geothermal energy in the early days, the intelligent race will inevitably need to march on the desolate and cold plains in order to survive. ."

"And this coal stove of mine can solve part of the heating problem. At least those solid and heavy-walled rooms on the wasteland, if equipped with such a coal stove, at least the space utilization rate is much better than the fireplace. ."

"You're right." Viscount Surrey said after taking a look at the size of the ventilation ducts marked on the picture.

"At least compared with this thing, the chimney of the fireplace is really too big. Not only is it easy to reduce the temperature, but it is also easy to be attacked by some cunning monsters as a weak point of the building."

"It's not only that." Lawrence clicked on the stove on the drawing and said. "I remember that the simple shelters in the wild are often very small, so they just built a fireplace in the lobby on the first floor. Although everyone can't freeze it like that, it naturally doesn't get much warmer."

"With this kind of coal stove, they can have one such stove in each house. Compared with the overall fireplace, this kind of distributed coal stove is more flexible."

"At the same time, this new type of heating equipment is obviously more advantageous than those old-fashioned fireplaces in terms of volume and fuel consumption."

"Yes, it turns out that those old fireplaces immediately occupied a large part of the first floor of the previous room. In addition to reducing the space in the room, it is also very unfavorable for arranging defenses on the first floor during battle."

Viscount Surrey recalled his previous impressions of visiting the scattered settlements. "If those fireplaces are knocked out, it should be able to reduce the original shooting blind spots on the building, and at the same time, it can place more objects on the first floor."

"More than that, I think you are also trying to build some micro-visions to grow vegetables around, right?" Lawrence remembered at this time some buildings that were obviously used for agricultural production in the periphery of the city.

"Yes, always relying on importing edible vegetables is always not a solution. UU reading www.uukanshu.com, but just eating a few kinds of fish and boiling moss to supplement the various nutrients needed by the human body is not an option at all. Can't bear it." Viscount Surrey looked helpless.

"In fact, the Institute of Medicine under my hand is extracting the nutrients needed by the human body and making them into some medicines. Just take one pill when needed." After watching the few people present staring at them, Lawrence shrugged.

"Of course, those things can only be used as emergency supplies, but they should taste better than drinking moss soup."

"Unless I have to, I will never take the initiative to take medicine." Viscount Surrey smiled and shook his head, then asked Lawrence. "By the way, did you ask about the reasons for the vegetable cultivation?

"Because this coal stove can be used to build a greenhouse. "Lawrence said.

"Compared with the brazier, this thing is not easy to poison the workers in the greenhouse because of the vents, and compared with the fireplace, this thing is obviously lower in cost."

"You're right, I think this thing does need to be ordered." Viscount Surrey nodded and said in agreement.
