Bear kids are always a nuisance. As soon as he put on his clothes, Kiki was in a hurry to save the willow branch.

Anyway, the operation is like a tiger, and I don't know if I can save this willow branch. The whole family came home giggling, and Li Yunyun said happily, "Brother, you don't seem to know how to farm at all?"

"Alright, alright." It's still the old mother who feels sorry for her son, "We are already from the city, and it's not much use to learn this." Give me encouragement!"

Li Yuan smiled and asked, "Mom, do you have itchy hands when you see such a big piece of land in the garden?" Replace flowers and plants with fruits and vegetables?"

Zhang Zhen glanced at it and scolded with a smile: "Who will be rare in farming? How much is it involved? Don't think that I don't have knowledge, the garden is for urban greening, how can I farm?"

In the midst of laughter, Gu Yuqin said, "Yuanzi, you are busy outside every day, and you don't even bother to feed the three tigers, so it is possible to go farming?"

"What's impossible, get a fully automatic three-dimensional plant cultivation shed. With a few clicks of the mouse, you can automatically grow all kinds of crops."

"Brother, what's that? You're not going to brag again, are you?" Li Yunyun's eyes widened suddenly.

Li Yuan snorted disdainfully: "Hmph! Stupid girl who doesn't know anything. All of the next month's pocket money will be deducted."

"Don't!" Li Yunyun was anxious to hold Li Yuan and coquettishly, "I've been patting you on the back."

"Huh. You finally admit that you used to pat me on the back?"

"No! Elder brother~. Hey, hey......"

Li Yuanrou; Meat; Rubbing Li Yunyun's dog head: "I haven't seen it, have you? Your brother is high-tech as soon as he makes a move. It is to place a cultivation shed in the yard or room. It can be a single layer or it can be accumulated into multiple layers. Just plant crops in it."

Speaking of which, when I was on the forum in my last life, Li Yuan and a group of sand withering netizens really discussed this.

Wasn't that the ...... Closed community? This group of people is bored and rambling on the Internet, so they get to the point - how to eat and drink well!

But this is quite normal, the people of the big foodie empire, it's just this bite.

Of course, at that time, it was a blind chat. They slowly talked about a topic: what if the community is closed for a year and a half? Or even more in case of an alien invasion? Or Resident Evil?

So what to do when you run out of food? Is it possible to hit aliens to drop treasure chests? This seems to be a bit too humiliating, and it blinds our farming talent.

What if you have a nursery at home? You can plant whatever you want, and won't that become cool? Maybe a tomato can change a goddess...... Ahem!

"Huh?" The women were all taken aback, causing Kiki to giggle and laugh.

Zhang Zhen felt that she couldn't keep up with Li Yuan's train of thought: "Yuanyuan, are you going to plant at home? And what about the land?"

"Isn't there a nursery house? Each layer is filled with a thick layer of dirt. If the fertility is insufficient, you can also add chemical fertilizer and farm fertilizer. Think about it, if this cultivation shed occupies a penny, and it is piled up to five stories high, won't it have half an acre of land?"

Gu Yuqin and Li Yunyun were dumbfounded. Zhang Zhen has been completely smeared: "What about the sun? Don't you need light? Oh! And watering?"

"It's even simpler. Hang sun lamps on the top, and spray and drip irrigation at the bottom. Then make a circuit board and connect it to the computer, and you can realize fully automatic farming while lying down."

"You wait. How much does it cost?"

"Now that you're using this thing, do you care about water and electricity?" Li Yuan smiled and shook his head, "It's to use energy and water to solve the problem of planting plants in the family and even in the basement."

At that time, Li Yuan, they believed in vigorously producing miracles. As long as there is a large amount of external hydropower, it can be converted into plant growth. There is no need to think about the cost here. Of course, if there is no water or electricity at that time? Then no one else is to blame.

Zhang Zhen and the others were skeptical: "Really?"

"Of course it's true. Mom, you think of it as liking to grow flowers and plants. What's the point of spending some money for your hobby?"

Zhang Zhen thought about it and said, "Yuanyuan, my mother doesn't understand this. It's just that there are really people who raise flower seeds

Grass, buy these things?"

"Absolutely! The forest is big, and there are all kinds of birds." Li Yuan said with a smile, "There is a group of post-apocalyptic survival enthusiasts abroad, and they especially like this kind of strange things."

"Brother, what is a post-apocalyptic survival enthusiast?" Li Yunyun asked curiously.

"Hey! It's a group of rich people, who are well fed and supportive, and are preparing to survive in the last days every day. What if there is a natural disaster tomorrow? And ...... of social uncontrol, civil unrest, nuclear war, or banditry? They built a secret base. When something happens, the whole family hides in a secret base. They will also prepare a lot of food, drinking water, medicine, guns and ammunition, and even generators, ignition devices, etc., ...... what is the point of having an extra breeding shed?"

Gu Yuqin was also very curious: "Yuanzi, is there really such a person? Does that secret base work?"

"How do I know? I've never seen the end of the world before."

Li Yunyun couldn't help laughing: "They are just full of food."

Unexpectedly, my mother Zhang Zhen agreed: "Little four, you can't say that. I heard my ancestors say that when you flee from famine and war in a disaster year, it is no different from the end of the world. Fortunately, our mother and daughter are still rural residents. In case of an accident, the whole family can hide back in Fish Head Pass."

"That's it. Add an extra research project! Professor Shen of the Agricultural University borrowed it from me and asked the Agricultural University to come up with a design plan."

"Huh? Can Professor Shin do it there?"

"It's a piece of cake for them. I suspect they already have all the experimental data. It is nothing more than the design of a breeding shed, as well as an automatic breeding control system. It's not that difficult at all."

"How do you sell that?"

"It's simpler, it's on the U.S. website. Those who wish to take the bait, and then talk about the order. Mom, go and ask if Nongda is interested? They will provide technology, we will provide funding channels, we will account for 60% of the shares, 30% will go to the school, and 10% will go to Professor Shen."

"Is that ......?"

"Huh. Mom, to be honest, there will definitely be people who want this thing, but how many can it be sold? There won't be so many people who are fed, right? I'm not bragging, I don't like this kind of small business at all. If it weren't for the fact that I could barely call it high-tech, I wouldn't even bother to roll my eyelids. Where is it like some stupid woman? And call yourself a scientific researcher?"

"Nasty!" Gu Yuqin smiled and patted Li Yuan.

"Wow, wow, wow......" Qiqi also used his dog's momentum, and pounced on the bad baba who was bullying Ma Ma with his teeth and claws, and was immediately grabbed into Li Yuan's arms, "Wow...... Mama!"

"Don't bully my baby. Nasty!"

"Huh."

「……」

……

This whimsical cultivation shed project is the simplest in terms of technology.

There was no reason not to agree at the Agricultural University, and they didn't need their funds anyway, but Li Yuan supported another 100,000 yuan of scientific research funds.

Truth be told, these scientific research bills are equivalent to giving them away for nothing. There are no very special crops, they are all very home-cooked staple foods, fruits and vegetables. In the laboratory environment, I don't know how many times I have experimented. What temperature, humidity, growth cycle, etc., are all ripe.

The last is the frame design of the cultivation shed, which is nothing more than going to the university to catch a few strong men in their majors.

After the design was completed, Li Yuan found a few stage art students from Beiwu and drew a set of very beautiful on-site diagrams. Then I commissioned a global patent application and threw it on the homepage ad of the parallel line......

Li Yuan didn't take this seriously. Finley and Elna didn't take it seriously either. Isn't it just that the boss has an inexplicable new invention?

However, they still have a better name - the Tree of Life Survival Pod Type 1!

However, no one could have imagined that it was this inconspicuous advertisement, which seemed to be like a stone thrown into a dung pit, and immediately caused an uproar in the global technology community.

There is no doubt that this advertisement was written by a certain brother himself:

…… The recent failure of the Biosphere 2 experiment was not at all what I expected. A group of lay investors rejoiced in the success and completely violated it

The laws of scientific research. They haven't learned to walk yet, and they're ready to fly into the blue sky?

…… The aim of Biosphere 2's experiments is to complete an independent self-circulating ecosystem. Due to the large number of influencing factors and the complexity of interactions, it is almost impossible to complete the ecological self-circulation with the existing technology. It can only be replenished by external inputs, i.e. oxygen concentrators, water, etc. The only result - the experiment failed!

…… However, of all the impact factors, almost more than 90% of the required is the sun. At the end of the day, it's solar energy – energy! So can we change our thinking - not to demand ecological self-circulation? As long as enough energy is provided, the difficulty of maintaining the ecosystem drops directly by the same order of N as N? Or can the cost be reduced to a very cheap level?

…… The design of Biosphere 2 was particularly stupid. The tech tree in front is not finished, and you are ready to build a skyscraper on the beach?

…… Is it necessary to have such a sensationalist experimental project? I just don't know what to do!

…… The new generation of Tree of Life Survival Pod Type 1 was invented and designed according to this concept. This survival pod is composed of modules. It can be assembled independently by an adult man. The extreme planting of five modules can meet the food needs of a family of four.

…… A single pickup truck can transport one module. Can be placed in any environment, including but not limited to rooms, gardens, basements, ....... If you can do a good job of sheltering from the wind, you can even use it on the moon, Mars, and space station.

…… Fully automatic unmanned control. Commonly used crops are able to grow independently. It can be detached and combined, and can form a three-dimensional survival cabin, which can meet various needs.

…… The individual module costs $13,999. $35,999 for a five-piece module. Large quantities are preferred, and new products are on the market! A completely new experience for you......

All right! In the advertisement, it is stepping on a handful, stepping on Biosphere 2, and holding the Tree of Life Survival Module Type 1. For the sake of ...... Sell at a high price. Ahem!

Make money, don't chill! The cost is the number above, that is, the unit is replaced by a soft sister coin. And the selling price directly becomes the dollar.

Of course, these words are not entirely unreasonable.

For example: Musk's plan to immigrate to Mars later. In fact, the front-end technology tree is either a biosphere self-circulation system, or an energy ecological warehouse similar to the tree of life.

Otherwise, after the Mars base is established, how will the people on it survive? Is it just going to Mars to be lonely?

So, haven't heard of such a research project? That Martian settler...... Anyway, it's good to be happy!

Here, a brief introduction to Biosphere 2.

In a few decades, no one will have the impression of Biosphere 2, right?

But in the 80s and 90s of the last century, it was a global sensation. It is no less than the later Starship launches, Mars exploration, Tiangong and Chang'e programs, and so on.

Because Biosphere 1 is the Earth itself, it is named Biosphere 2. Initiated by several major conglomerates and a large number of wealthy people in the United States, the main investors are the Rockefeller family, the oil magnates.

Biosphere 2 was built in the desert north of Tucson, Arizona, USA. The eight-year construction site covers 12,000 square meters with a volume of 141,600 cubic meters, consisting of 80,000 white-painted steel beams and 6,000 pieces of glass at a cost of US$150 million.

It's amazing. At this time, the United States was indeed imposing and wealthy. You know, this is all private fundraising, and it is invested in scientific research projects that have no profits. In order to create an independent ecosystem, in order to immigrate to outer space?

After the completion of this miniature artificial ecological circulation system, in January 1991, eight scientists entered Biosphere 2. According to the plan, they will stay in it for two years, and will not be able to come out until the end of the experiment unless there is a serious accident.

For two years, apart from the supply of the first items, including seeds, everything else had to be solved by themselves. energy, derived from solar energy; oxygen, which is made by the plants they grow; Food, they themselves planted in it

Get; Meat and protein are taken from their chickens, ducks, pigs, and sheep. Even the temperature and climate inside are controlled by them and simulate the Earth's climate as much as possible. In short, they have to find a way to keep this little ecosystem in balance.

Unfortunately, the model of the Earth's biosphere is not so well modeled. Just a few months earlier, in June 1993, the Biosphere 2 experiment had failed.

There are many specific reasons for failure. There are many papers in this area, and those who are interested can take a look at it for themselves.

But no matter what. The failure of Biosphere 2 also caused a sensation around the world. The main emotion is still regret. It is too difficult to recreate the Earth's ecosystem, and there are many technical difficulties that cannot be overcome.

However, the scientific community around the world still praises those eight scientists, believing that they are still honorable despite their defeat. And in the crown jewel of science and technology, humanity is still out of reach......
