Saturday, March 24th, morning, harbor vice-center.

While Mori and his party of thirteen were busy queuing up at the harbor, Tachibana Maya left the opening ceremony after speaking at the opening ceremony and entered the Tojin Odaiba Hotel, took the elevator to the top floor and went up through the rooftop stairs guarded by bodyguards, and met Miyamoto Ichiro and Miyamoto Miko in the temporary house on the rooftop, Belinda, Olivia, Annie, Enoch, and Hikihime, Asai Kao, Fujii Takako, and Misa Horiuchi, everyone was drinking drinks and watching TV news around the table.

After the greeting, Tachibana Maya sat down, and Miyamoto Miko brought a cup of tea, "The manuscript is good." ”

"Thank you, ma'am. Tachibana laughed.

"Miko, I just did the math, but you made a big deal. Olivia laughed.

"How?" Enoch asked.

"The average land price here used to be about 10,000 yen per square meter, but now it's not much than 10 times. Olivia laughed.

"What's the matter," Miyamoto said, "there are more than 500 hectares here, and the tenfold increase is only more than 500 billion yen, and when I bought it, I spent 1300 billion yen, contributed 300 billion yen to the exposition fund, plus construction costs and other expenses, it cost nearly 2 trillion yen, and it is still too early to make a profit." ”

"I didn't say you're profitable," Olivia laughed, "and it's not your way of calculating it, you're buying a permanent land use right, and you don't have to pay taxes for fifty years; judging by today's crowds, you won't lose much in the end from the fair's ticket revenue, and these tourists will bring you a lot of money in terms of transportation, hotels, retail, etc." You can recoup most of the cost anyway, and then you can develop it casually. ”

"Forget it, I can't tell this thing. Miyako Miyamoto shook her head and said.

Olivia laughed, "Anyway, you have to admit that this fair has made you a fortune." ”

"There is no doubt about that. Enoch laughed.

"Well, I'll admit it. Miyamoto Miko laughed.

Enoch asked, "By the way, I have a question, Belinda, Olivia, Annie, why aren't you all exhibiting?"

"Are you sarcastic about us?" Belinda asked angrily.

"Belinda's steel, Olivia's traffic, and my oil," Anne laughs, "and we're inherently opposed to green, and exhibiting in the fair is only questionable." ”

Miyamoto Miko said: "That's right, but the factory is not environmentally friendly, and the state will not be soft on fines, so we still have to do more research." ”

"Of course, I just don't think it's working. "Only when the earth's vegetation coverage reaches a certain level can we effectively curb global warming." ”

"As far as I know, there are already a lot of people in Brazil who are ready to develop forests in the Amazon basin to create pastures because of mad cow disease," Anne said. ”

"This kind of thing has been happening for a long time, and the Brazilian government can't stop it. Enoch said.

At this time, a heavy shield helicopter flew over, and Miyamoto Miko smiled: "Let's go, I'll take you to see my ranch." ”

Moments later, the Heavy Shield helicopter landed on the rooftop, and Miyamoto Miyako and her party boarded the bus that drove out of the cabin. ……

Near the new town of Chiba, Chiba Prefecture, the experimental area of the Inhan Vertical Farm Building.

The heavy shield helicopter stopped on the apron of a building and released the bus, Miyamoto Miko and his party got off the bus, Miyamoto Miyako took Miyamoto Ichiro and walked to the railing first, looked outside and smiled: "The vertical farm building is the behemoth in front of you." ”

"Well," Olivia laughed, "I think our money habits are all infected by you. ”

"Definitely, yes. Belinda laughed.

"There is no way to build like this, and the operating cost is high if it is small. Miyamoto said, "For example, farming, filtration of gas emissions, etc. ”

"How big is that?" asked Anne.

"The vertical farm covers an area of about two square kilometers, about 55 meters high, and has 12 floors inside, each with about a meter of dirt deep, which was dug up during the construction of the subway and the Doomsday Building. "The surrounding buildings are biogas systems, water treatment systems, meat processing plants, dairy processing plants, feed processing plants, and warehouses. The place where we are standing now is the roof of the Experimental Center Building, which is about 120 meters high and covers an area of about six hectares including the skirt, with a computer center, a biological research center, a medical breeding center, a hospital, a convenience store, a restaurant, and an apartment. ”

Enoch asked, "I have a question, such a big building, not to mention the lighting inside, definitely not, but it doesn't matter, but what about ventilation?"

Misa Horiuchi said, "It's by the fan, and the rooftop is full of that thing." ”

"I'm interested in computer centers. Belinda asked, "Precision agriculture, huh?"

"Yes, the computer center will collect and monitor the data of the vertical experimental farm, and monitor the conditions in the vertical farm building, the temperature, humidity, oxygen content of each floor, the body temperature, weight, eating, excretion and other states of each cow, and the temperature and growth of each crop. "We manage ventilation according to the respiration and oxygen content of animals and plants, and adjust the temperature, humidity, and brightness of lights according to the growth of livestock and crops." ”

"It's a good system. Olivia said.

"According to the calculation of 100 beef cattle in 600 square meters, 2 million square meters in 2 square kilometers can accommodate 300,000 beef cattle. Anne said.

"Can you raise so much?" Enoch was surprised, "The twelfth floor is three million and six million, and the vertical farm is really provincial." ”

Misa Horiuchi smiled: "How can there be so many, the houses are trampled." ”

Asamika smiled: "That's right, in that case, the cow dung can be piled up higher than the mountain every day." ”

"Now there are 10,000 beef cattle on the first floor, and the eleven floors upstairs are full of feed. The plan is to raise 200,000 beef cattle on the first floor, and then use cow dung to raise some earthworms and fungi, etc., and the upper ten floors are used to grow feed, and then add salt, minerals, etc., enough for the cattle downstairs to eat. The first floor is used to grow grain, vegetables and fruits, on the one hand, for research, on the other hand, for the people in the experimental area to eat, and the eleventh floor upstairs raises some chickens. ”

"Self-sufficient. Enoch said.

"A cow can produce five to six tonnes of cow manure a year, and a biogas system can process 4,000 tonnes of cow manure and other organic matter a day. "The electricity generated is enough for more than 20,000 households, and it can't be used here, and there will be a lot of revenue after it is connected to the grid." ”

"Don't forget it, this farm is not worth building for a landlord like you. "Japan has less than 50,000 square kilometers of land, and 20 square kilometers is 1 in 2,500." ”

"How much does it cost?" asked Olivia.

"There are fewer people working in agriculture in our country, and it makes no sense to throw away other systems and build a small vertical farm in units of 1,000 square meters. Miyamoto said. "And I, not counting the cost of system research and development, and the cost of soil between floors, the construction cost is about one billion dollars, if someone else estimates that the cost cannot be recovered, and my catering industry can consume these beef, but this is the case, the preliminary estimate is that it will take at least ten years to recover the construction cost. ”

"Forget it, then. Olivia said.

"Let's go, I'll take you for a tour. Miyamoto said. ……
