Let's talk about the structure of this eco-boat with a unique design style.

If you do not include the light booster rocket launcher suspended from the bottom of the ship, the hull with a total height of 10 meters is divided into five layers.

Of the two floors submerged under the water, the lowest layer is equipped with the nuclear fuel tank, engine and power cycle drive unit of the eco-boat, which is called the basic cabin.

How inconceivable and strange it is to propel a ship with a displacement of less than 5,000 tons into the Pacific Ocean with powerful nuclear power, and anyone who hears it will scoff at it, thinking that it is tantamount to feeding an entire banana to ants.

But if it is stated in advance that the designers' design was not intended to create an enclosed cruise ship that could walk in the sea, but rather to draw the conclusion based on precise calculations that there would be sufficient fuel for the future light-speed fusion spacecraft that would sail into space, the ridicule would have been replaced by amazement. You must know that for mankind, they are about to enter the glorious 23rd century, but the fuel used in spacecraft is still liquid hydrogen and liquid oxygen, which is undoubtedly a heart disease of aerospace scientists.

The engine of the eco-boat is connected to a miniature nuclear power generation device. The plant covers less than 100 square meters but has a reactor consisting of complete fuel assemblies with a rated capacity of 1,000 megawatts.

At present, the nuclear generator set is in a state of stagnation, and only runs at low power once a year, so as to reserve enough power for the next year for the eco-boat, and connect the waste treatment and heat treatment pipelines with the ship's air filtration system, wastewater treatment system, ventilation and temperature and humidity control system, so as to ensure that the lone ship floating on the sea has maintained the ecological cycle mode of the spacecraft's carrying module.

The second underwater level is occupied entirely by a green plantation, which is called the Subsistence Cabin. It is a plantation that only needs to supply one person with daily necessities, so although the number of crops planted is small and the total yield is low, there are many kinds of plants. For example, in addition to food crops, fruits and vegetables, a flower garden has been created in the area to the east where direct sunlight can be reached. There are more than 20 kinds of flowers and plants planted in the flower garden, one of which is a strange plant that can produce seven color buds on the same plant after Haige got on the ship and successfully grafted with multi-headed chrysanthemum and hyacinth, and they called it the colorful enchantress.

But anything that grows out of the soil can basically contribute to the eco-boat. For example, after the wheat is ripe, in addition to grinding the ears of wheat into flour and eating, you can also use wheat mango and wheat bran to raise sea pigs and fish. The sea pig fish is a deep-sea mammal with a pig's nose, which not only resembles a pig, but also provides tender meat similar to pork, and the foul feces it excretes are excellent quality fertilizers, and the soil mixed with the feces is always particularly fertile.

The slightest movement of the nuclear generator set is enough to drive the oxygen supply system of the entire ship, but in addition to opening the fairing directly to feel the salty smell of the sea, Haige also likes to collect fresh air from the plantation.

The chloroplasts of a large number of plants photosynthesize under the irradiation of simulated sunlight, and the oxygen produced is transmitted to the aquatic living layer of the eco-boat through the oxygen inhalation tube, and when Haige lies by the glass porthole with his eyes closed, it is easy to forget that he is in an uninhabited sea. He seemed to be on land, walking along a country road, and not far away the farm's houses could be seen on the green green meadow, and the cows were mooing from time to time on the farm, and the primitive and quaint rural beauty made him feel refreshed.

Entering and exiting the basic cabin from the living data compartment requires the use of complex fingerprint and iris dual authentication methods. Once verified, a metal door will be opened on the floor camouflaged with plants for one person only.

From the living materials cabin to the first layer of the water, that is, the welcome cabin, there are not only electronically controlled elevators, but also a spiral iron ladder covered with ivy, and Hai Ge likes to go up from the spiral ladder.

The galley and living room on the eco-boat are on the first floor of the welcome cabin, and there is a reading room behind the living room. The three bulkheads of the reading room are lined with tall bookshelves with all kinds of books related to the universe and navigation, and Haige has read almost all of them in ten years.

At the beginning, any book was as profound as a book for him, but with a nanobot that was more powerful than an encyclopedia, he could always get guidance in time, and now he is familiar with the knowledge in the book, and he can come to it at his fingertips. Success once praised him, even if he was a master's degree in aerospace at the university, the level was not as good as him.

Ascend the spiral staircase to the fourth floor, where is the leisure cabin. Hai Ge's bedrooms and open-air entertainment area are all here, and of course there is another core feature of the eco-boat, the cockpit.

The lounge cabin goes further up to the top deck, which is called the freeboard. The only facility there is the watchtower, which is surrounded by six huge brown floor-to-ceiling glasses in a conical shape, and the radar detectors at the top of the tower flash red lights from time to time, and anyone who looks from a distance might mistake it for a lighthouse.

The watchtower is no less important than the cockpit and the base cabin on the Huoyiren, in fact, it plays the function of a "floor-to-ceiling telescope", that is, the six-sided glass is six lenses with anti-reflective film, which not only has the function of expanding the field of vision, but also connects with the computer system. The essential difference between the whole watchtower and the traditional telescope is that the traditional telescope has to be held by people, and the floor-to-ceiling telescope is that it carries people, and even actively guides people to look in the right direction through the full-field operation system.

Because all the glass acts as a telescope, no matter which sea area the observer wants to study, he can easily find and confirm its latitude and longitude, and then present the nautical chart of that area on the glass, which is so clear that he can even see a water plant floating on the surface of the sea, or a small pebble on land.

Although the watchtower is considered the fifth level of the Hoiren to Haige, it can be folded and shrunk. The six sides of glass could be stacked on top of each other, and the computer control panel sank into the storage space in the gap in the deck, making it look indistinguishable from the deck, so that even if the Hoi encountered an intruder, they would not be able to find the watchtower.

The logbook of the 10-year voyage, as well as a navigation manual that accurately maps the structure of the Hoiren and explains how to convert it between a spacecraft and a nuclear-powered eco-boat, are placed in the watchtower's computer system.

Above the watchtower, there is not the sky of the earth, but a thick film-type infrared fairing, which is a key part of ensuring that the fire is fully enclosed.

People's understanding of the material "membrane" is generally believed to be broken as soon as it is stabbed, and it cannot withstand the fire of the knife.

However, although the fairing is a membrane, it is made of a very special material, called oxygen-free plant fiber. Glass or ceramics can be shattered, wood can be burned, metal can be cut, any hardness of the material can be destroyed, and even if it survives, the seal will break if a missile flies. And the super-flexible membrane is not even afraid of missiles.

Weedel once told Haige that this kind of oxygen-free plant does not exist on the earth, and the fibers extracted from their leaves are fire-resistant and acid-resistant, and even if they are cut or pierced with the sharpest sword on the earth after making a film, they should not want to make a small cut in the membrane.

The most bizarre thing is that if it is really attacked by a weapon such as a missile, the super-elastic membrane can be intact, it will only deform for a short time, and as long as the attack stops, it will quickly return to its original state.

Hiding in this layer of plant fiber membrane that earthlings can never destroy, the Huoyi has truly become a sea fortress with 100% sealing performance.
