This causes the force that increases the linear velocity of the car to be perpendicular to the cable, which means that this force will be the pressure exerted on the cable.

During the upward running of the car, the cable has been giving him a pressure parallel to the ground, making it continuously increase the line speed.

The kinetic energy provided by the cable is obtained at the expense of the speed and height of the synchronous orbital station. In this way, it is difficult for the synchronous orbital station to remain stationary.

Therefore, the synchronous orbit station itself needs to carry fuel, or related propulsion devices, to continuously counteract this force, so as to maintain its height and not be dragged down.

Since the fuel needs to be replenished regularly, and the process of transporting the fuel also consumes a huge amount of energy, a better method is to use the car itself to carry the fuel to provide power.

Thanks to today's breakthroughs in battery technology, a battery weighing 300 kilograms can already meet the consumption of a space elevator at full power for a month.

Therefore, the consumption of related fuel and electric energy is not very short, but if the scale of the space elevator is expanded in the future, and the construction of a ring-shaped residential area outside the atmosphere surrounding the entire earth is not something that can be solved by battery power. .

The second method is similar to a conventional elevator, through the weight at the other end, or another car can be lowered to increase its load.

This method does not require the car to provide tangential kinetic energy for itself, and directly descends from the car on the other side to provide kinetic energy for itself.

This principle is similar to that of an elevator, but this method strictly requires weight balance during each lift, and considering various resistances, the upper and lower cars should still carry air jets to offset the lost mechanical energy.

"Actually, master, allow me to make some comments on this heaven-defying project of the space elevator." At this moment, Ye Fan's smart glasses sounded the voice of origin.

The origin itself is an intelligent life. From the moment it was designed and born by Ye Fan, it has been constantly absorbing external knowledge and growing.

However, limited by the computing power of a thousand quantum computers, the growth of Origin cannot be said to be rapid, but it is also very terrifying.

When Ye Fan asked Origin to evaluate the space elevator project, the conclusion of the big data deduction that Origin has gone through is that the space elevator project itself is at the - (minus) SSSS level.

That is to say, the priority of this project can be ranked behind any existing plan and project.

"Well, what do you want to say?" Ye Fan nodded and asked.

"The budget of the space elevator is 3 trillion yuan, and it is a conservative estimate. Such a high price is definitely beyond the limit that our Datang Technology can bear, and this is still a meaningless project."

Speaking of which, the origin directly displayed a report made by itself on the smart glasses.

[Questions about the feasibility and cost-effectiveness of space elevators] Love novels

Master, let us jump out and think about the problem from another angle: What more valuable space projects can we do with the funds used to build space elevators?

The synchronous orbit is as high as 36,000 kilometers, which is more than 100 times the height of the International Space Station and three times the diameter of the earth. Regardless of the difficulty of construction and construction, let's simply estimate the amount of work.

Assuming that the carbon nanotube cable is one meter and one ton, not counting the counterweight or construction equipment, the rope alone has a weight of 36 million tons.

This is equivalent to 360 100,000-ton USS Ford aircraft carriers, which is nearly half the tonnage and weight of the floating city in our "South Tianmen" plan, and nearly 1.80 200,000-ton space battleships" The tonnage of the Jade Emperor-class space battleship.

Master, please close your eyes at this time and imagine, if you have a fleet of 180 "Jade Emperor" space battleships in space, this star fleet is arranged in a matrix of 19*19 dots, The huge hulls are 300 meters apart, which can form a black and dense 3km*3km giant steel blanket.

Your commander of the Fleet Empire is standing on the summit of the cosmic city planned by the "Nantianmen" in the cosmic battleship array, seeing the giant black steel ships full of lights around you, extending to the four directions of the city and into the depths of the universe, You will realize that you are no longer a fleet commander, but the head of an empire, and you have formed an interstellar civilization in space.

At this time, master, what do you plan to command this interstellar civilization to do?

Obviously, master, as the head of state, the soul and leader of the human alliance, you will not use such a huge fleet to build a space elevator, but will drive a team to mine on the asteroid, and some of them will start Go to Titan to collect methane, and part of it will go to the perihelion orbit to deploy a reflective array to build a new space city.

In other words, these 180 super space fleets can already form a self-sustaining, growing and multiplying industrial system, and they no longer need to keep in touch with the earth.

For example, after discovering the New World hundreds of years ago, the Spaniards thought that dozens of cities had to be moved to the Americas to support the operation of the colony.

But in reality, it only took a few thousand colonists to immigrate to the Americas, and these people could make tools, build cities, and have children in the New World.

And two hundred years later, Amejian has grown into a giant that is hundreds of times stronger than Spain. During this period, there is basically no need for large-scale and continuous transportation support.

Like a new continent full of forests, the resources in space can be tens of thousands and hundreds of thousands of times more than those on the earth.

The earth's resources are very poor, just like the minerals related to upgrading the ion engine need to be collected from various asteroids in the solar system.

In space, the transportation of objects mainly relies on inertia, and a gravitational slingshot can also be used to borrow force. This force is much less labor-saving than transporting resources from the ground to space.

In space, the density of sunlight energy is twice that of the earth, and the closer to the sun, the energy can be said to be endless.

In the asteroid belt, on the moons of Jupiter and Saturn, there is no shortage of mineral resources, let alone carbon and water resources.

However, there is no output during the construction of the space elevator. If the cost is not shared equally by the country, there is no way to complete the construction at one time with our ability.

With the industrial level of our Datang Heavy Industry, the cost of building a "Yuhuang-class" space battleship is 10 billion, and the total cost of 180 warships is only 1.8 trillion.
