Global Wasteland: Unlimited Upgrades for Vaults

【Mining Difficulty】: Very Low

【Remaining reserves】: 26 tons

Click the function to switch the viewing angle, and it is a joy to play Sumo between the plane and 3D.

The sulfur mine was originally supposed to be a boxy cube stored underground, but after being mined, it has become an extremely irregular shape.

I don't know what disaster happened later, the current sulfur mine was compressed into a triangle.

The further down, the more reserves of sulfur ore.

"Hey, what are the resources I added to the random resource card just now?"

After searching around, Su Mo didn't find any good things added in the earthquake just now.

However, in the upper right corner, Su Mo saw a small trumpet-shaped thing.

Click to enter, and after three to five seconds, with a pleasant surprise, Su Mo directly returned to the initial interface, cut the plane to 3D and kept pulling down.

Sure enough, under the center of the underground shelter, there appeared a mysterious substance that seemed to be flowing slowly.

These substances looked invisible and colorless, only a little yellowish mixed in them, and because of the reason of flow, Sumo missed it when he checked it for the first time.

"What a strange feeling, is this water? Or gas?"

At the same time as the thought came into being, the big hand of the thought rubbed the wonderful substance in his hand and pinched it back and forth, and at the same time a message manifested.

[Geothermal resources (high temperature and high pressure steam) - level [-]]

[Mine Vein Status]: Complete body, not yet mined, in full bloom.

[Mining Value]: Two Stars (Peak: Two Stars)

[Special Ability]: I'm going to crack open (When the reserves are above 50%, the vein will recover 0.2% of the mineral reserves every natural day, and the mineral reserves will fall below 50%, and the ability will disappear)

【Mining Difficulty】: High

【Remaining reserves】: [-] tons

"Geothermal resources? Or high-temperature and high-pressure steam, why does it sound so familiar?"

Muttering this often-heard noun, Su Mo tried hard to recall where he had seen this thing before.

Tik Tok? station b?Tiger pounce?

Recalling a thing, Su Mo likes to recall from the very beginning, and bring out the rest of the memory by looking for the first memory point.

"It seems to be, thank you for the invitation? Yes! It's Zhihu!"

As soon as I thought of Zhihu, gradually, a series of information began to be connected in Su Mo's mind, and the flow of information also gushed out like a blowout.

When I saw the four words geothermal resources, it was not under the exclusive issue, but under the issue that everyone had already quarreled, someone put forward this argument.

Su Mo remembered the question at that time very vaguely, but he vaguely remembered that he was discussing the principles of nuclear power plants.

Nuclear power plants use nuclear energy to generate electricity.

The core equipment is a nuclear reactor, which heats water to generate steam and converts nuclear fission energy into heat energy.

The steam pressure drives the steam turbine to rotate, the heat energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, which converts the mechanical energy into electrical energy.

Pay attention to the official account: Book Friends Base Camp Follow to get cash and coins!

Therefore, such behavior of "burning boilers" will naturally not be accepted by some "mass" netizens.

At that time, some people were arguing below. Would the Tangtang nuclear power plant use such a "low" method to generate electricity?Isn't this funny?

Sure enough, not long after, a big guy posted a theory below, and proposed a power generation method that has been successfully explored so far, that is, geothermal resource power generation to support his statement.

After entering the 21st century, with the mining of coal and oil becoming more and more important, when technology is stuck in a bottleneck and cannot advance to "controllable nuclear fusion", how to use new recyclable resources has become the focus of exploration.

Among all resources, geothermal resources have naturally entered everyone's sight, and because of their high energy efficiency, they have gradually been promoted and developed rapidly.

In some areas with sufficient geothermal resources, heating has been fully utilized. Although the effect is not satisfactory, the advantage is that the cost is low.

As for geothermal power generation, heat energy must first be converted into kinetic energy, and then kinetic energy should be converted into electrical energy.

There are mainly three types of geothermal resources used for power generation, namely hydrothermal resources, ground pressure resources, and hot dry rock resources. The latter two have not improved even before crossing. Only the first type of hydrothermal resources has derived a series of Complete tech tree.

Underground hot water power generation must first separate the steam and water, and the water must be drained to make the steam enter the steam turbine to do work. This system is called a flash system.

Among them, the reason why geothermal steam power generation is the simplest is because geothermal steam is both a heat carrier and a working medium, and this step is omitted.

The well-known Yangbajing geothermal power station in Tibet has been in operation for more than 40 years, with an annual operation of more than 6000 hours and an average annual power generation of more than 1.2 million kWh.

fully proved the superiority of this resource.

"Geothermal resources are great, but at this stage it is too difficult to exploit them for power generation!" Looking greedily at the mischievous water vapor rushing back and forth in the hands of the mind, a sense of helplessness surged up. Somo's heart.

The deeper the ground, the higher the temperature, but the burial depth of the "heat source" is directly related to the development cost.

The key to utilizing geothermal technology is drilling and water injection, and drilling cost is an important constraint.

In addition to high technical requirements for drilling depth, terrain also has important constraints on the selection of well sites.

With the help of the system, it is not a problem to hit this place of geothermal steam, which is about five kilometers underground, but the cost of survival is not affordable at the current stage.

Of course, most people have no idea of ​​the cost of drilling a 5-kilometer well.

Huaxia has drilled 5000+ wells, which are currently only distributed in the northern part of Tarim, and the cost of a well is calculated in billions of dollars.

And this is due to the cost when there are thousands of meters thick salt rock formation in the local area. If the "butter soft salt rock" which is generally thousands of meters thick is replaced by hard rock, the cost will be doubled several times.

Stepping to the side of the generator set, Su Mo tried to call out the attributes of the generator. This time, there was a new upgrade direction for the generator set.

【Diesel generators】

Efficiency: 300kw (full load 300 degrees/h)

Fuel consumption: 230 grams per kWh (full load 82l/h)

Description: A diesel generator produced by Siemens Group in Wuxi, Jiangsu Province. The circuit function is intact and can be used normally at present, and the loss is almost negligible.

Upgrade Direction 1680: Replace the core components of the generator, enhance the power supply efficiency of the generator, reduce the power consumption of the generator, and need survival points ([-])

Upgrade direction 6500: Change the working method of the generator, change to biomass power generation, enhance conversion efficiency, reduce path loss, need survival points ([-])

Upgrade direction 36800: Open up five kilometers of underground motor wells, change the working method of the generator, change to a geothermal resource generator set, greatly improve the efficiency of the generator, and need survival points ([-])
