Chapter 433 Geothermal Energy

Then Liu Qi excitedly said before Liu Xiu could speak:

"And the most crucial thing is that once the mantle and core of Wandering Blue Star cool down, my planetary engine enhancement plan can be implemented. At that time, under the powerful thrust, the maneuverability of Wandering Blue Star will reach a new level, instead of being as slow as it is now! Only in this way can Wandering Blue Star truly become a war star."

In response to Liu Qi's excited expression, Liu Xiu waved his hands and said:

"Don't get too excited. I still need to take a look at your plan report and see if it is feasible before I decide whether your plan can be implemented!"

After saying that, Liu Xiu no longer paid attention to Liu Qi, but instead picked up the thick plan report that Liu Qi had placed on the table.

When Liu Xiu opened the first page of Liu Qi's plan report, he saw a new type of pipe designed by Liu Qi, and Liu Qi named this pipe geothermal exchange tube.

The structure of this geothermal heat exchange tube is also very simple. It is divided into two layers, inner and outer layers, and is composed of two tubes of different diameters put together.

The inner pipe is the water inlet, while the outer pipe is the water outlet, and the bottom of the pipe is where the inner and outer pipes are connected.

When working, this pipe is inserted into the hot rock or magma below.

Then cold water is injected into the inner pipe. When the water in the inner pipe reaches the bottom of the pipe, it will flow back to the outer pipe through the connection of the outer casing. However, when returning, since the outer pipe is connected to the high-temperature rock or magma, it will naturally absorb its heat.

Therefore, after the originally high-pressure water absorbs a large amount of heat and returns, it naturally turns into high-pressure and high-temperature water vapor. The high-pressure steam converted from geothermal energy is then used to drive steam turbines to generate electricity.

The geothermal technology Liu Qi used was not particularly advanced, because the technology of using geothermal energy to generate electricity had already existed on the Wandering Blue Planet in the 20th century.

Humans have been using geothermal energy for a long time, such as using hot springs for bathing, medical treatment, using underground hot water for heating, building greenhouses for crops, aquaculture, and drying grains, etc. However, the real understanding of geothermal resources and their large-scale development and utilization did not begin until the mid-twentieth century.

Most of the geothermal energy comes from the non-renewable thermal energy deep in the wandering blue planet, which comes from the decay of the molten magma and radioactive substances of the wandering blue planet.

A small amount of energy comes from the sun, accounting for about five percent of the total geothermal energy, and most of the surface geothermal energy comes from the sun.

Of course, although geothermal energy is a non-renewable energy, due to its huge thermal energy, it is not an easy task to consume the geothermal energy in a short period of time, turn the mantle magma of the wandering blue planet into rock, and cool the liquid metal at the core into a solid state.

Ordinary natural geothermal energy is the result of deep circulation of groundwater and the intrusion of magma from great depths into the earth's crust, which brings heat from deep underground to near the surface.

Its reserves are much greater than the total amount of energy used by humans wandering the Blue Planet, and most of it is concentrated along the edges of tectonic plates, an area prone to volcanoes and earthquakes.

But how to utilize this huge potential energy!

However, this problem was solved by Prince Piero Ginoni Conti of Italy in 1904, who first used natural geothermal steam to generate electricity in Larderero.

Geothermal power generation uses hydraulic or explosive fracturing methods to inject water into rock formations to generate high-temperature steam, which is then pumped out of the ground to drive turbines to rotate and generate electricity. In this process, some of the unused water vapor or exhaust gas is processed by condensers and converted back into water and sent back underground, and the cycle repeats.

Of course, this is just the previous geothermal treatment method. Now Liu Qi's geothermal treatment method is to directly drill holes in the geothermal crust, and then drill all the way to the area close to the magma, and then put in a large number of geothermal pipes, so that a large amount of high-temperature and high-pressure steam can be collected. Of course, these high-temperature and high-pressure steam are naturally the best kinetic energy to drive the steam turbine to rotate.

Of course, if geothermal pipes are used on a large scale according to Liu Qi's plan, a large amount of high-temperature and high-pressure steam will inevitably be generated.

Of course, Liu Xiu couldn't just discharge these high-temperature and high-pressure steam into the atmosphere on the surface of the wandering blue planet.

After all, if high-temperature and high-pressure steam is emitted on such a large scale, it won’t be long before the surface of the Wandering Blue Planet becomes a sauna steam room.

Of course, if all of it were used to generate electricity, it would not be possible to use it all.

Liu Qi also proposed a solution to this problem, which is to use the electricity generated by this to start the collider to produce antihydrogen atoms.

That's right, geothermal electricity is used to produce antimatter and store it. Then, this antimatter can be used to make bombs or used on unmanned spacecraft.

Of course, Liu Qi’s suggestion is to keep these antimatter until the mantle cools down completely. After the hybrid energy planetary engine is transformed, a large amount of antimatter will be needed to drive it.

After Liu Xiu finished reading Liu Qi's entire report on the cooling plan for the mantle and core, he looked at Liu Qi and said:
"I agree with your plan in principle, but I saw in the report that the demand for the geothermal heat exchange tube you invented is very high! So are you planning to treat these geothermal tubes as disposable items?"

After hearing Liu Xiu's question, Liu Qi nodded and said:

"That's right. The material used for these geothermal heat exchange tubes is ordinary steel, which is not a valuable thing, so it can be obtained in large quantities through interstellar mining. Moreover, if the geothermal heat exchange tubes made of steel are placed in the mantle, where the magma is transformed into rock due to the absorption of heat, they can act as steel bars in reinforced concrete, thereby increasing the tensile strength of the mantle."

After listening to Liu Qi's explanation patiently, Liu Xiu had to admit that Liu Qi's mind was quick and he could easily think of such a way to kill two birds with one stone.

Although this consumes a lot of resources, after entering the interstellar age, the things that are least lacking are actually not ordinary conventional resources.

What is lacking is technology and the means to utilize it.

Of course, while Liu Qi and Liu Xiu were discussing the feasibility of his mantle cooling plan, the wandering blue star that had already reached the star system where Origa VI was located was also operating according to the previous routine.

It first stopped at one thousand astronomical units away, and then sent out an unmanned exploration spacecraft to begin to conduct specific detection of the situation on the planet Origa VI.

Although Liu Xiu already had the data on the exploration of Origa VI from the Covenant, it would be better for him to conduct another exploration on his own for safety.

This time, not just one but multiple unmanned spacecraft were sent out to explore other planets in this star system.

Naturally, there is only one purpose, which is to obtain sufficient resources to implement the plan of mantle cooling for the wandering blue planet.

After all, according to Liu Qi's plan, the amount of steel required is really too much. Such amount of steel is enough to make another one million planetary engines.
