Chapter 156 Power
“…After realizing that relying on the mechanical structure and the current energy supply level, it was impossible to make the cone rotate at 600,000 revolutions per minute, especially it was impossible to make many - at least hundreds of thousands of such cones - reach such a rotation speed at the same time, I began to think about other possibilities.
My idea is very simple. Since the mechanical structure and material performance cannot be achieved, can we simply abandon the mechanical structure and material requirements?
We don't actually need it to rotate for too long, just one rotation is enough.
The question then becomes: how can we provide enough power instantly to keep tens of thousands or even hundreds of thousands of cones spinning at high speeds simultaneously? What kind of facilities or structures can provide enough energy?
I thought of the most powerful weapon created by our human world, the hydrogen bomb.
A hydrogen bomb explosion clearly has the instantaneous power required. The difficulty lies in how to utilize it.
I did some research and found the answer from some literature from the heyday.
During the heyday of the revolution, people had proposed the idea of whether it was possible to use hydrogen bomb explosions to obtain energy.
Simply put, find an underground cave that is large enough and has a strong enough geological structure, use the thick rock layers around the cave as a container, and then detonate the hydrogen bomb in the cave.
In this way, the heat, shock waves, etc. from the hydrogen bomb explosion can be discharged through the cave exit.
As long as the corresponding equipment is installed at the exit of the cave, the energy of the hydrogen bomb can be utilized.
We certainly know that if this plan is only for power generation, it is not actually feasible in engineering.
But now, we will modify it slightly to meet the current requirements.
We can also find a sufficiently strong and large underground cave, dig many passages leading to the surface, and place a special cone at the exit of each passage.
The energy from the hydrogen bomb explosion would be directed into these cones, propelling them into the sky at extremely high speeds.
Taking into account the special structure of the cone, after calculation, I found that during the process of friction with the air, they will spontaneously rotate violently.
Of course, after just a few turns, it will explode and disintegrate due to the enormous impact force and heat.
But it doesn't matter. During their previous few rotations, they had already released gravitational wave radiation that was quite strong in comparison.
We can also achieve slight differences in the frequency of gravitational waves by designing this cone in advance, thereby encoding information.
So, in this way, through the rotation of millions or even tens of millions of cones, we can radiate a complete gravitational wave signal to the entire universe.
Through calculations, I believe that a hydrogen bomb with an equivalent of 1 million tons of TNT can provide enough energy for the rotation of about 10,000 cones.
The total equivalent of nuclear bombs in our nuclear arsenal is about 30 billion tons.
Some hydrogen bombs are too powerful to be used, but removing them would still leave us with about 100 million tons of TNT, which would give us about 100 million cones, more than enough.
Through underground caves, the comprehensive utilization rate of hydrogen bomb energy can reach about 1%.
At the same time, the efficiency of the cone's rotation in converting energy into gravitational waves is about one in one hundred million.
Then, through this set of devices, about one billionth of the energy of this 10 billion tons of TNT equivalent hydrogen bomb will eventually be converted into gravitational waves, which is about 4.2*10^9 joules of energy.
If the entire broadcast duration is set at one hour, the average gravitational wave radiation power can reach about 1,100 kilowatts.
This number isn't huge. After all, the human body generates power ranging from a few hundred watts to a thousand watts, and this radiated power is roughly equivalent to the natural power of more than a thousand people gathered together.
However, for gravitational waves, I think this is already quite obvious. We cannot imagine that an alien civilization with super-technology would need to create ultra-high-power gravitational wave transmitters when using gravitational waves for communication.
For them, gravitational wave radiation of this power should be enough to be detected by them.
This is all I have in mind.”
There was silence in the conference room for a moment, and then thunderous applause broke out.
Sun Huiya, who had originally calmed down, suddenly turned red in the face and stood on the stage at a loss.
Liu Yu clapped his hands and looked at her, his expression full of emotion.
"The children have grown up..."
Although this is just an idea, the idea is enough. The rest of the engineering details will naturally be completed by others.
After detailed demonstration and calculation, the world government finally announced that the plan was feasible.
The World Government plans to mobilize all of civilization and spend about two years to complete the excavation and renovation of 2,000 gravitational wave transmitters - that is, the kind used to detonate hydrogen bombs, as well as the construction of corresponding ground facilities.
Each gravitational wave transmitter will launch between 20,000 and 40,000 special cones, bringing the total number of cones launched to 60 million.
Information about the human genome is encoded on these 60 million cones.
In the following period, not only more than 2 million "young people" under the age of 84, but also about 12 million elderly people who still have a certain degree of mobility, a total of nearly 15 million people, under the call of the world government, the new decision makers, all invested in this unprecedented large-scale project.
Everyone knew in their hearts that this was truly the last charge, the last attempt of the human world, and even the last effort.
If this attempt fails...
Then, the human world would no longer have the capital to make a second attempt. In fact, even the courage to try again would be lost.
In this case, this time, regardless of the future outcome, at least the thing itself must be done well.
Even if we have to try our best and risk our lives, even if ten thousand, one hundred thousand, one million, or ten million people die, we must complete this project!
Across the vast land, construction teams are rushing in all directions, convoys are speeding on the roads, and factories that have been silent for a long time are roaring again.
Soon, the assembly line for cone production was complete, and dozens of factories began producing them at a combined rate of about 80,000 per day.
The next thing to be completed is the underground cave exploration and site selection work.
Not only the naturally formed caves, but also the many abandoned underground bases have once again gained new missions and welcomed large numbers of construction teams.
Although there are only less than 100 million people left in the entire human civilization, at this moment, they have erupted with a construction enthusiasm that cannot be matched by the billions of people in the past.
