The forum finally ended with six days of speeches.
Qin Fei benefited a lot from various speeches from dozens of scientific fields.
Such a superficial speech could not help Qin Fei learn anything specific for the time being, but But it greatly expanded Qin Fei's horizons and height.
After two days of discussions and exchanges, we came to the main topic of this forum, which is the issue of global warming.
According to the current situation, global warming is an unsolvable problem, because the energy the earth receives from the sun is constant, and even if it changes, it will not be too extreme; but now the earth uses a large amount of nuclear energy.
It means that humans are creating heat out of thin air Over time, even if a large amount of farmland is converted into forests, the world has almost reached more than 80% green space coverage, and even deserts are planted with drought-resistant plants, the problem of global warming still cannot be completely solved.
Global warming has now become the curse of earth civilization.
A long time ago, everyone said that since there is a lot of energy, how to store it?
Scientists used their imagination and found a way to plant trees.
In the words of scientists, all life on the earth is cured. of solar energy Plants are also solidified energy.
Planting trees and restoring the original jungles on the earth can not only absorb carbon dioxide, release oxygen, purify the air and other benefits, but also store heat energy; store heat in plants.
And when grown, a large number of plants themselves are good resources.
This is a virtuous cycle The results are very good.
Over the past three hundred years, this method has solved the problem of global warming very well, and the global environment has finally stabilized.
But then there is a problem.
The energy that human beings need is always endless, and nuclear energy is constantly expanding, so that energy consumption increases sharply, and there are more and more nuclear power plants; this is a vicious circle.
Every nuclear power plant is an artificial little sun.
It is continuously releasing heat; whether it is nuclear fusion or nuclear fission, it is adding heat "out of thin air" to the earth's environment.
Today, the increase in heat is finally approaching the red line of equilibrium again, and the issue of global warming is once again facing the earth's civilization.
The earth is the foundation of humanity.
No one allows any loss.
But cooling a planet is easier said than done This is not a person who can just blow on the fan, blow on the air conditioner, go swimming, and eat ice cream when it's hot.
Today's situation is like installing an air conditioner in a closed space, cooling one space and heating another; but the energy of the entire space has not disappeared.
The energy generated by the air conditioning is diffused into this enclosed space.
The final result is that the overall temperature of the enclosed space slowly rises The earth as a whole is this closed space "Pumping the earth's water into space to cool it, and then putting it back into the sea to cool down.
It is equivalent to giving the earth ice cream," said a scientist.
The result didn't even take a minute before this fantastic idea was denied; scientists spoke with data, and the energy spent to lift water into space was enough to boil water thousands of times.
All this energy will remain in the atmosphere.
So, the idea clicked.
"What about directly cooling the air?
The air above the earth is directly extracted from space, and then re-injected into the earth after cooling."
Another new scientist has proposed an idea.
It looks good.
At least Qin Fei thinks it is feasible.
There is no need to raise the sea water and directly extract air from outer space for cooling.
But it was still rejected.
The idea seemed feasible, but the atmosphere at high altitudes on the Earth was unimaginably thin.
Doing so would be a huge and unimaginable project in itself; and if you want to float the device at this altitude, you need to overcome the friction of the thin atmosphere to fly around the earth, which requires constant acceleration.
This energy will eventually fall into the atmosphere.
Finally, through calculation, it is basically impossible to adjust the climate directly through cooling.
Even if a certain method can succeed, the huge project will directly bring down the industrial system of earth civilization.
Later, someone proposed spraying suspended crystal particles in the atmosphere to reflect sunlight; however, as soon as this idea came out, climatologists scolded it as a bloody sprinkler.
You still think the air is not polluted enough.
Immediately, someone said that we should spray glass sheets between the earth and the sun to intercept some of the sunlight; soon astronomers and space weather experts yelled that you still think space is not chaotic enough. in space.
Fragments as small as a fingernail may cause serious trauma to the aircraft.

If there are countless fragments, they are enough to wear down any man-made object in space.
It is conceivable that if some thin sheets are placed between the earth and the sun, stability can be maintained even for a short period of time.
But over time, it will inevitably be thrown everywhere by the complex gravity of space.
The solar system is not just the earth and the sun, and the relative stationary point of the Lagrangian point is just a theoretical point.
Eight planets orbit the sun.
In fact, the gravitational field of the solar system is changing all the time.
How about arranging a large number of reflectors from the ground to reflect the sunlight from the equatorial part into space?
After urgent calculations, everyone had to regretfully announce that the idea was good, but it could only be said to be better than nothing, and would cause unimaginable damage to the earth's ecology.
Later, some scientists thought about whether they could develop a large number of Seer engines, which are devices that can convert thermal energy into magnetic energy and then into electrical energy.
This is a "thermal engine" that is very suitable for use on the current earth.
The Seer engine in a laboratory environment can reduce the ambient temperature to below zero.
Therefore, if we produce it in large quantities, we can extract all the heat in the atmosphere and inject it into the power grid to save energy for the development of the earth.
This is a good idea and is based on a feasible foundation.
Moreover, the Seer engine can be manufactured on the moon and then airdropped to the earth for use.
The world's top scientists discussed for a long time and finally finalized the first feasible method.
But this method is not so perfect.
It will inevitably use countless Searle engines, because the efficiency of Searle engines is not as high as imagined, and its manufacturing cost is high and maintenance is troublesome; therefore, this can only be used as a backup plan. .
"Is there anything better?
It needs to be feasible, and preferably simple and feasible.
The Seer engine can only be a backup plan.
Now the earth has begun to have a fever, and we can't wait too long."
The scientists quarreled with each other, speaking in several languages Hengxing, even with a translator, made Qin Fei dizzy.
"It's so noisy."
Zhang Jianfeng looked unhappy.
This guy finally realized that he was ignored in the forum this time.
"It's so noisy."
Qin Fei looked at the quarreling scientists.
He didn't expect that these top scientists would also roll up their sleeves one day, and they were all quarreling.
No, Qin Fei saw Dean Long Wenjie push a Korean scientist who had a disagreement to the ground.
"These scientists are definitely taking the opportunity to fight with each other.
I can guarantee it with tonight's dinner."
Zhang Jianfeng was gnashing his teeth at this moment.
But he was still reasonable, knowing that he was still somewhat different from a freak like Qin Fei; there were more than 300 elite students from all over the world, but only a few were actually named, only a dozen or so.
However, at this moment, when Qin Fei saw the lightning and thunder promotional video about global warming, his head suddenly cramped, and he suddenly thought of a way.
It suddenly seemed like explosives had encountered an open flame.
In an instant, Qin Fei's ideas were perfected and he even roughly calculated some of the data.
It's 100% feasible.
Qin Fei's eyes widened immediately.
Gu Qingyan had already left.
Such a venue was obviously not suitable for a gentle woman; Qin Fei had no choice but to go directly to the dean, Long Wenjie.
"What's going on?"
Long Wenjie was rolling up his sleeves and fighting.
Well, that's reasonable.
He was very dissatisfied with being disturbed by Qin Fei.
"Principal, I have thought of a method.
Free novels bring you joy and joy ---> storyskyline.net
The feasibility should be above 99%."
Well, Qin Fei was a little more modest, really a little bit. s: I accidentally wrote more than two thousand words, and there will be an update later:
