What will the world be like if controlled fusion becomes a reality?

In today's technologically advanced world, controlled fusion has long been nothing new, but there are still many people who wonder why humans are developing controlled fusion, and it starts with energy.

So far, most of the energy needed to meet human life and production comes from the sun, such as oil, natural gas, coal and wind power, etc. Even the food we eat is also an alternative way of solar energy.

The sun gives us energy, but where does it come from? The answer is: the uninterrupted hydrogen-helium fusion reaction inside.

With the current level of technology, mankind has been able to use nuclear fission perfectly to generate electricity, but don't look at the difference between "nuclear fission" and "nuclear fusion", they are actually two fundamentally different things, not only in the amount of energy generated, but also in the amount of energy generated. This difference is not only in the amount of energy generated, but also in the demand for "fuel".

According to relevant statistics, the fissile material is only enough for human use for nearly a hundred years, while the fusion material is nearly endless, such as the Earth's oceans have about 40 trillion tons of deuterium, if it is fully utilized, 1 kilogram of deuterium can produce almost 100 million degrees of electricity, which is how amazing the number.

What's more, this is only the raw material in the earth's oceans, if you count the raw material on land and extraterrestrial celestial bodies, it will be an even more amazing number.

If humans can fully control nuclear fusion, not only can significantly reduce the dependence on the sun, and even rely on the huge energy out of the solar system is not an unattainable dream.

In addition, nuclear fusion is also a clean and efficient energy source, and if it becomes fully popular, it is bound to significantly improve and repair the Earth's ecosystem, which is the direction of development that mankind has been pursuing after realizing that industrial development can do great damage to the environment.

However, the development of controlled fusion with such a promising future is not smooth, due to the slow progress in some fields, resulting in "only 50 years left" before mankind can really master and popularize controlled fusion.

However, even if controlled fusion is still not really widespread, it does not affect our expectations of it, and this brings us to a very important question: if controlled fusion is fully commercialized in the future, then what will the world become? Let's talk about it separately.

Agricultural changes

Agriculture is the basis of everything, as the saying goes: "Man is iron and rice is steel, one meal is hungry", only when you have enough to eat can you really talk about development.

If controlled fusion is fully popularized, then the era of one acre of fixed food production will become history, those originally unsuitable for food production by the sea will appear a building of soil-less cultivation, synthetic fertilizer key energy problem is completely solved, the yield of an acre of land will depend directly on the height of the building, as well as the difficulty of obtaining purified water.

The significant increase in the production of food crops can directly contribute to the increase in livestock production, food will become cheap and easy to obtain, the food crisis will become a complete thing of the past.

Industrial changes

Because of the abundance and low cost of energy, the cost of many industrial activities, such as smelting metals, decomposing minerals, and transportation, will become extremely low, and the cost of these activities may be reduced to the cost of labor and time.

Due to the ultra-low prices of industrial raw materials, will in turn to stimulate the price of finished industrial products, there will be more large machinery to mine minerals or some other industrial activities, so the cycle continues, may be an ordinary people are able to complete the previously expensive industrial production at a very low cost, industrial development will be more vigorous and dynamic.

What is certain is that when the energy is nearly unlimited, the internal combustion engine car will become a thing of the past, the electric powered car will become completely mainstream, because the remote charging equipment laid on the roads at all levels will be able to charge the tram running on the road without interruption, the tram has been criticized for the range problem will be completely solved.

The decline in the cost of various raw materials will greatly promote the popularity of multi-layered roads, unmanned logistics and ordinary people's carriers will be separated, and the vacuum capsule technology, which is now in the experimental stage, will also be popularized because of the emergence of unlimited energy.

What's more, because of the convenience and cheapness of land transportation, sea and air transportation may shrink and finally become a supplement to land transportation.

Climate change

Nowadays, many people put air purifiers in their homes due to severe industrial pollution, and when nuclear fusion becomes fully popular, the low cost will make some large outdoor air purification devices a reality. Hospitals, schools, factories and other special areas will be equipped with such purification devices nearby.

Once this device is completely popular, then the whole world will become a huge climate regulator, under the help of this regulator, the heat island effect and a series of greenhouse gases caused by the impact will be gradually adjusted to a normal state.

It goes without saying that urbanization is increasing at an extremely rapid pace. Compared to the past, the city will become more three-dimensional, simply "up" can no longer meet the needs of human use, "down" development will certainly begin to appear.

This is mainly because of the food sufficient to liberate a large number of productivity, and the new population will certainly have a more urgent need for living space.

In addition, the booming industrial development with "downward" urban complexes, everything that was only in science fiction movies will come to life, such as the holographic sky simulation that appeared in the "Wandering Earth".

Social change

Because the productivity of almost all liberated, so the survival of the individual recently this is no longer a problem, human beings for millions of years has been running for food era finally came to an end.

In this way, people have more time to learn, to enjoy life, the level of science and technology will become more advanced and developed because of the joint promotion of a large number of scholars who are no longer running for a living. The interconnection of all things is also no longer something that remains only in theory, and primary intelligent mechanical beings will develop together with humans.

Finally, because of the nearly unlimited energy, the asteroids in the Kuiper Belt will begin to have mining value and significance, and humans will touch the "threshold" of full exploration of the inner solar system for the first time.

Just as people imagined centuries ago that we should have built prosperous cities on Mars by now, all human imagination is actually based on the current level of technology, which means that imagination and reality may have a great error.

So when the future of mankind into the era of full-scale nuclear fusion, there may be changes as predicted above, or even more exaggerated, but there may also be far from that fantasy.

But all in all, as long as the future world is not completely destroyed by war, our earth will become more and more livable, and human civilization will become more and more developed.
