Of course, resources are limited, and nuclear power cannot solve all resource problems.

It is now believed that primitive man first used natural radioactive sources. For example, a primitive man accidentally ate the corpse of an animal that had been killed by radiation, smashed it in his mouth, and did not find any difference with ordinary raw meat.

Human resources will eventually be in short supply, and it has nothing to do with what to use first.

Human genes can be weird, and their physiognomy can be very ......If human beings assume that the first to master nuclear energy proves that the world at that time must have been full of nuclear radiation;
-
This is a trend in which the production of nuclear energy has been accompanied by the peak of chemical energy, and there are limitations.
-
Nuclear energy is one of the most promising sources of energy for the future. There are two ways to develop nuclear energy: one is the fission of heavy elements, such as uranium; The second is the fusion of light elements, such as deuterium, tritium, lithium, etc.
-
That proves that the world must have been filled with nuclear radiation at that time, and can human beings exist now?
-
Although it occupies a small size, it has to be handled carefully because of the radiation it contains, and it has to face considerable political problems.

Current fusion technologies, including tokamaks, have made rapid progress in order to achieve beneficial energy output, requiring fusion to produce much more energy than is needed to create the conditions for fusion, and there is still a long way to go before commercial application. Fusion-fission hybrid reactors only require that the energy produced by fusion is almost equal to the energy consumed. Therefore, it requires less fusion than pure fusion reactors, which is a shortcut to the commercial application of fusion energy.
The so-called fusion-fission hybrid reactor uses neutrons produced by fusion reactions to produce nuclear fuels such as plutonium-239 or uranium-233 in the uranium-238 and thorium-232 cladding outside the fusion reaction chamber, while releasing fission energy. From the point of view of energy gain and loss, fusion-fission hybrid reactors multiply fusion energy by fission, the value of which can reach an order of magnitude. Therefore, as long as the fusion nucleus is close to or equal to the gain and loss of energy, it has a building meaning.
In fusion reactors, it is necessary to maintain the subcritical state of fission, but not subcritical. At present, some large tokamak units have met the requirements of hybrid reactor fusion cores, and fission is a mature technology that can be directly adopted. Hybrid reactors reduce material requirements and are a commercial transition reactor type of pure fusion reactor.
The so-called nuclear fusion power station is to use the energy released by the fusion device to generate electricity, and the design principle of the fusion device is basically the same as that of the hydrogen bomb.
Since the energy released by the nuclear ** is instantaneous and enormous, it is very difficult to safely convert the energy produced by the nuclear ** into usable heat and electrical energy. In the envisaged nuclear power plant, the nuclear installation is in a huge cave**. Before, liquid metal sodium is sprayed into the hole, and the sodium forms a certain distribution around the device, thereby absorbing a large amount of energy.
At the same time, it can effectively reduce the strength of the impact on the blasting hole wall. After that, the heated sodium is extracted from the hole and forms a heat exchange with the second circuit of the power station, thus generating electricity.

No, because although controlled nuclear fusion can be achieved, it is still a future technology worth exploring, and there is no guarantee that human resources will be inexhaustible, and inexhaustible requires the joint efforts of human beings.

I have time to read my article "Controlled Nuclear Fusion"Artificial sun"Why won't it work? 》.Who is faster at the speed of light or the speed of sound? 》…Look"A jasper orchid chasing stars in Lingjing Lake"Can.

No, the energy produced by nuclear reactions is also a finite energy source, which does not mean that humans can have an inexhaustible source of energy.

The current development speed of human society has been surpassing the unprecedented progress of development, and it is precisely in this way that our current human beings can create such a colorful society in which human beings live. So this is a big question about whether our future humanity should go in which direction or in a roundabout way? We have now reached a certain point in the development of the earth, which is a fact determined by our current development, so one day the entire resources of the earth will be used by our human beings, and now we are also taking a kind of artificial energy is:
Nuclear energy. So why can't nuclear energy be used and developed on a large scale? The reason is actually very simple, mainly the following points.
First, the development of the whole world is uneven at present. First of all, the first point is that the development of our current world is very unbalanced, and it is a factor determined by its own limitations, because the current situation of extremely unbalanced development in the whole world, the developed countries are many years ahead of the developing countries, and the economic, political, cultural, educational, scientific research, etc., all need time to slowly balance the development, such a gap, many countries in the third world do not have the strength to develop the development of nuclear energy. <>
Second, the development of nuclear energy requires a lot of technology. Secondly, the second point is also super realistic, that is, there are few countries in the whole world that have nuclear energy, and the reason is very simple, that is, there is no money, no technology, and at the same time, the technology is blocked by advanced developed countries. <>
Third, nuclear energy is too harmful. Finally, it is very difficult to use the resources of nuclear energy as a whole. For example, in Japan, the tsunami caused by the 2011 Japan Great ** directly forced the entire Fukushima nuclear power plant to stop operating, and at the same time, the nuclear leakage also made the surrounding countries of the entire Pacific Rim very afraid.
Therefore, the environmental protection measures for the entire use of nuclear energy must keep up with the development of nuclear power plants.
-
It's not that it can't be developed, but if nuclear energy is used on a large scale, it is likely to lead to World War III. So in order to avoid this kind of thing, there is no large-scale exploitation of nuclear energy.
-
Although nuclear energy is a way of generating the largest amount of energy known to mankind, it will also produce a large amount of nuclear waste when it is produced, which will greatly affect the surrounding environment.
-
Because the utilization of nuclear energy is very difficult and easy to cause environmental pollution, it is impossible to use and develop nuclear energy on a large scale.

For humans, the unknown is what they are afraid of, and the reason for being scared is because ghosts are completely alien and unknown creatures to humans, and if scientists confirm their existence, humans will not be afraid.
If the earth rains for 10,000 years, the water level of our sea level will continue to rise, and the land where we live will be flooded, and at that time, human beings will become extinct because their homes are flooded and the food they grow cannot be exposed to the sun.
