The “mixed energy reactor†of the Chinese Academy of Sciences will enable a century of uranium resources to be used for thousands of years.
On September 23, the day before the official closing of the 4th China Science and Technology Fair, in the exhibition area of ​​the China Academy of Engineering Physics of the Military-People's Integration Museum, a model with red and blue currents passed through, surrounded by many inquiries.
This model is a fission hybrid energy reactor known as the “millennial energyâ€.
In contemporary society, the traditional energy crisis has become an urgent issue. Traditional energy sources such as coal and oil are depleting, and the large amount of greenhouse gases emitted by combustion also causes extreme changes in the climate. People have been studying to find new energy sources.
Uranium resources, photovoltaic solar energy , nano-power generation... At this fair, new energy is not allowed to become the focus of attention. Many scientists pointed out that solar energy, wind energy, bio-energy, hydrogen energy, combustible ice, nuclear fusion energy and tidal energy may be the best choices, and can become the "Noah's Ark" of human energy.
These new energy sources unveiled at this year's Expo will probably be used on a large scale to solve the energy crisis and achieve sustainable development of human society. Traditional energy crisis This century, oil will be exhausted. Imagine the world without energy: mobile phones, computers, televisions all black screens, cars, planes completely strike, not even fire. When the sun sets and the night falls, the world will fall into the boundless darkness.
How many years can the world's traditional energy be used?
As far as oil is concerned, according to relevant reports, it is estimated that the world's total oil reserves are between 270 billion tons and 650 billion tons. At the current rate of consumption, for another 50-60 years, the world's oil resources will be exhausted. If the new energy system is not yet established, the energy crisis will definitely sweep the globe.
For this point of view, Lu Shirong, a researcher at the Chongqing Research Institute of the Chinese Academy of Sciences, believes that there is an exaggerated component. What is worthy of recognition is that it also reflects people's concerns about the use of non-renewable energy. At the same time, the harm caused by the use of fossil fuels to the environment is already obvious to all. The air quality is deteriorating, the global climate is warming, and human beings face severe survival challenges.
How to make rational use of traditional energy sources, develop new energy sources, and finally achieve sustainable development has become a hot topic of global attention. The "hybrid energy reactor" allows for hundreds of years of uranium resources to be used for thousands of years. No one wants to wait for the depletion of fossil energy. The future of new energy is the direction pursued by human society.
The new energy lineup that appeared at this year's Expo will be called "luxury." Nano-generators, mechanical energy is converted into electrical energy, and it takes 4,800 steps to fully charge a mobile phone. Solar photovoltaic panels make life in a mobile villa more convenient...
There is also a “mixed energy reactor†that has received much attention. On September 23, the reporter saw the conceptual model called “Z-pinch-driven fusion-fission hybrid energy reactor†in the exhibition area of ​​China Engineering Physics Research Institute of Science and Technology Expo. It is called the millennium with the most potential in the future. energy".
Fission divides the atom into two, and fusion makes the atom two-in-one. Both processes can release huge energy. But these two methods have drawbacks. Fission generates a lot of radioactive waste, and fusion requires a lot of energy to carry out and achieve controllable.
The fusion fission hybrid reactor can not only reduce the external energy input, but also complete the complete combustion of nuclear fuel and avoid the generation of radioactive waste. The global uranium resources add up to about 100 years, and the hybrid reactor can extend its service life to more than 1,000 years.
"From 2035 to 2040, we will strive to build an experimental reactor. The construction of the experimental reactor means that we are not far from the 'millennial energy'." Field staff at the exhibition area, Senior Nuclear Energy Center, Institute of Nuclear Physics and Chemistry, Chinese Academy of Sciences Engineer Liu Zhiyong said. "Super Lithium Battery" allows new energy vehicles to open "infinity"
Mr. Zhang, who lives in Chengdu, has a Tesla family. He likes to travel by car. He has no plans to drive far away in the past two years. This Tesla is theoretically full of electric energy for 500 kilometers, but after running fully, it actually runs about 390 kilometers, almost running from Chengdu to Chongqing. Mr. Zhang drove out and often had to calculate for a long time.
All new energy sources have their own limitations. For example, wind energy is converted into electrical energy, which is limited by the region. Solar energy is affected by weather factors, while the energy of new energy vehicles is affected by battery energy storage.
Nuclear reactors are the only large-scale power generation method without carbon emissions. However, according to current technology, many people are worried about the nuclear waste that it produces with radioactive hazards. "The conversion efficiency of nuclear energy is very high, but the danger is also high." Lu Shirong said that some nuclear power plants in Japan are being shut down.
However, the combination of new energy and new technologies can create endless possibilities in energy. The "super lithium battery" that appeared at the Expo will enable new energy vehicles to last more than 500 kilometers. The lithium-sulfur battery itself does not generate electricity, it is an energy storage battery. A solar cell is a battery that produces energy and produces energy as long as it has light.
"If new energy vehicles are equipped with energy storage batteries and solar cells in the future, then under ideal conditions, the mileage of this car can be opened to 'infinity'." Lu Shirong said.
Who is the future energy source?
Requires low cleaning costs and high conversion efficiency
After 100 years or even 200 years, which new energy can best meet our daily needs?
New energy technologies are constantly being updated and are constantly competing. "Only new energy technologies with low production costs and high conversion efficiency can survive the survival of the fittest." Among many new energy sources, Lu Shirong prefers solar cells.
Lu Shirong's team is working on a "printable thin film solar cell." At present, the more common solar cells are rigid silicon-based batteries, which are costly, cumbersome, and complicated in preparation process. Lu Shirong intends to reduce the production cost of solar cells and increase the conversion power. The solar cells he studied were very thin and could be bent. The most important thing is that the battery can be produced like a newspaper.
Lu Shirong also revealed the most cutting-edge technology in the world of new energy research. He said that experts are currently working on a "semi-permeable membrane" through which electricity can be generated. To put it simply, if a container has a layer of salt water and a layer of water, a semi-permeable membrane is placed in the middle, and some ions can penetrate the membrane, and some ions cannot. This process produces electricity. If the film is placed in the middle of sea water and river water in the future, it can automatically generate electricity. The key to this technology is the “semi-permeable membraneâ€, which is currently under development.
Huaxi Dushi Bao reporters found that there are many disputes about the energy that humans will be able to use in the next 100 years, including nuclear energy, hydrogen fuel, combustible ice, food energy, garbage energy, algae energy and so on. However, no matter what, clean green, low cost and high conversion efficiency are definitely the criteria.
