It is reported that Hefei Institute of Material Science, Chinese Academy of Sciences has a fully superconducting tokamak nuclear fusion experimental device called "Artificial Sun", which will challenge the new scientific research goal of core electron temperature 1 100 million degrees Celsius and 100 second long pulse plasma before the end of April.
Humans have already mastered controlled nuclear fusion technologies such as hydrogen bombs, but the huge nuclear energy generated by them is beyond human control and will destroy the earth. The "artificial sun" is controlled nuclear fusion, which can be controlled by human beings. Only by using almost inexhaustible raw materials on the earth can we continuously generate safe nuclear energy, and then use thermal energy to generate electricity, and then convert it into electric energy to meet human demand for clean energy, replacing traditional fossil energy. The inexhaustible nuclear energy will become a kind of "ultimate energy" that human beings dream of. On this "ultimate energy" road, how to produce nuclear energy safely and controllably is a difficult problem and key. The success of "Artificial Sun" at 1 100 million degrees Celsius for 100 second this time pushed controlled nuclear fusion's technology to a new height.
In fact, apart from the arduous exploration of "artificial sun", there is another potential "ultimate energy" path, that is, how to develop and utilize solar nuclear energy that can reach the earth safely and continuously: human beings have many technologies to convert solar energy received by the earth into electric energy and serve mankind. Among them, human beings have high hopes for hydrogen energy and photovoltaic power generation, but there are still their own problems. Only a small part of this solar energy can be converted into electric energy, and most of it will reach the surface, become waste heat and radiate back to the atmosphere. Moreover, due to the greenhouse effect, these waste heat can not be well radiated to the outside of the atmosphere, and is blocked in the ground gas system, which intensifies the climate warming. On the one hand, endless solar energy is wasted and cannot be used as "ultimate energy"; On the other hand, compared with human needs, there is still a huge gap between photovoltaic power generation and hydrogen energy conversion, and human beings have to explore "artificial sun" as the "ultimate energy".
How to control, fully and freely convert the solar energy obtained by the earth is a difficult problem, and it is also the key to this "ultimate energy" path, which needs subversive technology to overcome-the patented technology of temperature clamp invented by Mr. Zhu Ruodong of Xuchang City, Henan Province can cross the natural barrier and become a thoroughfare.
The pincer temperature in the patent name of pincer temperature device is synonymous with refrigeration, and "self-source pincer temperature" is translated into daily life language, which is "no electricity refrigeration" and abbreviated as "no electricity air conditioner". The control method of waste heat clamping and self-source clamping temperature device, vehicle (patent number: ZL20 17 10275353.6) and utility model patent self-source waste heat. The clamp temperature device completely breaks through the technical framework of "inverse Carnot cycle, refrigerating the air in the closed space through" heat exchange "in traditional air conditioners, and constructs the path of target waste heat from high temperature end to low temperature end. The clamp temperature device can directly clamp the heat source of a solid target, which can theoretically be the earth. It takes the afterheat of the target itself as working energy, and "converts" the heat of the heat source into electric energy to complete the temperature clamping. Direct clamping temperature of solid target heat source is its application characteristic superior to traditional air conditioner, which can only refrigerate ambient air. The temperature path of the fixture is divided into three parts: a, the heat pipe in the main part is a channel for the self-transfer of waste heat; B, the clamped target heat source is communicated with the hot end of the heat pipe as a high-temperature heat source, and although waste heat is continuously accumulated, more self heat can be transferred through the heat pipe to cool down; C, a heat accumulator composed of solid-solid and solid-liquid phase change materials, one end face of which is communicated with the cold end of a heat pipe to receive waste heat from a target object, and the other end face of which is communicated with a thermoelectric generator to thermoelectric convert temporarily stored waste heat into useful electric energy, and the heat accumulator always keeps a latent heat state dynamically, so that its stable phase change temperature forms a temperature platform during the latent heat period, and the cold end of the heat pipe is communicated with it to become its stable cold end temperature.
Although the temperature difference is needed when choosing the thermoelectric generator as the heat energy conversion element of the pinch device, this temperature difference is not other temperature differences, and the temperature difference of the thermoelectric generator element is only the working temperature difference, not the environmental temperature difference of the traditional air conditioner. The working temperature difference of thermoelectric power generation is far from the target heat source, and its temperature difference area is small and the difference is small. This temperature difference can also be maintained by converting electric energy, which can be obtained simply, easily and economically. Even so, there is a better technology to optimize thermoelectric generation, so that the application of clamp temperature device is no longer limited by temperature difference.
The clamp temperature device is a chimera, which has two functions of "self-source clamp temperature" and "waste heat power generation", and this feature is its unique trick to ask the earth for nuclear energy. "Self-source clamp temperature" realizes that clamp temperature does not consume electricity, not only does it consume electricity, but "waste heat power generation" converts waste heat into electric energy and obtains clean energy.
Through this embedded function, the clamp heater can also get extra power when it is used for clamp temperature. Obviously, by clamping the temperature of solid objects such as walls and indirectly clamping the air in the greenhouse, the ambient temperature in the greenhouse can be clamped and the refrigeration function of traditional air conditioners can be exerted. However, the refrigeration of traditional air conditioners not only consumes high power, but also emits waste heat to the atmosphere. The temperature clamp does not use electric air conditioner as air conditioner, which is superior to traditional air conditioner and has the trend of social application. Once used in society, countless pincer-like temperature devices will be equivalent to a huge pincer-like temperature device, which can clamp the temperature of the earth.
This embedded feature also enables the temperature clamping device to additionally clamp the temperature of the target object when generating electricity. A single clip-on heater can't reflect the power of the earth's waste heat to generate electricity, but the macro clip-on heater also has embedded characteristics, radiating solar radiation into the earth's waste heat like a bag, and then taking it out at will to convert it into electric energy, showing the efficient use of solar energy and "sustainable cycle". The process of "waste heat power generation" of the earth (a considerable part of which comes from solar radiation) is also the process of "self-heating" of the earth. When solar energy is needed from the earth, it also cools the earth-"waste heat power generation", and the waste heat of solar energy is converted into electric energy, which is no longer discharged into the atmosphere, reducing the heat accumulation of the earth-atmosphere system; Synchronous, the earth's "self-source clamp temperature" does not consume electricity, so it does not emit carbon dioxide, which means that the quilt covered by the earth becomes thinner, reducing the interception of the residual heat radiated back to the outside of the atmosphere by the earth. These two synchronous processes both reduce the heat accumulation in the earth-atmosphere system, and both reduce the greenhouse effect and climate warming. In other words, the giant clamp temperature device is a clean technology that uses the residual heat of the earth's solar energy to generate electricity synchronously, which conforms to the direction of carbon neutrality. The tongs heater also activates the earth, a natural heat accumulator, so that human beings can take out the solar waste heat from the earth at any time and anywhere. The thermoelectric conversion fully satisfies human beings, and takes it as needed without taking it, giving full play to the advantages of flexible resources.
