The People's Daily article "The future electricity comes from the sky" mentioned that the space power station is to move the solar power generation device on the ground into space, convert solar energy into electric energy in the air, and then send it to the ground through wireless energy transmission, so that the core sun of the solar system can provide inexhaustible clean energy for human beings through nuclear fusion.
The reason why the power station wants to "go to heaven" is because solar energy cannot be used efficiently on the ground. On the ground, solar energy is affected by the absorption and scattering of the atmosphere, the increase and decrease of clouds and rain, the change of seasons and day and night, and has many adverse effects. During the day, solar energy is very abundant. The solar power generation device works in geosynchronous orbit, and the overall power generation efficiency of the space power station is still considerable, even if the energy is lost in the process of multiple conversions to the ground.
However, in addition to the space power station can make full use of solar energy, the application of subversive technology enables human beings to make better use of solar energy than space power stations even if they are based on the ground. Of course, such "stunts on the ground" are not traditional photovoltaic and hydrogen power generation, and air conditioners without electricity also have such "gifts".
The clamp temperature invented by Mr. Zhu Ruodong in Xuchang City, Henan Province is synonymous with refrigeration in the patent name. "Self-source pinch temperature" is translated into daily life language, that is, "refrigeration does not consume electricity", abbreviated as "air conditioning does not consume electricity". The control method of residual heat clamping is similar to that of self-source clamping temperature control devices and vehicles (patent number: ZL 20 17 1027533.
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 a huge object like the earth. It uses the residual heat of the target itself as working energy to "convert" the heat of the heat source into electric energy to complete the clamping temperature. 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.
Temperature clamp is a mosaic with two functions of "self-source temperature clamp" and "waste heat power generation", and this feature is its technical core. "Self-source clamp temperature" realizes that clamp temperature does not consume electricity, not only consumes electricity, but also "waste heat power generation" converts waste heat into electric energy to obtain clean energy.
This embedded feature makes the clamp temperature device use extra waste heat to generate electricity 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 using waste heat to generate 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 energy 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 utilization and "sustainable cycle" of solar energy. 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 completely meets human needs, and it can be taken as needed without taking it, giving full play to the advantages of flexible resources.
Space power stations make full use of solar energy, but it is more sufficient than receiving solar energy on the ground with traditional clean energy technology, because they are all regional. The sky is fuller than the ground, mainly because it can get undiluted solar energy. However, the giant clamp heater is based on the solar energy obtained by the whole earth's heat storage, and it is global rather than regional in making full use of solar energy and clean energy. Compared with the "foot force" of the giant clamp heater, the power of space power stations is still a drop in the bucket, and only a few space power stations can achieve the purpose of clamping the earth to generate electricity, and moreover, they can not play an obvious role in cooling the earth. The giant clamp heater clamps the earth to generate electricity and also cools the earth. On the contrary, the embedding of giant pincers to warm the earth requires the attenuation of solar energy reaching the earth, because even if it is attenuated, solar energy can provide enough clean electricity to fully meet human needs. Undiluted solar energy exceeds the demand of human beings, and the "relative surplus" part that cannot be converted into thermoelectric energy is blocked in the local gas system, which intensifies the greenhouse effect;
The construction of space solar power station is facing great technical challenges, both in weight and scale, far exceeding the existing space facilities. The area of a single space power station is at least equivalent to 1400 football field. The key areas such as materials, transportation, spacecraft control, on-orbit assembly and maintenance, and wireless energy transmission technology are in urgent need of technical breakthroughs, which require huge financial and material resources and cannot be realized in a short time, and have little practical significance for the imminent carbon neutrality cause.
The temperature clamping device is a mature technical scheme. The giant clamp temperature device will clamp the waste heat of the earth to generate electricity, thus activating the "heat accumulator" link of the earth. This kind of solar power generation will show four characteristics: 1, and large heat storage: in the range of the earth temperature 1-2 degrees, the stored heat will be very considerable and can be used by human beings. Moreover, the demand for electricity is randomly distributed in time and space, and the heat generated by thermoelectric conversion will not make the earth temperature fluctuate; 2. Globality: equivalent to being placed in the hands of everyone in the world, everywhere; 3. Flexibility: As individuals, we can take out the waste heat of the earth anytime and anywhere to realize thermoelectric conversion, and we can take it as needed without taking it, giving full play to the advantages of flexible resources; 4. Economy: For human beings, the earth is a free natural heat accumulator without any investment. Its problem is to speed up the popularization and application, replace traditional air conditioners with daily life, use giant clamp heaters in society, and use the solar waste heat obtained by the earth to generate electricity. In the ideal situation of popularization and application, the clamp temperature device technology can directly help the current carbon neutralization process.
Occam's razor's "simple and effective principle" tells us, "Don't waste more things to do, you can do good with less things." Space power station and temperature clamp are both technical explorations that make full use of solar energy to generate electricity. If we can choose the best shaver, "electricity falls from the sky" will become a reality that benefits mankind as soon as possible.
