When summer comes, rain becomes the most common natural phenomenon in our daily lives. According to our understanding, if the rain is moderate, it can nourish all things and make the whole earth full of things. life. However, if the precipitation is too heavy, it will cause flooding, which will be a disaster for humans, animals and plants. However, in recent years, with the development and popularization of new energies, we have gained a new understanding of rainwater. Small raindrops can actually give us electricity. It is also the latest rain power generation technology developed by scientists. When this technology was first unveiled in 2017, it caused a worldwide sensation.
So, does it only produce electricity when it rains? In fact, it is notas the case. Just as we can use solar energy even on cloudy days or at night, the same principle applies to generating electricity from rainwater. Through experiments, scientific researchers have constructed a nanoscale film for rainwater that can be used to produce solar energy. produce electricity. When and join us in this layer Then put a layer of solar panels under the film, and we can use new energy to generate electricity even on sunny days.
So, what is the principle of producing electricity from precipitation? Is it because rainwater contains electrons? According to the experiments of scientific researchers, the reason why rainwater can generate electricity is entirely due to a nano-film layer that it comes into contact with after falling. This layer of film is composeded from two different layers of materials. Because rainwater has its own. own charge, the first film layer is responsible for absorbing positive electricity and the second film layer is responsible for releasing negative electricity. Once voltage is generated, current is generated.
However, at present, this technology is still in the experimental stage and has not been used like solar energy. The first is the installation of this nanofilm layer, which poses a big problem. According to calculations, if the world needs to use nano-films to generate electricity, the area of nano-nano films will need to cover at least the entire Shandong province, and precipitation will also need to be abundant. the earth to find such an ideal environment. The current production of electricity from precipitation is therefore still at the theoretical stage. After all, further research is nnecessary to move from theory to practice. In addition, there is the problem of the stability of precipitation electricity generation, because precipitation is not like sunlight, it is intermittent, which also makes it difficult for us to guarantee that it does not There will be no sudden power cut halfway. At the same time, the triboelectricity problem of nanofilms is not very stable at present. Scientists must first develop a relatively stable capacitor and then ensure the stability of electricity. The current calculation results indicate the stability and energy conversion rate of precipitation. Power generation can reach about 85%, but this is also a very ideal state, and it is still very difficult for us to reach it. Even according to scientists' hypotheses, if we can realize a "Dyson sphere" in the future, then we will be able to appropriateenergy from the sun. We need to know that the energy released by the sun in one second is enough for us to use. for 200,000 years, but it is In terms of current human technology, it is necessary toIt is more difficult than generating electricity from precipitation, and the road ahead is also very long.
By refining sodium in the sea, batteries are made to produce electricity for use. Seawater energy cannot be used directly to produce electricity.
The Nautilus is described in the novel as a slender, spindle-shaped submarine 70 meters long and 8 meters wide. It has excellent navigation performance and a maximum speed of 50 knots per hour.
It's an ideal submarine. The boat is powered entirely by electricity. Electricity is extracted from seawater and sodium is mixed with mercury to forWed a battery that replaces the Bunsen battery. is obtained after being converted into electricity and stored in batteries. ?
The food consists entirely of fish, seaweed, etc., so the crew's energy and daily necessities come from the sea. They require no land-based supplies and can sail on the sea indefinitely.
Detailed information
"Twenty Thousand Leagues Under the Sea" is one of Verne's masterpieces, which represents colorful imagination and the characteristics of Verne's meticulous and delicate work. in writing. The plot setting of the novel is bizarre and bizarre, vividly describing the mysterious underwater world; the language is lively and interesting, both the language of art and science, and the explanations of various underwater things are insightful and realistic. The Nautilus submarine particularly fascinates readers.
The submarine describedt in "Twenty Thousand Leagues Under the Sea" is called "Nautilus", and the Nautilus uses its thin hull of a few millimeters to withstand the challenges it faces after diving to a depth of 100 meters. . A shelled animal with enormous water pressure. This detail fully demonstrates Verne's extensive scientific knowledge.
