Recently, the news about "China quietly ordered the closure of bitcoin mines" spread like wildfire. Some media learned through insiders that the central bank held a closed door meeting to rectify some mines with non-standard electricity consumption

in fact, the rectification and treatment of Mines started last year, especially after the closing of domestic exchanges last year, the relevant regulatory authorities also discussed the issue of mine retention, but the conclusion is that the reasons for closing mines are not sufficient, and the mines have not caused more social problems, and the risk points are not clear, so no specific arrangements have been made. However, all localities have received "window guidance", that is, local enterprises can not participate in digital currency mining

in 2016, China's power generation ranked first in the world, and the total power generation accounted for 25% of the world. In this case, according to common sense, mining power in China is indeed the most abundant, especially with the decline of China's economic growth, the wasted power resources are increasing

the electricity of power stations can not be stored, but if the electricity is converted into digital currency, it can be stored. In fact, if China's surplus power generation can be converted into bitcoin for storage, it should be the most efficient mode of proction and operation. It is equivalent to procing US dollars with electricity. It is a processing export mode with the highest added value

in addition, according to the historical development, most of the power in the future may be consumed by computers. This is a judgment I made, which can be witnessed by our generation. In our daily life, the proportion of electricity consumption will be lower and lower. In the future, mankind will solve all kinds of problems by means of digitization and blockchain, and "mines" will only increase, not decrease. Especially with the development of artificial intelligence, space exploration and other fields, the demand for computing power will increase exponentially

electricity is just a kind of energy, just like a person, the biggest energy consumption is not the limbs, but the brain. The human brain is a 24-hour machine. A thinking person's brain consumes 75% of the liver's stored blood sugar every day, and the oxygen consumption accounts for 20% of the whole body's oxygen consumption. The more the brain thinks, the more glucose the neurons need

When the electric lamp was invented 200 years ago, people thought that the best use of electricity was to light the bulb. Has the final say that what electricity market will be most effective in future? p> No one can see electricity. Up to now, it is difficult for many people to understand the mystery of its existence, but electricity has changed the world. The influence of many virtual things is often greater than that of physical things. What does "digital assets" mean to China and the world? I think it is difficult for many people, including the government, to make clear at this time. What we need to reflect on is that apart from the four great inventions, such as electricity, light, telephone, computer, digital currency and so on, how many of the things that are pushing mankind forward are invented by China

when a phenomenon appears, we must study the background and logic behind it. The future competition can be said to be military competition, economic development competition and financial competition, but it can also be said to be ideological and computational competition. It's easier to close mines than to stop trends

6. Installation of audio is nothing more than to create a good audio-visual environment, but vehicle modification of audio is not to say that the light is good, expensive is hard conditions! In fact, the vehicle itself is also to carry out some transformation, to rece the noise of the vehicle, to ensure that the noise inside the car will not be too big! There is the sound itself! Due to the limitation of automobile working environment, it is difficult to install and use audio-visual devices in automobiles. First, in the process of radio receiving and transmitting, the radio wave intensity is unstable e to the influence of terrain, location, time, climate and other factors; Second, the interior space of the car is too narrow, the windows and interior components form a disordered environment of sound, and the position of the passengers relative to the horn is unbalanced; Third, the higher the sensitivity of radio reception, the higher the authenticity of sound characteristics, and the electrical noise emitted by automobile electrical devices will be easily accepted; Fourth, e to the influence of heat and radiation, the performance of components is unstable; Fifthly, the vibration and impact of the car can easily cause the distortion and distortion of the CD. Therefore, the audition equipment installed in the car should have the following special requirements: (1) DC power supply should be used. The power supply of the car audition device is the 12 V battery on the car, so it must use direct current 2) The anti-jamming performance should be strong. Because the ignition device of automobile engine and other electrical appliances share one automobile battery, it has great interference to AM / FM (amplitude molation / frequency molation) reception. Therefore, it is necessary to use wires and components with strong anti-interference performance. Generally, the power supply of car audio has a choke, and the enclosure must be isolated by a fully sealed grounding iron shell 3) The seismic performance is better. When a car runs on different roads, it vibrates a lot to the audio-visual device of the car. In order to make the components welded and assembled firmly, the pins should be bent and welded as far as possible 4) The antenna is external. In order to rece the interference of the car engine to the radio, the external rod antenna is generally used. When the antenna is damaged, the radio will not receive the radio 5) Dust proof measures should be taken. When the car is running, there is a lot of st, so the audio-visual device needs to be packaged to prevent or rece the impact of st 6) Choose heat resistant components. Due to the high temperature in the car, the audio-visual device is difficult to dissipate heat, so the selected components have better heat resistance and work stably 7) The acceptance sensitivity should be high. The car cab has shielding effect, and the car is running fast, sometimes far away from the transmitting station, so the receiving sensitivity of the broadcast is required to be high 8) Inctive tuning is adopted. In order to prevent the influence of vehicle vibration on tuning ring driving, inctive tuning should be adopted for vehicle radio 9) Low impedance high power horn is adopted. In order to obtain higher power, in addition to BTC mode, the horn uses 1.6 ~ 4 ohm low impedance high power horn and thick horn lead. The diameter of the horn is mostly 10-15 cm. Advanced car audio uses coaxial 2 dB or 3 dB 15 ~ 20 cm speakers 10) With luminous lighting function. When the car is driving at night, for the convenience of radio and playback, the keys should be equipped with light transmission lighting. The design of this lighting device should not affect the effect of LCD digital display 11) The volume requirement is small. As the car is limited by the internal space, the volume of audio-visual device should be designed as small as possible. Therefore, the choice of mechanical parts and electronic components, should use small, good heat dissipation.
