ADA, known as IDA coin in Chinese, is the proct of Cardano project. Cardano project was launched in 2015, and its name comes from Italian mathematician Gerolamo Cardano in the 16th century. Cardano is a doctor, astrologer, philosopher and gambler. He used astrology to predict his death, and it is said that he finally committed suicide on the same day. ADA is named after ADA levea, a British aristocrat in the 19th century. She is known as the first programmer in human history
the total amount of Aida coins issued is 4.5 billion, and the planned financing scale is 60 million US dollars. The project is divided into four phases of crowdfunding. So far, crowdfunding has been completed
It will take about 24 years to proce three blocks per minute until all of them are released2. Mine card needs a certain amount of computing power. Generally, the computing power of a card is higher than that of N card at the same price
3. Perpetual motion machine is not in line with the law of conservation of energy, so it can not be done with solar energy or gravity!
4. Reason 1: there is a misunderstanding among the public
for the general public, the most common solar proct is water heater“ Laoguang has the habit of taking a shower every day, and the hot water consumption is large. It is reasonable to welcome energy-saving and environmental friendly solar water heaters. But this is not the case
in Guangdong, where the annual sunshine time is more than 2000 hours, the popularization rate of solar water heater is only 2%. According to Chen Pengcun, vice president of Guangdong Solar Energy Association, the current installation is mainly for schools, hospitals, factories and other collective users, with few indivial households
"it's mainly because of cognition." For example, he was worried that it would not work on cloudy days, and that the initial investment would be too large, Chen said. He said that this is a complete misunderstanding. Guangdong has a long sunshine time and a large amount of radiation, and only 60 to 80 days of cloudy days every year; Even in cloudy days, the solar water heater can absorb heat. If it is cloudy for a long time, it can also be used with electricity and gas
in addition, the use of solar water heaters is also very cost-effective. Take a family of three as an example. The initial installation cost is two or three thousand yuan, but after the installation, at least eight or nine degrees of electricity can be saved every day. More than 1000 yuan of electricity can be saved in one year, and the cost can be recovered in two or three years
the second reason: the management department is not active
in addition to energy saving, the use of solar energy will also bring huge social benefits such as environmental protection to the local. According to statistics, Kunming, the most mature city of solar energy utilization in China, can save 80000 tons of standard coal every year, rece 11000 tons of carbon dioxide and 445 tons of sulfur dioxide, becoming a veritable "Solar City"
with such environmental protection and energy saving, the utilization rate of solar water heaters in China has reached more than 10%, which is far higher than that in Guangdong. In Tibet, Yunnan and other areas with good solar energy conditions, the penetration rate has reached 30%; Even in Jiangsu, Zhejiang and other provinces where solar energy conditions are far inferior to Guangdong, the utilization rate is nearly 20%< According to the analysis of instry insiders, in addition to the understanding of users, the enthusiasm of local management departments is also the key. For example, in Kunming, the relevant departments have given clear guidelines for the installation of solar water heaters
and in Guangdong? So far, there is no clear plan for solar water heaters in Guangdong, let alone guidance or encouragement, Chen said. The reporter asked the relevant person in charge of the planning department of Guangzhou for confirmation, and the answer was: there is no such plan at present, so it is better for the public to consult or report to the nearest planning branch before installation. However, the reporter learned that a small number of retail investors who have been installed at present are basically "stolen" without declaration
the third reason is that the property management office of the residential area does not allow the solar water heater to be energy-saving and environmental friendly, but some residents who live in the residential area encounter another problem when they want to install it, that is, the property management office of the residential area does not allow it, because it "affects the appearance". Miss Zeng, who lives in a large building in Panyu, told this newspaper that she had planned to install the solar hot water pipe on her roof, but the property management department blocked it on the ground of affecting the appearance and threatened to cut off water and electricity
in fact, it is not uncommon that such interference at the property management site can not use solar energy. In this regard, the person in charge of a large-scale solar water heater factory in Guangdong also said that the community can be installed in a unified way, just like installing outdoor units of air conditioners, "it's also very beautiful.". But this person also suggested that the solar water heater should be installed in the new residential building, so that the style can be unified and the central heating can be provided. Each household only needs to install a hot tap, which is not only beautiful in appearance, but also cost-effective. "It's also a matching model for new housing in some cities in the mainland," he said

5. Today's smart phones generally have a battery capacity of 5V, 1200-1600mah, or 6-8wh watt hours
it can be used for four or five hours, with an average power of 1-1.5w. (if it can be used for 10 hours, the energy consumption is lower)
the solar cell as big as a smart phone is also more than 1.5W, so it's not the reason for the large panel
the main reason is that the light is not stable, there is power generation at one time and there is excess power generation at the other, so it is often shut down
therefore, if the power generated by the solar cell is charged to the lithium battery, the voltage will be stable, and it is not easy to shut down,
the excess power will not be wasted when stored
this is the solar charger on the market. It doesn't have energy storage. It works intermittently or ups and downs. It can't be used as a power supply directly on mobile phones

6. It has something to do with the nature of the enterprise, but it's no less than 3500. Of course, it should be able to program independently. If the nature of the enterprise is good, it's higher.
7. If you want to find a processing job, Kunshan is better. Because Kunshan is close to Shanghai. There are many processing enterprises. So there are more opportunities.
8. 1、 First of all, you should make clear the difference between the two units. The human resources and social security bureau is a government department and an administrative organ. Talent exchange service center is a service organization set up by the government, which belongs to public institutions and is generally under the leadership and management of human resources and Social Security Bureau
Second, to understand the purpose of archives, generally speaking, the most important thing of personal archives is to prove your length of service. Of course, there are other things, such as the resumes of civil servants, participating units, career editors and so on
thirdly, the talent exchange centers and human resources and social security bureaus in large places work separately, but their subordinate relationship remains unchanged. Small places, such as the county, are actually in the same office building, so there is little difference between them. Anyway, they all need management fees
the above is for reference only. I hope it can help you! thank you
