Chapter 1440 (1/2)
In Li Mu's view, with the explosive development of human science and technology, battery is a special field that has been hard to break for a long time.
People have been able to condense tens of thousands of tons of computer equipment needed decades ago into the size and weight of a book, and even the computing power has been increased by thousands of times. According to the development speed of computers, now a mobile power battery should be able to drive a two ton car for 2000 kilometers without stopping.
However, the reality is very cruel. The human technology tree has not found a huge technological breakthrough in the field of battery. All mobile devices are plagued by the specific capacity that battery can not break through.
Fifty years ago, how much energy can a kilogram of battery store? Now, the lithium battery has increased by several times at most. It's hard to improve the energy density of the battery. The notebook is equipped with a heavy battery, which can only store energy for a few hours. After more than ten years, the smart phone, which publicizes power saving, basically needs to charge every day. If we follow the development speed of the computer processing chip In the era of Apple mobile phones, the battery should be reduced to the size and weight of only one yuan coins at the same capacity.
It is precisely because the battery industry cannot find a major breakthrough that the service time of lithium battery will exceed everyone's imagination. We have been used to rapid innovation for a long time. Even contemporary scientists believe that in the near future, someone will be able to find a more advanced power storage scheme than lithium battery, but the terrible thing is that lithium battery, like rubber, has become Part of the industry that has always been irreplaceable.
Since the invention of automobile, there have been more than ten thousand technological innovations at home and abroad. People even try to get rid of the fuel tank and the fuel engine. But up to now, no car can get rid of the rubber.
The more so, Li Mu feels more and more that the layout of lithium battery industry should be grasped. While it has not yet become the mainstay of the information age, it is necessary to dig out the source of this industry.
Nowadays, people's life is far away from lithium batteries, and the popularity of mobile phones is not high, so not everyone can touch lithium batteries. But in the future, mobile phones, laptops, tablet computers, rechargeable batteries, cameras, even flashlights, small vibration toys, new energy vehicles, etc., can't leave lithium batteries. Before the advantages of the industry are highlighted, Put resources in your own hands!

As always in Harvard campus, as the academic palace, everything here follows its own rules very much, and there is no change. However, the inner Harvard has started to have some elements different from the usual. This is because in the body of Harvard, there is a very new baby. Its name is Facebook.
With Li Mu's funds, Mark Zuckerberg put most of his energy into the incubation of Facebook project. He has no great ambition. In the early stage of entrepreneurship, his greatest wish is to make Facebook popular in Colleges and universities across the United States and become the new favorite of American college students on the Internet.
In order to achieve this goal, Mark Zuckerberg has invested a considerable amount of energy and money to promote Facebook in Colleges and universities across the country. He and his local twitter team plan to travel all colleges and universities in the United States in the next three months, and push Facebook, a new social product for college students.
When Li Mu arrived at Harvard, Mark Zuckerberg just came back from New York, and his team was working in turn at Columbia University and other universities in New York. Because there were so many universities in New York, Mark Zuckerberg attached great importance to it. Before that, he had been staring at New York for more than a week. This time, Li Mu said he would meet himself at Harvard Face, he just hurried back to Massachusetts.
In Mark Zuckerberg's eyes, Li Mu is his boss, so as soon as he arrived at Harvard, he directly came to see Li Mu, who was very excited to report the current development of Facebook to Li Mu.
According to Mark Zuckerberg, at present, Facebook has millions of registered users, more than 100000 daily users, and more than 90% of the users are college students. This is not only because the focus of publicity is on the university campus, but also because college students have more time to contact the network, and there is a great demand for social networking on campus.
Li Mu asked him, ”how many college students are there in the United States now?”
Mark Zuckerberg said without hesitation: ”at present, the total number of all undergraduate and graduate students in the United States is about 17 million.”
Li Mu nodded and said, ”you now have millions of registered users, accounting for 6% of your total target group in the first stage. It's a long way to go.”
Mark Zuckerberg said: ”although it's only 6% now, at our current promotion speed, it can be increased to 30% at most by the end of the year.”
”In about half a year, from 6% to 30%, it's a linear growth,” said Li, with his chin on
Mark Zuckerberg didn't understand the meaning of Li Mu's words, but vaguely felt that Li Mu might not be too satisfied with his goal, so he tentatively asked him: ”President Li, if you have any opinions and unsatisfied places, please point them out directly, and I will try my best to correct them.”Li Mu smiled and said, ”don't be too nervous first.”
After all, Li said slowly, ”in the Internet, good product users are growing linearly. Starting from 10000 users, they have crossed 50000, 100000 and 200000 levels, and have grown to millions, tens or even billions.”
