The future: putting solar energy on the body to generate electricity

Hydrogen energy vehicles with zero pollutant emissions, mobile navigation technology with sub-meter level of accuracy, solar energy clothes that can be worn on the body, top instruments that can map the brain... These great technologies and products come from a common "family" ————Wuhan Future Science and Technology City, more than 1,000 technical patents were born here.

Recently, the third event of “Millions of College Students Seeing the Light Valley” jointly organized by the newspaper and Wuhan East Lake New Technology Development Zone was held in Wuhan Future Science and Technology City (hereinafter referred to as “Future City”). Dozens of students from Huazhong University of Science and Technology Walking into and understanding the future city, I am amazed that these technology patents are affecting and creating the lives of people in the future.

Transportation: Hydrogen energy vehicles will achieve zero pollution emissions

The orange bus ran up in the factory and there was no exhaust or noise at all. If it weren't for its orange-red appearance, the students who came to visit would not notice how the bus differed from the bus in Wuhan.

Soon, the students found the answer on the body: "Normal temperature and atmospheric pressure hydrogen storage · Thai song hydrogen energy car", this is a new energy car different from electric cars.

Hydrogen is a kind of gas that can be burned. It produces only water after burning with oxygen, without any pollution. Hydrogen energy is a clean renewable energy source with high energy density, which can be widely applied to various power equipment in theory. At present, hydrogen energy vehicles have become an important direction for the R&D and industrial layout of Japan, South Korea and Europe, but it is difficult to store at room temperature and pressure. This is a worldwide technical problem.

On September 17 this year, Wuhan Institute of Geological Resources and Environmental Industrial Technology successfully broke through this problem and developed the “normal temperature and atmospheric pressure hydrogen storage technology”, which makes the future hydrogen energy vehicles as convenient as adding gasoline when adding liquid hydrogen. .

This is another top technology in global innovation developed in Wuhan Future Technology City. Optical communication chips, 20,000-watt fiber lasers, normal temperature and atmospheric hydrogen storage technologies, etc., at least seven top-notch patent technologies break international monopolies and fill domestic gaps.

According to the relevant person in charge of the Wuhan Institute of Geological Resources and Environmental Technology, the institute and a number of units have developed an application path plan for “first bus, re-logistics, and then passenger cars”. It is reported that in the first half of next year, the first batch of normal temperature and atmospheric pressure liquid hydrogen storage buses and logistics vehicles will be put into trial operation in our province.

Travel: high-precision navigation error as low as 1 meter

Using mobile phone software to take a taxi has become the most common way of transportation for people. “Mobile navigation shows that the driver is near the passengers. Our location is only 20-30 meters apart, but we can't find each other.” This has almost become a phenomenon that every driver and passenger of the network will encounter.

In the Future City's Wuhan Navigation and Location Service Industrial Technology Research Institute, the students who came to visit are full of curiosity about the high-precision satellite navigation technology that can solve this problem.

Assistant General Manager Qin Jing introduced that the institute has developed a high-precision OEM board, which is the most important part of high-precision GNSS receivers. After it is connected with the Beidou navigation satellite, it can subtly perceive the spatial position change of the object with an accuracy of millimeters.

"This technology has been tested by relevant national laboratories and is the most advanced result in terms of domestic precision. Compared with the world's top high-precision satellite navigation technology, it does not fall." Qin Jing pointed to the sample of the exhibition hall. .

Qin Jing described that using the high-precision satellite navigation technology of the hospital, a high-precision position navigation positioning chip or module is implanted in the mobile phone. The mobile phone navigation can not only give accurate orientation, but also narrow the navigation error to Within 1 meter or even smaller, it is easy for drivers and passengers to find each other.

It is understood that this technology will not only be used for civil navigation, in agricultural production, relying on high-precision satellite navigation technology to help agricultural machinery accurately measure crop spacing, plan sowing harvesting routes, guide machine intelligence and automatically complete the sowing of crops and Harvesting, turning traditional agricultural cultivation into real uncultivated.

Life: flexible solar cells can be sewn into clothes

In the solar application scenario, the first thing people think of in the mind is the large and square solar panel placed on the open space, which is more laborious to move. When visiting Wuhan Meige Technology Co., Ltd., a piece of flexible solar cell with curved and folded pieces subverted the concept of solar panels for college students.

The flexible solar cell is a fist product developed by Wuhan Meg Technology Co., Ltd. The company relies on 48 international and domestic patent technologies to develop a foldable solar cell. It is silicon-free and glass-free, and can be applied to products of various shapes to change shape at will. This type of battery sheet is greatly expanded due to its flexible and flexible folding and lightweight features.

A flexible solar cell with an area of ​​only A4 paper covers the outside of the backpack to receive sunlight, and it takes only one and a half hours to fill an iPhone6 ​​phone. According to Cai Shuangshuang, the company's deputy general manager, the product can be placed on the roof of the car, on outdoor backpacks, on tents, in clothes, on people, and so on. "As long as there is light, it can generate electricity."

What is more popular with consumers is that the current global products, including solar cells used in satellites, generally have a solar conversion rate of more than 10%, and the company can achieve 24%, which is the industry leader in the world. Only the company's outdoor backpack flexible solar cells, in Taobao.com created 45 days to sell thousands of sets of performance.

It is understood that Meg Technology will continue to research and develop, trying to reduce the thickness of solar cells to 1 mm, reduce the weight of one square meter of solar cells to 500 grams, and reduce the cost of power generation from 1 US dollar per watt to 1 cent.

Medical: brain detection, with or without disease

In the Wuhan Institute of Optoelectronics Technology, I saw a brief introduction of a company on the propaganda wall. The students were very kind. Many companies on the wall were involved in the participation and support of experts and professors from Huazhong University of Science and Technology.

The most well-known story is that in 2013, the “microscopic optical slice tomography system” (MOST) invented by Luo Qingming, vice president of Huazhong University of Science and Technology, was listed on the Wuhan Optics Valley United Assets and Equity Exchange and was awarded by Wuhan Woyi Biotechnology Co., Ltd. The purchase of 10 million yuan has become the biggest technological achievement in the transformation of the central government in the Han Dynasty since the introduction of the “Golden Ten” in Wuhan in 2012.

According to reports, through this device, the distribution of nerve structures and blood vessels in the brain, whether there is disease or not, is known. In 2013, MOST captured the high-resolution mouse brain 3D map for the first time in the world, becoming the world's top brain scientific research instrument.

MOST works like a satellite to the Earth for panoramic scanning. The spatial resolution accuracy is sub-micron, less than 1/60 of the thickness of a single hair. Using optical imaging, not only can local neural connections be seen, but also three-dimensional "highways" and "railroads" that construct neural networks can be observed throughout the brain.

It is understood that many diseases in the world may be caused by the "fault" of the neural circuit. I hope this research can further promote human understanding of diseases such as depression, Parkinson's disease and Alzheimer's disease.
