In the summer, under the poisonous sunlight, even if holding an umbrella, it still feels hot and unbearable when going up the street. Some people may have imagined that it would be nice to have a fan or even an air conditioner. Can this really be achieved? A group of elementary school students thought of it. On the morning of the 11th, "Beautiful Chinese Campus Charm" 2014 Changchun District Campus Art Exhibition in Chongqing Huilong Primary School was held in People's Square. The children had some fantastic ideas and made them full of praise.
Solar umbrella attracts crowds onlookers
On the 11th, Xianlong Primary School, Guangfa Primary School, and Fandian Elementary School also participated in this “Beautiful Chinese Campus Charisma†event, bringing together many parents and students. In addition to talent shows, some children also "invented" some bizarre things, the idea is amazing.
In the fifth grade of Huilong Elementary School, Chen Hao, Zeng Yanjun and Xiao Youhao designed a solar umbrella, which caused many parents to watch it. They installed solar panels on an ordinary umbrella, which could even bring a small fan on cloudy days.
Took this “solar umbrella†and installed four flexible solar panels on the top. The top of the umbrella was cross-shaped and a small magnet was fixed on the opposite side. The wire connecting the four panels protrudes from the opening in the top of the umbrella to connect to a USB connector, and then connects to a small red fan that keeps turning.
This umbrella has little difference in weight compared to an ordinary umbrella, and no battery is installed.
This umbrella can also charge the phone
Chen Hao said that their original idea was to solve the issue of mobile phone charging when they were out. After testing, even though yesterday was a cloudy day, this solar umbrella can still provide nearly 6 volts, enough for mobile phone charging.
The solar umbrella is still an umbrella. When it rains, will the electronic components wet and cause a short circuit? Several small designers look confident and the flexible solar panels they use are waterproof and can bend to a certain degree.
Although the idea is good, does this umbrella have any commercial value? Many adults on the scene are also very interested in this umbrella, but some people ask questions: What is the cost of such an umbrella?
"More than 1,000." One of the children answered. Another child hurriedly corrected it. "There are only three hundred."
Some people say that in terms of cost, commercial value is not big, but you are new to creativity. "Maybe someone can design a cheap and practical solar umbrella?" one parent said. (Reporter Zhang Liang)
