很多人都梦想有件哈利波特那样的隐形斗篷,三名来自南京航空航天大学光学专业的毕业生让这一梦想成为现实。
A one-person solar car that can be transformed into an electric moped, a door light powered by opening and closing a door and a cloak of invisibility are three innovative inventions recently created by college students.
最近,三项由大学生自主研发的创新发明揭晓,它们分别是:可变成电动助力车的单人驾驶太阳能汽车;用开门关门时产生的能量供电的“自发电”门灯;以及一件神奇的隐身衣。
Here comes the sun
太阳能汽车
The 100-kilogram blue solar car invented by 10 students at Southwest University’s College of Engineering and Technology in Chongqing has a top with four solar panels that charge the battery that powers the auto. Its speed is between 30-40 kilometers per hour and when fully powered the car can be driven as far as 50 kilometers.
重庆西南大学工程技术学院的十名学生发明了一辆重100公斤的蓝色太阳能动力车,该车顶装有四块太阳能电池板,收集来的太阳能作为汽车动力来源。该车时速达30-40公里,每储满一次能量,可最多行驶五十公里。
"The car is easy to drive. A person without any driving experiences could learn to use it in several minutes. It fits for campus and the golf course," said He Daijie, the leader of the invention team and a senior at the college. Or if one prefers it can be turned into moped scooter, he said.
该研究小组组长、大四年级学生何代杰表示“这辆车操作简单,没开过车的人,几分钟就可学会。适用于校园、高尔夫球场,当然了也可以当自行车用。”他还介绍说,如果愿意这辆汽车还能变成一辆电动助力车。
Seeing the light
“自发电”门灯
Four students at Shenyang University of Technology in Liaoning Province invented a door light powered by electrical energy produced by opening and closing a door.
来自辽宁沈阳工业大学的4名学生发明了一种门灯,靠的是开关门时产生的能量供电。
When people open or close a door, the door produces mechanical energy that could be turned into electric energy. After numerous tests for several months, the students fixed a joint lever above the door that connects the door and a speeding gear case to drive a generator attached to the door and send energy to storage cells. The storage cells provide electrical energy for the light.
人们开关门时,门所产生的机械能可转化成为电能。经过几个月的反复试验,这些学生在门的上方安装了一个连接杆,把门和一个加速齿轮箱连接起来,从而带动门上的发电机运转,并把能量传输到储电池里。接下来,这个储电池就给门灯供电了。
A college student’s dorm door is opened and closed about 60-100 times a day, which could produce 160-280 milliamps of electric energy. It takes 160 milliamps to keep a light working for at least 10 hours, said Xia Yingbiao, one of the invention team members and a mechanical design and manufacturing and automation junior.
该研究小组成员之一、机械设计制造和仪器自动化专业大三学生夏应标表示,一间大学生宿舍的门每天大约反复开关60-100次,可以产生160-280毫安的电量。160毫安的电量就可以让一盏灯维持至少10小时的工作
If light-emitting diode (LED) lights were used with the invention at all entrances in Shenyang schools, about 700,000 kilowatt hours a year would be saved, the team said. The university is applying patents for the invention.
该小组表示,如果把沈阳所有学校的“安全出口”LED指示灯都换成这种自发电门灯,一年就可节省约70万度电。目前,沈阳工大正在为这项发明申请专利。
Invisibility cloak
隐形斗篷
Many people daydream of an invisibility cloak like Harry Potter’s and three graduate students in optics from Nanjing University of Aeronautics and Astronautics have actually invented one.
很多人都梦想有件哈利波特那样的隐形斗篷, 这不,三名来自南京航空航天大学光学专业的毕业生让这一梦想成为现实。
Special Ferro-electric materials on the cloak reduce the scattering of light of an object wrapped with the cloak, and thus making the object "invisible," according to Li Peining, one of the three students.
三位发明者之一的李培宁解释说,斗篷上附着一层特殊的铁电体材料,披上斗篷后,由于光在物体上的散射减少,从而使得物体“隐形”。
"There are many invisibility cloaks based on various theories, but their light frequencies are different because there are some limitations on the frequencies. Our cloaks can control all kinds of light frequencies by adjusting them, making the cloaks more widely used," said Li Peining.
李培宁说:“利用各种物理原理设计的‘隐形斗篷’已出现很多,但由于光线的频率是不同的,过去的发明都有特定频率的限制。而我们设计的‘隐形斗篷’,可以通过调节光线频率达到自由控制各种频率光线的效果,从而使‘隐身斗篷’得到更广泛的使用。”
