Using body heat to charge your phone? A new device invented by a student from the Nanjing University of Information Science & Technology has caused quite a stir online in #China. Lin Gang’s portable #mobile #charger is said to work using body heat. It essentially means that you can recharge your phone by just holding the charger in your hand. Lin claimed that with just that, you could charge your phone battery to 100% within two hours. Lin presented his #invention to the public at a #technology fair this week, and already says that a number of companies have shown interest in it. Lin said that his work was inspired by Ann Makosinski, a #Canadian high school student who created a body-heat powered flashlight in 2013. However, not all is hunky-dory for this young inventor. Most experts seem to believe that Lin’s claims are not based on sound physics. According to Lin, the device is based on thermoelectric concepts. He explained that electricity is generated from the temperature difference at the two ends of the device, i.e. the body temperature and the ambient temperature. Experts have dismissed that explanation, arguing that the temperature difference isn’t sufficient to generate the required voltage to power a smartphone. On Sina Weibo, most users were full of praise for Lin’s creativity, although they did share many of the doubts raised by the experts. “Always be positive. If it is fake, the inventor should be severely punished to avoid similar cases. But, if it is true, it will be great. I choose to believe it. It will at least encourage some people to invent new things. Those who despise the inventor, please stop!” @ranyishufengye “It conflicts with scientific theory. There should be an additional energy source.” @lizhaoshu. “So the inner power through hands from those Kung-Fu masters in Kung-Fu movies is becoming real!” @jiangyouduoqian.
