Indian student Rajesh Adhikari builds shoe that can charge phones as you walk

Last month we came across reports about a 15-year old boy who built a 3D printer, and now we have this:  A 12th standard boy has created a shoe that can charge mobile devices as you walk. The boy concerned has been identified as Rajesh Adhikari from Nainital, and his shoe takes complete advantage of the energy generated when a person walks, in order to charge a mobile phone.   According to a report by ANI, the idea of making such as waterproof charger struck Adhikari when it snowed heavily at his home town, leading to a power blackout. He had built the device to ensure that in such times, one could charge phones at least for basic communication. But this also means users will have to walk enough to charge the device. A new good reason for exercise perhaps!   Talking about the shoe-mobile charger, Adhikari told the news agency, “When we raise our feet, the spring gets released and the dynamo starts revolving, which generates current. We can charge our mobile phones while we are walking.”   The charge can be reportedly used to light a bulb as well, in case of electricity failure. One simply needs to install a battery in the shoe for lighting a bulb. Adhikari also plans to add further improvements to the shoe. He is now reportedly working on a design that will make the shoe a wireless phone charger so that the user can charge a mobile phone by simply walking with it in his/her pocket.   Adhikari is not the only Indian low cost tech entrepreneur though.   There is also the story of Angad Daryani - 15- year old dropout-turned-entrepreneur – who is believed to have built India’s first 3D printer using DIY kits and wants to bring 3D printing to every household. Daryani had a keen interest in technology from a very young age and built his first humanoid robot when he was just eight-years-old. He built a remote-controlled hovercraft in Class 6 by watching YouTube videos. By 13, he was building his own versions of the open source RepRap 3D printer.
