14 -Year -Old Tejaswani Invented the "Air Bike"
14-year-old Tejaswani from India invented a bicycle that propels on air. Without pedals or any use of fossil fuels, the “air bike” can run an astonishing 60 km on just 10 kg of compressed air. Tejaswani first conceived the idea when she was at a bicycle-repair shop. She saw how the mechanics were using a simple air gun to detangle knots in a bicycle tire. Her invention has captured the eyes of scientists who are looking for solutions to fight air pollution. She carried out experiments to develop this new eco-friendly technique that can also be used by disabled people.
