A 14-year-old girl from the state of Odisha, Tejaswani Priyadarshani, has come up with an innovative bi-cycle that propels on air.Without pedals, the “air bike” can run up to 60km on just 10kg of compressed air pumped into a cylinder mounted on the bicycle carrier.
The innovation holds importance at a time when world leaders are coming together to cut down on the use of fossil fuels derived from natural resources such as coal, oil, gas, petrol and diesel.
“Fossil fuels are produced from old and dry plants and animal remains. They are used in vehicles, industries and for firewood” said the class-XI student of Saraswati Shishu Vidya Mandir of Rourkela.
Tejaswani first concieved 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 tyre.
“I thought if an air gun can do that, it could also run a bicycle. I discussed my idea with my father who encouraged me a lot and helped me out with equipment to carry out experiments,” said the teenager.
The duo conducted many experiments on bicycles at their home. They bought an air tank with an inlet for filling air. It was fitted with a measuring dial, a starting knob and a safety valve to release excess air.
When the knob is turned on, the air from the cylinder is transferred to the air gun placed near the paddle that rotates the gear with the help of six different blades thus setting the bicycle in motion.
