Good news for all who are tired of power disruptions during mobile phones battery charging or searching for charging points in places like rural areas.
A school student of Patnagarh has found the solution to the difficulty in neem leaves.
In a circle-level science exhibition of school students of upper primary and high schools at Bongomunda in Balangir district, a student designed a project to charge mobile phone batteries using neem leaves. Sonali Priyadarshani, a student of the Girls' High School, Patanagarh, charged the batteries by simply placing neem leaves in the middle of the electrodes, which connect the battery.
A number of interesting exhibits were put for display during the three-day science exhibition, held at Bongomunda from December 16 to 18. A total of 76 science projects from 20 blocks of the Balangir and Subarnapur districts were exhibited on the occasion.
Balangir, which is known for drought and its aftermath, is a reservoir of talent at the primary and high school level. Another student of Class IX had designed a project called "the third eye", which automatically switches the headlight of a vehicle to dip mode when light from another vehicle falls on it. The light reverts back to its original light intensity once the other vehicle passes away. Moreover, other lights on the right side of the vehicle also light up at the same time for the convenience of drivers and passers-by.
Irrigation using Tenda, a traditional method of lifting water from a well using two logs with a bucket tied at its end, is a common feature in the rural areas. Bharti Kata, a Class VI student of Model Upper Primary School, Gohirapadar in Bongomunda Block prepared a model of the Tenda using a plastic bar, filled with water and showed how water could be fetched much more easily from the well. "A valve has been fitted at the bottom up of the bucket allowing the water to pass into the bucket without any extra force to dip the bucket in the water," explained Bharti.
Speaking at the valedictory function of the science exhibition at Bongomunda on Tuesday, district Collector RS Gopalan appreciated the quality and variety of science projects displayed by school students and hoped that more and more students would bring their innovative science projects in forthcoming years. He also assured to take necessary steps to encourage students displaying excellent science talent. And the prototypes of the some of the excellent models would be developed, added Gopalan.
