Budding scientists from across the state came up with an array of scientific solutions that not only looked promising, but also feasible.
Some of the 112 models put up by class IX to XII students of equal number of schools at the two-day state edition of the 41st Jawaharlal Nehru National Science Exhibition, which opened in Ranchi on Thursday, looked both inspiring and innovative.
Hosted by the state HRD department at Ranchi Zilla School grounds, five models were selected from each of the 24 districts during the district round held earlier. Thus, as many as 120 models were expected to be displayed. However, only 112 schools registered for the state-level contest.
The students offered solutions in five categories — resources, energy, health, agriculture and environment.
While models on popular topics like water conservation, organic farming and eco-friendly house were plenty, a few students pondered over more innovative concepts.
For instance, Deepak Kumar of Simeria High School in Chatra thought of trapping lightning to meet the energy requirement of the state. He exhibited a model, showing how the project would work.
Similarly, Tahid Alam of SS High School of Kolebira in Simdega district floated the idea of a bat-friendly garden to protect the endangered species.
Satyajit Roy of Dumka Zilla School and his friends showed how electricity could be produced from a walking on a mat. “So much power is generated when people walk on a mat that it can be used to light lamps,” said the boys.
Though the idea of producing energy from piezoelectric tiles is already known, these boys are not aware of it.
Another innovative idea was presented by Nikhil Parasar of St Xavier’s School, Hazaribagh.
He displayed an alternative fusion energy tower, showing how waste water from toilets could be used to run a hydraulic lift in an apartment. He also proposed to put small wind-run turbines atop buildings to supplement energy.
“This is a unique idea and must be tried out”, said Osama Akhtar, a visitor from Angel’s World School in Ranchi.
