Jignyasa, a national-level science model competition, that began at Nehru Stadium in Hubballi on Wednesday is attracting students and science enthusiasts in large numbers.
The second day of the national-level event saw students lining up in fron of the venue to have a look at the various science exhibits.
As they moved on watching the various models, the contestants enthusiastically explained to them the basic concepts on which their models worked.
More than 400 students from 18 States have taken part in the event and over 150 models are displayed.
The models are based on different concepts in physics, chemistry, biology, mathematics and also those regarding conventional and non-conventional energy sources.
Among of the highlights include models on converting mechanical and wind energy to electrical energy, innovative water pump and manual grinder, wireless energy transfer, automatic agriculture pump for drawing water, fire-resistant structure, wind mobile charger, production of electricity from waste, solar cycle for generating power, vertical car parking system, multipurpose power generation, farmer-friendly solar three-in-one farm equipment.
Roshan Pinto, a teacher from Bantwal in Dakshin Kannada, displayed a wind mobile charger made from a DC motor, a small wind turbine, a stand regulator IC and a mobile charger.
Mr. Roshan, who spent Rs. 200 on the model, said the model will provide low-cost portable, continuous energy. The innovative cycle pump of Prathyush A. Heebbar of Sudana Residential School, Puttur, was the centre of attraction at the exhibition.
The pump designed using an old bicycle, cycle pump and valves can pump water to an overhead tank using mechanical energy.
According to the organisers over 5,000 persons, mainly students, have come for the event so far and the overwhelming reaction was that such events were necessary to motivate students to come up with ideas that might be helpful to the society.
In addition to the exhibits, the students have been provided a platform to showcase their talents during the event.
