More than 63% village people are deprived from the continuous electricity and students suffer the most. On the other hand, few family of this kind of village, use Solar panel for electricity but they don't use the solar electricity only for their children's study purpose, so, students have no other option but to use lantern for their study. To reduce this problem, we can substitute lantern with the renewable energy source by which students won't worry about light at night. To solve this problem, a project called "Digital Harican" had been proposed in a competition, known as "Eak Idea te Bajimat-2017" powered by Ministry of power, energy, resource and minerals. Under the ministry of power, energy, resource and minerals this national wide competition took place and they selected 30 innovative ideas. On 21st March, 2017 in the final round among the 30 ideas Digital Harican won the 1st runner up prize. Digital Harican project was proposed by S.M Mahfuz and Md. Tasjidul Islam, the two 3rd year students of Department of Economics of Bangladesh University of Professionals. Their Team name was Char Chokha. The main concept of their idea is to make a solar system based school bag for rural students from which the bag will produce light and assure their study at night. S.M Mahfuz received the prize on the behalf of Team Char Chokha from State Minister of Power, Energy and Mineral Resources Mr. Nasrul Hamid.
