Necessity is indeed the mother of invention. From Motihari, Bihar, comes the story of Mohammad Saidullah, who was annoyed because the boats that went to his village were overcrowded. As a result of this, he was unable to go back home and meet his wife on time. Saidullah thought he must do something, and went on to make an amphibious bicycle that worked on both water and land. This isn’t the first time he’s invented something. His other inventions include a mini tractor, a key operated table fan, and a mini turbine for the generation of electricity. And you know the best part? He names all of his innovations after his wife — Noor.
