This is a good example of why necessity is the mother of invention.
Virendra's workshop, which started in 1981 by manufacturing iron gates and grills, situated just opposite a school. Since they face frequent power cuts, Virendra had to install a generator that resulted in noise and air pollution, which affected school children and neighbors. "It was difficult to move to a new location for me so I started thinking about ways to control this pollution," says Virendra.
This was when he thought about something that could control the pollution and finally he come up with a device that can be attached to a generator or other diesel engines to minimize the noise and smoke, reports Manu A B from Rediff Business. It took him six years of experiments to build the first device. Initially, what started as a mission to carry out his work smoothly, turned into a successful innovation with universal appeal and value.
A patented device, it allows carbon deposits to get collected periodically. This can be reused as raw material for shoe polish and local small-scale industry units. Virendra Kumar is now fine-tuning the device to further reduce noise emanating from engines. His next project is a pollution control device for four-wheelers.
