Suprio Das : The unsung revolutionary scientist

MR. Supriyo das

Let's meet an unsung revolutionary. He is inventing revolutionary devices for poor and downtrodden people of Society. Quite less reported scientist- Mr. Suprio Das. He works selflessly, having ditched so many flowery, cushy job offers to what he loves most- putting in research to invent/develop low-cost, affordable devices for masses...... Putting here detail of one of his innovative devices- ZIMBA- http://www.thebetterindia.com/5089/tbi-innovations-zimba-a-simple-machine-to-quench-the-thirst-for-clean-water
Some description of the device from the site-
"An affordable device that does not need electricity or moving gears but runs only on gravity, is scientist Suprio Das’s answer to water contamination."
"In the year 2005, the presence of arsenic in Kolkata’s ground-water caught Das’s attention. He began visiting small villages in Bengal to collect water samples. He then volunteered to work with a local NGO on arsenic mitigation. In 2011, his invention, ZIMBA, an automated chlorine dozer, was installed in a village near Gobardanga, Bengal and consequently in five slums of Dhaka this February"
"How does ZIMBA work? Once installed, it automatically adds chlorine to water in correct proportions, explains Das. It can be fitted to a rural community’s existing water source, such as the hand pump of a well or the tap of a rainwater harvesting cistern."
"Deriving the correct ratio of chlorine to water, a common problem for most people working with chlorine, required precision and the creator of ZIMBA achieved it after much hard work."
"When asked about funds for the project, Das, who gave up a stable career in electrical engineering to innovate independently, says, “It is not just raw material but also tools and manpower that are required for experimenting and prototyping. I start with my own resources and then look for funding to move ahead. Projects die when funds are not available but for ZIMBA I was fortunate to get some funding from a US-based organization.” The relative cost of the device when patented, Das tells us, can be approximately Rs 5000 and one unit can serve more than 50 families. If produced in bulk the cost can be brought down by 50 per cent."

YUVA REVOLUTION salutes him for his dedication and noble works.
