Every time you do a Google search or charge your phone, some ice caps far away will melt a little and this planet dies a little more. To stop the death of the earth and the death of humanity, the race is on to find clean power generating technologies. So how about a power generator the size of a book that powers four Indian homes, saves money, has no emissions and saves the environment? Such a small power generator already exists and is called Bloom Box. The pioneer behind it is R S Sridhar. He has a bachelor’s degree in mechanical engineering from the NIT at Tiruchirappalli, and an MS in nuclear engineering along with a PhD in mechanical engineering from the University of Illinois. Sridhar stuck on the idea for Bloom Box when he was working as the director of Space Technologies Laboratory at University of Arizona. He was asked by NASA to make reactor cells that could generate oxygen for astronauts to breathe on Mars. When the Mars project was cancelled, Sridhar got the idea that his concept of making oxygen and hydrogen can be reversed to generate power by sending oxygen in as opposed to out of the cells. While today Bloom Boxes are powering some of the biggest companies, Sridhar expects homes to have their own brick-sized power generators within 10 years.
