Prime Minister Narendra Modi had a meeting recently with heads of the country’s scientific organisations. The PM was keen to know about research on the latest technologies that will be released soon. One senior scientist said his unit has been working on technology to save energy in factories for the past three decades and will soon release a prototype product. Impressed with their achievements, the PM suggested that they should apply their expertise to solve some of India’s more basic problems. For instance, building toilets on the coast for fishing communities. This has become next to impossible because of water-logging.
