Automatic chlorination on TEDx

Excellent TEDx talk by Indian engineer Suprio Das, inventor of the ZIMBA, an automatic chlorination device for disinfecting drinking water. Stanford and ZIMBA are collaborating to test out the ZIMBA in urban low-income communities in Dhaka. Some devices have been installed for over 1 year - each one has treated over 1 million liters of water.
