There was an initiative in the state of Kerala for bio portable toilets with solar powered light. I saw one or two in the Cochin city which uses a 1 rupee coin to open the door.
The problem with these initiatives is that they are all politically motivated. Once the ruling parties get the necessary PR around it, the funding is stopped. Modi is no different. There is no reason to laud Modi for this. The previous governments have also done this though with a less "catchy" names with no PR.
What I see and hear from the people on the field is that Narendra Modi is a show man with no stuff. Dashboard looks cool, but those toilets built are not maintained and is in the verge of wreck.
This has nothing to do with building toilets. Its with education. The northern parts of India has very low literacy rate. High literacy + HDI states like Kerala and Meghalaya was already clean. The dashboard of 2014 data proves that.
