Examples for innovative ideas which helps rural india

[issac newton]

I am an ECE. I just need to know precisely about Innovative engineering designs that caused the development of rural India. It should have created a revolution by solving the common man's problem. Give me 10 to 15 examples of such innovations produced. Please refrain from giving me examples like telephones, etc.I need some very new kinda device created applying the engineering principles we study.

There can be n number of approaches to these problems and the device cannot obviously eradicate the problem completely. That is why i am confused like how such devices are created. Few examples will clarify my doubt .thank you.

I found this to be innovative:

Taking a ni-cad battery to power a fan which increases wood burn efficiency by blowing air into the furnace... and using the heat to cook, and the incoming air across a thermoelectric generator plate to recharge the battery and other devices via USB such as phones...utilizing the electron flow from hot to cold. Very good idea! I am contemplating building a candle powered charging device of similar nature.
