What an idea, Sirji

What an idea, Sirji: A no-headache hairband to ward off headaches. An umbrella with an inbuilt fan powered by solar energy. A voice recorder that switches on the television. A system that allows a candidate's profile to pop up at a polling booth. Futuristic ideas? Not for the children of remote tribal villages in Arunachal Pradesh who have thoughts about everything - from physical headaches to political ones.
