In India's vast hinterland, life still rises and sets with the Sun. If solar power can be made to do what grid power has not been able to, the advantages are obvious and many — children can study well, women can organise their work better, people need not choke on kerosene fumes. There are, other less realised but critical advantages too — people can see, and avoid, scorpions and snakes or a small refrigerator can store life-saving drugs, especially antidotes for snake-bites. After all, snake bites claim a staggering 50,000 lives every year, mainly in India's hinterland.
