The Indian village of Kattehole is a collect­ion of 34 mud-and-thatch houses in two tidy rows, a schoolroom, a Hindu shrine and a large banyan tree under which children play and men chat. Bangalore – the hub of India’s vibrant software industry – is 180km away, but the 200 people who call this place home have not shared in the city’s prosperity, and scrape a meagre living tending goats and cultivating vegetables.

Between them, the villagers of Kattehole have just three motorbikes to carry their produce to market, travel to a doctor, or reach the world beyond for any reason. Located several kilometres from the nearest power line, until recently the residents did not even have access to electricity and were instead dependent on highly-polluting kerosene-burning lamps.
