Choti Devi (left), aged 63, harvests Bengal Gram from her field in Balaji ki Dhani, Bauli, Nagaur District, Rajasthan, together with hired labour. Barefoot solar engineer Santosh Devi who graduated from a  solar course in the Barefoot College in Tilonia, Ajmer, Rajasthan, India, had provided Choti Devi with solar power and lanterns improving her life by allowing her to protect herself from poisonous monsoon insects and work late in the fields, cook in the night, and protect her cattle when they return from grazing after sunset.
