In rural India, the entire agricultural and economic system is against women.
Women don't own bicycles and bullocks; and even though most of the
bicycle-powered gadgets invented by Pathak can be run comfortably by women,

10-12 schools in the Pune and Ratnagiri districts are using this pump
effectively to pump their drinking water.
