In remote rural areas in India, 18 million people suffer isolation and poverty due to their inability to work. In this audio interview, Jennifer Roberts, associate editor of the Stanford Social Innovation Review, converses with D.R. Mehta, whose NGO gives mobility to 20,000 people a year through the fitting of a high-tech prosthetic limb known as the Jaipur Foot. Mehta discusses the genesis of his organization, which makes the prosthesis freely available to the poor.
