Anil Gupta (teaches at IIM A) founded the Honey Bee Network - an organization which collects traditional knowledge and helps spread grassroots innovation throughout India. Gupta visits villages and talks to ‘barefoot inventors’ about their homegrown products, then cross-pollinates the ideas. Once linked, those solutions are distributed and commercialized for use elsewhere with careful attention to protecting and recognizing the work of the originator. Some projects: Bicycle Hoe, Micro-windmill Battery Charger, and Pedal-Operated Washing Machine.
