Engineer RA Mashelkar shares three stories of ultra-low-cost design from India that use bottom-up rethinking, and some clever engineering, to bring expensive products (cars, prosthetics) into the realm of the possible for everyone.

Using a principle he calls “convex lens leadership,” R.A. Mashelkar’s vision has catapulted india’s talent for science and innovation onto the international stage.
