While the profit motive behind invention and innovation has always been there, it's not just big sales of consumer products that inspire inventors. Many want to use their creativity to promote social equality and invent for "a greater good." In the first of several podcasts examining this concept of social entrepreneurship, we speak with Michael Callahan who, even at the beginning of his career, knows this is the field for him.


"Prototype Online: Inventive Voices" is a production of the Smithsonian's Lemelson Center. Written and hosted by Paul Rosenthal. Audio production by Benjamin Bloom. Theme music by Will Eastman. Art Molella, executive producer. Michael Callahan was interviewed on 3 May 2007 by Paul Rosenthal. Podcast released 15 November 2007.
