The shy boy who barely spoke English when I first met him in Arusha two years ago (and had this impromptu on-stage conversation with him http://bit.ly/9Q3l ) gave an amazing interview on Jon Stewart last night. Everyone at TED salutes him.
You can learn more about William and his astonishing story of building a windmill in his home village in Malawi here. His book is storming the charts at Amazon here http://bit.ly/IDJgf (A special call-out to TED's Tom Rielly @trielly who urged me to bring him to the stage at Arusha and who has since been supporting his education and much more. Also to @emeka_okafor who brought William to Arusha as a TED Fellow.)
