A few months ago, William Kamkwamba spoke at MIT as he wrapped up a speaking tour of the US with coauthor Bryan Mealer. This video is the whole evening’s presentation, and includes the introductions and question/answer session afterward. William starts at around 11 minutes.
The talk was sponsored by MIT’s Technology and Culture series and he was introduced by Amy Smith of D-Lab. There is a brief segment in the evening on Moving Windmills, a documentary film about William and his story. The Boy who Harnessed the Wind is an excellent and inspirational read that makes real the importance of supporting local makers around the world.
