What is your favorite TED talk?
catone: I think it's probably this one: http://www.ted.com/index.php/talks/william_kamkwamba_on_buil..."When he was just 14 years old, Malawian inventor William Kamkwamba built his family an electricity-generating windmill from spare parts, working from rough plans he found in a library book."Though the actual interview is a bit awkward at times, I found his story to be very inspiring.
