We've been trying all weekend, in vain, to get hold of a clip of the most dramatic scene at last week's TED conference: the Kleiner Perkins partner choking up at the end of his talk on energy technologies. He was moved to tears by the danger to the planet posed by global warming, and by the presence in the hall of his environmentalist teenage daughter, who has been giving him a hard time on the subject. $100 by Paypal to the person that supplies us with video, no matter how blurry, of the touching scene. Anonymity guaranteed. [Photo by Pierre Omidyar.]
