A very full show this week, and a day early. We start with some new athletic technologies that might be on display at the Summer Games in Beijing. Then, we hear about how Pakistani nuclear scientist A.Q. Khan might have sold digital blueprints for a nuclear weapon to interested parties. Then, a sequence that highlights Honda's fuel-cell vehicle, the Tata Nano from India, and a Zeppelin for a new millennium. We end with Paul Otlet's proto-Internet, and what's believed to be the first ever computer generated music. Great fun.
