Exciting future possibilities described by Michio Kaku

A decade or so ago, Michio Kaku, professor of theoretical physics at the City College of New York, interviewed a bunch of scientists about the subject of their research and it's potential impact in the future. He collected his findings and extrapolations in a book called Visions: How Science Will Revolutionize the 21st Century. This talk was delivered in 2009 and addresses many of the subjects covered in that book with a fresher perspective.
