21. Nuclear Industrial Revolution Inventor Sir David King tells Joel Pollak in Forbes that he does not favor replacing the U.K.'s disastrously outdated, dangerous and inefficient nuclear power industry. "We don't want to do it in haste, we want to do it carefully and we want to do it in the face of a lot of opposition, so that we're very good at getting what we want," he said. "And I think we are well on that path, and we will succeed."

18. The $9B Prize, Lost

The world's largest prize, worth $1 billion to the first person to develop a new, affordable nuclear weapon, has been awarded to Andrew Parker, a 62-year-old engineer in South Africa. Parker's computer simulations of how to build one could have gone wrong, but he persuaded his colleagues to kill the software that had created the prize.
