I've really tried to solve some big problems: counterterrorism, nuclear terrorism, and health care and diagnosing and treating cancer, but I started thinking about all these problems, and I realized that the really biggest problem we face, what all these other problems come down to, is energy, is electricity, the flow of electrons.
我一直在尝试解决一些大问题： 比如反恐，核恐怖活动， 还有医疗保健，癌症的诊断和治疗， 然而当我开始思考这些问题， 我意识到，我们面临的最大问题， 也是所有其他问题的根源， 是能源，电力，电子的流动。
