Environmentalists get in the way. They often ask the right questions, but they're chasing the wrong answers - often hypothetical or uneconomic solutions.

There are no right answers to wrong questions.

Ask the right questions if you're to find the right answers.

An expert knows all the answers - if you ask the right questions.

Religion asks you to believe things without questioning, and technology and science always encourage you to ask hard questions and why it is important in science and technology. So I was always interested in science and technology.

And what I wanted to do was, I wanted to explore problems and areas where we didn't have answers. In fact, where we didn't even know the right questions to ask.
