Background

I think there's a strong possibility that we're at a turning point in history--a complete revolution in human affairs--the discovery of totally new energy sources. Many people are skeptical of this, but I think we may be going through the four stages involved in any revolutionary development:

1. It’s nonsense! Don’t waste my time.
2. Oh, it’s interesting, but not important.
3. I always said it was a good idea!
4. I thought of it first.

--Arthur C. Clarke
