Also, in this PBS interview, he discusses the potential for a boom that extends beyond what people call clean tech or green tech:
they refer to interesting little markets like hybrids and batteries and solar cells and wind farms and corn ethanol and biodiesel, but that's not where the real opportunity is.
Those are nice markets, nice investments, people make money at it, but the real big opportunities are changing the infrastructure of society. We are talking about things like the $200 billion engines market for automobiles and trucks, things like lighting, billions of dollars spent on lighting. We can completely change that. Cement. Huge multi-hundred billion dollar market that needs to change. Glass. Then there's replacing all of the oil in the world. Hundreds of billions if not trillions of dollars worth of fuel that needs to be replaced. And there's gasoline, there's diesel, there's jet
And then there's electric power generation. Not the kind you get from a PV cell, that's a good market, but the stuff you can actually store and ship and the utilities meet it at the prices at which utilities can buy power.
