Solar and wind are now cheaper in many places than some fossil fuels and within the next two years, three, four, five years at the most. What the exponential curve does isn't going to go away. It is totally over for fossil fuels and nuclear. Nuclear's actually gone out.

James Watt patented his steam engine on the eve of the American Revolution, consummating a relationship between coal and the new Promethean spirit of the age, and humanity made its first tentative steps into an industrial way of life that would, over the next two centuries, forever change the world.

Companies that actually survive and flourish are going to change their business model from production to aggregating the networks and the network services and solutions. If you're a construction company or an IT company or a logistics company or an information data operation, to the extent that you can find ways to help build the commons, you can get some commercial value in that.

Wikipedia is an amazing construct. It's a commons that works. I don't know how Jimmy Wales came up with it. I'm sure all of us would have said, "This is the stupidest thing we've ever heard of. That'll never work in a million years."

It may be that everything the life science companies are telling us will turn out to be right, and there's no problem here whatsoever. That defies logic.

We were making the first step out of the age of chemistry and physics, and into the age of biology.

The hydrogen economy will make possible a vast redistribution of power, with far-reaching consequences for society. Today's centralized, top-down flow of energy, controlled by global oil companies and utilities, could become obsolete.
