Big breakthroughs happen when what is suddenly possible meets what is desperately needed

Our president's latest energy initiative was to go to Saudi Arabia and beg King Abdullah to give us a little relief on gasoline prices. I guess there was some justice in that. When you, the president, after 9/11, tell the country to go shopping instead of buckling down to break our addiction to oil, it ends with you, the president, shopping the world for discount gasoline.

In China today, Bill Gates is Britney Spears. In America today, Britney Spears is Britney Spears-and that is our problem.

I am always a little skeptical on the water thing because I have been hearing that for 30 years, but one year it's going to be true. With the rising populations, Yemen could be the first country in the world, or Sana'a the first major city in the world, to run out of water, that's from Yemeni hydrological engineers and the United Nations. Sooner or later, all of these people, from 7 to 9 billion, all of them want to live like America, will be consuming so much more water that some of the societies will hit a wall without more sustainable environmental practices.

Hillary Clinton has decided to line up with John McCain in pushing to suspend the federal excise tax on gasoline, 18.4 cents a gallon, for this summer's travel season. This is not an energy policy. This is money laundering: we borrow money from China and ship it to Saudi Arabia and take a little cut for ourselves as it goes through our gas tanks. What a way to build our country.

We are led by lawyers who do not understand either technology or balance sheets.

So what am I? I guess I would call myself a sober optimist...If you are not sober about the scale of the challenge, then you are not paying attention. But if you are not an optimist, you have no chance of generating the kind of mass movement needed to achieve the needed scale.
