There are parts of the country in America, in the Midwest, where wind is a big resource, and we should absolutely use it. But to try and apply it nationally doesn't make sense. There are technologies that will work that are appropriate to certain regions.

We don't need a fuel that's cleaner, we need a fuel that happens to be cleaner, but is half the price of oil.

I believe cellulosic fuels, biofuels made from nonfood crops are the only solution that will make a difference.

The world is hung up on food-based biofuels. Not only are they the wrong thing, they're the uneconomic thing.

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.

Future is not extrapolation of past

Electric cars are coal-powered cars. Their carbon emissions can be worse than gasoline-powered cars.
