Every big problem is a big opportunity.

Everybody else is afraid to fail. I do not really care because when I fail, I try something new.

The only way you multiply resources is with technology. To really affect poverty, energy, health, education, or anything else - there is no other way.

If I collected all the diamonds in the world, I'd have no 'income' but I'd have a lot of 'assets'. Would my company be worth nothing because I have no income? A lot of Net companies are collecting assets. They have to be measured with a new set of metrics.

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.
