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

I've probably failed more often than anybody else in Silicon Valley. Those don't matter. I don't remember the failures. You remember the big successes.

Not thinking it's possible is a failure of imagination.

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

Every big problem is a big opportunity.

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

I do not know what got me interested in technology. What was very clear to me very early on was that I was not interested in religion and that naturally increased my curiosity about science and technology, and I fundamentally believe the two are conflicting.
