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

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.

Will biofuel usage require land? Absolutely, but we think the ability to use winter cover crops, degraded land, as well as using sources such as organic waste, sewage, and forest waste means that actual land usage will be limited. Just these sources can replace most of our imported oil by 2030 without touching new land.

For electric power generation, we are very optimistic about solar-thermal technology, and we’re intrigued by the potential of enhanced geothermal energy to replace coal-based power generation. Traditional carbon capture and sequestration-based coal power generation is somewhat unlikely to be competitive.

No one will pay you to solve a non-problem.

The first rule of venture capitalism is hands-on experience. You have to get your hands dirty.

I'm a fiscal hawk. I vote against all taxes, but I do believe the environment, and climate change, is a bigger issue than fiscal deficits are as a risk to the nation.
