The right way to build a company is to experiment in lots of small ways, so that you have plenty of room to make mistakes and change strategies.

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.

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

I'm not a political person. I'm a techie nerd, and I enjoy the techie part. I mean, all my life, I've loved great technology.

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.

As for companies invested in the space - I think its important to distinguish between a good investment and a material climate change technology - you can have the first without the second, even in the "clean tech" space.

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.
