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.

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

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

Communication always changes society, and society was always organized around communication channels. Two hundred years ago it was mostly rivers. It was sea-lanes and mountain passes. The Internet is another form of communication and commerce. And society organizes around the channels.

Certain food-based biofuels like biodiesel have always been a bad idea. Others like corn ethanol have served a useful purpose and essentially are obsoleting themselves.

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.

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.
