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

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.

In the next 10 years, data science and software will do more for medicine than all of the biological sciences together.

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

Every big problem is a big opportunity.

There's no doubt in my mind over the next 25 years how we drive, how we build our houses, how we fly, how we build our buildings, will all change.
