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

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

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.

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

Seeking an acquisition from the start is more than just bad advice for an entrepreneur. For the entrepreneur it leads to short term tactical decisions rather than company-building decisions and in my view often reduces the probability of success.

In my view, it’s irreverence, foolish confidence and naivety combined with persistence, open mindedness and a continual ability to learn that created Facebook, Google, Yahoo, eBay, Microsoft, Apple, Juniper, AOL, Sun Microsystems and others.

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.
