I've actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don't mean hybrid, I mean fully electric.

I hate writing about personal stuff. I don't have a Facebook page. I don't use my Twitter account. I am familiar with both, but I don't use them.

Silicon Valley has evolved a critical mass of engineers and venture capitalists and all the support structure - the law firms, the real estate, all that - that are all actually geared toward being accepting of startups.

I think life on Earth must be about more than just solving problems... It's got to be something inspiring, even if it is vicarious.

There's a real opportunity to have a vertical takeoff and landing electric supersonic jet.

I've always wanted to be part of something that would radically change the world. . . . People forget the power of inspiration. All of humanity went to the moon with the Apollo missions. The issue was cost. There was no chance to build a base and create frequent flights. That's the problem I would like to solve.

You need to be in the position where it is the cost of the fuel that actually matters and not the cost of building the rocket in the first place.
