For my part, I will never give up, and I mean never.

To make an embarrassing admission, I like video games. That's what got me into software engineering when I was a kid. I wanted to make money so I could buy a better computer to play better video games. Nothing like saving the world.

You could power the entire United States with about 150 to 200 square kilometers of solar panels, the entire United States. Take a corner of Utah... there's not much going on there, I've been there. There's not even radio stations.

My motivation for all my companies has been to be involved in something that I thought would have a significant impact on the world.

People will buy the car just because it's a great car. We want them to think it's excellent value for money and then, oh yeah, it happens to be electric.

Land on Mars, a round-trip ticket - half a million dollars. It can be done.

My mentality is that of a samurai. I would rather commit seppuku than fail.
