I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I've got kids and responsibilities, so I can't be my own test pilot. That wouldn't be a good idea. But I definitely want to fly as soon as it's a sensible thing to do.

There's a tremendous bias against taking risks. Everyone is trying to optimize their ass-covering.

Even if producing CO2 was good for the environment, given that we're going to run out of hydrocarbons, we need to find some sustainable means of operating.

The fuel cell is just a fundamentally inferior way of delivering electrical energy to an electric motor than batteries.

Engineering is the closest thing to magic that exists in the world.

A battery by definition is a collection of cells. So the cell is a little can of chemicals. And the challenge is taking a very high-energy cell, and a large number of them, and combining them safely into a large battery.

I was born in Africa. I came to California because it's really where new technologies can be brought to fruition, and I don't see a viable competitor.
