It is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive.

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.

I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems.

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.

People should pursue what they're passionate about. That will make them happier than pretty much anything else.
