What most people know but don't realize they know is that the world is almost entirely solar-powered already. If the sun wasn't there, we'd be a frozen ice ball at three degrees Kelvin, and the sun powers the entire system of precipitation. The whole ecosystem is solar-powered.

I'm personally a moderate and a registered independent, so I'm not strongly Democratic or strongly Republican.

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.

You need to live in a dome initially but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on. ... So it's a fixer-upper of a planet.

I'm extremely confident that solar will be at least a plurality of power, and most likely a majority... in less than 20 years.

I don't think it's a good idea to plan to sell a company.

I think you should always be seeking negative feedback.
