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.

The future of humanity is going to bifurcate in two directions: Either it's going to become multiplanetary, or it's going to remain confined to one planet and eventually there's going to be an extinction event.

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

My background educationally is physics and economics, and I grew up in sort of an engineering environment - my father is an electromechanical engineer. And so there were lots of engineery things around me.

The tough thing is figuring out what questions to ask, but […] once you do that, the rest is really easy.
