Design is inherently optimistic. That is its power.

I am very focused on large-scale deployments of renewable power and how we're going to get this done. Imagine our military bases covered with solar thermal collectors that could generate steam and electricity.

Nuclear power can never be made inherently safe. There is always a danger. But there's also always a danger with any form of electricity generation. The goal is to have that risk managed to an acceptably low level.

Not everything needs to be recycled.

Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!

I'm rather pleased, to put it mildly,
