He made one comment, a decade ago, well before he started talking about $35/kg to orbit with Starship.

In response to his famous question "what's the conversion rate," the answer is about 50%, according to the book The Case for Space Solar Power. That's not bad considering a panel in geostationary collects five times as much energy in 24 hours as a panel on Earth.
