To be fair, it’s not entirely his fault: he took NASA’s early-1970s estimates of Space Shuttle flight rates as gospel—one flight per week, costs around $1M/ton delivered into orbit—back when they were selling it as a “space truck”. At which point, hauling 50,000 tons of hardware and 10,000 workers into orbit to build a gigantic factory town churning out gigawatt range solar power stations using materials mined from the lunar regolith and positioned where they could transmit microwave power beams down to Earth 24×7 sounded like it should cost about as much as the 350-odd tons and 6 astronaut crew of the ISS. And as a solution to the 1974 oil shock, it seemed like a good idea. If we ever do get space trucks like that, it might be time to dust off those concept drawings and go for it.
