He says that at a minimum, megatons of equipment and other resources have to be put in orbit <em>every year</em>. For reference, a <a href="https://en.wikipedia.org/wiki/Saturn_V">Saturn V</a> (the launch vehicle used to send humans to the moon), can take a payload of around 140 tons to <a href="https://en.wikipedia.org/wiki/Low_Earth_orbit">Low Earth Orbit</a>. A launch of Saturn V costs $1.23 billion (in 2019 value). To reach the goal of a megaton per year there would have to be more than 7000 launches per year, or 20 launches per day! That would cost $8.8 trillion(!). But of course, technology has come a long way since 1969.</p>
