> A 100MW datacenter will emit 1.5 million tons of CO2 over a 5 year lifetime (given average USA energy sources). In contrast, 10 Starship launches (~1,000 tons to orbit) will emit no more than 40,000 tons of CO2.

How did you come to 10 launches / 1000 tons as what it takes to launch a 100MW data centre in space?
