"Will Pearson: Shut up and multiply. 150K/day adds up to about 3B after 60 years, which is a conservatively high estimate for how long we need. Heads have a volume of a few liters, call it 3.33 for convenience, so that's 10M cubic meters. Cooling involves massive economies of scale, as only surfaces matter. All we are talking about is, assuming a hemispherical facility, 168 meters of radius and 267,200 square meters of surface area. Not a lot to insulate. One small power plant could easily power the maintenance of such a facility at liquid nitrogen te... (read more)
