The most interesting talk at Space Access was a fill-in that was not blogged by Rand, but was by Clark Lindsey:

a CEV concept [was presented] that Boeing is investigating that involves commercial delivery of fuel to orbiting depots. This so-called “dry launch” approach would mean that vehicles for in-space and lunar transport could be launched without fuel and so, being lighter, they would not need new heavy lifters. This would open a great opportunity for the new launch companies to provide fuel to the depots.

It involves an alternative concept (see page 32) from Boeing. The idea is to launch the lunar transfer vehicle dry and provide commercial propellant delivery. This could result in thousands of metric tons of fuel needing to be delivered to LEO. This might bootstrap the commercial launch industry. There are also opportunities for “the last mile” because some launcher companies will not want to have to figure out how to dock with a fuel depot.

1000 metric tons of fuel would be a cool $3 billion unless someone can undercut Elon Musk. 9000 metric tons through 2030 would be $27 billion at current prices, but would likely spur a tech drive and a bidding war to compete prices down to $1000/kg or less.
