NOTE:

CT allowed "void jumps" into 'empty' hexes as was described in the LBB adventure 'Twilight's Peak', occurring during the 3rd Frontier War.

 Canonically, one can scoop unrefined fuel
 from the atmosphere of a gas
 giant, or dip it from the oceans of an
 Earth-like world, and then
 refine it for use in the jump drive and
 power plant. This suggests
 that the canonical refiners can break
 down Damn Near Anything to get
 the hydrogen out, and then compress and
 cool the hydrogen into stored
 refined fuel.

 OK. I'm with that. I'll take a handwave
 on the actual tech.

 I'm willing to accept that a facility
 that uses fuel will do so faster
 than reasonable refining capacity can
 provide it - that is, the
 refiner can't feed the plant or j-drive
 directly; you need the total
 volume of refined fuel available when
 you hit the 'go' button.

 TNE allowed for "empty hex" jumps, to
 'Calibration Points' -
 essentially, deep-space stations. I
 believe that the assumption was
 that there was an icy body to provide
 fuel there, large enough that
 there was no need to discuss how they
 were supplied.

 Assume now that a deep-space station
 _does_ need to have fuel
 "trucked" in. The station has
 sufficient tankage and sufficient
 refining capacity to meet its needs as
 a fueling station, plus it can
 keep itself supplied with respect to
 power plant needs. What's of
 interest now is how to most efficiently
 truck the fuel in.

 A little browsing of Wikipedia says
 that refined fuel - Liquid
 Hydrogen, H2(l), has a density of
 70kg/m3 - or, by definition of a
 Traveller dton (displacement ton), 1
 tonne per dton.

 Question: (Please show your work!) What
 substances can be transported
 with an "effective refined fuel
 density" (ERFD) that's higher than
 H2(l), and what substance has the
 highest ERFD? Also note if the
 substance in question requires any
 special handling (i.e., deviations
 from STP) to achieve the stated ERFD.

 (It's understood that by definition,
 anything with a higher EFRD than
 H2(l) is "unrefined" fuel. That's OK;
 remember, it's being refined
 on-site at the deep-space station.)
