And they don't require external power, unlike in Classic Traveller from HG onwards (and thus the LBB 1-3 '81 versions). So the original LBB ships didn't require external power for the jump drive. From HG (including the original 1979 version) onwards you needed power from a power plant. Then MT says you don't need power, which TNE keeps (along with MT's changed fuel requirements). TNE/FF&S (perhaps sensibly) doesn't discuss what a jump drive is (aside from mentioning that it's 35% capacitors by volume), just what it does and what it requires. In both cases, being able to use the jump drive's capacitors to store energy from a black globe implies that you should be able to charge them from your main power plant, and logically that should save you fuel, unless almost all of it is used for what TNE calls 'displacement mass'. Gah. What a mess. -- Rupert Boleyn <xxxxxx@gmail.com>
