This is a really fun thread, enjoyed reading it Cary and Bob.
There was some other posts going on about how the 'linear intermix shaft' could work and if Probert had it right the first time / the idea was better than the TNG idea.
I had thought about this:
-TOS had a pretty large reactor, used little Dilithium, but depleted it at very high rates when at high rates of speed. Dilithium is used to mediate the reaction and make use of the energy into usable radiation.
-Intermix Shaft/Energizers - used LOTS of Dilithium but it depleted very slowly under all load levels. There's an initial reaction at the bottom of the shaft and more and more reactants are fed up, with dilithium in each transfer segment as well as being released as particles in the shaft to mediate and create the right kind of electrical charge. Some of the segments siphon off into power converting energizers. The whole thing was very complicated and very hard to manufacture.
--TNG (or...late movie) - reactor we're used to. Uses little crystal and it decays evenly, which is fine, because it can be recrystalized anyway. Reaction to dilithium mediation which causes the plasma to energize.
But I just imagine the MASS of these things, especially warp coils, to be very prohibitive to lug around. Maybe that's why the Constellation Class had 4 besides just mass of the ship - maybe that's as close as Starfleet got to unsupported endurance ships.
I think the idea of several small reactors linked together would be a cool direction to go if we ever get a future Trek.
