Glowstone Flux (gF) would be moved with molten glowstone. Molten Glowstone is made in a series of Melters, much like the heat generators of today. These would include a solid- and liquid-fueled melter, an electric-based one, a reactor and a radioisotope thermoelectric melter (RTM). Machinery powered by this would output Glowstone Dust so it is a closed loop, and would include the Blast Furnace, the Glowstone Generator (generates RF) and the Fermenter. Figured that since EU is being replaced, might as well make Heat more fitting.
