Note that when crafting Mobius Fuel, or for a matter of fact any type of EE fuel such as Aeternalis Fuel and Alchemical Fuel, you may put the Philosopher's Stone anywhere in the Crafting Table and place the 4 amounts of fuel using in any other 4 slots in the crafting table. The philosopher's stone does not need to be charged. Its total EMC value is 2048, making it able to make gold.
Despite common opinion, Mobius Fuel is probably not named for a Latin word. Rather, it is likely named after August Ferdinand Mobius, a German mathematician known for his "Mobius strip," a strip of material twisted and wrapped into a circle, but with only one side. This mirrors the naming of the Klein Star after Felix Klein, another German mathematician known for a topological curiosity, the Klein bottle. It appears that the idea is that these materials store energy with a high density using exotic topologies.
