Dyson Sphere Program has several ways of generating power. From the [[Wind Turbine|wind turbine]] you start with, to [[Mini Fusion Power Station|fusion generators]], [[Artificial Star|artificial stars]] and of course the Dyson Sphere itself. Some of these generators and your mech, Icarus, run on one or more different fuels.

'''Fuel chamber gen.''' marks how efficient your mech's Fuel Chamber is at converting the fuel. This only changes how fast energy is recharged, not how much total energy is produced. Note that [[Coal]] with 0% is the only fuel that matches your [[Energy Circuit (Upgrade)|Energy Circuit]] upgrade level. Both positive and negative percentages are relative to this. For instance, both a [[Hydrogen Fuel Rod]] and the 5 [[Hydrogen]] it requires to produce contain a total of 40MJ (before patch '''0.6.17.5972, [[Hydrogen Fuel Rod]]''' now contains 54MJ), but the fuel rod has a Fuel chamber gen. of +200% instead of the +100% of regular hydrogen, meaning you will use the fuel rod 50% faster (300% total charge rate compared to 200%) than the regular hydrogen and therefore recharge energy 50% faster.
