FAQ
What is the best generator in ICARUS?
By output, the Nuclear Reactor (100 kW, Dangerous Horizons). For steady fuel-burning power, the Biofuel Generator makes 5 kW on 2.4 L/h of biofuel: 75 MJ per Biofuel Can, 2.7× the Portable Biofuel Generator's 27.5 MJ. Solar Panels need no fuel and give 6 kW nominal, which varies in-game.
How long does a Biofuel Can last in a Biofuel Generator?
4h 10m at full output (2.4 L/h), making 75 MJ. The wiki gives the same runtime.
How much power does the Electric Furnace use?
2.5 kW (2,500 units/s) while it runs, as stated on the ICARUS wiki (the game data's generic processor flow has no rate). One Biofuel Generator runs 2 of them.
How many generators do I need?
Add up the draw of everything running at once and divide by the generator's output, rounding up: 12.5 kW needs 3 × Biofuel Generator (5 kW each). The budget builder above does it for every generator type.
How long does a battery rack last?
A Basic Battery Rack stores 1 MJ (1,000,000 units), so it runs one Electric Furnace (2.5 kW) for 6m 40s. Divide the stored energy by your total draw (J ÷ W = seconds).
How much power does a Solar Panel make?
6 kW (6,000 units/s) nominal in the data. Real output varies in-game with sunlight and weather, so treat it as a ceiling.
How we compute this
Generator fuel use and runtime
mL/s = GenerationRate ÷ GenerationRatio; runtime = container mL ÷ mL/s; energy = mL × ratioFrom each generator's D_Generator row and the container's D_Fillable size. The Biofuel Generator: 5,000 units/s (5 kW) ÷ 7,500 units per mL = 0.667 mL/s, so 10 L lasts 4h 10m and makes 75,000,000 units (75 MJ). One game unit is one joule, so units/s are watts. Fuel use assumes full output. Solar, wind and water wheels show their nominal rate.- Source: ICARUS wiki: Biofuel Generator —

Device power draw
draw (W = game units/s) = D_Energy flow rate, else a cited override, else computed in-gameMost electric benches use a generic processor flow with rate 0 in the data, so their draw comes from a cited override (the wiki states it) or stays computed in-game. Pumps draw output ÷ ratio from their D_Generator row.- Source: ICARUS wiki: Electric Furnace —
