+# Chrome Production Calculations
+
+**498 total chrome needed**
+
+## Chrome Ingots from Chrome Dust
+
+1 chrome dust in an IBF takes 40 seconds. For 498 chrome that would take ~5.5 hours. 4 IBF (one circle around a casing) takes 1:23h.
+
+Power consumption is 128EU/t per IBF.
+
+## Chrome Dust from Ruby Dust
+
+9 ruby dust make 1 chrome dust in an electrolyzer in 25 seconds. For 498 chrome dust, 4482 ruby dust are necessary. In one electrolyzer, this would take ~3.5h. 4 electrolyzers need 51 minutes.
+
+Power consumption is 50EU/t per electrolyzer.
+
+## Ruby Dust from Redstone Dust
+
+10 redstone dust make 1 ruby dust in a centrifuge in 350 seconds. A stack of centrifuges produces 1 ruby dust every 5.47s or 0.183 ruby dust per second. For 4482 ruby dust, a stack of centrifuges needs 6:48h. Two stacks need 3:24h, 3 stacks 2:16h, 4 stacks 1:42h.
+
+Note that extra rubies will be found by the mining turtles/quarry.
+
+Each stack of centrifuges consumes 1.8 redstone per second or 110 redstone per minute. For the entire 498 chrome, 44.8k redstone are necessary.
+
+Power consumption is 320EU/t per stack of centrifuges.
+
+## Suggestion
+
+- 4 IBFs on chrome -> 1:23h, 512EU/t
+- 4 electrolyzers -> 0:51h, 200EU/t
+- 3 stacks of redstone centrifuges -> 2:16h, 1280EU/t
+
+In 1:23h, the centrifuges would produce 2732 ruby dust, so quarries would need to supplement 1750.
+
+Total power: ~2000EU/t, needs about 10 boilers
