![]() ![]() This is something I've never experienced because I've simply never tried a small drill on an asteroid. Reading the thread again makes it look like we were talking at cross purposes. So the bug that was talking about must have been what you said - losing mass under time warp with the small drill - and not what I misunderstood it to mean. OK so I was premature in screaming earlier (my 1.2 career save has taken second place to playing with a bunch of other things, so I'm far from mining asteroids yet). That is, to fill a 300-unit tank of ore to its 3-ton capacity, the asteroid loses 6 tons of mass, but only under time-warp. The loss of asteroid mass is double what it should be, when using any speed speed of physical or on-rails time-warp. But, there is a bug with the small drill under time warp. Even with simultaneous conversion to liquid fuel using the big ISRU, total mass is conserved. The decrease in asteroid mass matches the increase in mass of ore in the tank (10 kg/ore). Mass is conserved by the small drill (as opposed to the small ISRU) when it is at operating temperature. The small drill at xx% fractional 'thermal efficiency' removes mass from the asteroid as quickly as it would at 100% 'thermal efficiency' but only stores xx% of that mass as ore, losing the rest to space.Īs Plusck says, closing all ore tanks while the drills warm up will avoid this loss.Īmusingly, having any on-board engineer go on EVA during the warm-up period reduces the rate of mass extraction during this period and thus the loss. ![]() Mass is conserved by the small drill (as opposed to the small ISRU) when it is at operating temperature. Half the mass taken from asteroid appears as mass of ore. I do get 0.05 ore/sec from an asteroid with the small drill (0.85/sec with a 3-star engineer, 0.05 when he goes on EVA) I guess I will put some radiators on my asteroid miner Originally I thought that efficiency only mattered for the speed of extraction. Thank you, I didn't realize having the drill at 100% efficiency had an impact on mass loss. Mass loss (meaning ore loss) using either drill at less than 100% efficiency. Mass loss (meaning ore loss) using the small drill at 100% efficiency (which i suspect will be 0.20/sec x 5kg = 1kg/sec) Ore output from an asteroid, for both the large and small drills (definitely 0.25/sec for the large, probably 0.05/sec for the small) ![]() So yes, there are three things to write into the wiki: I'd guess that the small drills produce a fifth of that, chucking the rest of the mass away. It will not lose mass if the drills are at 100% efficiency, but will lose mass if they aren't. So it's definitely 1/5th the production of the larger drills.Īnd a large drill (with no engineer) will produce 0.25 ore/sec on an asteroid. The numbers given in the wiki for production on a CB are exact (I checked this for a thread recently - " ISRU is less more" - with a ton of small drills on a good patch on Minmus). Good idea - the wiki entries don't give all the relevant facts. I was thinking of verifying the exact number, and then writing it into the wiki. There should definitely be something about that added somewhere. ![]()
