You're right about the energy, I changed that back after finding you can't power life support from Solar Cells. But I found it too easy not needing any life support at all for Mun trips and I wanted trips to Jool etc to FEEL like a big expedition, maybe even have a reason to want to fill up on Oxygen in Laythe's atmosphere. Just trying to challenge myself in the game maybe to balance that I added the bigger rockets from the popular packs, and modded engines a bit to simulate near-future sci-fi - I mean, the "Ariane 5 Clone" craft I downloaded FAILED to make orbit, and I'm pretty sure the real one works just fine, so I use better rockets but I make life support and caring for crew comfort more of a challenge. I hope this gets updated and becomes able to prevent cheating ie/kill kerbals in non-active ships. Accuracy/Apollo data? I'm not sure. Scrubbers don't use much power, but do use up some chemical instead. Recovering the Oxygen from CO2 would take power, its not just fans. But.. yeah.. in KSP you can get to the Mun in hours not days, so you're right, but for gameplay/roleplay I think my way fits (when I changed power back to normal) and gameplay is what matters to me. Thanks, mainly I want Yongedevil to see how awesome he is. Everybody is making big rockets, theres no shortage of those. But nobody else has done a real life support mod which makes KSP a real Sim not just a "robots in rockets" game. Thanks Corum.
