  1. I think you can store one sample from each type. So it's best to transmit them as long as you get anything, and bring the other later. This way you don't need to revisit.
  2. If so, I still think its dumb... the transmission function was already nearly useless... now its even more of simple a 3.5 ton weight to lug around to reset goo and mat bays. Actually lab is great. Think about landing on each biome of a different planet. The lab is supposed to be left in orbit... Transmission is also useful, you transmit, then bring a sample home. You get all the science this way, so you needn't revisit said biome. Think about visiting each biome of Jool's moons... It even helps for the local moons. Honestly I don't remember case I didn't use lab+lander to clear up all the biomes on Minmus and the Mun.
  3. Current water splitters can store around 40% of the energy used. The problem of course is getting enough "green" energy to produce the hydrogen. If fossil energy is used, a reformer is actually cleaner than splitter. On a side note, levelized cost of onshore wind (e.g including all costs including the power-plant), is around the same as gas. This is when it works at 30% of capacity. Technology has progressed quite a lot in last decade, unlike political will and investment logic.
  4. Ha ha, you know the hydro in hydrolox comes from methane reformers, which produce CO2. So it's not that much cleaner as one might think.
  5. Planes make whole lot of sense to low orbit. After that just pick the payload with a nuke powered orbital tug.
  6. Ramarren and this is exactly what I'm asking - does it actually work. I did in fact try with different generators, NF, USI, interstellar, B9 and got various results. I also tried it with different amount of batteries. Then the other puzzlement I had was the whole EC to J conversion. If the splitter really assumes 1J=1EC, the ridiculously low amount of split water is not a surprise.
  7. Right, so even worse according to your math. And BTW I also made another error. I asked if 1EC is 1 Watt, when I should have been asking, if 1EC is 1J. Power has no time element. W = V*A. A 2MW reactor provides 2MW of power. Time has no bearing on this. The work of said reactor would be both 2MW*s or 2MJ, or 2MW*h. Note this is not MW/s but it's power multiplied by time. So if 1EC=1kJ, 1EC/s will be 1kJ/s, or that is 1kW. And yes 2000EC/s will be 2MJ/s or 2MW. However I don't believe 1 EC = 1KJ. I think it's more close to 100J than 1000J. Thing is depends on which part you look (talking about stock) they seem to be rather arbitrary. For example a lamp uses 0.04EC/s. So if we go with 1J=1EC that would make said lamp 0.04W. Yes the RTGs in KSP are ridiculous. They provide same power as the nontracking panels. In reality, a cheap trailer solar panel will easily provide 60-100Watts. So if 1EC/s = 1W = 1J/s, a typical solar panel should provide 60-100EC/s. Like you said a battery would have 1.41Wh, or 5076J, so if 1EC = 1J, batteries should be 5000EC or more... And yes water splitting is not particularly efficient in real life. A water splitter they are building in Germany, requires around 40MW of power (yes it's big installation), and should be able to produce roughly 2 tons of hydrogen a day, by splitting around 36 tons of water...
  8. I'm not talking about RTGs. I'm talking about a fission reactor, which at least in game says it produces 3000kW thermal power. As unrealistic as it might sound cooling a 3MW reactor in space, or be that small, I'm not sure if 3kw fission reactor is even possible. Edit, moreover, an AAA batery has around 90 Watt seconds, so if it 1EC is 0.1W their batteries seem to be really bad. Also if you have noticed, the lamps use only 2.4EC/minute, or 0.04 EC/s. So yeah, I'd like to see any 0.004W lamps.
  9. Deadpan, I'm not criticizing, I'm trying to figure out if the mod actually works as intended. I just find it pretty amazing that with the energy produced by nuclear reactor, can't seem to split more than 2l of water a day. I guess it just depends on what we think 1 EC is. What does this mod assume? 1W? I guess probably the problem is that nuke reactors in ksp are ridiculously underpowered, 3KW nuclear reactors seem a bit feeble.
  10. Perhaps I'm just doing something wrong then? I don't know about realism, but wondering how on earth they fill those big storage tanks with LH? I get that a whole factory is working on it, but still the electricity usage seems rather ridiculous for the amount of splitting which happens. EDIT: I'm aware that probably most is made from natural gas rather than water
  11. Ok, I really don't understand how to use this. Or is really this useless? I got a generator generating 3000EC/s. The splitter says EC depleted. In 41 earth days I managed to split only 80 liters of water, and produce 83 units of liquid hydrogen. Doesn't seem right to me...
  12. Hi. Is there a way to clean the state of the "story missions". I started a new game, and first story mission I seem to be getting is luna II. Which was the last mission I got in my previous game.
  13. Anyway the point is, that "chute failed due excessive heat" can also be understood as the actual case failed. Especially in case of radial chutes. So assuming you are coasting down at 400 m/s and the ship temperature is around 150 degrees, saying reason was the temperature is not exactly pointing to the exact error you made deploying your chute. (though it does show which mod pwnd you) Honestly I still claim dynamic pressure is your general problem with chutes, especially at lower altitudes, even though temperature does in fact reduces the material strength. Still the pressure would rip the chute apart before it has chance to catch on fire. No problem with lead bullets melting when flying at 1000m/s. Kevlar/nomex will 'burn up" between 350-500 degrees (people love to debate which is better and what's a good test). So if the drogue chute is failing when the lead part of your vehicle is at 150 degrees, it either was not the heat, or the thermometer is broken. On the bright side, those test chute missions, seem to finally serve a purpose.
  14. Actually it partly is. The message telling you a chute failed due heat. Now I'm not expert but I think there is no chute which will ever be able to withstand the dynamic pressure required to compress the air enough to produce any heat... So it in fact it fails due to aerodynamic stress, and not heat. Now the interesting part, is that failure would (maybe fixed by now) actually happen the moment you staged your chutes, regardless whether or not they actually deploy. So if you have a real chute set to predeploy at 2000m, and you stage at 15000m (thus just arming it), and you'll be wondering why, and when your chutes failed to heat... The size of Kirbin of course matters as well, as far as stopping distance and sweet spot is concerned. The point was that you can easily end up at 5km altitude moving at 400m/s. G force and heat would be rare problems. It's a bit messed up, compared with earth. While orbital speed is around 4 times lower, and atmosphere extends 7 times higher, orbit is 10 times smaller. Anyway, once you know that is not in fact heat, deploying your chutes when safe is not that problematic.
  15. Well it's always complicated of what organisms produce. Been long time since I thought of organic chemistry, so I hope I still remember these correctly. In simplified terms... There is a good amount of 'water' trapped in the food. Even dry carbohydrates have the "hydrate part". If you look at most sugars, CnH2nOn. So by mass H+O is 60%, they are also in perfect H20 ratio. Now of course you'll need oxygen for the carbon, so by mass the ratio between incoming sugar and oxygen (mix) is roughly 48/52% and the resulting H20 to C02 is 29/71%. All the oxygen will end up in CO2. Things with fats are much more complicated. They contain mostly C and H, with very little oxygen, so generally "chain of CH2". In any case, intake oxygen will be used to produce both C02 and H2O. So if we consider just the CH2 parts, you get 22%(CH2)/78%(O) resulting in 29%(H20)/71%(C02). Here 33% of the oxygen used will actually end up in water. Proteins are just too complicated for me (though they are mainly CH + other stuff with less oxygen). They are more interesting for their nitrogen, and form. Interestingly the output is the same in both cases, however second case uses much more oxygen. The first case will release the hydrate part as water, second will produce it. In both cases you have extra water entering the system, even if you assume completely dry food. Metabolism will in fact produce water. Obviously second case will require oxygen to fix the hydrogen as well, so you'll end up with less CO2 for the same amount of oxygen. So realistically, if you are not dumping/splitting water you will in fact end up with more water. This is pretty important fact for any LS. This is one of the reasons why a water splitter (IRL) would make sense. Why would you bring water splitter and water, instead of just oxygen (other than tank tech)? Reasons are two. 1. You need a way to release the oxygen fixed in the metabolism (case 2). You also get extra water coming in with food, or hydrates in it. 2. Resulting hydrogen can be used in sabatier reaction, thus reclaiming oxygen fixed in CO2, (in form of water which can be split again). A RL carbon extractor (splitter+sabatier) would generally suffer from hydrogen shortage. You need 4 waters to break one C02, and get 2 water back. Another interesting thing is that a lot of the water can be easily reclaimed as condensate. For some reason when we talk about water recycling, most people seem tho think about urine, while a lot of water is actually reclaimed as humidity control, and is much easier to recycle.
  16. How about you stop adding your insight to every thread. There are actually mods which are usable even if not recompiled, so no harm done in asking if someone knows whether it works or not.
  17. Well used to be 1 unit 1 day, but people really wanted liters. Now using MFT is pretty 'interesting'
  18. Even extending kickstand keeps the hatch blocked unfortunately. Maybe just landed on the wrong place.
  19. Are the life pods supposed to have no food? foodAmount = 0.0001? Also they seem to always end the hatch down, and haven't found a way to turn them over.
  20. On the other hand, bigger pods would be nice, though I guess one can always use a cluster
  21. I don't know what you are looking at. its a 1.25 sphere, or around the size of 1 person lander can
  22. I seem to have a problem with the derp propulsion module, it plays the rcs animation all the time (including the VAB), any clue on that?
