[10:59:50] TheKosmonaut: btw what should I do if I want to use a grounded device like seven meters from the only gnd screw terminal in my apartment [11:00:55] why do we still use plugs and outlets designed in a time where nobody gave a damn about electrocuting you and burning your house down [11:16:30] well tbh it's kinda usual to have outlets without grounding wire attached [11:16:50] in what world do people still have outlets without ground? [11:17:13] i don't think i have even seen those in my entire life [11:56:06] A lot of old houses (pre 1970) do [11:58:00] that's an interesting definition of old house [11:58:12] my house was built in 1760something, what does that make it :p [12:05:54] VanDisaster, an old hovel? :D [12:12:20] bit older than usa [12:13:15] I work in a building that they had to add electricity to after it was built (by decades) and even that still has many non-grounded outlets (which are getting replaced slowly as we use them for things beyond simple lighting) [12:21:35] VanDisaster: where do you live [12:21:48] southwest UK [12:21:53] ah [12:22:05] oldest building in the city i live in is from 1755 or so [12:22:58] some of the farmhouses around here are a few lifetimes older than this building [12:24:06] the oldest building in my city is ~1130 [12:28:36] the local city has a few roman walls left, the buildings aren't *quite* that old :p [12:37:46] https://pr0gramm.com/new/2802467 nice anti-lag sound [12:38:58] people in north america didn't do a lot building before the whites invaded did they? [12:40:05] https://en.wikipedia.org/wiki/Church_of_St._Lawrence,_Vantaa guess this is the oldest building within like 20km from where i live [12:45:54] https://en.wikipedia.org/wiki/Exeter the nearest city [12:55:43] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [13:28:43] I don't actually know when my place was built but I'd assume 5-10 years ago [13:29:22] the building neither seems to be aging nor built to last very long [13:30:10] hehe [13:31:40] like heck, the windows stick outwards to give an illusion of wall thickness from the inside [13:33:13] they're also single pane non insulated [13:33:30] that's terrible, you might as well choke some birds to death by hand [13:34:39] it is however unreasonably large [13:35:32] both the window and the entire apartment [13:59:41] here newer buildings have thicker walls [14:00:31] like my previous apartment had windows with like 15 cm windosill on the inside, triple glass window and another probably 7-8 cm windowsill on the outside [14:01:14] that was built in 2013, my current apartment is from 2005 i think and no massive windowsill on the inside [14:13:57] #KSPOfficial: mode change '+o BPlayer' by ChanServ!ChanServ@services.esper.net [15:10:51] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [15:20:15] Last message repeated 1 time(s).

All the more reasons for JWT [19:43:41] what did it give us tho? [19:43:57] Let me get you that gallery of pictures [19:44:04] >3000 exoplanets [19:44:11] they weren't there before?! [19:44:14] BPlayer: uh. [19:44:25] no, they spawned when we observed them, obviously [19:44:42] that also explains why the earth is only 12000 years old [19:44:47] We did not know where they were until we observed them, and now we don't know how fast they move [19:44:55] i wonder if we'll ever find a way to get to those planets [19:45:11] falalilal: we knew about a few hundred before. We have a much better understanding of planets especially within 1 au of their stars now. [19:45:18] how long ago are we seeing them tho? [19:45:27] Also astroseismology [19:45:41] a few hundred years tops [19:46:06] Kepler planets are generally a few hundred ly away, but a few might be >1000 [19:46:39] in astronomic timeframes, that's basically yesterday [19:47:12] if it was just a few seconds after midnight [19:47:29] i'm literally sitting here right now and somehow getting annoyed at the fact that we haven't found other intelligent life yet [19:47:54] don't read up on fermi's paradox then [19:47:56] c'mon scientists, get on with it! [19:48:40] Humm, I can't find that gallery [19:49:01] There were those APOD images with the best discoveries of, I believe, Kepler [19:49:20] Or was that a different observatory they nominated this way? [19:49:23] Intermittent reminder that Earth's strongest radio signals were Soviet ballistic missile early warning radars. [19:50:00] everything is bigger in russia [19:50:17] Russia is bigger, so everything in Russia is bigger too :P [19:50:17] so why not radio as well [19:50:33] its a tragedy that the Americans tricked Osama into fighting communism for them [19:50:37] There is a certain beauty to it, though.

[19:55:57] Nah, not a 20s movie. Charlie Chaplin is missing [19:56:45] but they had sound in 50s movies [19:57:09] also, they figured out proper fps [19:57:33] btw 1.6 is coming [19:57:41] winter is coming? [19:57:46] i'm still on 1.4 [19:57:47] could be more correct to call it 1.4.7 or something [19:58:21] they could be going the java route and call it 6.0 [19:58:28] hehe [19:58:40] or the chrome way and call it 60 :) [19:58:43] KSP 6.1, AKA KSP Vista [19:59:06] 1.5 is so minor it doesnt even have a trailer [19:59:07] Whoops, no, 6.0 would be Vista [19:59:18] 6.1 would be KSP 7 :P [19:59:59] BPlayer: that's still not as bad as windows 10 having two different counting systems, and both are used to communicate to the user [20:00:09] hehe [20:00:45] That's what happens when a program grows organically [20:01:44] i haven't used Windows in years [20:01:54] but I guess I shouldn't mention the communist Linux LOL [20:02:27] Discussing OSes is fine as long as it doesn't turn religious.

INCONCIVEABLE [20:05:17] as long as you keep it in an atmosphere without water, preferable in a vacuum [20:05:22] oh wait, no cooling then [20:05:29] It's what I was issued for work porpoises [20:05:37] (the iMac) [20:05:48] Also, lol [20:06:15] Warranty void if you touch the keyboard or look at the screen [20:06:22] hehe [20:06:41] pp bus g3 hot [20:06:59] Main B bus overheat :P [20:06:59] Bonus: "fun" that involved using IRAF and DS9. [20:07:16] undervolt [20:07:20] Undervolt in main bus B [20:07:25] if you mean apollo 13 [20:07:54] pp bus g3 hot is the typical power line in a mac that fails [20:07:56] I mean Apollo 13 fitted to your pp bus g3 hot comment [20:07:56] oh wait, no cooling then <-- you can have cooling in vacuum (by radiation) [20:07:59] because of reasons [20:08:14] yes you can have, but normal computers are not designed for that [20:08:21] neither for zero g [20:08:32] so they would overheat in space [20:08:37] Sure, the hard drive disk starts floating in zero g :P [20:08:53] i don't think there's much of an issue with zero g [20:09:04] The LCD spills [20:09:05] i mean, they have random consumer laptops on the ISS [20:09:24] Action: BPlayer stops talking trash :P [20:09:30] Computers have fans. They don't rely on gravity assisted convection. [20:09:33] anything you can use upside down you can also use in zero g [20:09:43] Well, there are some passive coolers, too. [20:09:49] hey now... i love that speak about making my PPBus G3hot. [20:09:59] Eddi: Not quite. Convection might be an issue, but mostly they have fans [20:10:00] heat sinks* [20:10:12] Heat rises, though [20:10:12] there is an issue with zero g, there is no thermal convection, because there is no up [20:10:14] :P [20:10:15] same for flames too [20:10:43] just means you need some other way to induce some draft [20:10:52] like a fan [20:10:55] somewhere [20:10:57] anywhere [20:11:07] Let's build a computrifuge! [20:11:33] Well.. could use LEDs in 0g... they don't produce heat [20:11:34] computerfrugal forces? [20:11:44] everything creates heat. [20:11:55] entropy must always increase to the maximum. [20:12:09] Entropy may increase in processes that consume heat [20:12:39] It's rather rare, but it happens [20:12:50] did you mean decrease? [20:13:04] tell that to the people who install LEDs in stoplights and when snow covers them up [20:13:34] LEDs in stoplights are heatsinked way more than the heat they produce. [20:13:44] JVFoxy: There are heatable stoplights for that. [20:14:12] may as well just go back to regular bulbs [20:14:28] they figured, installing LED would save on power... ya till winter rolls over [20:14:31] running a heater for a portion of the year is still cheaper. [20:15:01] do what they do with Voyager, install radio isotopes.. radiation gives off heat. no power needed [20:15:08] incandescendents are only 5% efficent for light output. [20:15:20] yes, laughable [20:15:22] tell that to the people who install LEDs in stoplights and when snow covers them up <-- just because they produce 1/10 of the heat doesn't mean they produce "no" heat [20:15:30] Can also use radioisotopes to make the lights light up :P [20:15:36] they produce no USABLE heat. [20:15:47] just install radon in everything, ez. [20:15:51] I just saying, everyone seems to think LED's are heatless... you should see the heatsinks on some massively big LEDs [20:15:58] hehe [20:16:05] on really bright power leds [20:16:17] the most of the thing is the heatsink [20:16:19] leds is weird on heat, it emits light one side and other side gets heat [20:16:27] they figured, installing LED would save on power... ya till winter rolls over <-- it's only "winter" for a few days each years, difference is you can turn off the heating on the other days [20:16:27] was at a homeshow... some of the LED lighting systems they use for pools, a good portion of a KG is just a metal block with fins [20:17:25] find it funny, some places that have soda vending machines where it gets really cold in winter, they use regular bulbs to keep the soda from freezing up [20:17:42] hehe [20:18:35] in any case... [20:19:24] Last time I stayed for a night in a hut in Sweden, there was no heating. We put a pack of milk in the fridge overnight, had to get up at 4 in the morning, and we had 6°C inside of the hut. The milk froze, we had to drop solid chunks of it into the cup [20:19:28] Also LEDs last much longer than incandescents. That saves a lot of money/work. [20:19:31] ya I don't get much of a winter where I live.. just lots of rain these days. Power by hydro dams... [20:20:18] just careful what LEDs you guy.. sometimes the soldering connections aren't always teh best [20:20:23] i have easier solution, i dont drink milk :) [20:20:25] incandescents last a few thousand hours, even high intensity LEDs can last more than 10x that, even approaching 100,000 hours. [20:20:26] ... what LEDs you buy [20:21:18] fire station has a bulb still going after decades, but thats only because its a low power, low pressure [20:21:56] I bought tiny smd LEDs, 5 mm white/violet, high power white/365 nm UV, ... [20:22:05] think we expect a lot out of things we make these days... most of it doesn't last as a result [20:22:19] Are those like those old pyramid-scheme bulbs? iirc Amway or something... they were repackaging 220v bulbs as long-life 120v bulbs. [20:22:25] they also suspect that bulb lasted so long due to lucky factor plus that that light basically never gets turned off [20:22:56] rolf thermal shock is a thing in bulbs.. [20:23:21] yep [20:23:23] room temp to several hundred degrees in a split second [20:24:06] several thousand degrees you mean. [20:24:12] that tungsten gets kinda hot [20:24:17] white hot, as it happens [20:24:29] you're literally getting blackbody radiation. [20:24:36] 2300 K? [20:24:40] k. [20:24:50] there are old old gas engines that still survive, even run.. can even put them on cooking oil.. but nope... don't want them, they pollute too much. They'd rather just buy out lithium mines, metal shops, spend billions on making electric cars, have to replace batteries every 5 years [20:24:57] halogen maybe 3000 K [20:25:26] don't remember how hot they get... they were going to make 100w bulbs illegal here [20:25:39] then start pushing down to 60w.. 40w... [20:26:04] LED are cheaper anyways, in the long term. [20:26:22] they started finding flouro bulbs were causing too much UV [20:26:30] here we can buy 40w ones, I think they dont plan to make that one illegal, as there is couple uses that cannot use led period [20:26:31] eu did stop production of 100w and even lower incandescents [20:26:33] or the fact that they contain mercury [20:26:42] actually a good thing, we dont need the heat from them most of the time [20:26:42] mercury is kinda bad[citation needed] [20:26:53] incandescents last a few thousand hours, even high intensity LEDs can last more than 10x that, even approaching 100,000 hours. <-- i had to go out and buy 4x2¬ halogen bulbs every half year or so, until i swapped them with LEDs some 5 years back [20:27:00] haven't had a problem since then [20:27:10] Citation: Karen Wetterhan [20:27:24] hahn [20:27:30] cock [20:27:46] the only place i use halogen bulbs, the stove hood for light intensity while cooking, and one of those halogen replacement bulbs that gives me more light output without pulling too much amperage. [20:27:56] everything else is LED. [20:28:00] how did Hahn/cock get so many different meanings? [20:28:13] exactly. oven lights just cant be led [20:28:14] as any other word [20:28:25] led need to radate away heat, and oven pumps heat in [20:28:26] (LED and fleuroescents' circuitry isn't good in damp locations) [20:28:28] there are lights in ovens? [20:28:34] sigh.. was ads going around over here, trying to get people to not use AC units.. open your windows, use fans. Don't drive.. ect. Times I wonder this whole energy saving craze gets a little out of hand [20:28:37] yes. [20:28:44] LEDs make much sense in bicycle lighting. [20:29:12] JVFoxy: it's both getting out of hands and isn't nearly enough at the same time [20:29:14] bicycle repair man! [20:29:18] would love to get one of them bike generators from the old days. Make wind generator [20:29:35] how would that be any better? [20:29:39] JVFoxy: AC have two problems, it uses lot of power, AND it can leak gas that damages ozone layer [20:29:42] it generates drag as you go [20:29:50] JVFoxy: Fans wouldn't turn fast enough. [20:29:54] so you have to put in energy to drive it [20:29:56] Althego not for a bike [20:30:26] acs are not using ozone layer damaging working fluid anymore [20:30:28] for daced [20:30:32] JVFoxy: you mean those generators that generate 2W of power? [20:30:46] but the replacement is a greenhouse gas :) [20:30:47] Action: UmbralRaptop isn't sure how open windows help on those 32+ C days, but okay [20:30:48] JVFoxy: what kind of thing do you want to drive with that? [20:30:57] actually the ozone layr almost completely fixed itself [20:30:58] 2w is plenty for small led lights [20:31:03] R134a (iirc) has been out for decades [20:31:04] 3W [20:31:10] Althego: yeah and we'd like to keep it fixed [20:31:12] I use fans... despite room mate giving me grief for not getting an AC [20:31:21] i had a 1998 chevy lumina that uses R134 and not freon. [20:31:21] Rolf: yeah, bikes are much brighter nowadays than they were 20 years ago [20:31:50] Eddi|zuHause just to mess around with. My camper could run on 2 watts for lighting if I replaced the 4 bulbs with LED [20:32:00] Eddi|zuHause: I wish thats true here also. I almost tagged darktards 2 times in road. black clothes, dark bicycle. [20:32:02] my new bike is just as stupid as my old one [20:32:09] hehe [20:32:15] darktards [20:32:20] zero lights [20:32:27] actually the ozone layr almost completely fixed itself <-- uhm, there are signs of the ozone layer regenerating, but i wouldn't call that "completely fixed" [20:32:44] Around here, if you want AC for the summer... with the costs of heating in the winter... your energy bill for natural gas + electric would be $300+ per month... if you don't have AC here, it drops to like $40/mo in the summer. [20:32:49] Althego: thats what they call people that has no lighting in burning man. I never went, but loved that word. [20:33:05] also, they found a new (probably chinese) source of ozone-layer-eating chemicals [20:33:07] its super super dark there so its good idea to have lighting [20:33:33] one time i was in stolberg and was walking to the office from the hotel in the morning. it was winter so it was fairly dark, and i realized i had completely black clothing on by accident [20:33:41] you can power a few watts of LEDS for a LOOOONG time off of even a motorcycle battery. [20:33:45] power company over here been trying to push for stupidly high rates for years... already getting carbon taxed through the roof on fuels. Government says they want ot use it for things, but no one knows where that money is actually going [20:34:06] hehe, typical government [20:34:21] already paying highest prices on gas of north america [20:34:31] well.. other than Churchill [20:34:32] If usage is blank, its rich cronies bank accounts. [20:34:33] naa... more like typical private utility companies. [20:34:57] Churchill only because rail line got washed out, having to fly everything in till rails fixed. Been out more than 16 months [20:35:09] JVFoxy: a few years ago there was huge outrage in america about fuel costing "4$ per gallon"... i ran those numbers through a calculator, and fuel around here was twice that [20:35:35] average transit time in usa is twice yours also [20:35:38] or more [20:35:38] I've seen $1.64/L here... [20:35:39] i'm still pissed that they removed commuter rail service around here like 40 years before i was born. [20:35:51] I know europe has it far far worse... something liek 2.50/L? [20:35:55] Eddi|zuHause: You live in a country with a transit system, though [20:36:10] yes usa has really low fuel prices [20:36:17] transit system here too.. but too much in-fighting [20:36:25] here mre than half of it is taxes and stuff [20:36:31] im lucky, drive time, when no traffic, is 12 minutes. most of coworkers transit time daily is hour long. there was one that was 4 hours long (he brings camper and lives at site for working weekend) [20:36:31] most of the larger cities in the united states actually had good transit systems before the auto companies kinda shoved them out. [20:36:41] yep [20:36:52] detroit had trams. [20:36:55] Rolf cool.. I'd be doing that too if I wasn't being bounced around different sites [20:37:08] Skytrain here [20:37:09] well, fuel prices were actually pretty low the beginning of this year. until trump rallied up against iran again [20:37:11] and around here we had commuter rail to the nearest 4 cities. [20:37:23] JVFoxy: ehh not really great, he had no power in his camper [20:37:45] all this may be interesting, but i really need to sleep. why is it that you people start to talk when i want to go to bed [20:37:46] he evenually got another closer job [20:37:50] lol [20:38:01] they want to expand through my city's area (finally we get some attention this side of the river) but can't decide if regular skytrain or LRT.. [20:38:08] most of the larger cities in the united states actually had good transit systems before the auto companies kinda shoved them out. <-- it's a bit more complicated than that. many tram systems were run by people trying to cash in on land development deals and were never meant to run on a profit themselves [20:38:16] they're talking about lightbulbs tho lol [20:38:21] so after the land was sold, no maintenance was put in [20:38:42] and they were totally run down by the time "the car companies killed them" [20:39:00] Rolf not having power not really a big deal for camper. There are ways to remedy it, costs a bit though. Solar panel, controller, battery.. got one myself. [20:39:16] well, being in michigan... the car companies almost directly stopped them. [20:40:17] tram systems were shut down all over the world, even in places where the car companies had less direct control over them [20:40:17] while browsing library DVDs: "What killed the Electric Car?" next to "Revenge of the Electric Car"... hmm... [20:40:48] the king is dead, long live the king? [20:40:59] Our area had urban electric trams that went way out... Skytrain actually runs along a good portion of the old line [20:41:00] what killed electric car? batteries. [20:41:15] hopefully there will be huge breakthough on power storage [20:41:43] tram systems mostly held up in eastern europe, because it was not easy to get proper replacement [20:42:03] (by those standards, i live in eastern europe) [20:42:06] not a huge breakthrough, unless you don't look for a while. it always has been a series of incremental changes. [20:42:09] Rolf company that made the EV1 electric car decided it wasn't worth the money to invest in the technology. Cars were only leased out to people, then recalled and destroyed. One or two were saved but only after the company had gone in and destroyed the power controller system [20:42:57] Rolf: what happened to hydrogen fuel cells? [20:43:16] its not great. hydrogen is most diffult gas to store [20:43:22] still being developed.. a couple of companies out here still working on them. Even been testing buses on them [20:43:34] the costs associated with storage and transfer of hydrogen makes them about the same as battery electric cars. [20:43:48] and explosive as additional fun [20:43:58] https://youtu.be/rppuoZ198B8 [20:43:58] YouTube - Heavy Hoempa - Ace of Spades [20:44:00] no worse than having propane [20:44:02] pressurized gas cars is interesting but limited range [20:44:06] though hydrogen is safer than propane [20:44:20] hydrogen when escaping, goes up into the air... propane pools below. [20:44:55] except that hydrogen needs to either be cryogenic, or pressurized to thousands of PSI. [20:45:03] pressurized gas cars is interesting but limited range <-- in the old days there were "fireless steam engines" [20:45:20] in the old days, there were flywheel driven busses. [20:45:25] they were filled up with hot gas every now and then, and ran on that [20:45:30] I was talking to a friend about what became of steam cars... there was one late model, 5 minutes to warm up steam generator, as opposed to half hour for boiler system. nearly same fuel enconomy as gas [20:45:54] he said, at one point, people thought steam system was too dangerous. Then added, like having a tank of fuel under your seat was any better [20:45:59] but muh low RPM power. [20:46:18] steam had massive amounts of torque... super quiet [20:46:22] it's so weird how even 100 years ago seems like an entirely different world in terms of technology [20:46:31] you can get torque anywhere, the power is what matters. [20:46:37] low RPM power is where it's at. [20:47:08] Jay leno had his car running on the highway, said it felt like it drove very happily there [20:47:31] cars don't feel emotions tho [20:47:39] even joked about the funny faces people made when they drove by, didn't hear a thing.. wasn't electric, just tiny bit of steam off the back [20:48:12] Eddi|zuHause: interesting. https://en.wikipedia.org/wiki/Compressed_air_car if youre interesting on reading more current version [20:48:42] falalilal Some of the older steam cars, using boilers, would run out of pressure on the highway. Had to stop, let things build up again after a while. The generator car would go, actually ran better when it was kept going. [20:49:47] Rolf flower market in China I think uses a fleet of air powered cart type cars [20:49:49] why didn't they just hook up a steam pump to one of the wheels to pump more steam in? [20:50:34] why don't they put a fan next to wind plants to get more wind power? [20:50:54] turn the whold world into a generator wheel [20:51:18] my research station has weird shadow on it [20:51:24] the better question is... why don't they use a gravity feed for that 60 tonne genset to store power for peak times on off-peak wind conditions [20:51:24] there are tidal power plants [20:51:46] KrazyKrl like hydro dam? [20:52:10] oh, sorry. my suggestion was actually resonable :p [20:52:55] i wonder if they used tital power generators on a large scale, the days would actually get noticeably longer [20:53:05] using power to force feed something to store power... then to use that power to feed the grid... might be better to just generator power when needed. Rather than dealing with double losses [20:53:19] and then they have discussions about "but the days have been getting longer in the past" [20:53:29] lol [20:53:43] wave generators... [20:53:54] *tidal [20:54:07] lots of ways to produce power [20:54:16] Just take one of those silly water-main turbines... and stick them in the sewage lines. ezmoney. [20:54:46] KrazyKrl: you can do that in cities skylines :) [20:54:58] KrazyKrl don't knock it... one village out here already uses heat from sewage to heat homes. Said sewage from 3-4 homes can heat one place [20:55:20] JVFoxy: but that's "biogas" [20:55:38] JVFoxy: not "use the kinetic energy of flushing toilets" [20:55:39] i mean... it's actually cheaper to run a heat pump out of your basement air to heat your water, than it is to actually burn fuel or use electricity. [20:56:03] technically the could biogas but thermal energy.. take a hot shower... system extracts the heat from the water [20:56:27] just line all consumer sewage lines with thermocouples? [20:56:31] wish the poor kerbals luck, i'm about to send them into an impromptu solar journey - they might starve if I can't get back in time. [20:56:50] Just land them on the sun. [20:56:59] take a surface sample. [20:57:11] there is a place I worked on, they took it further. Coiled copper pipes around some of the drain pipes.. when you took a shower, the heat of the water going down, pre-heated the water going to the heater [20:57:51] i mean... concrete plants use preheaters to save like 90% of the costs of heating the clinker. [20:58:17] preheaters are totally not a new invention [21:00:46] well... couldn't that actually be a resonable modification to a hot water heater heat pump? something like a line of alcohol or something that gets curled around the waste lines, and is cooled to about 50f via the hot water heater [21:02:05] some people have built their own heat storage system, using a water system. Heat is drawn off panels on the roof, used to heat the storage tank. Then water going to the house hot water tank goes through a coil in the heat tank. [21:02:25] that's just hot water solar, and is as old as piping. [21:02:52] Why not use a heat exchange mechanism at sewage lines which would retain the heat in the home in the first place? [21:03:03] we built a solar water heater back in school [21:03:07] BPlayer some places already started doing that [21:03:38] heat storage tank also allowed them to heat the house, along with preheating the water to the hot water tank. [21:03:51] Sounds much easier to me than somehow try to harness the heat from the sewage and transport it somewhere else [21:04:25] Definitely cheaper on infrastructure [21:04:44] BPlayer the place that did it over here first, it was more a test setup... found out takes 3-4 homes to gather enough energy to run heat for 1 home. [21:04:55] "transporting heat somewhere else" seems like a terrible idea, unless you're talking about really big scales (like using the heat output of a power plant to heat an entire city) [21:05:05] Let's run a ponzi heat scheme, then :P [21:05:35] "your house could be warm if you recruit 3 new members"? [21:05:59] well.. what they more likely do is recover heat from a set of homes, devide the recovered energy back among them. It was just more a way to give an idea how much is involved [21:06:07] Sign up for heat at 200% interest rates today!!! [21:06:25] :P [21:06:52] ... when you start talking about using liquid salt for heating.. you know you talkin about serious heat [21:07:13] Well, heat is a terrible form of energy to handle [21:07:32] There are reasons for using Electricity for so many things :-) [21:08:21] transfer energy through mechanical means has its own problems too [21:08:29] sentinals are like free income aren't they? [21:08:33] On an SSTO if i have extra/full oxidizer is it better to burn Rapiers until it's gone, or just use nuclear, or use both? [21:09:19] mec: Nuclear engines generate much more delta v per unit of fuel than Rapiers [21:09:37] I believe this still applies if you just "waste" the oxygen [21:09:38] BPlayer: depends on which salt, some salts cool when dissolving in water, and some heat up. however, the most common usage of salt in winter is to just lower the freezing temperature of the water [21:09:39] true but does that counteract the weight of the oxidizer? [21:09:56] yes because you also burn fuel with the rapier [21:10:03] NERV is also super inefficent because its mass is over 2 tonnes. [21:10:13] mec: If you give me numbers, I might run a quick calculation which effect offsets which [21:10:34] I need the ISP of the Rapier in the mode you use it and the ISP of the nuclear engine [21:10:52] like 240 and 800 iirc? [21:11:14] 305 vac wet [21:11:57] ship is 42,895kg, 3040 units of liquid fuel, 1320 units of oxidizer [21:12:08] that's total weight including fuel [21:12:56] with TAC fuel balancer, you can just "dump" the extra oxidizer and run the nukes [21:13:05] mec: What's the ISP, though? [21:13:38] 305 rapier, 800 nerv [21:13:44] ya [21:14:20] Except you don't even need oxidizer if you run jets+NERV [21:14:32] but you pay a premium with that 2250kg NERV. [21:14:40] if I ever get NERV into space.. I'll probably keep it there, use it to run a tug or something. [21:15:22] fuel only SSTO with jets and NERV... its tough, doable but doesn't really give much space for cargo or anything [21:15:26] i've wasted a few NERV tugs by disconnecting from them in unsuitible orbits [21:15:28] 3000kg nerv(its bee a while) [21:15:34] I refilled on a moon, I probably should have just got liquid fuel but I got oxidizer too [21:16:02] yea... unless your SSTO is pushing the limits of the physics engine; the NERV is one of the worst engine choices for an SSTO. [21:16:39] a propos moon, does the death star emit enough gravity to keep something in orbit around it? [21:16:46] mec: Oxidizer and LF have the same mass per unit. You need 11/9 units of Oxidizer per unit of LF for the Rapier, so you will use 1320 + 1080 = 2400 units of mixture to burn the rapier [21:17:44] Everything has enough gravity to form an orbit... it's just the orbit might be a little unstable. [21:17:47] whats the calculation for deltaV? isp*9.8*ln(full/empty)? [21:18:22] That should give you a (fictious unit of impulse) of 305 * 2400 = 732 thousand with Rapiers, vs 1080 * 800 = 864 thousand with NERVAs [21:18:31] "keep in orbit" implies some sort of stability [21:18:32] for a 150km deathstarbasestationship, it certainly has a non-small gravitational pull. [21:19:34] mec: If you were to burn only the fuel that goes with the oxidizer, the NERVAs win with impulse. But given that there is more fuel left, you'd have to use it to drag the oxidizer along [21:19:37] Rapier is 2000kg, NERV is 3000kg. Rapier also can be run dry mode in-atmosphere. [21:20:02] and the rapier's dry mode fuel ISP is like 3200sec [21:20:04] mec: My estimate is: Burn the oxidizer off with the Rapiers first [21:20:20] BPlayer: but you have less liquid fuel for your NERV when you do that [21:20:24] Your formula for dV is correct [21:20:41] falalilal: If you looked carefully, that's what I just calculated [21:20:49] I don't do maths [21:20:52] deathstar.... 100-160km version 1, 160-900km for second.. depending on source (wiki) [21:21:26] arguing hard science in a science fantasy franchise is a little... useless? [21:21:44] falalilal: This effect gives you about 18% extra delta-v. Which, I believe, would be more than offset by the fact that you'd still have all that oxidizer to drag along [21:22:01] arguing stuff in a computer game channel is "not useless"? [21:22:15] and fuel/oxidizer? weights 5kg per unit [21:22:39] mec: Yes [21:22:55] Let's calculate thoroughly, then [21:23:20] If you first burn all the fuel with rapiers, then burn all that's left with NERVAs, vs if you only use NERVAs [21:23:25] some reason I thought NERV was 7tons.. [21:23:37] NERV? Not NERVA? [21:23:49] NERV is 3000kg. Rapier is 2000kg [21:25:35] doing rapier then nerv: 305*9.8*ln(42895/30895)=980.9 + 800*9.8*ln(30895/21095)=3000 [21:26:19] I might be thinking something else.. or a mod I once used [21:26:26] just nerv: 800*9.8*ln(42895/27695)=3430 [21:27:03] mec: You can use ;calc in this channel :-) [21:27:31] how would you calculate using both at the same time? [21:28:14] use more parenthesis [21:28:21] You need the thrust of both engines for a weighted average [21:28:34] KrazyKrl: what do you imagine would be a good use of our collective time? i feel like everything I do is just about waiting for death. [21:29:17] hmm nerv is 60, 4 rapiers is 720 [21:29:28] That is, engine a has an ISP of 100 and a thrust of 4, engine b has an ISP of 200 and thrust of 6, weighted average would be 4/10 * 100 + 6/10 * 200 [21:29:55] That's what you take for the ISP value, at least [21:30:12] deathstar.... 100-160km version 1, 160-900km for second.. depending on source (wiki) <-- the problem with that number is the death star is not solid metal, so you can't easily compare it with similarly sized actual moons [21:30:40] Keep in mind this applies only for the time both engines have fuel. The Rapier runs out of fuel soon, though, so you end up having another phase of NERV only [21:31:41] I believe this will yield less dV, though [21:31:52] I should sharpen my sword again [21:32:08] ya 4 rapiers use 26.48 oxidizer/sec so they will run for 49.8 seconds [21:32:22] Eddi|zuHause I don't know... realize when the movies were being made, was back in the 70's.. we had only just started doing more space related things in the real world. 'Moon's, probably meant something more akin to 'Earth's moon'. Honestly, I fell a bit from the franchise a long while back. [21:33:16] Because if you use the rapier (lowest ISP engine) first, you burn lots of fuel away, then use the high ISP engine and little fuel for lots of delta v. If you use the high ISP engine first, you burn a little fuel and have to haul the bulk of it for the high ISP engine [21:33:32] So you want to use the low ISP rapier first [21:33:42] Well, if you treat it more like fantasy with dragons and space voodoo; you can have some fun. If you treat it like harder science fiction, you're gunna have problems. [21:33:58] What /might/ make sense is burning part of the oxidizer off with the Rapier and using the NERV with a little extra fuel [21:34:04] JVFoxy: i won't discuss the movie-usage of the word "moon" here, but certainly we knew about a few dozen moons even in the 60s [21:34:28] that seems like it would be hard to calculate [21:34:56] Yep, tuning the oxydizer load in SSTOs is pretty important. But remember that NERVs aren't really intended to be high TWR, low dry mass engines. [21:35:08] what about the kash value of the oxizider? maybe you want to save it and bring it back! [21:35:28] Jupiter, Saturn.. outer planets [21:35:32] You'd have to make a function of total delta-v a sum of the two individual burns, and make it depend on the percentage of oxidizer you use for the Rapiers. Then minimize the function [21:35:32] just mine some LFO out of the fuel tank at the landing pad, ezmoney. [21:36:16] any case.. someone said Deathstar seemed to have no 'outside gravity'... considering its size.. [21:36:21] is that possible? [21:36:44] when i last played, you could get LFO out of the KSC fuel tanks via a drill. [21:36:51] lol [21:36:59] i've never actually used a drill [21:37:01] LOL [21:37:20] So no Ore mining and processing, but direct LFO mining? [21:38:24] "when i last played", is that before or after 1.0? :p [21:38:25] forget middle guy.. straight to the source [21:38:46] before 1.0 maybe [21:39:00] it wasn't too much after resources were actually added, lol. [21:39:33] (when i got the game, it was on 1.0.5) [21:39:33] "last played 4/22/2013" uhh... oh my. [21:39:55] some recent steam update broke the date format :/ [21:40:17] KrazyKrl: so you're in this channel, telling people how to enjoy talking about a game that you haven't played in 5 years? [21:40:33] rocket science doesn't change. [21:40:34] falalilal: that's really not so uncommon [21:40:47] and the game is after alpha, so the major features should be frozen. [21:40:52] falalilal: if you've been to a few gaming channels [21:40:57] i get 4039dV from both then nerv, 3981dV from rapier then nerv, and 3430 from just nerv [21:41:09] thats weird, i would have also expected burning all the oxidizer first would be better [21:41:22] you can't use just the NERV, since you need a dry jet engine to get you there. [21:41:28] im on minmus [21:42:42] does the just nerv portion count jettisoning all oxidizer and using just the NERV? [21:42:54] no, i don't think you can do that [21:43:00] with mods you can. [21:43:18] i guess i could burn it all up and then mine some more LF [21:43:47] i mean... if you're running a fueling station, wasted dV literally does not matter before takeoff. [21:44:26] or you could just, say, transfer the oxy out of the craft, and launch with LF only. [21:45:04] burn the oxidizer while grounded [21:45:40] there is no reason to burn it off if you can transfer it into a tank. [21:45:53] maybe he can't tho [21:46:13] [30:17:43:18] i guess i could burn it all up and then mine some more LF [21:46:18] "you touch it you buy it, no refunds" [21:46:21] e.g. there is tank space with some LFO [21:46:32] #KSPOfficial: mode change '+v eriophora' by ChanServ!ChanServ@services.esper.net [21:46:40] my mining rig is part of my spaceplane [21:47:05] you've got some crazy designs lol [21:47:22] oof... running a NERV and ISRU stuff must dumpster your cargo capacity. [21:47:35] lol wuts cargo [21:47:39] exactly. [21:48:02] unrelated: i've been meaning to ask, can i edit actions (1-9, light, gear, etc.) while in flight? [21:48:25] only with a mod [21:49:04] because i can't see any gameplay reason why that should be restricted to VAB [21:49:52] i mean... there might not be an elegant way of adding it? [21:50:00] even though KSP has been out for like 7 years. [21:52:49] trying to clone this thing's SSD because I wanna try something else with it. [21:58:37] that sounds like a "famous last words" entry [22:01:08] uff... whoops, forgot a bigger RW.. this is going to make for interesting landing on mun [22:01:59] at least with high polar orbit relay.. radio connection will last a tiny bit longer [22:04:24] well, that's when you send up a multiple microsat in which you decouple and make differing mid-course corrections to deploy the communications cluster on the same day. [22:09:37] ... huh? [22:13:15] MIRV, but instead of nukes, they are comsats. [22:14:22] (but everyone knows that project Eeloo should have never been cancelled) [22:14:24] candy canisters [22:14:35] oh I upgraded the koyuz a bit as well [22:15:15] "please do not moisten the fairing plate" [22:15:23] heh [22:15:39] I changed the booster separation a bit and made a new vessel [22:15:51] with a nice escape system [22:16:28] KrazyKrl here: https://youtu.be/n2eBwgW6sig?t=1m10s [22:16:46] btw.. who says you have to do mid-course corrections?

[23:32:48] Maintenance costs? [23:34:18] sorry, just small part of a bigger idea I've got... this wouldn't be at kerbals own home world [23:35:28] pad is shared resource with some another NPC angency... [23:36:43] altho.... launching from a pad, depending on size of craft could incur repair costs after each launch for more 'stock game'. [23:47:06] extraplanetary launchpads might have this feature. [23:52:54] I've also considered a station or two in fixed orbit from another agency you could fly up to
