The Unofficial Kerbal Space Program Forum Steam Group
lajoswinkler replied to Volcanix's topic in The Lounge
Let's bump this up. Folks, if you want realtime help with KSP or just want to chat about it and spacey stuff, or anything actually, join this Steam group. It's fun. We've got candy. -
Is it so hard to use the search engine? No need for one more thread.

I never heard of proof that it has any impact, and I see no mechanism of action for such thing to occur. If it's ultrasound, I don't see the problem. If it's high pitch, but audible, it's rather low intensity so it would annoy at best. Like a mosquito. Electronics shouldn't produce such sounds. Sometimes they do and it means something inside is about to fail or has failed. I know, but I was talking about surface dwelling humans. We are constantly showered by cosmic rays and secondary radiation. It would be interesting to see how much damage it induces to our retina in one lifetime. Yes, that's one of the stupidest myths coming from eastern Asian countries. Another one is obsession over blood types.

Metallic Oxides--->Oxygen+Metal?
lajoswinkler replied to _The_Burn_'s topic in Science & Spaceflight
Air oxidizes hot metals. In vacuum, there'd be no need for covering the molten metal with dross all the time. That's the good part. The bad part is that lots of energy during electrolysis is spent on heating, and while that waste heat is easily vented on Earth by convection or air and conduction (actually, sometimes the problem is to save the heat, hence refractory material to insulate the reaction), in space it can conduct to the regolith poorly. The main path is radiative, but that's very inefficient, as we all know. Look at how many radiators ISS has, and it deals with a lot less heat. It would require serious chem-enginnering study to figure this out for a particular problem, but on the top of my mind, I'd say it would be very difficult to make such plant. -
Thanks, I'll check that out.

And there's your problem. Sleeping in unnaturally hot air causes problems. That's actually both valid and proven. Turn off your computer or, if you must keep it on, open the windows or something. Hot dry air and light (especially flickering and bluish) are known sleep deprivators.

That's one of the stupidest sites out there that looks somewhat legit. That makes it dangerous.

Energy requirements for production of aluminium is insane. We're talking about hundreds of kiloamperes of current at few volts of operation. That's a lot of parallel solar panels. I mean a lot. What about heat management? Hall–Héroult process goes at some 1000 °C and deals with evaporating fused coke anode. The heat involved is enormous and dealing with it in vacuum is a PITA. It's a chemical engineer's nightmare.

Metallic Oxides--->Oxygen+Metal?
lajoswinkler replied to _The_Burn_'s topic in Science & Spaceflight
You do realize that aluminium, when it reduces iron from its oxide, is oxidized into aluminium oxide? You don't get 2 refined metals. You get zero. Iron made by such reaction is very dirty. -
Aluminium is not laying around the moon. Aluminium compounds are. They are extremely difficult to process to isolate the metal out. Aluminium producing industry is one of the most intensive consumers of electricity.

Or skull. They can hit the eye from just about any direction. I wonder how much damage a human retina receives after a lifetime from cosmic rays alone...
-
Exactly. If you copy a brain and kill any of those two, original or copy, you're killing a person. That's why teleportation would require murder.
-
I do. Jool didn't remove any of it... Others have suggested it might be Laythe's aditional atmosphere components, but I don't think that's modelled, it sounds weird to me. Air in KSP is one thing which has or has not IntakeAir property.

Rosetta, Philae and Comet 67P/Churyumov-Gerasimenko.
lajoswinkler replied to Vicomt's topic in Science & Spaceflight
7.8 km from the surface, 66.5 cm/px at closest surfaces. http://blogs.esa.int/rosetta/2014/10/20/cometwatch-18-october/ Neck of the comet, where the outgassing is the most powerful. Some of these dots are probably particles orbiting the comet. -
If ice were to form inside cytoplasm, it would completely wreck the cell from inside out, snapping organelles and piercing the plasma membrane. Upon thawing, the cell would look like a pierced water balloon. Bacteria love that because no effort is needed to collect the nutrients and that's why thawed food spoils fast. The cell must always remain in the gel state and even then, there's sluggish movement of certain parts of the mechanism. Think about it. If everything stops, the frog could be kept in such conditions indefinitively and then revived. That's not the case. You won't be able to wake up a frog frozen for a decade. The longer the frozen period is, the less chances are you'll succeed. That means something is happening inside its cells, which is obvious because we're talking about temperatures a bit lower than the freezing point of water. That might seem ungodly cold to us when we fall through ice into sea or lake, but it's perfectly warm for very slow biochemical reactions. It is certainly not death. It's extremely slowed down metabolism. High organ functions such as contractions of the heart muscles, peristaltics of the colon, that will stop.

Well that seems to be the case. Weird, huh? There aren't just stock parts here (the tanks and the main shield are made by Procedural Parts mod, solar panels are by Near Future Electric, there's one ALCOR pod and an original Mk1 Legacy pod; it was built in three steps and strutted using KAS afterwards), but here's the screenshot of the ship anyway. You'll notice there's an RTG sticking out of the shielded cone. It stays fine at Jool aerobraking, but to be certain it's not gathering heat and transfering it to any part of the ship, I've removed it after the initial braking incident at Laythe. It didn't change anything. The ship was supposed to enter Laythe's orbit, deploy a returnable lander and then return to Kerbin after the lander returns the Kerbals. Just out of curiosity, is the shielding area in stock KSP the form of a cone or a cylinder, is the border sharp or has a penumbra, and does DRE change any parameters that might affect it? My ships can have a length more than 25 m, so perhaps that's the problem. Here's two more screenshots of the ship to show the shield is large enough to cover everything. (Ignore the silly Kerbal yoyoing a probe. ) And last question - is there a way to disable the heating temporarily?

OK, but why is my ship overheating if the shield is covering all of it? It's a tested design. The first thing that should fail is the shield, yet the parts of the ship clearly protected are behaving as there isn't any shield at all. They do not show plasma trails, but upon right clicking, you can see the temperature is skyrocketing. That seems like a bug to me.

I have two things to report. Went to Laythe today. Aerobraked at Jool. Plasma and reentry sound start instantly upon crossing 138 km. There is absolutely no transition. It's as someone turned on a switch. The shield was ok. Other parts of the ship, too, as they were all inside the reentry shadow of the shield. Then I aerobraked at Laythe. 4400 m/s reentry speed. The shield went to some 1300 °C and lost 25% of the ablation, but several pieces (some tanks and RCS thrusters) of the ship began to overheat just like there was no shield at all. They've exploded. What happened?

Downloaded it few weeks ago I think, and my opinion is that this is a great mod. It's good to have one more pod, gives more diversity to the experience. I'd suggest you to separate the pod from the rest of the parts. For example, a lot of people probably, including myself, would like to use the pod only. No need for cramming precious RAM with things you don't need, am I right? With Procedural Parts many already use, more tanks just cram the editor, and the engines... I already have more than I'd possibly ever need. I've tested this pod with Deadly Reentry parts. It works with the standard Mk1-2 shield, even though it looks a bit larger. Good work.

It's a difficult question. Cryonics is indefinite and as such, very invasive to the intra- and extracellular protein machines. Those things are of unprecedented complexity, and their high order functions produce a person. If one day we're able to gradually replace matter prone to organic decay with something long lasting and indefinitively self-repairing, then it might be an option. In the foreseeable future, advanced hibernation at non-cryogenic temperatures is the only thing we might expect.

Refer to the table I've posted. If you have a green one stronger than 100 mW, you become a distraction to commercial planes above 11 km. The ray is powerful enough to still be intensive enough after 11 km trip through air where it gets widened and attenuated. Extremely powerful green lasers are the worst combination because 532 nm radiation doesn't dissipate easily as blue, and is not attenuated as red. It's quite penetrating. They are so powerful that can cause a pilot temporary afterimages in his retina even at that distance and even if you just swing the laser over the plane. Today it's easy to build yourself a custom handheld laser with several watts of power. Chinese companies will sell you the diodes without asking any questions. It's not a bad thing - virtually anyone capable of doing such project won't be a jackass. For example, this is a great guy I've been in contact with who does amazing projects. Be sure to check out his channel. Those lasers are usually 10-20 mW. Unless you're right at the airport and pointing at the cockpits, you're fine. Of course, every time you turn it on, check the sky for planes. Aircrafts have signal lights. Spending money on developing such protection is futile, just like building a car what makes your survive a 250 km/h sideway impact. Some things happen so rarely that it's not profitable or useful to develop protection. It's a fact of life we have to deal with...

At the contrary, it's not frozen because its cells secrete compound(s) with antifreezing properties. It is stiff, but not frozen. Metabolism still partially works, but very slowly. Cytoplasm in the cells stays closer to gel than sol form. Today it's a religious subject. When it's used to explain psychological properties of a human being, it becomes a subject of investigation, rather like chakras, auras and other bollock concepts without real life basis. Human mind is electrical in nature. Not a ghouly smoke that can be "sold", "taken", "possessed", etc. As science, philosophy has evolved. It doesn't cling to useless concepts when it tackles real world. The sooner the humanity as a whole starts accepting this fact of human mind nature, the sooner people start being more responsible. When there's a "backup plan" in the form of a soul, people like to think their actions towards the body are a lot more forgiving. Yup. One day that might be a reality. If all goes well, probably by the end of this century.
