Given that this thread is over 100 pages it's probably already been brought up, but the OP mentioning the rocket-salvo interceptor strategy from the 1950s reminded me of the amusing/terrifying anecdote of Battle of Palmdale. There's a lot more general airplane chat in this AI thread too http://forums.somethingawful.com/showthread.php?threadid=3276654 , including a bunch of pictures from n. korea on the last couple of pages and some very nice zeppelin chat.

StandardVC10 posted:There's a company up by Mojave, Orbital Sciences, that launched Pegasus XL rockets, potentially into orbit, from underneath a Lockheed L-1011 airliner. I'm not sure how much launching they actually do these days, or the specifics of their setup, but they have gotten some work over the years. Just to be clear, Orbital Sciences and their Pegasus rocket don't get used because it's cheap. It gets used because launching from a fixed, land based launch point means you have a clear set of flight paths you can launch into without crossing over populated areas, so you have some limitations on which directions you can launch. Flying out over the middle of the Pacific means you have a lot more freedom with launch vectors, so it mostly get used for specialized research sats where the increase in launch cost (versus piggybacking on a full size rocket) is outweighed by the increased performance provided by such an orbit. Pegasus also isn't big at all, either, but it is a cool, niche system. They're working on a bigger model though.

Red Crown posted:If anyone's as interested in the theory behind this as I am, it's theoretically possible. It'd just take three 1KM wide detector arrays 4KM below sea level. Not impossible today (there's a civilian detector 2.5KM below) but probably impossible in the 80s. Theoretically possible in the sense that you could build a particle accelerator with a radius similar to pluto's orbit to do some kicking rad science. I was going to write up a pretty post about neutrino physics but then I realized that I'm both had a bit too much bourbon to do math and that all my experience has been with accelerator experiments and not reactors. That said, what you're describing is literally something out of Star Trek. The Daya Bay experiment (among others) has detectors setup near reactors to do some fancy physics, so let me cite some numbers from them. First, if you're about 500 meters away from one of the biggest complexes of reactors in the world, with some good solid shielded detectors (and by that I mean you have a water tank outside of your real detector to act as a veto against cosmic rays) you're looking at 6-700 events on a good day. Move 2km away from that same complex, and your rates drops to 75 events a day. Move much farther away from that and you quickly hit the point where no one bothers putting a detector because you can't do useful physics with it. And that's with 5 GW of reactor power! A typhoon class sub has about 400 MW of power, so you might as well cut all those numbers above by a factor of 10 already. So yes, in theory you could detector a nuclear sub driving by your array, but really only if it happened to drive within a km of your detector for a useful amount of time, you're not triangulating poo poo from across the atlantic. And don't even get me started on how lovely running something like that in the ocean is, the PMTs experiments like ANTARES use are sensitive to single photons of light, so if you really wanted to defeat them all you'd have to do is maybe throw a glow stick by them and it would be blind as gently caress. Not that arrays like that have very good position resolution anyways, they just aren't designed for it. They're more of a "well did it come through the earth or not" level of accuracy. So it's not just a wall of text here's a diagram of the IceCube experiment, which has a few thousand PMTs buried in the ice at the South Pole. It takes a lot of detector to see neutrinos! e. Not to mention all the work that goes into analysing data to understand what you're actually seeing! By the time you figure anything out the sub you just detected will be back in port!

Arglebargle III posted:Yeaaaah neutrino detectors are huge and heavy. Yup, each of the Daya Bay detectors is 20 tonnes of special scintillator. IceCube is a several km^3 block of ice, Super-K is 50 kilotons of water, LBNE (which is going to have a dedicated beam of neutrinos fired at it) was close to being 200 kilotons of water a mile underground, and now is likely going to be 34 kilotons of liquid argon. I forget how big antares is because honestly, it's just not as good of an option as any of the other detectors above. HyperK, if it happens, might be 300 kilotons worth of water (probably doped with gadolinium to make it more effective). Here's super-k, for scale. E. each of the shiny golden orbs in that picture is a photomultiplier tube, basically a special type of vacuum tube that can amplify light by a million times so that we can see stuff on the individual photon level. They cost 3 grand a pop for ones that size, and at one point in SuperK's history one of them imploded, causing a chain reaction which detonated about 6000 of them. Even if you had an array of these things out there they'd be soooo easy to gently caress with it's not funny. Dr. Despair fucked around with this message at 05:06 on Aug 28, 2014 |

Any proposal that involves the phrase "I will imagine the possibility" is not,in any way shape or form, feasible. At least the dude ends with the phrase "But if this is all nonsense the blame is mine alone" after his acknowledgements. e. The real joke is any sort of proposal for a project that costs more than 1 billion dollars. That poo poo hasn't happened since they killed the SSC, even LBNE is only over a billion right now because of foreign investment.

DakianDelomast posted:I had a snarky nuke joke about 95% being a bomb but after some research you're correct. The problem with a 95% reactor is that if you yank the rods out like what happened with the Russians instead of a steam excursion you get an atom bomb which is a drat slight worse. 20% is a more operator friendly enrichment but results in a much larger reactor size. My guess is that the American reactors have a tighter set of controls on them. I am civil nuke though not navy nuke so it is only a guess. Calling it an atom bomb (instead of just saying prompt critical) is a pretty lovely way to describe it. Unless you're trying to scare people or something. And even then a prompt critical reactor generally results in a steam explosion destroying things (chernobyl, sl-1), and not an atomic bomb style explosion (see: no reactor ever). That said, even if you yank the rods out of a highly enriched reactor that isn't water cooled you don't get an atom bomb style explosion. A good blast, to be fair, but nothing like a nuke going off. This is KIWI-TNT (Transient Neutron Test... good acronym for the test though). It was a nuclear rocket engine using highly enriched uranium, and they pulled the rods out completely to see what the worst case scenario would be. Not sure it's any worse than a steam explosion to be honest... superheated steam has a poo poo load of energy, especially under pressure. e. mostly I just wanted to remind people that we've successfully blown up working nuclear rocket engines... that were designed in the 50's.

DakianDelomast posted:I am not starting a shitfit about a hypothetical reactor that doesn't exist and I am not insinuating that US Navy reactors are unsafe or floating bombs. No, you aren't. That's like saying a dry ice "bomb" is similar to a hand grenade that uses high explosive. Just because it's a bad critically event, doesn't mean it's the same as a nuclear bomb, and there's no way your reactor is going to melt down fast enough that you get a bomb scale reaction before it tears itself apart (that's half the trouble with bombs... making things happen fast enough to get as many reactions as possible before it tears itself apart).

That Works posted:Probably, but I think that it and Fusion power are one of those things that's perpetually "going to be ready in 20 years". The difference between a thorium reactor and a fusion reactor is that the technology to operate a molten salt thorium reactor was tested and shown to work back in the 60's, and the Aircraft Reactor Experiment in the 50's operated liquid salt reactors as well. We're still in the "try and find a way to make fusion actually work" stage and will probably be there for a long time.

Propagandalf posted:Unless they show it next to a pile of enriched uranium big enough to fill that sphere, that's about as threatening as a rolled up newspaper. well you wouldn't want a solid sphere that big (unless you want everyone in the room to die as it goes critical), the trick is to have a hollow sphere that stable and boring but gets compressed into something more interesting when the explosives fire. Looks to me like it could be a mockup or something with all but one of the explosive modules removed, but I can't really comment on if the scale is really feasible (it's certainly much smaller than the gadget was).
