Why are the cabbages not on a chute down the middle? They would auto-feed when the previous cabbage falls away. edit: coconuts?

if that coconut machine had a foot pedal it would be safe. and by that i mean it would operate like the gas pedal of a car and get it up to 1000 rpm or whatever for the real pros

Memento posted:I think that's the difference between critical and prompt critical, where you get the blue flash and the incredibly painful death but no boom. The blue flash (from air ionization) is also prompt critical. When you have a fission reaction, some neutrons come flying out of if right away. These are prompt neutrons. More neutrons come flying out of it from subsequent decay of the daughter products, but that takes a while, on the order of some miliseconds to seconds or even minutes. Those are delayed neutrons. This delay is what makes nuclear power plant control feasible: you arrange your reactor such that the reaction is subcritical based on the prompt neutrons, and it's only the delayed neutrons that bring it to criticality and supercriticality. "Prompt critical" means that your reaction is critical based only on the prompt neutrons. For bombs that's what you want, for nuclear reactors it's contraindicated. Methylethylaldehyde posted:Criticality gets you that charming robin's egg blue cherenkov glow, prompt criticality does that, plus violently self-disassembles anything involved with it. You only get Cherenkov radiation when charged particles travel faster than light in a medium. The speed of light in air is close enough to the speed of light in vacuum as makes no difference, the blue glow observed during these criticality incidents is not Cherenkov light. It's just ionization of atmospheric nitrogen. You can get Cherenkov in the atmosphere but it takes particle velocities higher than you get out of nuclear reactions, like cosmic rays or particle accelerators.

LifeSunDeath posted:Trying to think if a massive AN explosion would make AL better or worse. I grew up not far from a major industrial port. There's a reason why the storage depot for fertilizers and other potential explosives (you could tell from the smell even before a field trip from school toured the port) was located outside the port itself in a thinly inhabited area, linked by rail to the rest of the port.

I'm sure that, in 1945, enriched uranium is available in every corner drug store, but, in 2020, it's a bit hard to come by.

Joking aside, it'd be the easiest way to produce a nuclear weapon. It only requires access to enriched uranium, no shaped lenses or abundance of reflectors, nor the need to produce plutonium. Its obviously much easier to get Uranium-235 than Plutonium-239, since its the basic form needed for Nuclear Reactors. Granted, you still need to separate the isotopes with centrifuges, which will require a fairly large industrial footprint.

In reality, the worst that will happen is someone makes a dirty bomb and some city spends millions of dollars vacuuming up radioactive dust.

Cock shaft is a preferred shape but a flared end is getting into the realm of dangerous geometry.

Possibly not quite as fun to experience in person, but still, nifty! "That's so cool!" Said the ludicrously irradiated scientist. Then again, there's a letter that a Frenchman who was stung by a poisonous sea snail in Tahiti wrote as he was dying, describing the pain as "exquisite".

It was so simple that they knew it would work without testing it and requires nothing more than enriched Uranium. A gun-type weapon using U235. If you have the salvaged plutonium core from an old fission bomb, making that into a gun-type bomb is going to be incredibly difficult. That was the whole point behind the implosion type, the rate of spontaneous fission in Pu239 is so high that making a gun-type bomb with it was impractical for the US.

well fortunately you don't need any special technology to get U-235, it's literally just lying around in the ground out there
