let's talk a little bit about ion implant and how electrostatics work and how they both like and hate each other -in order to accelerate a particle you have to run it through an electric field - since fab space is expensive, the optimal implanter is infinitely small, which means that your field is infinitely big -in general, electric fields break down in air somewhere between like 50 kV and 75kV per inch and something like 30 kV/in along a surface so, we have a problem! you can't go much beyond this or you'll just create loving lightning when the electric field breaks down, but you can't go less than this or the machine will be too big what's an engineer to do? if you thought, "gently caress it, just let the lightning happen and deal with it", you're right, that's exactly what they do! the only downside to this, other than creating actual loving lightning, is that if you let too much lightning happen you'll actually blow up insulators and resistors and tranZorbs and other poo poo, so what does the reliability engineer do? why, they set the system up and monitor how often it arcs and creates lightning by measuring the number of light flashes and thunderclaps per hour over a year or so! this system was about a meter away from the system on which i worked on right out of college... on the high voltage system... while having a gigantic loving lightning strike behind me arcing audibly every couple minutes or so it doesn't matter how many times you've checked your lockout tagout, when you have your hands in an acceleration lens and you hear a thundercrack, you loving jump every goddamned time

For example, even though hydrogen is highly flammable, but since we are doing 80 percent H2 and 20 percent CO2, the mixed gas is actually outside the combustible range and are safer to use.

when i say lightning, this particular terminal was riding at 400kV, and i think the capacitance was something on the order of a couple hundred nF; let's assume total breakdown 1/2 c v^2 = .5 x 200 E-9 x 4E5 x 4E5 = .5 x 200 x 4 x 4 x E-9 x E10 = 100 x 16 x E1 = 16kJ that's a lot of energy to release in one short go, but also isn't a whole lot of energy at the end of the day, so the ozone production was basically nonexistent

OSHA thread, I have a question. Let's say there's a hill, 200 yards wide by 300 yards long. The middle rises to a 60' mound, we can assume a uniform shape, roughly triangular pyramidal in design. How long would it take an average construction team with modern equipment to excavate that area, to a depth of 60'? Edit- For context, there's 5,400,000 ft of earth to be excavated down to ground level, then an additional 32,400,000 below that. Ground condition is sloped and marshy, with a series of large stones on the top of the hill and around one edge of the field. PHIZ KALIFA fucked around with this message at 16:33 on Jan 8, 2020 |

so, okay, there's one perhaps small detail which should be mentioned. in addition to the ground conditions being soggy, there's a slight chance that underneath the mound there's a, what do you call it, tomb. slight chance of tomb. i don't know what the digsafe code for that is, but let's just imagine this is an area with no labor laws nor conservation of antiquities. maybe these crews are even paid extra to gently caress up the tomb, just for spite. maybe. so at least some of those sq ft of space will be occupied by "tomb" rather than "wet dirt." however that impacts calculations.

and, before you ask? it's a normal tomb. nothing creepy or bad or horror related about it at all. just a nice, safe, normal tomb, without any wandering monsters at all. edit- yup just tryin to get some quotes for remodeling my summer vacation tomb that's all. no reason to investigate this much at all.

Depending on where you live there are laws about disturbing burial places. If there's any chance that it's historically significant, you'll want a team of archeologists to look it over as well. Do everything on the up-and-up with legitimate contractors and they should be able to walk you through the proper practices. Don't be an rear end in a top hat about it.

Are we talking modern excavation techniques or maybe something more like, oh, faux-medieval fantasy tech? Is your crew going to be using picks and shovels? This could take months or years if so, depending on the size of your crew. Do you have access to anything like Stone to Mud or Earthshape or similar?

It's not uncommon for excavators to find unmarked graves- you just need to know that if the police/city are called your project will be put on hold for a long time. Depending on the crew you work with they will usually make it go away before involving the authorities, but be prepared to grease the wheels if you have to- pay in cash if possible.

The reason I know this is that our house marker is a recycled gravestone from the 1930s- when we were building the town inspector saw it and mentioned the amount of graves in the area that he's seen get churned up during construction projects, and the complications of involving certain authorities vs just reburying somewhere else.

If your tomb just happened to have a Sphere of Annihilation near the mouth, a bulldozer could get a shitload of work done. Just don't tell OSHA, the safety regs on SoA's are just the worst

Thank you both for your concern, but I promise both of you that any bodies discovered here are unmissed and under NO jurisdiction, either Man or G-d. This is not a place of honor. Nothing of value is buried here. Bad Munki posted:You say tomb, but what are the odds of, say, a dungeon? Any chance of a dragon? Dungeon? No, this is a tomb, that means it falls under Tomb Raider Union rules, local 36DD. Also, zero chance of a dragon. Minor possibility of lich infestation. Very minor. Nothing to worry about. The technology available to the crew is whatever modern technology we've got. No spells, outside of what is encountered in the process of disassembling the place.

(shuffle shuffle) Yes, there does seem to be a disk approx 3' in diameter which destroys all physical matter it comes into contact with. Is that a hazard? Should we mark that off with cones?

I worked as an archaeologist for about a year and if there's a know burial on the site it won't be excavated. In the US at least. Pre excavation, if it's not known, but there's a chance there's a high probability of a burial due to proximity to other significant sites/burials, there will be an intense survey done. If there's been no survey, or previous surveys haven't proven there to be anything significant in the area, there will still be a survey done but at a broader scope. For a strange, pyramid shaped mound or earthwork that is untouched, you sure as poo poo won't be digging your giant hole for years, because I promise you that archaeological survey will take years to complete, and then years to study and publish. Also if you want to do the math, I could dig a 1m x 50cm x 50cm hole in about 10 minutes in my prime. Apply that to your total volume of dirt and that's about how long it would take me to do by hand.

Like, just dig the whole thing dude, it doesn't have to be made up of perfect squares.
