He literally is making a graphite edm machine and could actually severely hurt himself if he was running more then 10 amps through those big chunks of graphite. It's not something he should be loving with and it's a known science with tons of danger.

So if you do this, do you just walk off the job and never come back? That looks expensive.

Helpful hint: If you find something odd in the pool, don't touch it, and surface immediately. A diver found a broken off piece of a fuel rod holder, and put it in his hip pouch, and only barely avoiding self sterilizing and losing his hand.

There's a guy in my city that's been making a spectacle of his house for decades. Old guy, incandescent devotee. Refuses to put a single led bulb up, and lights his house up enough to be seen by the ISS. He does it up right though, an outdoor shed entirely devoted to breaker boxes and relays and whatever other poo poo an electrical engineer would consider important.

I've asked him what his electricity bill is like but he just smiles demurely.

It's annoying that manure lagoons are still an issue when we have the means to make them relatively safe and produce Methane at the same time that can be used to provide power at best, or safely flared off at worst.

worth noting that the rates of youth violence have almost perfectly tracked the utilization of of leaded gasoline with a 15-year lag. the phaseout started in the mid-70s and by 1990 youth violence was on the decline, contrary to all predictions at the time. it's now at a historic (post-ww2) low and so is airborne lead concentration.

cops a re already murderous psychopaths, of course, but the lead exposure probably doesn't help

For real? Not just some correlation, but showing a real link?

Yes, there’s a study that found data so granular that they were able to track when individual gas stations switched to unleaded and link it to neighbourhood crime rate declines.

Didn't stop them from using lead pipes, lead cups, lead cooking pots, and white lead face paint

quote:

Various writers in ancient Rome considered lead to be a poison, either explicitly or implicitly, including Pliny the Elder, Dioscurides, Galen, Celsus and Vitruvius (80–70 BCE); it was Vitruvius who described lead plumbing specifically to be unhealthy.[6] The epidemics of saturnine colic (17th century) and Devonshire colic both lasted for decades, the latter of which was only recognized by George Baker in 1767 as being caused by lead ingestion some 70 years after it was first recognized as a disease.[7] Lead use and concomitant poisoning of lead workers increased mark Industrial Revolution.[7] The toxic effects of lead in workers were recognized by science in the 19th century, and the first laws regulating lead exposure in the workplace came about in the UK in the 1870s-1880s.[7] The first documented poisoning from lead paint ingestion was in 1914

More EPA than OSHA but:

Not great, not terrible, until you think about the fact that back then "dump it in the ground" was literally the way to dispose of whatever you had back then, not just used motor oil. So you have the ground thoughtfully absorbing benzene up in Love Canal, PCBs in the mud at the bottom of the Hudson River, Perc and TCE in Woburn, MA, god-knows-what in Tom's River, NJ (and also actually a lot of other sites in NJ) and Cleveland* and countless other places.

Oh, and radioactive sludge in Hanford, WA. Who knew that that could cause a problem? Just dump it in a hole in the ground, it'll be fine.

*Cuyahoga National Park is lovely and right outside Cleveland and also the only National Park to contain a Superfund site!

We had a radiological canister show up in the hospital rehab-gym once, some transport person left it in the pocket on the back of this wheel chair...so the tech pulls this thing out, is like "what is this???", and it's like a tungsten tube with radioactive hazard symbols on it...I'm like "DROP AND RUN!" and I get really freaked out, trying to argue with people to leave the gym right loving now. Turns out it was whatever they use to house dyes for nuclear stress tests or something...then the tech went ahead and cracked it open and it was empty. I had just read that story from Brazil about those dudes taking apart that chemo machine and I freaked the hell out (thanks chemistry thread).


kinda similar to this but longer and narrower, scared the hell out of me.

In other news their cybercrimes division just got new computers and can't find anyone willing to take and destroy their old hard drives.

Older diesels with mechanically controlled fuel injection will often smoke a bit to a moderate amount under load, especially if they've been tuned for performance, just because of the limited adjustability of their controls.

That covers GM and Ford up to the early '90s and Dodge up to the late '90s.

Anything modern with computer controlled fuel injection should rarely ever smoke under normal conditions. Maybe a bit when cold, but black smoke from a diesel is unburned fuel going right out the exhaust pipe. The big clouds don't happen unless you're using way too much fuel, and on a modern truck the only excuse for that is a full dyno queen tune that's only useful to make a number.

Anyone driving a diesel pickup truck less than 20 years old that smokes noticeably under normal conditions is almost certainly doing it intentionally.
