I know argon is inert but I assumed that it was needed to keep oxygen away from the reaction; turns out that's wrong, and the UV or high temperatures is enough. That's what I get for not being skeptical about chemistry advice from a guy who poisoned the living poo poo out of himself.

How about horrible electrical failures? Took me 2 hours to figure out what the gently caress was going on, and that was after my friend replaced the cam positioning sensors, starter, and crank positioning sensor. It's a Nissan VQ30DE if anybody wants to figure out what that is and what it's caused by. Symptoms: Car refused to start. The RPM gauge would freak out while trying to start, and the car would backfire and sputter sometimes. Good luck!

Complete opposite end of the spectrum vehicle, but when I had it, my 1978 Ford Escort has a similar problem, tacho going haywire, sounded as though I had dropped a cylinder, but it was my alternator that was shot. Replaced it and everything was fine. I know it's completely different, but couldn't hurt to check?

heat posted:Did you read the part of the article where he was welding with it? It won't decompose into phosgene without argon. and if you use non chlorinated brakleen, it's impossible for it to decompose into phosgene since it only contains pure hydrocarbons (with the exception of the single oxy in acetone, but you're adding a significant quantity of oxygen at some point anyways.) All it can do is flash some fire at you to warn you that you should have been smart and waited a little longer before striking an arc.

I know, I was just pointing out that the word is Sine, not Sign Here's some intentional horrible mechanical failures though. An implosion similar to this set the SuperK experiment back 5 years when it caused a chain reaction of implosions, that wound up destroying 6,600 of the PMTs (each one costs about 3 grand). http://www.youtube.com/watch?v=xBDT47polxo&feature=related http://www.youtube.com/watch?v=C5NO_t9crBE&feature=related

I know it's just another catastrophic engine failure, but I have some personal involvement in this one. This is the remains of a BMW 318 motor out of a very quick car that decided it didn't want to live anymore at the last race weekend of the year. Popped at about 8k going down the back strait, but made zero noise. The driver thought it was a driveline failure, so he didn't pull off. I don't know how much oil this particular motor requires, but I do know that every drop of it was atomized on the line for the better part of 500 meters of racetrack at a width of 3-5 feet wide. So I'm up in the tower doing race control, I hear the corner mention that said car has experienced a mechanical failure and was slowing with smoke. Waived white and surface flags out! He was leading on the 3rd lap of the first race after lunch, and when the 2nd car had arrived at the turn, the 2nd car simply shot off the road. Waved yellow! At this point it was quite obvious that there was a severe amount of something bad on the track so we shut things down. Luckily the car that went off was the only car and he didn't actually hit anything - which was nice. Stoppage lasted 1h 45min with every available body pouring and scrubbing concrete dust on the oil "patch" (we don't use kitty litter for huge calamities like this because it absorbs like poo poo and takes forever... real expensive stuff is apparently around but we're poor) Where the madness started. The fun things you can do as a corner worker at a race track! We found most of the oil pan all over the place too. The owner still doesn't know exactly what caused it, but the whole bottom end is hosed.

Best case scenario - aluminum four-cylinder block? How much would that weigh? And yeah, accurately doing all of this just theoretically would be almost impossible. I can't imagine the first block landed where it was supposed to.

Overhand is great for speed, but is going to put way more stress on the throwing and catching bot than an underhand lob. Also much more difficult telemetry...

I have to imagine that the real reason they did the inspection is because the guy had reprogrammed the thing to lob them a few feet to bypass a broken conveyor belt and half of them ended up getting sent back into the furnace, costing the company 10 times the cost of repair in lost revenue. This story is just so typical of the Randian misguided ideals, how if they'd just give the everyman the chance everything would not only work fine, it'd work better because he was the secret ubermensch. All of that unrealized potential in a forklift driver, because every Randian Libertarian dreams of how they'd reinvent the world if someone would just notice that their burger flipping technique might drop one out of 10 but it's totally 8% more efficient!

I've trained auto-palletisers & it's a right dick to accurately place something at teach speed, the mathematics required to program any throw or catch movements would be beyond the controllers for sure. Timing the catch to a thrown engine block would be hilarious to watch from behind armour because if the first catch wasn't perfect the robot would be shrapnel.
