I'm sure that nothing could go wrong with drivers looking exclusively at a screen that shows them what's 4-6 feet behind them and nothing else  What I can't believe is that GM is expecting to sell self driving cars by the end of 2016. Not that they can't make them, mind you, but that people would trust a car that drives itself from the company that couldn't make sure that your brand new car can stay on while you're driving it

SEKCobra posted:Correct me if I'm wrong, but wouldn't it be easiest to just put some wirecutters to the brakeline? I think that would be too noticeable, who doesn't use their brake until they're going +30? Maybe a couple holes in the top of the lines so the driver can get a couple stops in before there's a problem, but I think brakes cut are more of a movie thing since they can contrive a reason that the driver wouldn't brake until they're going fast

Sir_Substance posted:I'm not an expert, but I gather it's variable. Depends on the mechanism and how much power you put through it. Bingo, the material/positioning of the wick, the airflow into the atomizer, the width of the tubes, voltage of the battery and resistance of the coil all contribute to the thickness/smoothness of the "smoke". The smoke is atomized propylene glycol, vegetable glycerin, flavorings and psychoactive substance of choice There are some people who just like the feeling of smoke and have nothing in their PG/VG solution for whatever incomprehensible reason. Emerging studies show that these produce worrying amounts of formaldehyde out of the PG and VG at those temperatures, dubious studies aside, we really don't know the long term effects of them are besides, "gently caress ton safer than real cigarettes" but likely not great for you EKDS5k posted:Don't forget there is some kind of plastic manifold for coolant in there, which will crack for no reason at all.

ShittyPostmakerPro posted:Am I the only one who doesn't notice any threat from these tire blisters? If the tire is stable and stationary, it's doubtful that the rubber will rupture, especially if the pressure is released from the valve (infact, the bulge would be the first thing to deflate). Even if it does burst, the tyre itself will not blow out, so provided you're not within the bulges diameter, you're not even at risk of being hit by the flapping rubber. It is likely pretty safe to deflate, especially with all of the damage pointed away from the nozzle, but all I can think of when I see that is the gif of that Chinese guy who slashes a truck tire and it blows him off his feet, his shirt off and the knife across his forearm

Jeeze, it was 4°C colder than that here last week and even though shifting was really clunky and felt awful, my Honda started and drove just fine in -11°F. What the hell do they put in their transmission that's so thick? I don't know if this counts as a mechanical failure since it's electrical, but Ford decided to have the wiring on their focus hatchbacks make a weird twist at the hatch joint so that it rubs and eventually destroys itself as you use the trunk

Buy an old garage with the pit in the floor for car maintenance, put in a regular old lawn sprinkler, a fan, a way for the water to drain and there you go.

Enourmo posted:I'm pretty sure chlorine trifluoride will oxidize oxygen itself. John Drury Clark, the guy who literally wrote the book on liquid rocket fuel posted:It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water — with which it reacts explosively. It can be kept in some of the ordinary structural metals — steel, copper, aluminum, etc. — because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.  Apparently it will actively burn sand, CO2, water, and Halon, so there is no known way to suppress a ClF3 fire

I think the operating temperature of tires on the road would be high enough to be legit dangerous with hydrogen, but not too much worse than magnesium rims without a direct source of oxygen or other oxidizing agent. Actually, speaking of alloys, I'm pretty sure that steel becomes incredibly brittle when exposed to hydrogen

Platystemon posted:Hydrogen permeates through vulcanised rubber five times as fast as air, and probably at a greater ratio between the tyre and the rim. And through steel, aluminum, and even titanium. I was remembering AP Chem correctly after all https://en.wikipedia.org/wiki/Hydrogen_embrittlement posted:During hydrogen embrittlement, hydrogen is introduced to the surface of a metal and individual hydrogen atoms diffuse through the metal. Because the solubility of hydrogen increases at higher temperatures, raising the temperature can increase the diffusion of hydrogen. When assisted by a concentration gradient where there is significantly more hydrogen outside the metal than inside, hydrogen diffusion can occur even at lower temperatures. These individual hydrogen atoms within the metal gradually recombine to form hydrogen molecules, creating pressure from within the metal. This pressure can increase to levels where the metal has reduced ductility, toughness, and tensile strength, up to the point where it cracks open (hydrogen-induced cracking, or HIC). Though hydrogen atoms embrittle a variety of substances, including steel, aluminium(at high temperatures only), and titanium, hydrogen embrittlement of high-strength steel is of the most importance I'm pretty confident in saying that helium would be similar in its ability to permeate everything. I know MRI machines have had problems with their liquid helium escaping through the metal it's sealed in. Speaking of MRI's and spectacular failure, back when I worked in a hospital, we had a guy bring a steel oxygen tank on a cart into the MRI room. It flew 15 feet into the machine and caused $1.3m in damages and lost revenue because he didn't know what all of the giant, red signs and flashing lights meant

Platystemon posted:Once, for the PYF Dangerous Chemicals thread, I did the calculations for the power emitted by a 2‐litre bottle filled with radon. I was just thinking about polonium's obnoxious radiation emissions, that scary RadonTM fad when it was discovered, and the fact that even the most stable form of radon has a half-life of ~4 days, but I suppose just plain old radon would still put out enough energy to melt the car to the pavement... Polonium though, polonium is insane. It was used to keep Soviet computers from freezing up in the vacuum of space because of every gram of it produces more than 100 watts and undisturbed polonium will reach temperatueres close to 1000 degrees if there's more than half a gram present. I had always thought that alpha radiation was generally pretty harmless to humans because light clothing and having skin will stop it from damaging your DNA, but polonium produces enough heat during decomposition to melt it and allow it to diffuse through latex gloves, through the skin, and into soft, unshielded tissues, where it is a massive loving problem. For whatever reason, being in people accelerates its rate of decomposition and it takes less than 1 tenth of a microgram entering the bloodstream to be lethal. I was going to ask why it never really got used for anything noteworthy, but I answered my own question. E: Geirskogul posted:How good is a water trap or water draining on an air compressor? In theory, they're great, 120psi should make water become a liquid inside of the compressor and then removing the condensed liquid shouldn't be too difficult, but gasses were never my strong suit, so I'm not completely sure. If looked up the triple point chart and did some algebra, I could give a less half assed answer, but it's 2am so
