EvilJoven posted:I wanna know what happens if it gets in a crash. Do the passengers get exploded, burned, or boiled to death? None of those. The system mainly contains wood pellets, which aren't very flammable, and small amount of carbon monoxide. Wood gas operates by burning wood in a low-oxygen container producing carbon monoxide. The CO is then piped to the engine to use as fuel. Since the CO is being produced constantly there is no need for a large pressurized tank. https://en.wikipedia.org/wiki/Wood_gas Biggest danger in crash is probably getting crushed by the equipment.

Nebakenezzer posted:I get why a short circuit in large batteries is pretty much a nightmare scenario...how does a badly patched hole contribute to this? Also, ahhhh, wtf they were patching damaged batteries and their patch didn't even stop the loss of electrolyte?! The patch does nothing to repair the damage in the cell itself. There is a membrane inside keeping the electrodes from touching and let the chemistry do its thing. If you puncture the cell and it doesn't short-circuit, getting warm might deform the layers enough to do the job. You don't want oxygen in your cells, since that degrades the cell, lowering its capacity and raising it resistance, making it run hot easier. Losing electrolyte also means a degraded cell and electrolytes are good conductors and often corrosive. Lurking Haro fucked around with this message at 23:18 on Aug 1, 2018 |

Lithium cells of the sort Tesla uses start with a long sandwich of positive, separator, negative that are rolled up and put in a cylinder:  https://www.youtube.com/watch?v=gYFuVbZmu5M&t=1441s The positive and negative parts are really close to begin with. Poking them with a needle doesn’t improve their separation. Patching them might stop the electrolyte from leaking more than it already has but it doesn’t undo the damage. Further, the patch itself might put pressure on the cell and make the problem worse.

Memento posted:Yeah, so like 3 mpg? Not great. Efficiency rate of the gasifier allow to convert about 75% of fuel energy content into a combustible gas that can be used as fuel for internal combustion engine. As result of practical application of wood gasifier has been found that 1000 kg of wood combustible material could replace 365 litres of petrol during real transportation [2]. That's around 1 pound of wood per mile driven, I have literally no idea how you got 3mpg. gallons of what, wood alcohol?

That’s pretty light for wood, so maybe it assumes a unit of volume like the stère or the cord that encompasses empty spaces within a stack of wood.

Wait how many teslas have these punctured cells? We gonna see Model 3's burst into flame at a regular pace over the next 3 months until Tesla's forced to do a recall, which sinks the company? That'd be rad.

I mean tires are just shoes for vehicles, right? I see no problems here. But yeah, really, what? Is that actually 2 separate wheels or did they jam a tire onto a wheel, a... half tire and some soles? I am really loving confused and interested in that.

Lowe's and some other stores are gonna stop selling NMP and methylene chloride this year. Lowe's in particular said they intend to work with the EPA on implementing some manner if regulatory standard for the industry (DIY retail? Dunno).

I understand Telsa hosed up when they didn't parter with anyone who understood automotive mass production which is in fact really hard. Any automotive manufacturer would have been happy to partner with them - but, this would be bad, because - NUMMI was a Union plant? But this poo poo - how up your own rear end can you get? This behavior is screaming for a nuke it from orbit class action lawsuit. If history wasn't enough, two huge scandals have recently destroyed automotive companies: VW and Takata airbags. One doesn't exist anymore, (haha, it's motto was "quality first" and the other has royally hosed itself in North America - if it comes back at all, it'll take a decade at least. I guess I'm echoing much more pithy comments above, but holy poo poo

I don't think we have yet enough information about this issue. Apparently 1173 battery modules got dented/punctured and 732 of those went into Model 3s. Hopefully they were only dented and didn't have cell damage. The second hand information about the repair method is concerning, possibly enough for regulatory body to issue recall. At which point Tesla needs to prove what happened to the battery modules with damaged cells. But it feels it would be easy to open the modules and replace any damaged cells before using the batteries. Tesla's manufacturing issues have been centered on car manufacturing with multitudes of failings. But I think this is the first issue I have heard about in the battery manufacturing. That is Tesla's specialty and I doubt there were any established car manufacturers they could have asked for help.

Absolutely, they could have. Tesla vastly underestimated the difficulty of mass production; it was sheer arrogance that they didn't subcontract it.

They seem to be standing somewhat down wind of a burning car that is also burning its huge battery, that seems unwise.

Zipperelli. posted:VW were the ones messing with the emissions testing or falsifying results or whatever, weren't they? They deliberately programmed their cars so that when they were being tested for emissions, they changed their programmed tune in order to comply with the tests. Then when the test was over, they went back to their regular tune which had better power and fuel economy but emissions that weren't even close to meeting the standards.
