A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

Speaking of fire trucks has anyone here ever read the emergency response procedures for teslas in severe accidents? When I was a volunteer we gave it a look over.
If I remember right, Depending on the model they recommend up to 8,000 gallons (~30k liters) to keep an overheating battery's temp stable in case of fire or exposure to high heat. I'll link the resource page here.
Our engine holds 700 gallons (5.2k liters) and the typical tanker in our area holds 2,000 (7.5k liters)
That's a house fire level response for a single electric vehicle. Just getting that much water moved to a scene would be challenging. We have tankers, but how many city departments can move that much water? You don't see hydrants on highways. And foam is not effective like it is for normal car fires. The future will be interesting for firefighters.
I found a link on how the Austrian fire workeres handle this. The fire is extinguished first, then the remainders of the car are put into a special roll-off container (Abrollbehälter, AB) and driven to a gravel pit, where the container will be flooded with 21000 litres of water.

That's interesting. Tesla says the cars shouldn't be submerged but I wonder if there's any serious consequence if you did?
After this procedure, the car is irreparably damaged, if this was your question.
As far as safety. It is a big battery after all
30,000 liters is 30m^3, which is a back yard swimming pool full of water.
Now imagine a house on fire with a tesla in the garage or multiple vehicle accidents. Now you need that much more
Now imagine having to use 30,000 litres of water for every Tesla/EV on fire while facing extreme drought conditions caused by global warming.
lookin at you Cali
