Out-of-control EV blaze (thermal runaway) threatens to sink massive RORO ship.

In terms of actual fires, yes, you're right, water is the best method of controlling them, but as you said, it sucks! I've actually been a member of the fire brigade for quite some time and this is straight from our standard operating procedures concerning lithium battery fires attached to motor vehicles or PV arrays (edited for brevity):

If a BESS is involved in fire, thermal runaway may occur. Thermal runaway is a chemical reaction where a cell fails inside a battery and a short circuit ignites the electrolyte, releasing excessive heat, toxic gases, and flammable vapours. The heat may affect surrounding cells also sending them into thermal runaway.

Cooling with water can potentially prevent thermal runaway. Water is the best extinguishing agent as foam does not assist in cooling and may inhibit use of a thermal imaging camera (TIC) to identify affected areas of the battery.

A large and sustained supply of water may be required (at least 4000 litres). The battery needs to be cooled for 15 minutes, then checked with a thermal imaging camera. After ambient temperature is reached, the battery needs to be monitored for up to 60 minutes, then checked again. In the instance of a large scale BESS – for example inside an industrial building or on a large-scale outdoor installation – there may potentially be multiple appliances required to effectively extinguish a fire and cool the BESS. Ensure that rapid scale-up (with appropriate command and control) is considered. Depending on BESS construction and available resources, a defensive strategy may be adopted, protecting exposures as the BESS burns itself out.


(BESS = Battery Electrical Storage Systems in Government speak)

I'm not suggesting the firies are the experts in electrical components, but I'm sure they would have done plenty of testing and research before they released this advice.

Maybe I don't either.  What's an AFR?

Sorry, I have no idea what you are talking about.

if you don't make soy faces on thumbnails the algorythm will crush you

Sorry, I have no idea what you are talking about, "thumbnail-face" or "soy faces".   I have to assume you are making some sort of joke.  I'm not laughing.

BBC News - Ameland rescue: Crew jump off ship ablaze with cargo of 3,000 cars
https://www.bbc.co.uk/news/world-europe-66310280

Yesterday it was reported by the coastguard the fire was believed to have started with an electric car. But reading the article now that has been watered down. So the YT chap was just a bit quick to jump on the EV cars are bad band wagon for some views.

It's a colloquialism for the overly-forced and fake expressions people pull on video thumbnails. It's the visual equivalent of click-bait... Like "OMG... He did WHAT?!...."
