We are sad about virus and you are sad about batteries.

Stuffing agressive chemical reactants very close together, and for cheap, could be a challenge. GM's global recall sounds expensive. I'm not sad, as long as nobody forces me to buy an electric car. Actually, I'm rarely sad about anything, unless I curdle the bread pudding; that's the main anxiety in my life.

I am more curious than said, as data available from NCBI doesn't really agree with what everybody is saying in news media.

On a sunny day (Wed, 04 Aug 2021 13:09:06 -0700) it happened John Larkin <jlarkin@highland_atwork_technology.com> wrote in <pqslggdiehomu3o5540vh3fml2mtc44rqq@4ax.com>:> >https://www.msn.com/en-us/autos/news/while-they-were-asleep-their-teslas-burned-in-the-garage-it-e2-80-99s-a-risk-many-automakers >-are-taking-seriously/ar-AAMVBlV > >https://www.theguardian.com/australia-news/2021/aug/02/tesla-big-battery-fire-in-victoria-burns-into-day-threeBatteries are always dangerous. I have an old mp3 player, runs on one 1,5 V eneloop battery. Put it in my pocket, wanted to bring it upstairs, something burned in my side, thing was melting! Now eneloops do not catch fire, but I did not expect those 1.5 volts AAA to have that much power! Found the construction had a non-insulated wire to the positive pole all along the side of the battery, Battery insulation (just a piece of plastic foil) had been damaged over time, good short! If if happens with li-ion you would be on fire. Fixed it, new insulated wire, some hot glue, new battery terminal embedded in hot glue... Looks like shit, plastic all deformed by the heat.

Big batteries are lot less dangerous than large chunks of chemical energy. Bulk storage of ammonium nitrate has produced a couple of mega-ton explosions. As usual, the structures that store the energy have to be designed to cope with unexpected energy release, and the engineering isn't always quite as perfect as one would like. The big battery will get rebuilt in a way that will make less likely to blow up in the particular way reported. With any luck the designers will anticipate a bunch of similar problems. It doesn't take too many iterations to make failures very infrequent. -- Bill Sloman, Sydney

It has recently been noted over here that car insurance costs are higher if the car is left in a garage rather than on the drive[1]. Battery fires are likely to exacerbate that. [1]The suspicion is that cars are getting larger (think SUV) and so are a tighter fit into many old garages, with the inevitable scrapes.

Not a chance.yeh, the three biggest are all around 3000ton of ammonium nitrate

Effective chemical fire extinguisher technology has been and continues to be developed to quench large lithium battery fires quickly and efficiency. This should be a legal requirement for any storage battery farm, an automated fire extinguisher, before they are permitted to build the project. Industry wants to skip it because it's expensive, and all they end up doing is hiding the true cost of their project. And don't hold your breath for any residential codes to require an extinguisher system for interior spaces used to park electric cars. These people are notoriously reckless and corrupt too. The idiots seem to think they're still in the 19th to mid 20th century mode of operation. Someone needs to remind them they are not.
