Wood probably.
Unless you can make all the equipment furniture decoration etc inside free from flammables.
By the time fire reaches the structural elements I doubt the resistance to burning of steel beams is going to mean the building can be repaired Vs rebuilt.
And that's where most EVs mostly charge.
They have roofs, and we charge partly off ours.
It is a lot cheaper than building an oil well, a refinery, pipelines, and a fleet of tankers by sea and road to provide a network for refilling cars with dangerous flammable fluids.
One day, every town will have a petrol station.
And a while later,
not every town will have a petrol station.
Have you seen a new petrol station recently?
You think, or are paid to repeat, that an equilibrium is a magically fixed point, and that the addition for instance of cargo to a ship which is floating with its weight in EQUILIBRIUM with the upthrust from the water it's hull has displaced, will not cause it to find a new equilibrium, a bit deeper, thus with more water displaced, and more upthrust providing an equal and opposite force to the increased weight.
At some point adding more cargo etc causes this situation to change, suddenly, and catastrophically. There's a line on the ship, named after Plimsoll.
It's quite a good analogy, but all analogies are moderately bad.
I'm sitting in my chair. Mundane, but a technology of work with some persistence so far.
I'd like a terminal in the top left screen, Gimp on the bottom right, Firefox windows on left lower and right lower.
And a text editor, just where it was last time.
Am I being unreasonable?
Oh, and I do like to run an X session from the other box, otherwise I get confused about mouse, keyboard, screen.
And selection doesn't need to be natural, or left to nature.
Whether you see the memes around antivaxism* as faulty or a competitive cognitive organism, that's where the need to remove, suppress, or patch is nowadays.
More Dawkins than his predecessor Darwin.
* etc
unless they have electric cars in?
If a car in the cargo has seawater washing inside its battery box and getting into the modules, I venture to suggest the ship already has a very large problem.
Different fires will have different characteristics, but the peak output of a burning car is similar, at 2-6MW, regardless of it's motive power, since it comes from the fittings, in the main.
An interesting difference is the burning petroleum that runs out of one sort, and spreads under other vehicles, and downhill if it isn't prevented. That's a hard fire to control.
Some provenance on the rumour or suggestion would be useful.
Not how the batteries are built or installed.
A marginally plausible approach if the battery swap method* of quick recharging caught on would be to ship them separately, but the batteries are going to be interesting cargo containers.
As would be loading.
The state of charge could be kept low, say 50%, but they are probably made and tested at over 80%, so that'd be quite a faff.
* Works well for scooters, with I gather 2 battery slots, and perhaps a convenient weight for hand-carrying.
For cars or trucks you pull up and a robot whips out your partly discharged leased battery, and inserts a charged one. Rather quicker than a tank of petrol, I gather. Not popular though.
It is a bit informative.
Also a bit misinformation.
But first, you are not generally being asked to buy operate or use an EV. You are however being asked to stop using ICEVs, not all at once, but soonish, in order for the planetary ecology to survive in forms useful to us.
The UK Grid: total power demand is still well below its peak of some decades ago, so we are not going to overtax it;
BEVS predominantly charged overnight, when there is lots, and sometimes excess, of capacity. Not a problem (or rather a collection of problems easily solved over reasonable time).
Super gadget for taking one burning car out of a parking structure. Perhaps it could have taken the burning ICEV out of the airport park recently? Before there was running burning petrol from the others, which as with the Liverpool structure fire was a mechanism of spread, and I'd think a difficult environment for a robot.
The establishment the fire brigades use for research compared burning ICEVs and EVs.
They measured similar power outputs from each, peaking as I recall at 6MW
That's on of the two methods of lighting more cars.
The other is burning liquid fuel running downhill.
As to the logic of "the deck contained* EVs therefore the fire came from an EV", I hope the poster is not a programmer. A cause remains to be established.
* I noticed the report didn't say "only".
Kettles:
The most obvious thing is if you want two mugs of tea (750ml) then put 760ml in the kettle. Remarkable how much the "power" is increased.
(And the external surface area to lose heat from is decreased, opposing a ise in wasted power).
We have some solar panels. Not enough to run a 3kW kettle, but often enough to run a 1.5kW one. That seems to me like a power saving outside the house.
