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.

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.
This doesn't I think stop adverts actually written into the page, with images if necessary, served from the server that delivers the page.
Which I find less objectionable, and also probably quicker.
And available for inspection by the page owner.
When the Web was mostly HTTP I made some use of the Squid proxy, which allowed analysis of the page, and replacement of some material with a short text: advert, or occasionally vile advert.
But building Squid with HTTPS and being Squid-in-the-middle is a step I've not taken, and I think neither have the distros.
Hot salt isn't best charged photovoltaically - you could but it seems a bad idea - but by focussing sunshine on a tower.
So not great for Scotland.
Then it returns heat through the night which makes steam for your turbine, or hot water for your heat pumps.
Flow batteries OTOH look interesting.
There are no dunkelflauts for tides, nor do they wait for any man.
The tidal barrage across the Rance estuary paid for itself a while ago, and turns out a predictable pattern of power. For decades past and to come.
Having something like that, even if it isn't the whole of the Severn or Bristol Channel, is quite attractive. Given a couple of adjacent lagoons one could get clever with continuous power.
For very low values of "often".
The likelihood of a fire is going to rise with the number of cabinets, but also with the number of installations.
The likelihood of someone bring there ready to do something will be high for a huge installation, and low for a small one.
I suspect arithmetic has been done.
Using electricity to dry the air seems to be no less effective than using it to heat a tumble dryer.
And the power used is delivered inside the house, with an efficiency rather over 100% because the energy of condensation comes out as well, and the dried air is cheaper to warm to room temp than damper air - water has a high specific heat.
It gets complicated.
Scotland is connected to England, Wales, and the Irish Grid.
And windy.
So sometimes the connections, plus all the kettles in Scotland, are maxed out and wind has to be discarded.
Batteries near the generators allow more electricity to be captured, and it's release to be spread over longer periods.
Part of it is degree of readiness.
If you need a thermal power station to deliver 4GW at a moment's notice it needs to be turning and burning.
With a day's notice it may not even need the pilot light on.
With a week's notice you could announce an unscheduled Bank Holiday.
