If they are house-bound, organise with a local taxi driver to get to the shop and get some things for them.

If they are mostly-mobile, same thing, but organise a drop off and pickup time and get a hand with getting groceries into the house and up stairs, etc.

A lot of the older "career" drivers will happily do regular stuff like this. Especially during the middle of the day in suburbia when it's pretty quiet. Beats sitting at a taxi rank reading the paper.

What do you expect from running 10 and more amperes through a cord?

Well , I expect enough engineering behind it that the cord and connections don't melt. I am an auto electrician, I routinely deal with 12v systems that draw much more than that without melting, using connections that aren't much bigger. It's not like it's some mystical technology, it's just that this setup has been done on a budget.

But it doesn't help that every single logic gate in a graphics card is run at a speed/currents that are literally just below meltdown.

It's difficult on the back end of the charger as well.

A shopping centre or rest stop can't just spring for a few high capacity chargers for the car park. A single megawatt charger is 50 houses worth of consumption, so they now need a substation upgrade to provide what is basically a whole neighbourhood-equivalent of power.

You've got it all wrong, in traditional computer terminology the "hard drive" is the box that sits under the desk that collects cat fluff and cigarette tar.

There is an empirical way of doing it - best one I've seen online so far is this:

AN186 - Brushless DC (BLDC) Motor Connections

I don't understand it. If I was a politician right now, I would not, under any circumstances, hitch my political wagon to the shitshow that is going on in the US. But Dutton and that "Trumpet of Patriots" crowd - bless their 1950's White Australia hearts - are all for it.

Labor would be wise to stall the election for a month or two, just to let things unfold a bit more over there.

It doesn't have to be "buy local", per se, it just has to be "buy non-US". But there are few tangible things I actually buy from the US. I don't mind stuff from the EU, it's a little pricey due to our exchange rate, but for the things I buy it's generally OK.

There are heaps of services that are bought from the US though - just about every streaming service, Google/Apple, Starlink, and so on. Those can fuck right off , if possible. Sometimes that's not practical (eg google/apple's ecosystem), but at least have a look for alternatives.

They aim to actively deorbit starlink sats.

(Edit: they keep a small amount of propellant in reserve for the initial deorbit burn, and then position the solar array to give maximum drag which hastens things considerably)

As far as I know, apart from the first few batches, the "production run" of sats has a pretty low failure rate and are proactively sent to their demise.

Older engines had them in their timing gears - they were in 6 cylinder Holdens, for example.

They give an amount of cushioning/vibration dampening that you can't get with steel gear sets.

Eight years ago every single booster was lost on every single launch, and now it's, "Oh no, one caught fire!

On the ground,

after an on-target landing,

after a successful payload delivery to orbit,

after four previous launches and successful recoveries of the same booster!

RELIABILITY CONCERNS!"

It's because the two most important metrics of EVs , range + performance, aren't visible.

And - let's be honest here - those metrics are mostly the same across manufacturers due to battery limitations.

So they have to overcompensate with style to stand out from that other EV that uses the same base platform and the same battery chemistry and the same charging system and etc etc.
