It might have a capacitor.

The Challenger, I recall being told, has 30 seconds braking. I inferred that if it then let the brakes cool it would have 30s again, until it needed it's brake pads replaced.

Why do you think a tank wouldn't have electrical braking?

Plausibly worth having just for going downhill, but the bonuses of providing power for the boiling vessel and being alternately a motor along the lines of the Formula 1 car might be appreciated.

I don't know what the clutch life on tanks is, I suppose there's a torque converter, but you might even find a fully electric transmission is useful, as on trains, heavier and faster vehicles running on tracks that they are.

Get clever enough, and you run a combustion unit at its most efficient speed to generate power, making it smaller and quieter.

NHS major 'cyber incident' forces hospitals to use pen and paper

Re: It shouldn't make too much difference.

It isn't clear to me that the library needs to be on the same network as the patient records.

Even if it is being used on the same desk.

(Indeed, working on two screens is probably more effective than one, particularly if the clinical record is designed to use all the screen.)

Ramping seems a widespread problem

Ambulances being held outside hospital doors is widespread enough the Australians talk about the ramping problem.

This may ramp it up a bit though.

Re: The odds of an actual collision would be astronomical

But ... when the spacecraft manoeuvres, why do you think it takes its cloud with it?

You'd have both dodge, so as to avoid each others clouds.

I will say that's the first time I'd heard that theory, and traces of atmosphere, minute differences in orbit, radiation pressure, and possibly earth and solar magnetic fields might be reasons why.

NHS to launch 'real-time surveillance system' to prevent future pandemics

In 1633

we were less sure about what worked and didn't work, and why.

Since then we've learned a few things, well, the fact-based community have.

So yes, we do know what we can do.

Re: 'real-time surveillance system'

You'd need to show some workings there.

Obscure functionaity

A bit like minor surgery = surgery on someone else.

A consequence of Open Source is that if someone wants to add a function, one they want to use, then they cannot be prevented from doing the necessary work to produce it.

I see that as benign.

(It doesn't ensure anyone is capable of the work, or that anyone else incorporates it)

Re: @Doctor Syntax - If Russia gets away with destroying Ukraine :o

I know more history than that.

I'm not so old as to remember the Great Game.

Russia's rulers do not want adjacent countries doing better and having fun, it sets expectations domestically.

Nor, I think, do they want a large reservoir of people able to accomplish the next revolution. The cull continues.

Malicious xz backdoor reveals fragility of open source

Many eyes...

And one found it, and mentioned it.

Whether any found it and stayed quiet, banked it, we don't know. If so, they've been frustrated, also.

Theres a paradox about finding such a fault, attack, crime etc.

Once found and announced, it has been found. It can't be found for the first time again, snd yet we are told that being found only by one person shows a system isn't working.

A moral hazard

Is something different.

This is a hazard.

Is it unique to Open Source? (No).

Is its discovery specially Open Source? (Maybe).

Speed of construction

Aircraft take 1 year.

Re: Things Resembling Locks

Likewise. Different model.

midgepad

The lock is only

to tell people the door is not for casual opening, usually.

If there is no lock, it is hard to reprimand someone for opening the door.

If there is a lock (or other alleged security mechanism) then it is clear to anyone without the key that they need a reason. As indeed he had.

Ford pulls the plug on EV strategy as losses pile up

midgepad

I see above nobody will buy EVs because they are expensive, and i see above that 2nd hand EVs are going to have lost much or all or too much of their value.

Should you talk about that amongst yourselves?

Meanwhile in the last year I have seen one new petrol station in 6000 miles, can think of three that have closed within 50 miles of here, and see charge places popping up like a rash.

You'll be able to make a living selling petroleum, for a while.

midgepad

Energy density and amount

After rather a lot of posts telling us the battery doesn't hold enough energy and is heavy, so low energy density, we have one telling us that if it held more in smaller volume it would be dangerous.

C4/P4/TNT no, but something approaching the density and total energy of 20 - 40 litres of Diesel/Kerosene/RP1 would match or surpass the capacity of standard uk cars (which are mostly not topped up nightly)

20 litres because more than half of a petrol tank is turned into heat - a wastage if you are driving it, and a hazard if containment fails. 40 litres because it takes longer to fill up.

I remember when a megabyte of RAM was a big expense.

Routes round here are electric

I think there are areas of the uk or even England where this hasn't happened yet, but the routes round here have multiple charging places along them.

There is no dependence on charging at the destination, although it is nice if that downtime can bd used.

Stopping for a pee has morphed jnto a charge discharge cycle ;)

Start undoing the work of the latter with a cup of tea from cafe or flask, and you can be on your way.

Chargers are popping up like a rash.

What I don't see are attended charging points. I'm old enough to remember when people worked the fuel pump for you. Given a surplus of cars over sockets at a destination that might catch on, and indeed anywhere that parks cars for you might return them charged.

Trailer brakes

We might yet see trailer wheels that regenerate, electric braking as with the main vehicle.

(Given those can double as motors, it would be tempting to drive it from its own battery as well.

Affordable, self-healing power grids are closer than you think

Scotland and wind

Currently Scotland can't export all its spare windowed to England, Norway and NI.

The connectors sre not big enough. This may change, OTOH there's more wind and tide/current there.

So setting up a "gasometer" or two next to an existing combined cycle gas turbine /steam plant and putting low pressure H2 into it when otherwise wind turbine operators would be paid to not make power seems at least plausibly sensible.

midgepad

The 1.2GW wind turbine? Very Big Panrls?

I tend to think of a power station as being 1GW, but that perhaps raises steam in a couple of boilers, and/or uses it to spin a couple of turbine-generator sets, and each can be switched off on occasion.

I suspect your 1.2GW wind power station is made up of several turbines.

I've not seen one larger than 16MW mentioned, but perhaps they are larger. Even so, they'll be 1 to 4 dozen to the GW, and arranged in groups, and the groups into groups and so on.

Which begins to look a lot like a small grid.

The solar panels on my roof are rated at 300W peak, let's say we can have big ones at 500W. That means 2000000 panels per GW.

Now we could wire all 2000000 in series and put out 60MV DC directly, but I think among the very many reasons not yo the old Christmas tree lights problem, one panel failing means the whole string does, is almost the least.

They'll be in rows of several dozen to a hundred, and wired to a sensible compromise. They may not even all be in the same field!

So again, modules, redundancy, and concentration, but not magically a single machine.

midgepad

DC and Carrington

AC grids could be arranged to survive the next Carrington event.

DC ones, I think actually cannot. It might not be absolutely impossible Physics, but you can't put a capacitor in there.
