Where can I buy a large analogue meter?

Why are you obsessed with range? In any event, the range for EVs increased from a little over 250 miles in 2015 to almost 400 miles in

2020.

There are more than 10 million electric cars on the road worldwide. That's not penny ante.

This tech (and a lot of other new tech) works on internal combustion cars as well as electrics.

Takes one to know one.

It may be stuff specific for schools, not really for labs or industry.

Yeah, they keep saying that about computers, too. And they're constantly proved wrong.

Indeed. And a lot of that stuff just isn't made any more, like orrery's, which used to be in every gradeschool science class.

I'd _love_ to get my hands on one of those foot high by three foot long slide rules that used to hand from science lab ceilings...

Digital can give you what you want when you want it. It can be faster and sloppier than analog if that's what you design it to do.

Displays don't have to have any mechanical inertia.

Of course. Honeywell has been making integrated circuit pressure sensors for decades now. You've got to wrap some extra electronics around them to provide a display that the human plant operators can read, and the display is chosen to suit what the plant operators want.

in 2021, the patent office has on file millions of patents of which less than 1% actually proved useful.

They are completely right about computers. They cant be clocked any faster, they cant be made to work with much less power - all they can do is add more cores.

The only radical breakthrough in the last 20 years has been the solid state disk.

Curiously not invented by Clive Sinclair or James Dyson, but by real engineers working in large companies.

The new(ish) Apple processors use a fraction (between and half and a third) of the power used by an Intel equivalent.

And this feat of breaking the laws of physics is achieved by?

That by itself, says nothing A Z80 uses way less power than a pentium A motorcycle uses way less power than a ferrari.

I like the comparison between Z80 and Apple. About equally usable really.

I'm sure they're in some science museums. I guess now we have to make do with pictures on a computer screen.

That's not what they were used for. This:

commonly used for belting a noisy pupil, whacking the desk to make a loud noise to get attention, and waking up pupils that had fallen asleep by banging it on the desk 1 inch away from their sleeping head. I saw one get destroyed when it split in two. The single glazed window that half collided with was also shattered.

Make your own town names. Dundee belongs to Scotland and is where I was born.

Radical breakthroughs aren't how things happen. Slow and steady wins the race.

The new Green computers will be powered by the cooling fans in reverse Just keep th'm in the wind.

ROFL! I sold a wind turbine to a yacht person. I wonder if it slowed down the yacht in an equivalent amount to the cups of coffee he brewed with it.

It says everything. Less power for the same load - google Apple M1
