The EV fact thread

[markjay]

Or, maybe never. You cannot discount the idea that current batteries are as good as they'll ever be. Decades of research and still no cure for cancer...

But discounting the idea that current batteries can be improved, is fine....?

(BTW, massive advances in cancer treatments were made over the years as result of the research, even if a one-off magical cure hasn't been found yet)

More disinformation. FCV do NOT store electricity - they generate it. In engineering, facts matter.

FuelCells store electricity in chemical form. Strictly speaking, electricity is never really generated, the particles' electric charge is always there, we simply create a difference in potential by moving electrons around.

No, but relying on a notion that they will improve with no evidence to substantiate that assumption while simultaneously binning and banning everything that is known to work and can be decarbonised is folly.

The want of a universal cure means my father will never drive an EV.

Is that a realistic assertion or is at akin to the 'most abundant in the universe' spurious claim? I suspect the latter as without the hydrogen there is no PD and without a PD there is no flow of electrons we refer to as 'electricity' and without electricity it isn't much of a 'battery'. Further, the FC does not 'store electricity in chemical form' as the other chemical is hydrogen and its storage isn't in the FC but in a grossly inefficient storage tank.

So your view is that we should stick with horse drawn carts ICE cars forever?

Actually they do store electricity - the fuel cell doesn't power the motors directly.

We haven't really seen any major advances in cancer treatment - in the sense of cure. What we have is better screening and some better management and some improved surgery techniques.

I don't think you can discount that batteries will improve. But I think the reality is that all we're seeing now is small increments. And any substantial improvement invented today will take a while to actually impact on the market - and likely take a while to become cost competitive.

So for now we have .... what we have.

FuelCells store electricity in chemical form. Strictly speaking, electricity is never really generated, the particles' electric charge is always there, we simply create a difference in potential by moving electrons around.

The electric current is generated via a chemical reaction. Like a battery. But in a fuel cell that chemical reaction is a bit more like a solid state combustion process.

Do they 'store electricity'.

Capacitors arguably store electricity. OTOH batteries and fuel cells have a chemical state.

I can tell you from very first-hand experience that (luckily for me) you are absolutely wrong..........

That's personal.

What about the wider picture - where are the substantial benefits across the whole population.

I don't see anything radical. Bowel cancer is widespread. Have treatments changed radically? I don't think so. Screening has. Treatments have been refined. But there's no wonder drug or treatment that has made it vanish. It's all about better detection and refinements in treatment. A sum of gradual increments.

There are some examples of radical improvements with wide impact. Two I can think of - stomach ulcers and heart stents.

But cancer ? I'd say the prevalent nasties are still prevalent and still out there.

The particular treatment I was referring to, wasn't invented personally for me. Very many people benefited from it.

The treatment I received was developed (in part) by Cambridge Pathology and by Roshe.

Your chances of surviving any of the cancers today is significantly higher than (say) 20 years ago.

Jesus Wept, Why are we even comparing Cancer, a horrible disease. To a ****ing EV battery. Which idiot started this nonsense.

Agreed. Commercial Li cell technology is 30+ years old so pretty mature now ... most recent 'improvements' have come from simply fitting bigger packs and increasing the power output of charging points to keep pace.

But IMO it's quite likely there will be another step change in energy density one day, as we've evolved in the past from lead/acid to NiCd to NiMH to Li Ion. There's always something promising on the horizon and at some point one of them will become a practical proposition.

The statement might well actually be true within context.

Look at the impact that the railways from the 1850s to 1900s - which is often forgotten - and then look at what has happened since. In terms of people's every day lives and the perimeters within which they travel then arguably the tangible impact of what has come since is not as great.

A post related to the EV user experience:

I used one of the new Gridserve EV services today for a quick 15 min ‘volt and bolt’…

Excellent services, ‘AI’ powered food store - and super clean. Worked well, just tap card, grab what you need and walk out.











Absolutely loads of DC chargers, as well as a few AC - no queuing etc.

There’s a few of these ‘EV only’ services around now, the future looks promising.

I’ve noticed a distinct lack of actual practical EV content on this thread lately. It does seem most with lots to say haven’t even ever owned one.

That looks impressive, I must Google where they are so I can have a look.

Bizarre statement. The railways created arteries and opened up vistas beyond the local town.

But that’s as nothing compared to the transformation caused by the lorry, motorcar, motorbike, container shipping and the airplane.

With the 21st century kicking off with the “Dotcom era gift” of global fibre networks, globalisation, remote working, and of accelerated global migration, we still ain’t seen nothing yet.

We’ve come a long way from stage coaches travelling expensively over “high ways” that avoided the boggy trails of the low trails, aided by “Huts” where horses could be changed and food purchased.

The railways were transformational. The extent of this is to some degree lost because we have seen railway infrastructure pared back and the prevalence of road transport has eclipsed it. But I think the level and extent of change that the railways brought about is greater than what has come since.

People tend to look at long distance passenger travel as significant. But the railways made mass commuting viable. We take it for granted that perishable foods can be delivered to consumers. The railways managed to transform that too.

It's the boring stuff like that which is the real transformation.

The railways must have been viewed as transformational in the early years. You see it very strongly in that periods novels e.g. Dickens and Thomas Hardy. Whether they were profitable or not is another thing and they certainly haven't made a profit in the last 100 years. The long term lack of profitability is even discussed in the National Railway museum. If railways have struggled in the past when labour was cheap there is zero chance they will ever be financially viable in modern times while the unions are in charge. I don't understand why we persist with such a dysfunctional method of transpiration. If they can't be made to work, tear up the tracks and run self driving buses instead.
