[tim...]

the history of telecoms proves you wrong

tim

[tim...]

though in the case of EVs governments are putting polices in place now on the assumption that it will happen

tim

[tim...]

but I don't know who you are either

and it's better than TNP claims is physically possible

FTAOD, I have no issues with the argument that the necessary improvements aren't going to happen in less than 20-50 years. I have seen the paltry improvements that the past 30 years have brought.

It's with his claim that anything more than 2 or 3 times improvement is physically impossible.

I don't believe that the car manufactures care

they are doing what their governments are telling them they should do.

but if they have credible scientific evidence that what their government is asking for is undeliverable, their time/money would be better spent changing the minds of the politicians

Investing billions in something that you know wont work, just to avoid upsetting a few politicians is nutty.

In my time I have worked on many a telecoms project based upon a new common standard that turned out not to have the commercial traction that everyone thought it would.

But each time the whole team (developers/management) really did think that it would be a winner.

From what is being said here, you can't say this about EVs

I live in a small town.

one bus per hour (on each route - different directions) last bus 6pm, three buses in total on Sunday (per route)

Living without the use of a car is not "possible".

in order for 50% of the cohort to get an "A" they have to be

TNP has mentioned (more than once) lithium-air as something that has promise. You can read about it here:

You need to appreciate that there isn't any magic in this business. The number of battery chemistries worth looking at is limited, and they are being looked at. A practical battery is going to be quite complex, to say nothing of quite interesting when it goes wrong.

[Richard]

That's bollocks. It is possible, just not something that you'd like to do.

[tim...]

fortunately, rail electrification is measured properly

tim

[mechanic]

Yes we're told Moorside will provide 7% of future electricity requirements, so total requirements would be around 50GW. Yes we will need more capacity.

[Dave Plowman (News)]

Of course it is. People lived long before cars were invented. And there are bound to be some in your small town with no car or access to one.

Of course a car is more convenient. And that convenience means PT won't be used as much as if there were no cars. Therefore, a worse service. A viscous circle.

[The Natural Philosopher]

Don't lie. I didn't object to one order of magnitude. I objected to two.

[The Natural Philosopher]

Mow I KNOW ou are realy a cynical shill and not merely misled.

Double counting!

Heck if I buy a printer and they then charge me for the ink, is it double counting if I add the two together with the cost of the paper to get the cost of printing a page?

Do yu actually believe anyone actually believes you?

And the answer is in the physics. No. Not as the public would like it to be.

Some advance is likely. But not really enough at a sane price. And lithium is not inexhaustible either.

[The Natural Philosopher]

No,it proves me right actually.

[The Natural Philosopher]

Yep. I live in a similar place.

I could dispense with a car have all food and groceries delivered and use taxis from the nearest town for anything else.

It would be slow and inconvenient, but not impossible.

[tim...]

are you suggesting that telephone calls aren't a cost effective business tool then?

Because no-one would be making them if the costs of installation weren't initial subsidised circa 100 years ago

(and the same is true of mobile calls, but I will accept an argument that many use then in a non-cost effective way)

tim

[tim...]

but you are not adding together costs

you are adding together disadvantages

you cannot say that the disadvantage of something is X but to counter X we can do something else which has a second disadvantage Y and then say the total disadvantages of the first something are X+Y.

because by doing Y we have lost X

or we could have just stick with X and not done Y at all.

[The Natural Philosopher]

How come we built the internet and mobile phone networks entirely using private capital then?

Wanker.

[Martin Brown]

Apart from nuclear powered thermopiles as are used on some deep space exploration vehicles that go too far away for solar power to work.

[Martin Brown]

It is definitely stored as chemical energy in a battery. Some modern supercapacitors do actually store electricity as charge separation.

There is a choice of potential energy as in pumped storage of which the Welsh hydroelectric scheme leads the way or as kinetic energy as a fast spinning flywheel of which the system for stowing the MRAO 5km telescope was at one time the largest example - some busses used it in Switzerland even earlier. The flywheel would go a scary distance with tremendous destructive power if it ever broke loose from its bearings. It is coming back into fashion again for transport:

It makes little difference whether the energy is stored as chemical energy or mechanical energy. What counts is the overall efficiency.
