The newly elected Liberal Democrat council in my London borough tried
to introduce a scheme under which the cost of residents' street
parking permits would quadruple to Ł400 for petrol cars, and quintuple
for diesels, but fall to zero for electric cars. The idea being (so
they said) to encourage people to dump their Dirty Diesels and switch
to electric vehicles.

The imbeciles on the council had to be reminded that the only residents
who needed street parking permits were those who had to park on the
street, and such people couldn't have electric vehicles because it
wouldn't be lawful to charge them at the kerbside.

Many other arguments were raised against the scheme, but that had to be
one of the killers.

How many there already have EVs? I expect the EV issue was not an issue
at all and it was killed because the increased tax was not very popular,
especially with the diesel owners. Was there a meeting where they
discussed this? How many EV owners showed up?

On this subject you are just as willfully blind as Larkin, but in a
different direction.

Which bit of his last paragraph is difficult for you to comprehend?

You have been shown photos illustrating the problem in another city. Many
parts of London (and many other cities) are the same.

You haven't even been to the UK, yet you claim to know more about living
here than those that do. That makes you look foolish.

Often those closest to a problem can be blind to the solution.

More often ignorance of a situation leads people to
be armchair quarterbacks proselytising too simplistic
"solution" that won't work.

Mechanical engineers hate people that think everything
can be made from string and bent metal. Or there's the
"its only software", etc etc etc.


My post above is simply referring to the math.

Actually only part of the arithmetic, and for the
easy part of the problem. Unfortunately the difficult
bits need to be addresses too.


EVs in the UK are around
200,000 out of 37 million registered. That's about 0.5%. No, I don't think
there was any real issue with the number of EVs charging on the curb. It is
very much more likely the other 99.5% didn't like the bigger tax.

How much more simple can it be?

But then maybe you are right. Maybe the issue is a bigoted hatred for EVs.
Did anyone at the meeting chant "Make the UK Great Again"?

What on earth are you blathering about?

You refuse to believe you might not know everything
relevant, just like people suffering from Dunning-Krueger
syndrome.

In order to avoid recognising your ignorance, you seem
to want to invent conspiracy theories.

Away from electronics, you and Larkin are the two sides
of the same coin.

I'm perfectly happy with individual enthusiasts buying EVs, but I'm
not happy with powerful people and groups using them as expensive
power-building crusades.

My next-door neighbor Steve has always wanted a Tesla, so he saved up
and bought a model 3. He hated it. "It does what it wants, not what I
want."

I don't see it around any more. Maybe he got rid of it.

Actually, I do use a cell phone. I celebrated the moment when my brand
new Galaxy something was kind enough to die and switched back to Nokia
6020. Smaller, lighter, doesn't require frequent charging, has a normal
keypad with detectable keypress feedback, I am no longer by far the
fastest chain in the control loop and it sounds no worse than the
Samsung. Exactly what a phone should be.

My Casio Rock (flip phone) needs to be charged about every two weeks.

It's nothing but a plain old phone without a cord.

Only some fussy smart cell phones require recharging every 12 hours.

My Moto G lasts around 3 days between charges. It would last even longer
- almost a week if I lived somewhere with a decent mobile signal.

It was deliberately chosen to replace my faithful old Nokia which would

Sounds like charging my car! That's the point. Someone referred to the horrible inconvenience of plugging in the car every night. The reality is in most use cases a car needs to be charged a lot like a cell phone. Plug it in at home if you want, or plug in at work if that's an option. In Frederick they have level 2 charging at the train station so people can charge while they are at work and the car isn't!

This is early days still. In not too many years charging will be available everywhere you go, literally.

I've still got a flip phone to hold onto my old number. It is virtually unused save the telemarketer calls and the few calls from friends who don't have the new number (actually the really old business number I moved from a landline to the mobile).

Keeping the flip phone charged is more of a bother since I don't plug it in every night. It can go better part of a week and it often runs out in my pocket. The smart phone can go a couple of days but it gets plugged in more often because I think about it.

As to the car, it is much more of a bother to move things to and from the car each time I get home than it is to plug in the charger. Tesla has made it very simple and easy to perform charging. Combine that with the nearly complete lack of maintenance and it is a very trouble free car. They don't even have an annual service check like the hugely mechanically complex ICE vehicles.

It truly is amazing just how much the ICE has been honed and polished and what has been achieved with such an inherently complex and unreliable technology. Imagine how much improvement will be made with EVs over the next 20 years. By then, charging will be much faster (there are improvements to that coming in the next 5 years), longer range, lower cost. With EVs being nearly ubiquitous people will become complacent with the technology and expect TVs in every seat and a minibar. Actually, with fully self driving cars common, the minibar may actually happen. "I can drink, I'm not driving!"

We have a lot of electric public transportation here. It's very
reliable and works well underground.

And we have cable cars! One giant electric motor powers the whole
system. Cars going downhill donate their power to cars going uphill.

A cable car does have one lead-acid battery to run the lights.

Great fun, especially hanging on outside at night. The Hyde Street

There's none so blind as them's won't see.

Yes, I looked at the pictures and I see what you are talking about. The RF guys talked about this, but it is hard to grasp without seeing a picture. The US pretty much doesn't have this. Streets are 99% wide enough for parking and traffic.

That picture doesn't indicate that facilities can't be added to allow charging. The fact that with less than 0.5% of your cars being electric (and that figure includes hybrids which I expect most are) there are people working to solve these problems shows that others are not as adamant there are no solutions.

I'd be willing to bet when cars first appears in London there were many who complained about the smoke and noise and how they frightened the horses. Yet progress continued and I don't think I saw one horse in any of your photos.

Charging is not an intractable problem. In the UK it is difficult in some areas but will improve.

A sensible question, just as it is with any cloud service.

But the same is true of just about any car. The only solution
is diversity of supplier. That's beginning to happen with EVs.

Unfortunately EVs like Tesla have the EV characteristic
conmingled with the "driverless" characteristic - principally
as a way of distracting from the less good characteristics.

Temperature is controlled by adjusting the flow rate through the heater,
but for a 10kW shower the element is usually tapped so you can have
lower power for hot days when the input temperature is high.

Why not use a triac?

Phase control would cause unacceptable input current waveform distortion.

Pulse-skipping would avoid that but could cause flickering lights and other undesirable effects when switching 7kW.

They are not something that is high on the list for repair. There have been a few replaced although in many of those it was not the cells that caused trouble, it was the surrounding circuitry that is in the battery pack. These items are mainly off the shelf electronic components and so probably repairable even without Tesla's assistance if needed.

Not everyone truly understands the concept of rechargeability. John often needs things explained to him using small words.

The reality is that not only is an EV a way of driving without being totally dependent on carbon emitting fuels, it also costs less to fuel and is much lower in maintenance as well as having a much longer lifespan. So it's a win, win, win,... uh...


win!

I guess Larkin is the guy in the Volvo commercial from many years ago who asks, "If they weren't so good, why would I buy so many?"

Yes, that's right. The guy in the commercial was another idiot.

I was surprised how common it is in the UK to have instant electric
water heaters for showers, often 10kW or more. Here is a typical example:

Two year guarantee? Labor probably not included. Interesting that it
has temperature control *and* power control. "Sure, I feel like a cold
shower today because the grid is stressed."

Temperature is controlled by adjusting the flow rate through the heater,
but for a 10kW shower the element is usually tapped so you can have
lower power for hot days when the input temperature is high.

Why not use a triac?

I'm not a shower designer, but the method used works well and is
reliable, I guess it's cheaper too. And you'd still need the flow
control knob unless you restrict the flow to something which 10kW at the
coldest input could heat adequately.

Cheers

That sounds like a lot of complexity to take a shower. We have a
gas-fired 80 gallon hot water tank and two knobs in the shower, hot
and cold.

I like long hot showers, because I have ideas in the shower.

One is that distribution is sized for an average of

So are these two problems being presented realistically?

Bogus. I can't believe houses don't have enough
current capacity (2kW/230V = 9A) to run 1.5kW
microwave ovens, dishwashers, washers, electric
dryers, lights, TVs, HVAC, and a few electric
water heaters. In my visits to England, they
even had heated towel racks in their bathrooms.
A household without those basic amenities isn't
going to be buying EV cars anyway.

My car charges in 4 hours overnight, taking only
1.4kW while doing so. I've driven 4k miles so
far, and still have 80% of my second tank of gas.

The infrastructure Rick is thinking about is for
level 2 fast charging, which might be useful for
a few long trips, but not for everyday commuting.

I just wonder if UK leaves EU if they will go back to 240 V ;-)
Or maybe even 380 just to make a difference.
US 110 is also a possibility, if trump says so.


In the end the whole climate hype is a hoax,
climate change is not human caused,
it is set by orbital parameters:

And solar variation. Possibly galactic cosmic ray flux.
