Even there we have quite practical solutions.


What are they?

(You won't answer. Ever. Because you don't they don't exist.)

It is very likely
that we'll see massive numbers of charging stations installed by
power companies over the next couple of decades,


At $50,000+ (or $350,000) each, along the street in questionable
neighborhoods, when scrap copper is running nearly $3/pound?

Your high, dude.

since electric
cars are likely to provide load balancing for local power grids.


Electric car will be charged during business hours, and in the
hours after people get home from work. These are known as "peak
hours" to people who aren't retarded.

Indeed, we'll see cars charging their batteries from the stored
power in other cars, as well as stored power in household and
business systems.

After trillions of dollars in upgrades to power generation and
distribution systems, you're still hallucinating. Seriously, dude,
take your meds.

Keep drinking that Kool-Aid, son. You're gonna need it.


It's true that the United States didn't go metric, it's true
that they didn't scrap the dollar bill for the Susan B. Anthony
dollar.


Neither of which has anything to do with the obstacles to the
universal adoption of electric cars.

In most of the world, though, the government does do what it
thinks it needs to in the name of "progress" even if the people
are kicking and screaming.


The word for that is "fascism," and only a retard considers is a
good thing.

Switching to electric cars could be
another case like that.

No doubt. Fascists are like that.

Nothing that doesn't already exist is certain. I mean, we still
don't have a cure for AIDS.

And, of course, even if they develop much improved batteries
with much greater capacity, the amount of current needed to
charge them with the power needed for a long journey won't
change.

Of course, a new generation of electric cars based on fuel cells
could get carbon-free chemical fuel - like hydrogen. That would
work.


Do feel free to explain how that hydrogen is generated, in a carbon
free way. And how that electricity used for it (now you're well
*over* a trillion megawatt hours per year, since hydrogen takes
more energy to separate than it delivers when burned) is
distributed to the cracking plants through a grid that does n't
have the capacity to handle a 50%+ increase in load.

Or not.

Hydrogen is snake oil, peddled by scam artists who want to suckle
on the public teat.

Some things are certain enough.

Your delusional idiocy, for instance.

Poor people don't usually have a summer cottage in the country
to drive to on weekends. So they won't need a second car.


You are literally hallucinating. Get help, dude. Before you hurt
yourself if you believe that poor people never take long drives.

In fact, they will probably take the *bus* to go to work. This
is not some radical new concept. Yes, public transit in many
U.S. cities is not very good. Since cities in other countries
have decent public transit, though, clearly no law of physics
has to be violated to provide it.

You've just condemned 11 million people in Los Angeles to slow
starvation due to the utter inability to get to work. Really.

Very fascist of you. (Nothing new about that. After all, there are a
lot of brown people in LA, so the only surprise is you're not
demanding it be nuked.)

I thought the US had 110V in their outlets. Did thar change? Did
you switch to 50Hz as well?

Most of the outlets aer 110 volts. But the service coming into the
house is always 220 volt, three phase, which is commonly split into
two 110 volt sides. (Except when there's 440 volt three phase, which
is rare in residences.) Electric stoves and dryers (which generally
requires 200 volt, 3 phase) are common enough that pretty much all
homes have it available (I suspect it's required by building codes,
in fact).

Perhaps there are theoretical solutions, even practically? :-)

I'm still waiting for one of the EV True Believers to explain who
tens of millions of people who live in rentals (many of them with no
off-street parking) will get access to a charger. Or why employers
paying minimum wage would install $50,000 (or $350,000) charging
stations in their employee parking lot.

Or how to stuff enough energy down a copper wire to drive 300 miles
in a few minutes with less than 3 megawatts.

I'll be waiting for a long, long time.

3MW isn't needed by an electric car, that's the power needed by
a typical railway engine!

That's what required if you want to transfer energy into an electric
car as fast as a gasoline pump can. I can gas up my Toyota enough to
drive 300 miles in 3 minutes. To do the same with a $50,000 fast
charger would take something like two hours.

A typical gas station out on the interstate would need a 30+ megawatt
power feed to service as many cars per day as they do now, and would
need a dozen times as many stations as gas pumps because it takes so
much longer. The only way to improve that is higher amperage.

Now imaging a cable with three million watts of electricity in it -
enough to literally explode if it shorts out - in the hands the
drooling moron who was next to you on the freeway on your way to work
this morning.

They have 220V in some special outlets, such as the huge one that the
stove is plugged into.
