NASA's biggest worry right now: What if something goes wrong with the Webb telescope?

How long is "now"? If you don't want to specify a time interval,
you should talk about TW instead of TWh.

That would be per year. Versus, IIRC, somewhere between two and three
TWh/year of electricity currently being used. So a 30-50% increase,
which would require trillions of dollars in new generating capacity
and grid upgrades to handle. Doable, certainly, but not in less than
generations (the same time scale as was required to build what we
have now).

I didn't say that. You can rent a different kind of car. You
can own two different kinds of cars. You can be part of a
shared car pool (that's going to be increasingly popular given
the waste associated with exclusive car ownership).

Or you can use public transportation.

For a road trip to Yosemite? Or Nebraska? Or "out to the desert"?
You're smoking the same Kool-Aid as Chris is. You are literally
delusional if you believe that "public transportation" can replace
gasoline powered cars for long road trips.

(Not to mention, even if it did, those busses would still be
hydrocarbon powered, because electric just can't do it.)

Well, certainly not by the sheep that live there.

Well, it is true that there are such things as
superconductors... I thought he was still referring to the
situation of these apartment dwellers, not the laws of physics,
due to the context.

Even there we have quite practical solutions. It is very likely that
we'll see massive numbers of charging stations installed by power
companies over the next couple of decades, since electric cars are
likely to provide load balancing for local power grids. 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.

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

More likely at a few hundred dollars each, burdened to a few thousand
at most by installation costs.

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.

And electric cars will be drawn upon during peak hours, as well. Not
every car requires a full charge.

power in other cars, as well as stored power in household and

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

More likely tens of billions of dollars. Which is nothing.

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.

Three-phase power is common in industrial settings, but very rare for
residences. Houses receive split-phase feeds, which is single phase.

The fellow is being absurd.

_No one_ has disputed the fact that the US does not have the
infrastructure to support large numbers of EVs; nor that would take
considerable time and expese to get the US to a place where we could
sustain millions of EVs on the road on a daily basis.

He didn't say that. He said that public transportation is one more
option of many.

Buses aren't the only type of public transportation. And electric
buses are most certainly coming along. It is easier to electrify a bus
for long distances than a car. And even if they are hydrocarbon
powered, so what? The goal is to reduce carbon emissions, and a long
haul bus often produces less carbon per passenger than a car.

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.

If that's your requirement, 3MW isn't enough, you'd need more like
30MW. There's only one practical way to accomplish this: to swap
batteries.
