and energy densities are about a factor of one hundred smaller than
that of kerosene.

Yes. But the problem with batteries in general is that their power
and energy densities are about a factor of one hundred smaller than
that of kerosene.
How do you calculate the energy density of battery, per pound?The battery contains so much total energy in watt-seconds (Joules),
has a mass of XX grams and occupies YY liters of volume, and can
deliver power (watts) at maximum rate ZZ.
The issue is particularly acute for airplanes - one cannot fly across
the Atlantic or Pacific in a battery-powered airplane. You'll get
maybe 200 miles, then splash.
And how about the shipping costs of kerosene vs. electricity?For a vehicle, shipping costs are not the issue at all, but shipping kerosene (or coal) is far cheaper than electricity, which is why there
are multitudes of local power generation plants versus five or so
immense central power plants and a lot of transmission systems.

But we have to consider incremental shipping costs. If we have to use one additional gallon of gasoline, it might come from the middle east or Russia, and we are spending billions in energy costs (wars).

We choose to outsource acquisition of oil and gas to less fussy

mine minerals ourselves. But there is no non-political reason why we
cannot drill and mine in the US.

With switching regulators, "voltage decay" isn't a problem.
Any technology that is novel, pivital, profound and promising is
probably also bogus.

Joe knows so little about reality. Presently, the US exports more crude oil than we import. The problem is not getting it out of the ground. The problem is that we then burn most of it, which releases carbon into the atmosphere. But then, I suppose

When the argument turns ad hominem, it's a sign of lack of ammunition.

Ad hominem. Running low on ammo again.
What you are looking for are Ragone charts, which plot specific power
density versus specific energy density, of both weight in kg and
volume in liters, on log-log paper.
When one does this, fossil fuels and combustion engines are in the
upper right corner, and all battery stuff is down toward the lower
left corner.
But it's hard to find Ragone Charts covering both batteries and fossil
fuel. Mostly one sees only plots showing only the battery corner.
But it matters a lot for aviation. Consider this, reported by

charcoal or whatever? Supercaps are even worse than batteries by about >>1000:1. Somebody stores a millijoule and does a press release.
The basic reason is to handle pulse loads that solar cell sources
cannot. People use flywheels for the same reason.
The big breakthrough would be the invention of a far better
superconductor than what we now have. This would solve a number of
problems, including:
Energy storage, in a big super conducting toroidal inductor.
Fusion by magnetic containment. Current containment fields are far
too weak to be leak proof despite a host of small but significant
leakage processes. Having ten time the field would likely suffice.

charcoal or whatever? Supercaps are even worse than batteries by about >>>1000:1. Somebody stores a millijoule and does a press release.
The basic reason is to handle pulse loads that solar cell sources
cannot. People use flywheels for the same reason.
The big breakthrough would be the invention of a far better
superconductor than what we now have. This would solve a number of >>problems, including:
Energy storage, in a big super conducting toroidal inductor.
Fusion by magnetic containment. Current containment fields are far
too weak to be leak proof despite a host of small but significant
leakage processes. Having ten time the field would likely suffice.
Joe Gwinn
There was a plan for a miles-diameter superconductive inductor, flat
and not a toroid, for energy storage. It would confuse birds and
compasses in all directions.
Superconductors can't make super high fields. MRIs are teasing the
edges of self-quenching.
A quench is fairly dramatic. I've seen quenches of smaller NMR
magnets, which are not dangerous in a big room.

Yes, Bozo, lithium batteries DO catch fire at random - there are numerous examples of that happening. The latest PRIME example is that of the car carrier that caught fire off of the Netherlands, sinking the ENTIRE SHIP.

I doubt that any battery monitoring system is going to catch a defect that expands into an inferno in seconds.
Even if something did detect a short, what could anybody do about it? Dissasemble the battery pack in seconds? In a car surrounded by other cars!

You get a much earlier notice than that, and you just discharge the battery (not fast enough to heat it up appreciably, and the battery monitoring system will allow you to keep track of that).

Discharge it into what and for how long? According to <https://ev-database.org/uk/cheatsheet/useable-battery-capacity-electric-car>,
the average capacity of an EV battery is around 70kWh. What discharge
rate would have a measurable effect to stop the battery heating up appreciably in less than a few hours, and other than discharging it into something producing heat, what could be used, and how could it be
connected up?
Would it be possible to use the charging socket "in reverse", and take
power from the EV through that? Perhaps the simplest and safest way
would be to have a tank with a couple of cubic metres of cold water, and discharge the EV battery into it through a heating element similar to
those in electric kettles.
Any other ideas?

New York City is averaging hundreds of fires a year, with dozens of deaths, started by lithium batteries in scooters and such. It's not a trivial issue.
Those fires are most likely in cheap imported bikes and scooters, but even Teslas explode now and then.
I doubt that any monitoring technology will reduce the battery hazard much.
I've seen videos of scooters exploding like a bomb.

How do you calculate the energy density of battery, per pound?
And how about the shipping costs of kerosene vs. electricity?
