One thing to keep in mind

the US is huge, both geographically and culturally. Flying from Los Angeles to Boston is further than London to Baghdad.

And likewise, the cultural "distance" between, say, New England or the Pacific Northwest and the deep south is extreme.

Of course there are things that affect (nearly) all Americans, but some context is important.

But this applies to the UK, Ireland, France, Belgium, Italy, Spain, Portugal, and...well...much of the world, if these data are to be trusted.

But "included" doesn't mean free. You still paid for it.

I'm curious how the battery percentage went up

Physicists hate this one weird trick...

Exactly. And it includeded a 500GB m2 (SATA, not NVME, but still), with a spare m2 slot available. As opposed to an SD slot + USB port...

Dual gigabit NICs and importantly can be configured to boot after power loss (which the pi of course also does).

And Intel QuickSync may not be perfect but it is well supported with mainline kernels.

Only drawback is that it draws a few extra watts compared to the Pi.

Is that true though? As in, is it really that dangerous? It seems that you'll dissipate power equal to the inefficiency times the nominal charging power, so something like 5V x 2A x inefficiency (inefficiency being 1-efficiency), which will probably be of order a watt.

I can use my car battery to charge itself without any issues

I just plug the red terminal to itself, and same with the black, which is to say, a battery is always connected in a way that "charges itself."

I think the key is that the battery probably isn't really playing a big role in OOP's setup

electricity doesn't "go through the battery," it just goes from the charging input to the power output circuits, with the additional power (due to inefficiency) being provided by the battery.

I'm not sure though

the power output and the charging input are both regulated and (almost certainly) current limited. So I think (not positive...) that you're basically dissipating your power in the inefficiency the charging and output circuits, with this power coming from the battery.

The inefficiency should (I think...) just be the round-trip inefficiency of the charging/discharging of your power bank

this should be way, way less than the short-circuit power dissipation.

The simplest toy model is to take a battery and try to charge itself. So you put jumpers on the + terminal and you connect those to the + terminal, and same for - (charging is + to +, NOT + to -). But this is silly because you've just attached a loop of wire to your terminals, which is equivalent to doing nothing. With charging circuits in between things get much more complicated, but I'm not sure if it goes full catastrophic short...

I switched my home server from ARM SBCs to a $140 N100 (16GB) and honestly it's a real improvement.

I love the original concept of the SBCs

affordable and efficient, with hardware acceleration for compute-heavy tasks. But the reality for me lately has just been more trouble than it's worth, and running a mainline kernel on x64 is such a better experience. (I'm mostly griping at the Orange Pi I had

RPi tend to have better SW support.)

For 75kg (roughly average South Korean male weight) and 7" step height (standard in the US I think, not sure about Korea), this is about 0.13kJ/step.

By coincidence, the human metabolic efficiency is (roughly) the same as the conversion between kJ and food (kilo)calories, meaning this would be (very roughly) 0.1 calories/step.

Not much, given a single French fry is maybe 5-10 calories. But it's better than nothing!

good enough simulations that you can't tell the difference.

This requires us having actual conversations with those dead people to compare against, which we obviously can't do.

There is simply not enough information to train a model on of a dead person to create a comprehensive model of how they would respond in arbitrary conversations. You may be able to train with some depth in their field of expertise, but the whole point is to talk about things which they have no experience with, or at least, things which weren't known then.

So sure, maybe we get a model that makes you think you're talking to them, but that's no different than just having a dream or an acid trip where you're chatting with Einstein.

My city has a fleet of vintage streetcars that it runs on standard routes (i.e., it's not just a tourist novelty

and it's the same cost as bus and other light rail).

It's always a joy to ride those and read the history of the individual streetcar

they all wear fun livery.

Our home averaged 7.5kWh/day in December (we did not travel and we're home with family the entire time); this is about 10x less daily energy than the battery capacity of a modern EV.

Now, we have gas heating and stove/oven, so that adds a huge amount of load

but my numbers above are for 24hr energy, and batteries wouldn't need to supply that whole time.

Of course, this doesn't address cost, and it doesn't address natural resources, like you mentioned. But that actual required amount of energy per capita can certainly be achieved with current battery technology.
