My hunch is that this is not restricted to TikTok…

I particularly like the truck/engine correction.

FTFY

But “included” doesn’t mean free. You still paid for it.

Baking is chemistry, cooking is jazz.

I’m curious how the battery percentage went up

Physicists hate this one weird trick…

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…

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.

Isn’t universally funny.

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.

The exorbitant PG&E charges are usually “delivery charges,” not the “generation charge” iirc. So we’re paying reasonable rates for cheap, clean energy, but we’re getting charged out the ass for getting the electricity to our home.

It sucks either way, but charging for delivery sucks more because on top of it all if we run solar and sell back to the grid we only get the generation charge (which is minimal). At least, that’s my understanding — we don’t currently have a home solar installation.

It’s overpriced hardware

Have you seen the M4 benchmarks?

If you’re memory bound then sure, you can get way more bang for your buck with Intel/AMD. But for pretty amazing CPU performance I think the “Apple is overpriced” trope isn’t really true any more.

If you don’t want to sail the high seas, and you don’t want to pay, the library is a great, free option.

Many, many (most?) commercial ham radios are powered by ~12VDC, and can be run directly off of a car battery in many cases (always use a fuse, kids!).

Olive oil is delicious, and I’ve always loved acidic foods — so long as there’s yummy dressing on the salad, sign me up.

Just get in the habit of making simple dressing, e.g., EVOO, red or balsamic vinegar, Dijon mustard, salt & pepper. (Mustard helps with emulsification.) Yes oil is caloric, but afaik this is much healthier than drowning your salad in ranch or Thousand Island or whatever.

Olive oil can make you feel full, too, so even though you’re eating fat, it can be a net win.

A Mediterranean diet is delicious, vegetarian/vegan compatible and, I think, fairly healthy. But mostly it’s the delicious that counts.
