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...

Seems more analogous to clothes than housing


clothes can be "too big" in the sense that the extra size is detrimental to the function, which is somewhat different from houses.

And it's pretty common to have buy-nothing groups in cities or even at large companies. Got a loooot of hand-me-down clothes for my toddler from friends, family, and randos in the neighborhood.

In California, the major utility provider was found guilty in relation to wildfires, and fined.

Guess what happened to electricity rates...

The Chevy Suburban is about the same weight now as in 1973 (5837lbs then, 5785-5993lbs now, according to Wikipedia).

It was huge then, it's huge now.

The BMWs pictured are not the same class of car either


one is a coupe/sedan, one's an SUV, so of course they will be radically different.

Don't get m wrong, I think modern cars are too big and, in the case of BMW, way uglier than they used to be.

I also added a Makefile for mine (LaTeX), and it would add the commit hash to the front page (with an asterisk if the repository had uncommitted changes).

So, if I gave a draft to someone and got feedback, I'd know exactly which revision it was.

Yeah I always assumed "bug" was like "vegetable"


it's a colloquial, not taxonomic, term. But there are "true bugs" so maybe the analogy isn't completely sound.

(And tomato is absolutely a vegetable.)

As a social construct, I like that I can be anywhere in the world and know that around noon is probably an appropriate time for lunch, etc.
