  • xkcd #3214: Electric Vehicles

    Jump

  • Batteries only last 5 to 10 years max,

    Real world studies are showing they last about an average of 12-15 years on average, and every manufacturer has a warranty for at least 8 years, with many up to 10.

    A gasoline car can be fueled in 30 seconds

    The typical passenger gas station pump flows at 7.9 gallons per minute. For most passenger cars and trucks, with tanks between 15 and 35 gallons, that's about 2-5 minutes of pumping.

    A typical level 3 charger will take a battery from 10% to 80% in about 25 minutes. And chargers can be in places where gasoline pumps can't be, like ordinary parking lots and garages. So the dual purpose parking where you can charge the car while you shop at the grocery store or work out at the gym or sleep overnight at home is just a completely different paradigm from what we're used to.

    The average car lasts about 12 years, by the way. EVs last basically as long as ICE vehicles. Which also makes sense, because it doesn't have to mix the fluids that lubricate and cool with combustion residue and foul up the engine that way.

    So your data is out of date, and those fears that were commonly cited in 2015 have pretty much proven to be false for the technology that was around in 2015. Now, in 2026, there's been even more advances in managing battery/charging health and chemistry, with more of an infrastructure for maintenance, repair, and charging.

  • The main substance that burns but doesn't necessarily get metabolized is dietary fiber, which is a category of some different polysaccharides that burn but don't get (fully) digested.

    So high fiber foods would tend to give incorrect results in bomb calorimetry.

    Do you think "coconut water" is corporate propaganda and it should be called "coconut juice"?

  • If you remove the art from the context, would it still mean the same to you?

    Kinda depends on the artwork, right?

    When you know that a Eric Clapton wrote "Tears in Heaven" for his dead 4-year-old son, it does hit different.

    Picasso's Guernica also carries a lot of meaning from its context, in its anti-war message. The symbolism in the painting itself can be debated, but the context of time and place (and the author's chosen title) clearly conveys a message that war is horrible and that the specific bombing campaign on Guernica was cruel.

    Filmmakers love long one-shot scenes not just because of the content itself, but also because of the technical feats required to actually make it.

    The context can add quite a bit of meaning to art. It doesn't always, and often isn't intended to, but for a lot of artwork stripping away the context actually strips away some of the artistic value.

  • I feel like a lot of people miss the meaning of this one.

    A gunshot wound that creates a splatter of red liquid is very, very different in meaning from a splatter of ketchup. The comic is criticizing the type of person who criticizes art only based on the superficial similarity rather than the actual context and meaning represented by the artist's choices.

    Not every artistic choice has intrinsic meaning, and plenty of artists and art critics go too far in focusing on the "how" than the "what" in art, but I still think the "how" matters a lot.

  • “Glide Ratio Optimization in the Olympic Ski Jump via Cosmetic Penis Enlargement”

    Jump

  • Sure, it's possible, but the margin of error is pretty narrow for making up for unexpected turbulent wind or slight imperfections in how the person exits the aircraft.

    In a normal ski jump, even though they can move more than 250m through the air, they're never more than 6m above the ground at any given point.

    So jumping out of an airplane would require a level of precision that probably couldn't be safely achieved.

  • My Kill-A-Watt wattmeter let me know that I was using more power than my circuit supported

    Jump

  • A space heater is limited in its heat production to the amount of power that the circuit can deliver via electricity. Unless, of course, you use that electric power as a starter to release some of the stored chemical energy of the items in your home. At that point you can continue to produce light and heat even after shutting off the electrical power.

  • We don't fund sports for shit.

    That's wrong. A big part of the reason why the US dominates in women's sports generally is because our higher education funding system is based on a bedrock legal principle from Title IX that schools must spend as much on women as they do on men, including in extracurricular activities like sports. So as a result, with college football being a men's only sport that raises a ton of revenue, a majority of our universities robustly fund women's sports programs in a large number of sports.

    Plus the US has a relatively unique culture of youth sports associated with their school, sponsored by the schools and their funding.

    So we do fund a lot of youth and amateur (and semi professional) sports, indirectly through schools at various levels, including through whatever government subsidies and policies affect those schools.

  • Our duty

    Jump

  • are super active and do all kinds of fun things with their kids all the time.

    Some of the fun of parenting is sharing your interests with someone new, a complete beginner to that thing. Some of your hobbies become their hobbies (my kids have taken an interest in cooking and helping in the kitchen, love some of my favorite childhood books/movies, tinker with legos), and some of them don't (trying to teach my kids how to play chess or sports have been mostly unsuccessful).

    But it inspired me to take them to the library and museums and even vacations that I wouldn't have otherwise done. It also helps inspire me to keep in better contact with my parents and siblings (and their kids), because it's important for me that my kids have relationships with their grandparents and cousins. But the side effects is that it makes me stay in better contact with my own family. So it becomes a forcing function, that is only kinda a burden to the extent that I might rather be doing something else, that I learn to appreciate in the long view.

  • Different languages have different quotation marks. Using one's own native language quotation marks is pretty innocuous, but going out of the way to make specific formatting not used in any other language (both human languages and programming/markup languages) is what separates the two.

  • What you're talking about is an important part of the challenges of translation between cultures and languages. Words for categories don't always translate neatly.

    Take, for example, the English words for Lemon and Lime. Many languages don't distinguish between the two, and at most will call the lime a green lemon.

    The word for "seafood" in many other languages may inherently exclude freshwater fish, or all fish, whereas in American English it usually includes all fish.

    The two English categories of "bread" and "pastry" map onto three categories of "pain"/"viennoiserie"/"pâtisserie" in French, because enriched breads aren't considered bread.

    Many languages don't have a different word between red and pink, and instead just call pink "light red" or something. Some languages distinguish light blue from blue, and may define the demarcation between green and blue differently.

    I'm pretty sure there are languages that don't distinguish between alligators and crocodiles, goats and sheep, turtles and tortoises, too.

    With cultural mythologies, it's especially interesting on whether we decided to use the same words for the different culturally independent myths: dragons, vampires, zombies, ghosts, demons, devils, gods, demigods, fairies, wizards, etc.

    And so when talking about whether a culture or language distinguishes between mermaids and sirens, or whether they're considered the same thing, is just an extension of the broader observation that not everything translates neatly into the same categories across all languages.

  • It basically doesn't work out.

    Theoretically you could have 2500 square meters of solar arrays above the weather beaming the power down to a dish with only a 500 square meter footprint.

    But you'd still have to deal with weather with some kind of a storage solution. And 2500 square meters of area in space seems more expensive to claim than just 500 square meters of area on land, in pretty much any scenario.

  • Telepathy Club (OC)

    Jump

  • With telepathy, I do sometimes wonder if the telepaths see no point in making external facial expressions for the benefit of their fellow telepaths.

    People born blind still make facial expressions. It's hard wired into us to make the expressions, even for a tiny moment, and suppressing those facial expressions is learned.

    That's probably why I still laugh, cry, wince, widen my eyes in surprise, etc., when watching TV by myself.

    So I don't think telepathy would change that behavior.

  • The side effects they're finding are that it unexpectedly prevents Alzheimer's symptoms and other neurodegenerative issues, influences the brain to want to drink less alcohol and smoke/vape/chew less nicotine, and helps with chronic pain.

    The point, though, is that it makes metabolic changes by having people eat less. Pointing out problems with drugs that increase resting metabolic rate (so that they burn more calories without exercising) or decrease absorption of macronutrients in digestion (so that they take in fewer calories from the same food) doesn't really inform how we look at these behavior-altering and desire-altering drugs. They're losing weight by eating less, not by interrupting the relationship between eating and net caloric intake.
