  • Because when looking to replace work horses with a steam engine you didn’t care what the absolute peak output of a horse was. You needed to know how big of an engine you needed based on how large the team of horses already powering the application was. Anyone trying to run a horse anywhere near their peak output for any length of time would injure them.





  • I’ve had that happen with what i assume was a hand lotion because there was a particular part of the lid that smelled.

    I don’t know why other people are treating you with so much disbelief. This absolutely can happen with people not thinking about how their habits impact what customers are consuming. With how many millions of coffee beverages that are served every day, it shouldn’t surprise anyone that some small portion are handled improperly with poor hygiene. It also shouldn’t be overly surprising if you’ve had it happen multiple times because you likely visit the shops near you. Such an event isn’t random and is the result of someone’s bad habits.


  • No, never. Current charging rates already get close to thermal constraints. Hitting those charging rates either requires accepting much lower power density or using way more metal per cell. This research might inform design changes to improve charging rates, but we’ll never see high capacity batteries charging in a minute.

    The researchers know this and only mention wearables and iot devices applications. The article author erroneously makes the leap to high energy density devices.

    If you don’t care about energy density at all, ceramic capacitors can already charge and discharge in microseconds.







  • Color-safe bleach seems to be Hydrogen Peroxide based, so you were probably safe.

    Traditional Sodium Hypoclorite bleach should never be mixed with vinegar. That can release chlorine gas which is very bad for you even at low concentrations.

    In general, use one cleaning agent at a time with thorough rinses in between. It can be hard to predict how cleaning agents will react. You’re likely to reduce the effectiveness of them by mixing, and there’s a chance of making dangerous byproducts.








  • I got long covid from an infection before the vaccines were available.

    Getting the vaccination and boosters noticeably worsened my existing long covid symptoms. I still got the boosters because I assume a reinfection would be much worse than the vaccine’s effects. If I ever thought I could reasonably avoid risk of future infections I would not choose to get more boosters, but since exposure is inevitable, I’ll deal with the consequences of the booster.

    When essentially everyone has had exposure to covid your statement can’t actually be tested. We don’t have a cohort of people we know got vaccinated but were never exposed to the virus.

    Anyway, the vaccine is worth getting because the alternative is being exposed to the virus without protection, but that doesn’t mean the vaccine is actually free of side effects for everyone.


  • Oh for sure. I do my best to avoid Amazon because most listings are full of made up lies. I know marketing is full of half truths and exaggerations, but I despise shopping at places that try so hard to deceive me.

    I just brought up Amazon since Amazon and monoprice are the most common options I see mentioned when people ask for alternatives to the overpriced options at best buy or whatever.

    Industrial suppliers can be more expensive, but the time and aggravation saved by shopping by specifications you can trust is frequently worth a modest price premium. I’ve switched to Digikey and McMaster for a number of personal purchases after realizing how much of a mental toll deceptive marketplaces carry.
