  • 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.

    I have a combination washer/dryer unit. It doesn’t do a great job at drying, but it does remove enough of the moisture that it takes a couple days to get musty. It’s nice that I can just stick a load in before bed, and besides wrinkles, there’s no problem with me not getting to it for a day.

    The combo units have tiny drums and take longer than separate units. They wouldn’t be suitable for a family with kids, but for just two people It’s been pretty convenient.


  • I’m sure avoiding contaminating the sample was the requirement that had them acting very cautiously. The comments saying that an angle grinder could have it open in 5 minutes were so annoying. Of course NASA engineers could bust it open if that’s all they cared about. The whole point of collecting a sample is to take extremely precise measurements of the contents. Any grinding wheel or saw, would risk adding contamination that would mess up the analysis.
