  • Perhaps they were thinking of an American doctor.

    The bowling pins are for hitting the patient on the head because that’s the only anesthesia they can afford. The ducks are the little birdies circling the patient’s head after the anesthetic bludgeoning has been administered.

    The first gun is there because America and the second gun is so you can double-tap the patient in case you suspect they might be an immigrant.

    My girlfriend got herself a pair and taped them to corners of her desk. She doesn’t want to turn on the light when she gets up at night but she also doesn’t want to bump into the desk. Tritium vials fit that use case well.

    Could we have gone with dimmable lights or something homebrewed with low-power LEDs? Sure, but tritium vials are affordable and don’t need a power supply, a remote, or much in the way of setup; they’ll just keep doing their thing for about a decade before you have to even think about their light output.

    They’re a solid choice if you have the specific use case of wanting something to be easily located in (near-)complete darkness but you don’t want to use electricity for some reason.




  • Unless other situations where the established technology wins due to inertia, sodium ion batteries have two benefits that make them interesting regardless:

    Firstly, they are safer. A punctured sodium ion battery doesn’t catch fire, which massively simplifies safety design. That makes them very attractive for certain scenarios, especially ones where density is a secondary concern. That in turn means they get further development money instead of withering on the vine.

    Secondly, they require fewer hard-to-obtain materials, which makes them attractive from a strategic perspective. This one should be less important than the safety factor but it’s also relevant.

    I’m pretty sure we’ll actually see wet sodium cells in the wild if they are actually practical. Sodium ion tech is already being commercialized and if this brings it within the same ballpark as lithium ion then it becomes a very interesting choice for vehicles due to instant crash safety gains.
