    High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

    If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

    Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.











  • If you really want to try some, you could use d-limonene. It’s just orange oil (like you get when you squeeze an orange peel), is edible, and is basically a kerosene-like hydrocarbon. It’s used in hand soap and works for stripping paint, and you can run multi-fuel camp stoves off of it, too!

    Careful ingesting it though, as it isn’t always food grade due to extraction methods/additives. It causes kidney tumors in rats, but the mechanism is known and is not relevant to humans.
