Life in the future

A drone-brella. As someone who has had to deal with skin cancer thrice*, I kind of want one.

* I’m in the sun a lot and even the SPF70 isn’t cutting it for my nose.

    Dear Uncle,

    I wear a broad brim straw hat to protect my face, head, and back of my neck from the sun.

    If you don’t like that idea then try Zinc Oxide Cream, the white stuff worn by lifeguards, or try Zinka Nose Coat, for the funky colors.

    Sincerely, Someone You Know

    A drone would need an awesome loiter time to be of much use.

  3. Joseph Constable Says:

    I have been cut thrice also. Hats and even then sunblock. For the nose use a stick. Get baby sticks because they will fit into your pocket easily and can therefore be available for frequent reapplication.

  4. Will Says:

    I suspect that some of the materials and coatings of eyeglasses/sunglasses reflect the UV wavelengths toward the nose. If so, this would significantly increase the amount the nose sees in addition to direct exposure.

  5. Sigivald Says:

    Yeah, I just wear … hats, if I’m out in the sun a lot.

    (Contra Will, most eyeglasses plastics just block UV, so not that.

    The nose gets burnt easily because it tends to be oily/sweaty (and thus reject sunscreen easily) and it sticks out, getting more direct sun than the vertical face’s oblique angle.)

    Hey Uncle,
    You need to order European sunscreen. They actually put sunblock in it and remove the cancerous chemicals found in all U.S. sunscreens. A friend of mine that is a U.S. citizen from Switzerland and a doctor orders it for his family and will not use a U.S. sunscreen product, and a SPF-70 version of their product will not allow you to even tan. I’ll see if I can find the brand he buys, but there are several to choose from on Amazon.

    >At 150 centimetres (60 inches) wide, the parasol prototype weighs five kilos (11 pounds), and so far can only fly for five minutes on one charge.

    While I welcome the future, we’re a long way there. Maybe in 5 years we can make one that’s 8 oz, and can be powered for 2 hours at a stretch, but it will only function during windless days.

    “materials and coatings”

    “most eyeglasses plastics just block UV”

    IIRC, the proper terminology is “absorb, or reflect”. There are different plastics used, in addition to types of glass. Glass normally transmits UV. I think. Coatings are a big part of optics, and a lot can be done with them. I’ve forgotten a lot of my optical knowledge, it seems, sigh.

    If you you could have one of those US military Global Hawk worldwide drones circle above you with really extended wings and blot out the Sun while you played 18 holes of golf, that would be worth something …

  10. Sigivald Says:

    It’s 2018, man.

    Nobody has actual glass in their glasses; it’s too heavy and fragile.

    Polycarbonate, high-index for those of us who are basically blind.

    (And, yeah, everyone’s glasses have at least anti-glare coatings, unless you are incredibly, desperately poor and can’t afford the extra $3.95 or whatnot from Zenni.

    Most places seem to just do a UV coat standard, included, won’t even ask you about it, which is why I said “block” – it doesn’t matter how or the details, for Unc’s purposes.)

    @ExpatNJ, but “no one needs” to play 18 holes of golf…
