    Help Brainstorming for a NON ELECTRICAL Flashlight

    Just as a brainstorming session...

    I was thinking it would be fun to design / build a non electric flashlight, kind of antique, either candle or oil powered... similar to the automatic (non electrical) high end Swiss watches...

    The question is what to do, how should it look like, in an ideal world I'd like something ingenious.. some manual / automatic mechanism that makes it special, like the automatic winding with the watches....


    So what would you like to see in a non electrical flashlight.... post your ideas... if we can find a compelling package we might even try to make it work.... since it is non electrical it would probably have to be flame based...

    Here is what I can think off - not nescessarily all combined in one light...

    • High end Gear Mechanism to keep flame level
    • Glass Optics / reflector to focus flame into a narrow beam spot
    • Pneumatic oil supply system
    • Very small AAA sized - flame/oil based light
    • Cable based system that does stuff....



    What else.. go to town.... the perfect Davinci Era flashlight... anything goes but electrical...

    How about something like this, 3H 60 micro Gas acrylic tubes titanium coin edge on top and bottom with sapphire windows, the coin edge parts would turn using 30 small bearings. No LE as in picture. Or an acrylic tritium 3H tube in the center.

    I believe you've caught the steampunk bug. It's ok, I have it too.

    Here's my thinking-aloud rambling in the hopes that it'll fire off some ideas for you. In some sense, a Zippo is a non-electrical flashlight, though I know this isn't really what you're picturing. One design limitation is of course that flames and their heat want to go upwards, and flashlights are generally horizontal tubes. Imagine fireplace-lighters--probably not the aesthetic you're going for, but you could buy one and see if you could work out the limitations/lensing possibilities of one of those before making the mechanism that would actually light it/keep it lit. Might be neat to figure out a reflector/lens system that would focus a flame and make it flashlight-like. I like to be systematic about my projects and would personally probably start there first.

    Apart from some smart-aleck responses (like a colony of fungi that glow in the dark), I'd vote for something using fire as well.

    Unsure on whether oil or gas would be better, but in either case I'd surround it with a candleluminescent material. It pretty means a material that will emit light very efficiently when it's in a flame, like the stuff they use in lantern mantles. Not sure how hot it needs to get though. The loss in light that's blocked by the mantle is more than compensated by the light emitted from the mantle. There're various combinations of material available, but one of the more common ones involves thorium (ever heard of the radioactive boy scout?). That in itself could open up some interesting things (take that you puny tritium vial!). We'd need to isolate the flame and other gunk from the phosphors though, unsure how.

    Regardless if a mantle is possible or not, we could do any number of things.

    Focussing wise, I'd go for a reflector made from a solid piece of metal, ideally no specialised, fragile coating, since I suspect we'd have to clean carbon off it fairly often. If there's a coating that is physically and thermally resilient enough, that would be neat. The reflector might have to be thermally isolated from the handle, dependent on the temperature though. Lots of good thermal insulators out there that are pretty cool,

    That said, with the large emitter size, I really would go for a more flood type light and ditch the whole "tube with light coming out one end". I'm drawing up something right now, I'll edit it in a bit later.

    Edit:
    So here's what I'm thinking, your comment on watches started me off. Pocket watches, to be precise.



    Size is about 60 mm dia, height 30 or so? Might be a little high, but the concept is still the same. Pocket watch is only there for size (I made it few years back, just chucked it in for scale). The lid can serve as a sort of reflector if so desired, but given how shallow it is I'm not sure how useful that'll be. Maybe not have the lid as a full cylinder, but only part of it? Other random thoughts:

    I sort of drew a rack & pinion system in there attached to the lid, that could do any number of things. Two that come to mind are:
    Raise the nozzle, mantle or whatever when the lid is opened.
    Ignite when lid is opened.

    I drew a cap and a knob in there, keeping all of the stuff for refueling, power and all in there would make for a nice exterior. Not sure how that would work if opening the lid causes ignition though.

    Exterior, maybe have the fuel container surrounded with Ti rods, like the Gatlight? Space for engraving, carving or any number of things.

    Well, that's my crazy idea out there.

    Double edit: I'd been having image hosting issues, the image came out in triplicate! Removed the copies, sorry about that!

    Finning does help dissipate heat. This is why the fins are removed before cooking fish. Otherwise it will throw off the heat and not reach the proper cooking temperature. --Duglite

    piezo starter

    shield to keep wind from blowing the flame (a moving target is harder to focus)

    perhaps a lens like a lighthouse, and collapsible?

    mantle instead of flame?

    No Simon, I think up until the other day I hadn't ordered anything this year, I fell off the wagon this week ordered EagleTac D25A Ti and the brass carbide lamp plus 250gms of Calcium Carbide.
