    On board ship, many tanks only have a bolted down manhole cover on deck, as means of access.
    Especially in tropics, it can be a real oven inside those tanks.
    Also, we usually don't know how long since the last time tank was opened, and if there is sufficient oxygen in the air to support life.
    You can test with a flame safety lamp. sufficient O2 to sustain a flame, will sustain life.

    but normally, we just drop an air hose in the tank, with a valve on the end.
    The valve is just opened so there is a weep of air coming from it.

    In half an hour, the tank is cool and the air fresh.

    The MASH tents had pockets sewn into the side walls, held an aluminum venturi, size of a garden hose nozzle.
    An engine powered rubber tired air compressor was parked remote from the tents, and compressed air fed to the venturis via large air hoses hooked to manifolds with a dozen smaller air hoses hooked from the manifolds to tent venturis.
    Dropped temperature inside by 15 to 20 degrees.
    Injured soldiers healed quicker when comfortable.

    Very, very interesting. Had no idea, especially about the MASH part.

    In your case, have you yet figured out how to size your system (size and quantity of nozzles, type of compressed air to drive it, etc)? For example, I went to that website, and they have about 5-6 different size nozzles, beginning at 3/4" for about $83.

    One thing struck me as odd about the info on that nozzle website. For a device intended to cool, most of the info there related to high temperature tolerance vs. cooling ability. Not sure what that was about.

    I'll make my own.

    IMPORTANT! 'OILESS" COMPRESSOR ONLY unless you want carbon monoxide poisoning!

    Tubes are installed near your face in bunks and seating.

    Fans cool your body, while the weep of compressed air creates a refrigerated bubble around your head.

    Fill up air tanks prior to going to bed, should be sufficient air for two sleepers for 8 hours.

    Use during day at desk or workbench or reading chair.

    Not air conditioning entire boat, just your face.

    Normal fans provide ventilation for body comfort.

    While the system is cheap and simple, it doesn't need to be crude or ugly.
    A visit to the local U-PULL IT auto scrap yard, and depending on your negotiating skills, will get you some elegant fittings and not much cost.

    This hand crank lantern at Harbor Freight, 12$, when disassembled, has inside, a 12 LED bulb cluster, a 4 way push button switch, lights 4 LEDs, 8 LEDs, or 12 LEDs, and OFF, and a joule thief circuit, that gives you a lot of power from a little electricity. 3.5 volts
    Also 3 rechargeable batteries in a cluster, and a hand cranked geartrain speed enhanced DC generator.
    And reflectors and clear conical lens

    It can easily be reassembled into a nice looking compass binnacle, compass protected inside, with emergency hand generated compass light, but with battery power also, for most of the time.
    Just cover the LEDs with a transparent red plastic cover. Or paint 8 with fingernail red polish.

    Paint it gold or brass or antique bronze.

    It's water resistant, but could be made water proof, with silicone caulk.

    Struggling with fitting the Dometic ammonia fridge.
    Working alone is awkward at times.

    It will fit, a tight fit. Need a bigger hammer!
    A PERSUADER! :D

    No luck with the peltier chip heating the ammonia.

    So, when I don't have electricity, I'll use this to power the fridge:

    https://snapguide.com/guides/make-a-45-day-emergency-candle-out-of-crisco/

    Plan to use Crisco candles in my SeaSwing stoves, too.

    Open flame? Yes, needs care. Snuff before going to sleep. Less dangerous than propane though! Crisco ain't explosive!

    Easy to smother, and the snap on lid keeps from spilling when not burning and keeps out rodents and insects. Wide based can is stable, not tippy.
    Burns hotter than sterno and is cheaper. Cleaner than kerosene, too. No smoke or soot or funky smell.


    Instruction above claims Crisco originally marketed as a canned candle.

    Logo might be a clue.

    One thing Crisco should NEVER be used for, is a coitus lubricant! It's SHORTENING, man! Diminishing returns!

    Hydrocarbon based heat; I like it. It is the wave of the future.

    I recommend transferring the Crisco to a can with metal wall. Cardboard wall can catch fire.

    RENEWABLE energy Hoyte.
    It's vegetable oil. GREEN vegetable oil, except in color.

    The can idea is much appreciated.
    In fact, I'll look for plastic lids sized to fit tuna cans.
    I deliberately empty lot's of tuna cans.
    Maybe cake icing plastic tub lids would fit.
    I empty lots of those, too.
    I don't buy candy with exception of bite size tootsie rolls, cinnamon hots, and marshmallows, I use in cooking.
    Prefer to just buy cake icings, nuts, shredded coconut, dried fruits, peanut butter, jellies, and marmalades, for my sweets.
    A spoon full of any of those, satisfies my sweet tooth for hours.

    Tuna cans would make great cooking candles filled with Crisco.
    Stable broad base relative to height, and limited fuel capacity, means safer.
    Small shallow means can get them close to the pot bottom, for good heat concentration.
    Where with a deep tub like a Crisco can, once candle burns most of fuel, flames gonna be deep down inside.

    But....where am I gonna get tuna cans with candles as part of their logo?
    So I know what to use them for?

    Great idea inspite of logo shortcomings. Thanks!

    Macaroons, best kind.
    Can of sweetened condensed milk boiled unopened in a pan of water for an hour.
    Let cool till can handle but still warm.
    Open can, pour out and mix the caramelized milk inside with shredded coconut.
    Drop big spoonfulls of mixture on greased cookie sheet.
    Poke an unwrapped bite size tootsie roll in the middle of each cookie.
    Toast in oven. Cool. Eat!
    Tada!

    Candied apples or sweet potatoes or corn or carrots or onions?
    Cook with a few marshmallows and a spoon full of red hots dots.
    EEEYHAW!

    Another candied dish worth making.
    Boil smoked sausage or Polish Kielbasa in a cup of ginger ale till it all turns to glaze on the meat!.
    Hohoho!

    Oh, another!
    Cherry preserves from the marmalade section.
    Spoon full on each of your pork chops or sliced roasted pork or pork tenderloin, with a sprinkle of slivered almonds! Impressive!
    In case the president or king or your mother-in-law is coming to dinner.

    The kids made camp cook stoves by winding cardboard about 6 turns into tuna cans and filling with melted paraffin. Cardboard stuck up about an eighth of an inch. It was more than a candle but less than a conflagration.

    When cool it could be stowed in a backpack.

    Sounds good for a griddle needing a wide flame. For made from scratch tortillas toasting.

    Icing tub lids are just a teeny bit oversized.
    Won't snap on the tuna can, just sits on top. Rats!

    Good morning, Yobarnacle.

    Just tie some plastic wrap or piece of grocery bag around the brim with a scrap of insulated wire twisted on.

    That's One possibility.
    Was looking through my junk box, and found some unrelated items that I repurposed.
    Assembled this in a hurry. So kinda crude.
    It might serve as a simple smothering tuna can lid and keeps critters out. No joke! (something simpler, a lie. I didn't make this.)

    But don't have parts for more than just one, and need several tuna can candles. 08D

    Alternative, is the family size tuna cans might find ready fit caps from other cans. Like the one pound Crisco can lid.
    I'll check next time at grocery store.
    Really, this is such a minor detail. :)
    something will turn up.

    Try laying it on an empty tuna can and running a heat gun around the edges. It just may shrink enough to seal.

    that's a thought. :)

    08D I used as emoticon above, supposed to be faked innocence. A slipping halo over wide innocent eyes and a wolfish grin.
    Too bad it doesn't make a caricature.
