Well, I'd certainly want one of these if I was an officer aboard a spacecraft and we were directed to check out a derelict alien spacecraft.

Otherwise, bad idea...
100 FARM USES:
1. Burn down the @#$% farmhouse
2. Burn down the @#$% barn...
Re: 100 FARM USES:
8. Environmentally friendly spider remover.

9. Raking leaves and pine straw now a thing of the past.
I find myself hoping that below this was an ad for some sort of firefighting device. This thing may kill weeds, but how do you STOP it once the entire field goes up in flames?
This is probably my second stupid question for today, but how do you burn air?

(I tried google and it was uninformative.)
Oxygen has to be present for combustion to occur. Hence, you'll never see explosions in space.
OK, I did know that. But I'm still confused at the "Burns 6% Kerosene, 94% Air" part. Maybe it's just the way they're phrasing it that I don't get.
in many cases, liquid fuel does not burn, only fuel in a vapor form. this is why your car uses a mixture of a lot of compressed air and a fine mist of gasonline to combust in your cylinders. a popular experiment in high school science is to put out a match or candle by dousing it with gasoline.

i'm assuming they're saying the same thing here. it's probably more literal than we are used to (car manufacturers would probably get in trouble if they said their normal cars ran "primarily on compressed air"), but it's accurate nonetheless.
Ah, OK, that makes sense. Though it looks to me like they're implying that you're saving on kerosene by burning air when actually that's just how combustion works. But hey, it's advertising.

Thanks you for the explanation.
I bet it's handy for mucking out stalls. Plus, great for starting bonfires for barn-raisings, harvest dances, quilting bees, and other farm funtimes! Just add marshmallows, lol.


I WANT ONE
Can I borrow it? I have some kids that won't get off my lawn and I'm allergic to grass pollen.
Yeah, kill your weeds and everything else in the field! haha I'm interested in what all the uses are...
You make it sound like torching a field is such a bad thing. The soot and ash are fertilizer.

"Fire is bright and fire is clean." -Captain Beatty, Fahrenheit 451
a 1947 classified-style ad in the back of modern mechanix says the following about it:

"Modern Flame Thrower destroys weeds, splits rocks, disinfects, irrigates, 100 practical uses, 4 gal. tank, torch, hose, $22 express collect.Valuable literature Free. Sine Equipment 16S(?) Quakertown, Pa."

and a similar 1946 ad says:

"Kill all weeds with 2000 degree flame. Famous fire gun sterilizes, thaws, incinerates, disinfects. Works like a blowtorch, burns kerosene, mostly air. Economical, safe, sure. Free literature tells how. Write Sine Equipment. S376 Quakertwon, Pa."

another 1946 ad adds "destroys tree stumps" and "heats water in stock tanks" to the list of advantages.

so at least we know some of the 100 uses they meant it for other than burning stuff and burning stuff and burning stuff.
I wouldn't want to see the lawsuits once *this* thing starts malfunctioning!

But seriously, they just don't make zombie- and vampire-repellants like they used to!
My ex-husband had a couple that he got from his dad, but I don't think he ever used them. In Texas they are called "Pear Burners". You run the flame over prickly pear cactus just enough to singe off the thorns but not enough to char them. (Prickly pears don't burn easy, they hold a lot of water.) Then the cattle will eat the prickly-less cactus. Apparently, the cattle love cactus brulee -- he says they would follow his dad and uncle around the pasture, barely waiting for the cactus to cool off to eat them.
"Halloween is coming- great for burning the witches who ruined your crops with the evil eye!"
where i live "controlled burns" are quite common to keep the chaparral in check, so this seems pretty useful actually. . not to say that those controlled burns don't occasionally get out of control and start straight up brushfires :/
