No, this is a different one.
Safely coiled in a reservoir of mineral oil, a wire of potassium
remains inert until a turn of the thumbwheel advances it out
of the reservoir, exposing it to the air. Reaction, combustion,
and ignition follow swiftly.

Because mineral oil isn't combustible at all... |

Fuelless lighter: broadcasts the radar signature of an enemy
aircraft. Stand next to something flammable, wait for the
airstrike, then light what you need to light in the flaming
rubble. |

Youtube people slicing up potassium shows it just sort of
tarnishing. You either need a more reactive metal, or an
ignition source. |

yep, you need cesium. Could add to the cost. |

I'm sure someone could devise a lighter that involves a
small guillotine style cheese grater; a block of oil protected
sodium; the means to spray water on the resulting
unprotected sodium particles which have been made
airborne by mechanically created, compressed air. Most
suitable for cooking croissants. |

Should be pretty exciting when the the reservoir
breaks and the oil leaks out... while in your pocket. |

So when the wire is pushed above the surface of the
oil, how long will it take for the film of oil to recede
and actually expose the wire to the air? Seems like it
would take a variable amount of time and would
require some patience. Then, wouldn't it burn very
quickly? Might be tough to light the cigarette. |

This is a MaxCo. product. The words "break" and
"leak" are not part of our vocabulary. Of course, this
causes problems when one of us needs to pop out of
the lab for five minutes to take a pee. |
