You should build these for hikers and campers. I suggest getting a kickstarter page and pre-sell these to donors. It looks amazingly simple and lightweight enough to attract the attention of so-called doomsday preppers.
Wow so cool
I have made a Deer Antler Fire Piston, with wood piston and rubber "O" ring, it would not work, then I tried a metal rod, no good, then metal tube and metal rod, no spark, I tried waxed string gasket, still no good!
I finally got one to work, a Maglite Flashlight and wood piston w/ rubber "O" ring. Still trying to get the others to work. Not sure why the others won't spark. Thanks for yours. Great for showing young scouts the magic of it!
Interesting. This is the same principle Diesel engines use for ignition. compressing the air/fuel mixture to generate heat instead of spark plugs. Cool!
Wow! nice one! I tried this with an old mini Mag light.
can't get it to fire, :-(.
I will look for these components !
