Anti-Sanecraft ARTillery Cannon Is Farm Boy Engineering At Its Finest

The term “just enough knowledge to be dangerous” comes immediately to mind with this one. The official description is “a large scale pan and tilt propane Flame Effect” but that hardly does this thing justice. The Anti-Sanecraft ARTillery Cannon is a three-barrel fire cannon that can move around like its namesake and launch massive propane bursts from two 1″ diameter barrels. The third barrel is somewhat special, it is constructed of stronger steel and can be pre-fed with oxygen to create one massive intense propane-O2 mixed fire burst.

The trick about the whole thing is that when oxygen and propane are mixed it is a highly volatile and dangerous thing, in a closed space they classify as an explosive. Instead oxygen is filled directly into the open ended barrel separately and is allowed to sit until propane fires it out. This mixes the two fuels in the open air where it is safer and far away from any bystanders. We would not suggest you try this at all ever, as the effect was so loud during the Transformus festival that neighbors, miles away from the large festival ground, were complaining  about rattling windows. This is the kind of place where several thousand watt sound systems are pushed near the red with no issue, just to give a bit of a comparison.

We can’t seem to find a video of this thing in action either [Beyond Joy] just posted a video of this crazy contraption in action (without the O2 effect), check it out after the jump! Don’t forget to check the facebook photo album for all the NPT pipe fitting action, (warning some images of the phallic controls are very mildly NSFW).

    1. Hydrogen: 286 kJ/mol
      Propane: ~2.192 MJ/mol

      However, hydrogen is 35 times less dense, so propane has a high energy density per unit volume, but hydrogen has a high energy density per unit mass.

  1. The shots you are seeing are single barrel shots only. None of those are from the middle barrel (where the 2 outer barrel are combined into one big one). Theres no boom because these shots are pure propane. The oxygen isnt being used. This video doesnt show near the size fire this thing is capable of.
