    You seem like the kind of person who knows a thing or two about massive cannons...

    What do you think of my idea to build a 12"(diameter) air cannon to shoot ~35 pound water balloons with a muzzle energy of ~184,000 foot-pounds?

     that depends on how u build ur air cannon. I could easily build a stronger cannon then this. The cannon is VERY powerful but there can be more powerful. Depends on how u make ur cannon.

    FINALLY an ADVANCED combustion cannon on instructables. all the others are lame pill bottle ones that shoot like 10 metres.

    what stops the combustion from burning up the internal mechanisms such as the wires, fans, wood, and pvc

     The "explosion" inside the chamber just makes pressure not so much heat. This results in no melting and burning of internal parts.

    Me and a friend of mine made one of these, with just 4 small puff's of hairspray we launched a energy drink molotov about 100m far away (energydrink molotov: a empty energydrink can, filled with gasoline and then add a small piece of gasoline drenched cloth in the hole, light the cloth and launch it within about 20 secs of lighting it) We did this at an old abandoned mine so we couldn't put anything on fire :) Energydrink cans fitted amazingly into ours ;D, or those mini cola cans, their the same diametre as energy drink cans, but smaller! Ps: We made interchangeable barrels, you could just "unscrew" em like a silencer and change the diameter of the barrel :) we can shoot from marbles to tennis balls ;D

    Mixes the fuel and air together so the explosion in the chamber is equal and spreads. Its actually pretty useful.
