I doubt many people would be too keen on reversing a truck into a wall.

It also wouldn't be as "safe" to do so. A truck doing that is a lot of momentum, and it would probably continue through the wall itself.

That is pretty cool. It looks like it could very well be a large coaxial diaphragm or piston valve. Could be a toolies style piston as well

Awesome! Its hard to see how it works. (what kind of valve?)

Its very compact for its power.

Anything with a bore measured in feet and running on hundreds of psi is going to have quite a lot of bang for it's overall length.

Impressive device, but as far as practicality is concerned I think this would be a much better idea.

Of course, all of these ideas depend on the wall being structurally sound enough to still stay up with a hole in them.

Try that at some houses I've seen, and instead of a house with a hole in it's wall, you'd be left with a pile of rubble with some hostages and terrorists buried under it.

Watch that future weapons video. That's the way the enemy would be expecting you to come in so they could cover it or booby trap it. Come in through the wall and they have no idea where you're coming from!

Im petty sure if you stuck that future weapons thing on a door the people waiting there to shoot you up would be in no fit state to do so. They would have a brass effect door knocker embedded in their forehead.

Before I forget here's a more useful side-on picture of the cannon:

I'm wondering if that's a piston valve lurking at the top there... These photographers have no idea of how to take photos for those interested in the interesting bits i.e. the back end, not looking down a barrel... :P

If the quality of the video is anything to go by, the valve is probably made of a rubber glove over a pringles tube...

I could definatly do them a proper video...

Im not sure if a rubber glove and a pringles tube can be beaten when it comes to high pressure gas guns....
