Now that's a nail gun

I've seen some big nail guns including one that took up half a pallet and I couldn't lift, which oddly enough was designed exactly like the hand held ones but scaled up, but this one takes the cake. It shoots 20 foot nails into the dirt

Looking at the patents it has a very interesting design. Looks like it has a sabot with a lip on the side that doubles as a burst disk. They pump air into a chamber that is sealed at the front by the sabot and at the back by a smaller second disk on the nail. When the sabot breaks free it carries the nail forward from the front and the pressure keeps the rear disk sealed until the end of the nail rips it off, and the sabot is stripped with a sabot stripper in the front.
