Courtesy of the SWJ twitter feed thing, here is a link to a story about a compressed air cannon meant to protect merchantmen from the restless youth of the coast of the area that used to be Somalia.

This thing can launch clusters of golf balls at 450 mph. It is cool in a boys toys sort of way. It is interesting in that the world may be inching toward letting the merchantmen defend themselves, eventually maybe with lethal force.

It is also interesting in that it is reminiscent of the Holman Projector, which the British also invented.
