Periodically generates a burst of kinetic energy from the centre of the anomaly which pushes all matter out of the area with considerable force. Periodically generates a wall of energy at the borders of the anomaly. These walls do not let anything pass through, and if they appear while an object lies across the border it will be cut in two. Should the two events occur simultaneously objects inside the anomaly will be pushed out at speed and hit the wall, with likely damaging effects.

Find a way to generate the wall or energy burst outside of the bounds of an anomaly. Find a way to make the wall portable.

Both the wall and the energy wave have been studied, and the basic physics of how they operate is known.
