That should be true if the sword's efficiency is based on the particles. However, it's no wonder it stayed active as long as it did. After all, the dragoon system (or whatever it was called) stays active for a really long time after completely detaching from the main unit. So, the sword could stay active for half an hour for all we know.Originally Posted by Ryllharu
Still, the Throne keeps shooting their GN particles around so much that it should be no problem to study it's properties as much as they want. Just place the monitors and meters near some military base and the Throne will be there eventually to give all the measurement imaginable. Even if they can't replicate the solar furnace, apparently, without a really long trip to a distant planet, they might be able to think of some counter measures and such based on the results. Also, the sword itself might still reveal something about how materials react to the GN particles. After all, the Gundams seem to operate perfectly in the middle of the highest concentration whereas regular electronics have problems.
