I'm no physicist
Sarcasmo wants one of these. This leads me to wonder why: - This is superior to a trained monkey with a blowtorch who will smite your enemies
- Photons or other electromagnetic-wave-based weapons which don't "excite" their target, but obliterate it with force, don't have to obey conservation of momentum. That is, if it blows up a moon, rather than heating it, why doesn't it have a recoil that pushes your shoulder through the Earth?
Subtlety is not one of my strengths
