I'd like to make an explanation for scientific phenomenon that has been use in this kind of technology without accidentally suggesting that the technologies in my world are advanced enough for space faring age.
Let's call this weapon "Vacuum-turbulence Particle Accelerator". It works by creating the energy storm that push the atmosphere outward, forming a vacuum cylinder with no air to disperse or weaken any energy particle you want to shoot through it.
This is only to make a nod to the scientific phenomenon that energy weapon have trouble travelling through the atmosphere, making an impression that you'd better spent the energy pushing the atmospheric pressure instead of brute force the energy particle through the air wall. This is also to give a cool weapon for a military force with high tech but crude, cheap, down-to-earth, industrial theme with current day bullets and missiles compared to the cyberpunk/biopunk/biomechanical/low key eldritch theme of their enemy.
I'd like some help in giving an explanation for the vacuum creation technology. What scientific phenomenon can work with this kind of thing?
