If you’ve read my Records of the Argos series, you know plasma cannons are some of the most formidable weapons in my fictional universe. They spit searing bolts of superheated matter across the void, tearing through shields and armor alike. But it raises an interesting question: can we build a plasma cannon like this in real life?

Let’s take a closer look at plasma, the challenges of controlling it, and how close we might actually be to wielding a “real” plasma cannon.
What Exactly Is Plasma?
Plasma is often called the “fourth state of matter,” alongside solid, liquid, and gas. It’s created when a gas is heated or energized enough that electrons break free from their atoms, producing a soup of charged particles. You see plasma in neon lights, fluorescent bulbs, and, of course, in stars.
Because plasma is both incredibly hot and electrically conductive, it’s not something you can hold in your hand. Containing it requires strong magnetic fields or other advanced methods. That makes it perfect for science fiction weaponry—and a real headache for scientists trying to build one here on Earth.
The Problems with Building a Plasma Cannon
A plasma cannon, in theory, would need to:
1. Generate plasma quickly, probably by superheating a gas or stripping electrons from atoms.
2. Contain and direct it so it doesn’t just dissipate. Plasma likes to spread out, and without containment, it cools too quickly.
3. Fire it at a target at high speed while maintaining energy density.
Right away, you can see the hurdles. Plasma doesn’t “fly” through open air very well. It disperses, cools, or reacts with surrounding matter. In space, it would disperse even faster without containment. That’s why in my stories, plasma cannons rely on advanced magnetic fields to hold and project plasma bolts until impact.
Are We Close in the Real World?
Scientists and engineers have dabbled with technologies that hint at plasma weaponry:
– Plasma torches already exist for cutting metals, producing streams hot enough to slice through steel.
– Electromagnetic plasma accelerators (a cousin to railguns) are tested in defense labs. They use plasma to accelerate projectiles or form part of a destructive pulse.
– Directed energy weapons like high-powered lasers can create plasma effects when they strike targets, though they don’t fire plasma directly.

None of these, however, are true “plasma cannons” as science fiction imagines them. Right now, the energy requirements alone would be staggering. That is now far beyond even the most advanced fusion reactors we’ve designed.
The Role of Zero-Point Energy
In my fictional universe, power problems are solved through zero-point energy (ZPE). That is, a technology that taps into the quantum fluctuations of space itself. ZPE provides virtually limitless power. It allows ships like the Argos to generate, contain, and project plasma bolts without exhausting their energy reserves.
Imagine drawing power not from a reactor core but from the very vacuum of space.

In theory, ZPE could deliver the near-instantaneous bursts of power required to superheat matter into plasma and sustain the magnetic fields needed to hold it together during flight. It’s a real physics concept. Quantum mechanics tells us that even a perfect vacuum is never truly empty—but remains well beyond our engineering reach.
For humanity to build something similar, we would need both the breakthroughs in fusion containment and a method of safely harnessing zero-point fluctuations. Such a step could rewrite the laws of energy production as we know them.
Why Plasma Cannons Work in My Stories
In Records of the Argos, plasma cannons aren’t just flashy weapons. They represent the ingenuity and adaptability of the crews who use them. The Argos may be an older ship, but with upgraded plasma weaponry powered by fusion and stabilized through zero-point energy, it can stand toe-to-toe with far more advanced adversaries.
Zero-point energy also symbolizes one of the central themes in my writing: the human drive to reach beyond what seems possible, to turn theory into reality through courage and creativity.
Final Thoughts
So, could we ever build a real plasma cannon? Science says: not yet. But the idea sparks our imagination and challenges us to think about what future energy breakthroughs—perhaps even ZPE—might one day allow. That’s the sweet spot of science fiction: where real science brushes up against infinite possibility.
What do you think? If we could build one, should we? Or is plasma best left to the battles of The Argos and her crew?
FYI, there is something called the Lorentz Cannon that some call a plasma cannon, but it is not. You can watch the YouTube video HERE.
