A paralyzing electro magnetic laser: future possibility or sheer fantasy?

In episode 134, the Techman is paralyzed, lifted off the ground and thumped back to the floor. Whether it’s electrostatic, electromagnetic or superconductor electricity reduced to a hand-held device, the concept seems valid, especially 144 years from now. Part of my challenge is to make this design fiction logical by pulling threads of current research and technology to extrapolate possible futures. Mind you, it’s not a prediction, but a possibility. Here is my thinking:

Keiji’s weapon assumes that at least four technologies come together sometime in the next 14 decades. Safe bet? To start with the beam has to penetrate the door and significantly stun the subject. This idea is not that far-fetched. Weapons like this are already on the drawing board. For instance, the military is currently working on something called laser-guided directed-energy weapons. They work like “artificial lightning” to disable human targets. According to Defense Update,

Laser-Induced Plasma Channel (LIPC) technology was developed by Ionatron to channel electrical energy through the air at the target. The interaction of the air and laser light at specific wavelength, causes light to break into filaments, which form a plasma channel that conducts the energy like a virtual wire. This technology can be adjusted for non-lethal or lethal use. “

The imaginative leap here is that the beam can penetrate the wall to find it’s target. Given the other advancements, I feel reasonably safe stretching on this one.

Next, you have to get the subject off the ground. Lifting a 200-pound human would require at least two technologies assisted by a third. First is a levitating superconductor. A levitating superconductor uses electric current from a superconductor to produce magnetic forces that could counter the force of gravity. According to physics.org:

“Like frogs, humans are about two-thirds water, so if you had a big enough Bitter electromagnet, there’s no reason why a human couldn’t be levitated diamagnetically. None of the frogs that have taken part in the diamagnetic levitation experiments have experienced any adverse effects, which bodes well for any future human guinea pigs.”

The other ingredient is a highly powerful magnet. If we had a superconductor with a few decades of refinement and miniaturization, it’s conceivable that it could produce magnetic forces counter to the force of gravity. 1

The final component would be the power source small enough to fit inside the weapon and carrying enough juice to generate the plasma, and magnetic field for at least fifteen seconds. Today, you can buy a million-volt stun device on Amazon.com for around $50 and thyristor semiconductor technology could help ramp up the power surge necessary to sustain the arc.  Obviously, I’m not an engineer, but if you are, please feel free to chime in.
