Ball lightning has been the subject of much scientific scrutiny over the years. And, as with many powerful natural phenomena, the question arises: "Can we turn it into a weapon?" Peculiar as it may seem, that's exactly what some researchers are working on -- even though it hasn't even been properly replicated in the laboratory yet.

In the mid-'60s, the U.S. military started exploring ways that the phenomenon might be weaponized. Take this 1965 Defense Technical Information Center report on Survey of Kugelblitz Theories For Electromagnetic Incendiaries, (Kugelblitz is German for ball lighting). The document summarizes and evaluates the ball lightning theories then prevalent, and recommends "a theoretical and experimental Kugelblitz program... as a means of developing the theory into a weapons application." This led to an Air Force program

However, some years later scientist Dr. Paul Koloc was looking at methods of containing high-temperature plasma during nuclear fusion. There are many schemes for containing plasma in donut-shaped magnetic fields using a device called a Tokomak. Koloc's insight was that, under the right conditions, a donut-shaped mass of moving plasma would generate the required fields for containment itself. No Tokomak would be required for this "plasmoid," which would be completely stable and self-sustaining. It is a very close equivalent of the smoke ring -- another type of dynamic "vortex ring," which remains stable over a period of time, unlike an unstructured cloud of smoke.

In the '80s, Koloc's team succeeded in creating small, short-lived plasmoids from "chicken egg to softball" size in the laboratory. It was a good start, but not enough to convince the world that he's right about ball lightning. Ultimately the work might lead to a means of containing nuclear fusion... but there were some engineering challenges to

However, in 2002, Koloc's company, Prometheus II, briefly obtained funding from the Missile Defence Agency. The aim was to create stable 'magnetoplasmoids' a foot in diameter which would last between one and five seconds. In the subsequent phase, the magnetoplasmoid would be compressed and accelerate to two hundred kilometers a second. This "encapsulated EMP bullet" would make an idea anti-missile weapon, generating an intense

Koloc called the weapon "Phased Hyper-Acceleration for Shock, EMP, and Radiation" -- PHASER.
"It can be used for a range of purposes from stunning personnel to destroying the functionality of electronically operated devices, smaller rockets, vehicles and packages that represent an immediate threat to the United States," he wrote. "This dial-able PHASER weapon can be set on 'Stun' or dialed down, selecting a non-lethal level for persons needed for later interrogation... One mundane application for law enforcement

Nothing seems to have resulted after the Phase I contract, so I contacted Koloc to see how his research had progressed. He confirmed that they had successfully formed plasmoids a foot in diameter, but that these could not be made sufficiently stable.
To make it work and overcome the stability problem, they need a device known as a "fast rising parallel plate transmission line." There was not enough funding for this and the company is still trying to raise funds.
"Once the re-engineered formation system becomes operational, we will proceed to form plasmoids of approximately 35 to 45 centimeters in diameter with a stable lifetime of from one to thirty seconds," says Prometheus II Vice President D. M. Cooper. "The plasmoids should be rugged and energetic, and should attain quiescence (thus becoming very stable) within two or three milliseconds of the formation pulse. The plasmoids will be useful for energy applications even if the military applications are not pursued."

Ball lighting is still mysterious 200 years later… and the next time a warship gets struck by weird fireballs they will probably be as baffled as were the sailors aboard the HMS Warren Hastings.
