I don't see anything about producing precipitation but the idea is that it may be possible to create a "virtual" lightning rod in order to mitigate
However, unless the thunderheads are really low it's got a long way to go.
Similar to the principle of noise-canceling headphones, the energy loss of the primary laser beam and the energy supply from the dress laser beam
cancel each other out. In the lab, the researchers were able to extend the range of filament lasers tenfold – from about 10 inches to 7 feet.
They have been able to produce precipitation, conceptually.
Indeed, we observed that introducing filaments in a cloud chamber saturated with water vapor results in the spectacular condensation of a cloud,
which is very well visible with the bare eye. Surprisingly, the same effect can also be seen in sub-saturated conditions. Such unexpected droplet
stability and growth, in spite of relative humidity that is insufficient to balance the surface tension, is the sign of a specific mechanism at play
in the context of laser-induced water condensation. We expect that this mechanism implies both photochemistry initiated by the high intensity of the
incident laser pulses and oxidative chemistry due to the concentration of electrons up to 1015 cm-3.
These mechanisms, which trigger laser-induced nucleation in sub-saturated atmospheres, are not restricted to laboratory experiments. We have also
observed condensation in the real atmosphere. For that purpose, we launched the Teramobile beam vertically into the atmosphere over the city of
Berlin, Germany. We used a second, low-power laser beam as a probe overlapping with the filaments and detected its backscattering in a lidar
configuration. Although the atmosphere was sub-saturated (90-93 percent relative humidity), switching the Teramobile laser on increased the
backscattering from the filaments by a factor of 20. This effect can be unambiguously attributed to the formation of new particles and demonstrates
the effect of the laser.
Simulations performed by Matthew Mills at the University of Central Florida have shown that by scaling the new laser technology to atmospheric
proportions, the range of the laser filaments could reach 50 meters (165 feet) or more.
As the filaments travel through the air, they leave a channel of plasma in their wake – ionized molecules stripped of their electrons. Such plasma
channels could be used as a path of least resistance to attract and channel lightning bolts. Ultimately, this technology could be used to control
lightning bolts during a thunderstorm and steer them away from buildings.
There are certain people out there who would love to play god any way possible and at all costs. Mitigating lightning damage is the selling point to
us silly humans, when at some point lightning will strike twice in the same spot. Repeatedly, and with an agenda.
There will only be so many times our military could take out a target and call it an act of God.
Based on our successful results at the laboratory scale, we organized a field campaign during the summer of 2004 at the Langmuir Laboratory of
the New Mexico Tech, on South Baldy peak (3,200 m altitude). This permanent station dedicated to lightning studies is equipped with a network of
radiofrequency antenna capable of locating the electric activity of clouds with nanosecond-precision date stamping.
The network detected micro-discharges synchronized with the pulses from the Teramobile laser, showing that the conducting filaments generated by the
laser pointed toward the thundercloud have behaved like a metallic tip directed towards a loaded electrode: They have initiated corona discharges at
their tip. Our result provides observable evidence that allows us to optimize the laser parameters in future field campaigns. It therefore constitutes
a significant step toward the control of lightning by lasers.
Weather modding is real, as is the control of lightning. The laser can achieve both. They just need more fine tuning and a better delivery system.
